    The nature of back pain in a general adult population: A longitudal study2000Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The purpose of this thesis was to study in a general adult population the prevalence and incidence of back trouble, predictive factors for new episodes of back pain, new sick leave episodes, and factors important for recovery from back pain. The pain drawing method was used in an epidemiological survey to identify pain in the entire back area. The bias that knowledge of back pain history has on the interpretation of pain drawings was studied in a separate study.

    The cross-sectional main study population consisted of 2000 individuals aged 20-59 years. A prospective survey was conducted after one year on the study population of factors important for new sick leave, new back pain episodes and recovery and after five years on two age strata of factors important for retaining back health. After ten years the number of disability pensions granted for back pain during the time period was studied. The socio-demographic and work-related factors that predicted disability pension were studied.

    The prevalence of back pain was found to be 23%. Back pain with radiation was reported by 40%, according to the pain drawings. Only 4% reported localised neck pain. Sick leave was reported by 12% of those with back pain. The more generalised pain pattern suggested that back pain is more than a local back pain problem.

    The one-year incidence of new back pain was 24%. Seventy-nine percent of the episodes lasted less than 2 months. A history of previous back pain predicted new back pain episodes, while stress at work and low work satisfaction was associated factors. Low age, more qualified work tasks and residence predicted recovery from back pain. New sick leave periods were predicted by unqualified work tasks, pain debut at work, previous back pain history and pain at the primary survey.

    The clinical findings in the group with pain at the primary survey showed that the absence of tenderness in the trapezium muscle was the strongest predictor of recovery. It was also found that straighter lordosis and restricted mobility in the cervical spine were associated with new sick leaves in the prospective year.

    The pain drawing study showed that knowledge of the pain history affected the interpretation and reliability of the pain drawing evaluation.

    The five-year survey showed that absence of physical load in the old age group and absence of psychological stress at work in the younger age group predicted retained back health.

    The study of disabilities granted on the grounds of back pain during ten prospective years has shown that age over 40, sick leave at the primary survey together with perceiving the work tasks as meaningless predicted disability pension.

    The results of this thesis suggest that back pain should be seen as arecurrent problem, where previous episodes strongly predict new episodes. The complex nature of back pain as a health problem suggests that the rehabilitation should be individualised and include both work-related factors as well as a wide range of factors not related to paid work.

    Abstract [en]

    OBJECTIVES: To investigate the prevalence of back pain in a general population aged between 20 and 59 years.

    POPULATION: A representative sample of 2000 individuals from Ostergotland County, Sweden (population 400,000).

    STUDY DESIGN: Cross-sectional study using a questionnaire including the pain drawing.

    RESULTS: The observed point prevalence was 28% (95% confidence interval 26-31%). The adjusted prevalence taking into account the non-responders was 23% (21-25%). Lumbar pain with radiation was reported by 40%, while 4% had only cervical pain with radiation. Twelve per cent were on sick-leave due to back pain. Activity of daily life was affected mainly in the group of men aged 40-59 and only in household tasks. The back problems did not affect social activity.

    CONCLUSIONS: The prevalence of back problems in the vocational ages was found to be 23%. Only small parts of a pain population are on sick-leave or have changed working tasks because of back problems. The distribution of pain in most cases is combined with radiation to extremities and not isolated to a single region. The combination of different localisations shows the pain problem to be more than just a "low back" problem.

    Abstract [en]

    To assess whether the clinical knowledge of the treating surgeon had any effect on the reliability of the pain-drawing evaluation, drawings from 50 low-back pain patients were evaluated by the treating surgeon and by three colleagues who had no clinical knowledge of the patient. The evaluation was repeated after 10 days. The treating surgeons were also blinded to clinical data. The kappa value in the evaluation when the surgeon had clinical knowledge of the patient was lower (0.29 (95% CI 0.13–0.45)) than the kappa value in the evaluations made without clinical knowledge (0.60 (CI 0.45–0.75)). The differences observed in interobserver reliability between open and blind evaluations suggest that clinical knowledge of a patient influences the evaluation of the pain drawings.

