Clinical and patient-reported outcomes after anterior cervical decompression and fusion surgery: A focus on functioning and daily life
2015 (English)Doctoral thesis, comprehensive summary (Other academic)
Anterior cervical decompression and fusion (ACDF), with or without an intervertebral cage to add support to the fused segment, is an established surgical treatment of cervical radiculopathy due to cervical disc disease. High recovery rates and pain reductions after surgery have been reported, with similar results with or without a cage. A few small studies have evaluated neck-related physical function and patient-reported disability with less promising results. No previous studies have evaluated clinical and patientreported measures of functioning or compared the Cloward Procedure with the Cervical Intervertebral Fusion Cage (CIFC) more than 10 year after surgery. No studies have explored the patients’ perspective on surgical outcome Knowledge on long-term functioning may provide a base for improved postoperative care and rehabilitation. Combining the perspectives of clinicians and patients may provide a better understanding of outcome after ACDF surgery than has previously been reported.
The overall aim of the thesis was to evaluate long-term functioning after anterior cervical decompression and fusion surgery due to cervical disc disease, and to provide new insights into patients’ experiences of daily life after surgery.
The more than 10-year patient-reported outcomes of pain, disability and psychosocial factors (n=77), as well as clinical outcomes of neck-related physical function (n=51) were evaluated and compared between the Cloward Procedure and the CIFC. Preoperative and surgery-related factors of importance for a good outcome in neck-related pain and disability at 10-year follow-up were also identified. Fourteen women were interviewed at 1.5 to 3 years after ACDF to explore their experiences of daily life.
There were no differences between the surgical techniques in long-term neck-related pain or patient-reported disability. Secondary outcomes were, with a few exceptions, similar between groups. Neck-related pain decreased after surgery and remained improved from the 2-year to the 10-year follow-up. However, disability ratings remained improved only in the CIFC group. Predictors of a successful outcome in neck-related pain intensity were high preoperative neck-related pain intensity (Odds Ratio 1.06) and nonsmoking (Odds Ratio 3.03). Male gender was the only predictive factor of a successful outcome in neck-related disability (Odds Ratio 4.33). Moderate to severe pain and patient-reported disability were seen in half of the participants at the 10-year follow-up, and neck-related physical impairments were seen in between 18% (cervical flexion) and 82% (neck-muscle endurance) of participants. Daily life was experienced as recovered or improved by women after ACDF surgery. However they were at the same time affected and limited by remaining symptoms. Behaviors and activities were altered to adjust to the symptoms. Social support provided by family, social and occupational networks, and by healthcare professionals were experienced as important in a good daily life.
In conclusion: long-term pain, physical function and patient-reported disability were similar between the two ACDF techniques. High preoperative pain intensity, non-smoking and male gender predicted a good long-term outcome. Individuals after ACDF surgery experienced improvements in pain intensity and a good effect of surgery although they simultaneously reported residual or recurrent disability.