    Abstract [en]

    Objective - To study the incidence of self-reported hack pain in a general population and to identify risk factors for sick leave and factors associated with recovery from back pain.

    Population - A cross-sectional sample (n=1344) of a general adult population.

    Setting - In a semi-urban Swedish county.

    Design - One-year prospective study of a single cohort.

    Main outcome measures - The incidence of back pain, risk factors for sick leave, factors predisposing for recovery.

    Results - The incidence of back pain was 24 % (95% C.I. 22% to 27%). 79% of the pain episodes lasted less than two months. History of previous back pain predisposed to developing new episodes of back pain, while stress at work combined with low work satisfaction were associated factors. Factors predisposing to recovery were young age, skilled work, and living in the countryside. Unskilled work, pain debut at work, previous history and back pain at the start of the study were factors predisposing to sick listing for back pain. Long-term sick leave was predisposed by previous history of back pain and ongoing back pain at the start of the study.

    Abstract [en]

    Objective - To investigate whether physical examination findings can be used in predicting recovery from back pain and new episodes of sick leave.

    Design - One-year prospective study of a single cohort.

    Settings - Semi-rural Swedish county.

    Population - A cross-section of a general population with back pain (207 women, 176 men) between 20 and 59 years of age.

    Main outcome measures - Cumulative incidence of sick leave due to back pain, cumulative incidence of sick leave due to back pain > 30 days, incidence of recovery from back pain.

    Results - For recovery from pain, the absence of tenderness in the trapezius muscle (OR 0.33, CI 0.1-0.5) was predictive. New sick leave was predicted by tenderness in the trapezius muscle (OR 2.67, CI 1.5-4.9), and had a tendency to be associated with a flattened lumbar lordosis and a restricted cervical range of motion. For long-term sick leave, the same findings and also observation of scoliosis (OR 3.44, CI 1.1-10.5) were predictive.

    Conclusion - There are subgroups with back pain predisposed to development of more persistent symptoms and a higher risk for sick-listing.

    Abstract [en]

    Factors important for avoiding back disorders in different age-groups have seldom been compared and studied over time. We therefore set out to study age-related differences in socio-economic and work-related factors associated with the absence of back disorders in a 5-year comparative cohort study using a mailed questionnaire. Two subgroups (aged 25-34 and 54-59 years) derived from a representative sample of the Swedish population were followed at baseline, 1 year and 5 years. Questions were asked about the duration of back pain episodes, relapses, work changes and work satisfaction. A work adaptability, partnership, growth, affection, resolve (APGAR) score was included in the final questionnaire. Multivariate logistic regression was used to identify factors predicting the absence of back disorders. Absence of physically heavy work predicted an absence of back disorders [odds ratio (OR), 2.86, 95% confidence interval (CI), 1.3-6.3] in the older group. In the younger age-group, the absence of stressful work predicted absence of back disorders (OR, 2.0, 95% CI, 1.1-3.6). Thirty-seven per cent of the younger age-group and 43% of the older age-group did not experience any back pain episodes during the study period. The exploratory work APGAR scores indicated that back disorders were only associated with lower work satisfaction in the older group. The analyses point out the importance of avoiding perceived psychological stress in the young and avoiding perceived physically heavy work in the older age-group for avoiding back disorders. The results suggest a need for different programmes at workplaces to avoid back disorders depending on the age of the employees concerned.

    Abstract [en]

    Back pain contributes to a large number of disability pensions. The process toward disability is not well understood. In a 10-year (1988-1998) prospective study of a single cohort (n=1902) representative of the general adult population in a semi-nrban Swedish county, the incidence of disability pensions based on back pain was studied. Socio-demographic and work-related risk factors for disability pension were analysed.

    Eigbt percent of respondents to a baseline survey (n=1344) and 10% of the non-respondents (n=558) were granted full-time disability pension on back pain diagnosis during the 10-year period. Age over 40, low professional status, primary sick leave because of back pain and the perception of work tasks as unsatisfying were found to predict disability.

    Disability pension granted due to back pain appears to have a variation over time and is affected by both social insurance and work-related factors.

    Heterotopic bone formation following total hip arthroplasty: clinical and experimental studies using NSAID and patelet-derived growth factor1995Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    A consecutive series of 104 Lubinus IP arthroplasties was retrospectively studied with regard to heterotopic bone formation (HBF). Fifty-three cases were treated for 10 ± 2 days postoperatively with the NSAID oxyphenbutazone. Radiological follow up three months postoperatively showed significant HBF (;;,20mm) in 21 patients in the untreated and in none in the treated group (p<O.OOl). Some degree ofHBF was found in 9 of the treated patients and in 27 of those untreated (p<O.OOl). Since important factors in HBF development were kept constant in both groups, the difference in incidence of HBF was assumed to depend on the oxyphenbutazone treatment.

    In another retrospective series, all except 4 of 220 total hip arthroplasties were treated for about two weeks with oxyphenbutazone. Charnley (C), McKee-Farrar (M) and Bmnswik (B) arthroplasty were studied. The incidence ofHBF in the entire series was low (15%). Some degree ofHBF was seen in 37% (C), 8.3% (M) and 8.5% (B). Significant HBF (;;, 20mm) was seen in 30% (C), 4,8%(M) and 1,2% (B). Five years postoperatively,no significant functional differences were seen between the patients with HBF and those without HBF. Trochanter osteotomy (C) seemed to be the reason for the significantly higher incidence of HBF for C than for M and B, respectively (p<O.OOl).

    In a randomized, double-blind, placebo-controlled clinical study of 100 Lubinus SP Il arthroplasties diclofenac treatment (50mgx3) almost completely abolished substantial HBF (;;,20mm). In the placebo group, significant HBF was found in 3 3 of a total of 4 7 hips, compared to 1 of a total of 46 hips in the treated group (p<O.OOl). Functional scores 1-2 years postoperatively were not affected by HBF.

    PDGF (20 ng/ml) and induction of heterotopic new woven bone was studied in rats. The agent was administered locally and continuously for two weeks by means of mini-osmotic pumps inserted subcutaneously. The PDGF reached 6-mm long pieces of demineralized rat femur implanted into gluteal muscle pouches. Each rat had a contralateral control piece implanted. PDGF increased the ash-weights of the samples significantly (p<0.05).

    Using the same type of administration system, the effects ofa very small total dose (40 ng) of diclofenac on induction of new woven bone, were studied. The diclofenac treated samples showed significantly reduced ashweights (p<0.05).

    The effects of 0-200 11g diclofenac/ml after 48 h on the proliferation of cultured, serum starved human fibroblasts stimulated or not stimulated with PDGF, were studied using [3H]-thymidine. A dose-dependent inhibition was obvious at 211g/ml and significant at 5 11g/ml (p<0.05) both in the presence and in the absence of PDGF. The inhibiting effect occurred during the first 24 h of the PDGF-induced mitogenic signal. TRlTC-labelled phalloidin was used to study early and late effects of diclofenac on the organization of actin. Typical PDGF-induced changes of the actin cytoskeleton were inhibited by diclofenac. Diclofenac also caused the cells to assume a more epitheloidlike shape.

    The effects of diclofenac (50 l!g/ml) on whole cell appearance of human, serum starved fibroblasts, stimulated or not stimulated with PDGF, were studied using scanning electron microscopy. Cellular effects equivalentto the actin organization changes were detected at 15 min, 1 hand 48 h after administration of diclofenac. The morphological changes caused by diclofenac probably represent decreased cell motility.

    The extent of surgical trauma, and especially detachment of periosteum, seems to be the factor eliciting HBF after THA by activation of endogenous factors. NSA!Ds probably act prophylactically against HBF by inhibiting the recruitment of fibroblasts and their subsequent proliferation stimulated by PDGF and other growth factors.

    NSAID treatment for two weeks after THA and avoidance, if possible, of trochanter osteotomy is recommended for prophylaxis against HBF.

    Back pain and spinal deformity: common among wheelchair users with spinal cord injuries1996Inngår i: Scandinavian Journal of Occupational Therapy, ISSN 1103-8128, E-ISSN 1651-2014, Vol. 3, nr 1, s. 28-32Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    During the past 15 years, wheelchair development has focused on driving properties. Back pain, however, is a problem among wheelchair users. Thirty-one wheelchair users, mean age 46 years (range 21–79), (3 women and 28 men), with spinal cord injuries were studied with regard to back pain and spinal deformity. Sixteen subjects had tetraplegia and 15 had paraplegia; median time since injury was 11 years (range 2–37). Pain was assessed using pain drawings, visual analogue scale and questionnaire. Spinal deformity was examined using X-ray, weight distribution, 3D magnetic motion tracker, photographs and physical examination. Some degree of back pain was found in 84% of the patients. Most patients could modify their pain by changing their sitting posture or by rest in bed, and had some kind of spinal deformity that might be related to neurological injury and sitting posture. Further wheelchair research considering the ergonomics of both driving and sitting seems important.

    Consequences of a change in rear-wheel position on seating ergonomics and mobility in spinal cord injured wheelchair usersManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    The aim of this study was to analyse the consequences of a change in rear-wheel position on mobility and seating ergonomic aspects. Twelve randomly selected paraplegic wheelchair users were tested iu two different activities, treadmill propulsion and computer work, in two different seating positions. The change in wheel position did affect chair ergonomics with respect to weight distribution and seat-inclination. These changes did have an effect on push frequency and stroke angle during treadmill, propulsion. We found no consistent effect on mechanical efficiency, estimated exertion, breathlessness or seating quality in this group. Nor did we find any consistent significant effect on pelvic position or under-seat pressure. There are effects from wheelchair adaptation, but these seem to be individual. With the knowledge of risk factors related to seating posture in mind, future research concerning effects of wheelchair adaptation has to be performed with considerations for individual changes.

    Early, controlled tension improves the material properties of healing human Achilles tendons after rupture: a randomized trial2013Manuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Background: Weight-bearing in a fixed brace after acute Achilles tendon rupture does not necessarily lead to mechanical tension in the tendon. Early motion has a positive effect on the clinical outcome, but it is not clear if this is due to effects on tendon strength or to unspecific effects. The aim of this study was to examine if tensional loading leads to improvement of the mechanical properties of the healing, human Achilles tendon.

    Hypothesis: The elastic modulus of the tendon callus is increased by early tensional loading.

    Study Design: Randomized controlled trial; level of evidence: 2.

    Methods: Thirty-five patients with an acute Achilles tendon rupture were recruited consecutively. They were operated with a single suture, and received metal markers in the distal and proximal part of the tendon. After surgery, patients were randomized to either cast immobilization for 7 weeks or tensional loading. The latter group wore a cast for 2 weeks, and then a removable foam walker boot for 5 weeks. They were instructed to remove the boot twice daily and push a special training pedal to produce a predetermined, gradually increasing tensional load on the healing tendon. At 7, 19 and 52 weeks postoperatively, patients were investigated with Roentgen Stereophotogrammetric Analysis (RSA) under different loading conditions, and computed tomography (CT). The collected data allowed calculation of modulus of elasticity. At 52 weeks, we also examined clinical outcome, using the Achilles tendon Total Rupture Score (ATRS) and a heel-raise index.

    Results: The elastic modulus at 19 and 52 weeks was higher in the tensional loading group. There was no significant difference in ATRS or heel-raise index at 52 weeks. As in previous studies, there was a significant correlation between the modulus at 7 weeks and the heel-raise index at 52 weeks. There was moderate tendon elongation.

    Conclusion: Early tensional loading improves the mechanical properties of the healing Achilles tendon.

    Autologous Platelets Have No Effect on the Healing of Human Achilles Tendon Ruptures A Randomized Single-Blind Study2011Inngår i: AMERICAN JOURNAL OF SPORTS MEDICINE, ISSN 0363-5465, Vol. 39, nr 1, s. 38-47Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Animal studies have shown that local application of platelet-rich plasma (PRP) stimulates tendon repair. Preliminary results from a retrospective case series have shown faster return to sports. Hypothesis: Autologous PRP stimulates healing of acute Achilles tendon ruptures. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Thirty patients were recruited consecutively. During surgery, tantalum beads were implanted in the Achilles tendon proximal and distal to the rupture. Before skin suture, randomization was performed, and 16 patients were injected with 10 mL PRP (10 times higher platelet concentration than peripheral blood) whereas 14 were not. With 3-dimensional radiographs (roentgen stereophotogrammetric analysis; RSA), the distance between the beads was measured at 7, 19, and 52 weeks while the patient resisted different dorsal flexion moments over the ankle joint, thereby estimating tendon strain per load. An estimate of elasticity modulus was calculated using callus dimensions from computed tomography. At 1 year, functional outcome was evaluated, including the heel raise index and Achilles Tendon Total Rupture Score. The primary effect variables were elasticity modulus at 7 weeks and heel raise index at 1 year. Results: The mechanical variables showed a large degree of variation between patients that could not be explained by measuring error. No significant group differences in elasticity modulus could be shown. There was no significant difference in heel raise index. The Achilles Tendon Total Rupture Score was lower in the PRP group, suggesting a detrimental effect. There was a correlation between the elasticity modulus at 7 and 19 weeks and the heel raise index at 52 weeks. Conclusion: The results suggest that PRP is not useful for treatment of Achilles tendon ruptures. The variation in elasticity modulus provides biologically relevant information, although it is unclear how early biomechanics is connected to late clinical results.

    Bisphosphonate Use and Atypical Fractures of the Femoral Shaft2011Inngår i: NEW ENGLAND JOURNAL OF MEDICINE, ISSN 0028-4793, Vol. 364, nr 18, s. 1728-1737Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND Studies show conflicting results regarding the possible excess risk of atypical fractures of the femoral shaft associated with bisphosphonate use. METHODS In Sweden, 12,777 women 55 years of age or older sustained a fracture of the femur in 2008. We reviewed radiographs of 1234 of the 1271 women who had a subtrochanteric or shaft fracture and identified 59 patients with atypical fractures. Data on medications and coexisting conditions were obtained from national registries. The relative and absolute risk of atypical fractures associated with bisphosphonate use was estimated by means of a nationwide cohort analysis. The 59 case patients were also compared with 263 control patients who had ordinary subtrochanteric or shaft fractures. RESULTS The age-adjusted relative risk of atypical fracture was 47.3 (95% confidence interval [CI], 25.6 to 87.3) in the cohort analysis. The increase in absolute risk was 5 cases per 10,000 patient-years (95% CI, 4 to 7). A total of 78% of the case patients and 10% of the controls had received bisphosphonates, corresponding to a multivariable-adjusted odds ratio of 33.3 (95% CI, 14.3 to 77.8). The risk was independent of coexisting conditions and of concurrent use of other drugs with known effects on bone. The duration of use influenced the risk (odds ratio per 100 daily doses, 1.3; 95% CI, 1.1 to 1.6). After drug withdrawal, the risk diminished by 70% per year since the last use (odds ratio, 0.28; 95% CI, 0.21 to 0.38). CONCLUSIONS These population-based nationwide analyses may be reassuring for patients who receive bisphosphonates. Although there was a high prevalence of current bisphosphonate use among patients with atypical fractures, the absolute risk was small.

    A pilot study describing a new device for the fixation of unstable trochanteric fractures of the hip1995Inngår i: International Journal of Orthopaedic Trauma, ISSN 0960-2941, Vol. 5, s. 69-71Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A new fixed 120o angled blade-plate with a buttress rod was used in a consecutive series of 27 trochanteric hip-fractures. Twenty fractures were classified as unstable. There were 20 women and seven men. The mean ages was 79 years (range:63-92). There were two intraoperative complications registered at surgery. All patients were allowed full weightbearing from the first day after surgery. Three patients dies and another four were not available for follow-up or were followed-up less than three months. Three cases were considered to be failures, The remaining 17 patients were followed-up at an avarage of 16 months. In these 17 patients, of which 12 were classified as unstable, the fractures healed with no change in position. In conclusion, we have found this new device to be a relatively simple method for the fixation of unstable trochanteric fractures. In addition, and of decisive importance, the mechanical properties seem to be sufficient for early full unaided weightbearing without risk of implant railure or non-union of the fractures.

    Complications and survival after surgical treatment of 214 metastatic lesions of the humerus2012Inngår i: Journal of shoulder and elbow surgery, ISSN 1058-2746, E-ISSN 1532-6500, Vol. 21, nr 8, s. 1049-1055Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: The humerus is the second most common long-bone site of metastatic bone disease. We report complications, risk factors for failure, and survival of a large series of patients operated on for skeletal metastases of the humerus. MATERIALS AND METHODS: This study was based on 208 patients treated surgically for 214 metastatic lesions of the humerus. Reconstructions were achieved by intramedullary nails in 148, endoprostheses in 35, plate fixation in 21, and by other methods in 10. RESULTS: The median age at surgery was 67 years (range, 29-87 years). Breast cancer was the primary tumor in 31%. The overall failure rate of the surgical reconstructions was 9%. The reoperation rate was 7% in the proximal humerus, 8% in the diaphysis, and 33% in the distal part of the bone. Among 36 operations involving an endoprosthesis, 2 were failures (6%) compared with 18 of 178 osteosynthetic devices (10%). In the osteosynthesis group, intramedullary nails failed in 7% and plate fixation failed in 22%. Multivariate Cox regression analysis showed that prostate cancer was associated with an increased risk of failure after surgery (hazard ratio, 7; P < 0.033). The cumulative survival after surgery was 40% (95% confidence interval [CI] 34-47) at 1 year, 21% (95% CI, 15-26) at 2 years, and 16% (95% CI, 12-19) at 3 years. CONCLUSIONS: Our method of choice is the cemented hemiprosthesis for pathologic proximal humeral fractures and interlocked intramedullary nail for lesions in the diaphysis. Pathologic fractures in the distal humerus are uncommon and associated with a very high reoperation rate.

    Advanced technology in the evaluation of chronic neck impairment1993Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    An electrogoniometrical method was modified for clinical motion analysis of the head and neck. Simultaneous measurements of neck motion range and motion pattern in the three planes could be obtained, and a graphical illustration of the movements was possible. The equipment showed high reliability and validity.

    Electrogoniometry was applied to female traverse crane operators with long-tenn absence from work due to neck complaints after several years' exposure to static occupational stresses. A reduced active neck motion range and motion speed consistent with the clinical picture of chronic trapezius myalgia was found, and a graphical illustration of the character of neck stiffness was obtainable. Due to large variations, the graphs did not allow any specific pathoaoatomic conclusions to be drawn.

    Electrogoniometry was further applied to fonner steelworks grinders with acquired work incapacity due to chronic neck complaints after long tenn exposure to vigorous upper body vibrations. A decreased active neck motion range and -motion speed was found. The motion pattern, as compared with that of the controls, was frequently altered. The curves showed a high degree of movement irregularities with large variations. Radiographically, the former grinders showed a moderately increased degree of degenerative cervical spine changes, without any certain relation to the obtained motion patterns. The grinders had a moderately decreased vibration sense in the upper and lower extremities. The results suggest an acceleration of the degenerative processes in the cervical spine, also involving the supporting soft tissues of the neck.

    In patients with suspected cervical vertigo body equilibrimn was examined with the head in predefined positions using combined electrogoniometry and dynamic posturography. Measurements with eyes closed on a sway-referenced forceplate showed a significantly increased body sway in the head position defined by the patients as the one most prone to elicit vertigo or unsteadiness. The difference occurred both when compared with neutral head position and when compared with the most painful head position in patients with neck pain only. An alteration of proprioceptiveafferents from the painful neck seemed to be the most likely cause.

    In patients with posttraumatic trapezius myalgia the microcirculation and electromyographic responses to local fatigue in the trapezius muscles were examined simultaneously using percutaneous laser-Doppler flowmetry and surface electromyography. At load levels causing local fatigue, an impaired ability to increase the blood flow was demonstrated on the painful side in patients with unilateral pain. In the 'normal' side an ordinary blood flow increase occurred at increased arm elevation angle, shoulder torque and EMG amplitude. A disturbed regulation of the trapezius muscle microcirculation should be considered in the evaluation of patients with posttraumatic chronic neck pain.

    Outcome after cup hemiarthroplasty in the rheumatoid shoulder: A retrospective evaluation of 39 patients followed for 2-6 years2000Inngår i: Acta Orthopaedica Scandinavica, ISSN 0001-6470, Vol. 71, nr 2, s. 180-184Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    33 rheumatoid patients, treated with hemispherical cup resurfacing hemiarthroplasty of the shoulder without medullary fixation (6 bilaterally), were reviewed after mean 4.4 (2-6) years. The median Constant score was 30 (15-79), mean proximal migration of the humerus 5.5 (SD 5.2) mm and mean glenoid erosion 2.6 (SD 1.7) mm. Proximal migration and glenoid erosion did not correlate with shoulder function or pain. Radiographic signs of loosening (changes in cup inclination combined with changes in cup distance above the greater tuberosity) occurred in one quarter of the shoulders. At follow-up, 26 patients were satisfied with the procedure, despite poor shoulder function and radiographic deterioration.

    Functional assessment system of lower-extremity dysfunction1996Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The Functional Assessment System (FAS) is a new instrument for evaluation of lower-extremity dysfunction. It consists of 20 variables, representing major lower--extremity functions related to daily life activities. The variables are divided into five groups: hip impairment, knee impairment, physical disability, social disability, and paiu variables. The grouping agrees fairly well with the WHO classification of impairment, disabilities and handicaps. Every variable is given a disability score on a five-point scale. The scores are plotted into a diagram, giving an individual functional profile. The profile can be used to document present functional status, for goal-setting, and for follow-up after treatment. It can also be used to design individual training programs.

    The aim of this thesis was:

    • to present the new Functional Assessment System (FAS)

    • to examine the metric properties of the FAS, and

    • to apply the FAS in some clinical situations.

    The FAS was applied on a series of patients with osteoarthritis of the hip or knee. Content validity was tested with factor analysis. The obtained factor structure agreed very well with the preliminary grouping of the variables. Concurrent validity was tested by comparison with measurements from the AIMS (Arthritis Impact Measurement Scales), the Rosser-Kind index (for evaluation of quality of life), and a radiographic scale for grading of osteoarthritis. There was a good agreement between the measurements of the FAS and the physical variables of the AIMS. There was also a good agreement between the FAS and the results obtained by the Rosser-Kind index. There was a low agreement between the FAS and the psychosocial variables of the AIMS. There was also a low correlation between the radiographic grading of osteoarthritis and the functional status recorded with the FAS. Inter-tester reliability was evaluated as correlation between the measurements performed by two independent physiotherapists. There was an almost perfect agreement between the two testers. The FAS was also tested for discriminatory power. It showed a good ability to differentiate between healthy subjects and patients with osteoarthritis. It also had a good power to discriminate between different degrees of the disease. The disability group of variables had better discriminstory power than the impairment group of variables. Most variables had a high specificity, whereas high sensitivity was mainly found in the disability group of variables and pain. The FAS was used to measure outcome after arthroplasty. A baseline functional status was recorded before surgery, and a goal profile was made. Six months later there was a striking improvement, especially in the disability variables and pain, and there was a high degree of goal achievement of most patients in most variables. Patients admitted for arthroplasty were examined for age-related diffirences in founctional status, Despite the fact that age was not included in the criteria for operation, old people had significantly lower functional status. This finding may indicate a hidden age criterion for referral of patients for arthroplasty. The age-related changes were mainly found in the disability group of variables. These findings may speak in favor of early surgery of patients with osteoarthritis.

    To summarize: The FAS had very good metric properties, such as validity, intertester reliability, discriminatory power, sensitivity and specificity. It was also a useful instrument in a clinical setting to record functional status, to set an individual treatment goal, and as an instrument for follow-up and outcome measurements. It was also sensitive in detecting age-related differences in patients admitted for arthroplasty. It can be used to communicate functional status to other health professionals, and to establish realistic goals for the patient.
