    Abstract Background Lumbar spine fusion (LSF) effectively decreases pain and disability in specific spinal disorders; however, the disability rate following surgery remains high. This, combined with the fact that in Western countries the number of LSF surgeries is increasing rapidly it is important to develop rehabilitation interventions that improve outcomes. Methods/design In the present RCT-study we aim to assess the effectiveness of a combined back-specific and aerobic exercise intervention for patients after LSF surgery. One hundred patients will be randomly allocated to a 12-month exercise intervention arm or a usual care arm. The exercise intervention will start three months after surgery and consist of six individual guidance sessions with a physiotherapist and a home-based exercise program. The primary outcome measures are low back pain, lower extremity pain, disability and quality of life. Secondary outcomes are back function and kinesiophobia. Exercise adherence will also be evaluated. The outcome measurements will be assessed at baseline (3 months postoperatively), at the end of the exercise intervention period (15 months postoperatively), and after a 1-year follow-up. Discussion The present RCT will evaluate the effectiveness of a long-term rehabilitation program after LSF. To our knowledge this will be the first study to evaluate a combination of strength training, control of the neutral lumbar spine position and aerobic training principles in rehabilitation after LSF.

    The prevalence of depressive symptoms before and after surgery and its association with disability in patients undergoing lumbar spinal fusion

    PURPOSE: The aim of this study was to evaluate the prevalence of depressive symptoms and disability pre-operatively, at 3 months and at 1 year after lumbar spine fusion surgery. METHODS: Data was extracted from a dedicated lumbar spine fusion register, giving 232 patients (mean age 62 years, 158 females) who had undergone instrumented lumbar spine fusion. The frequency of depressive symptoms and disability was evaluated using the Depression Scale (DEPS) and Oswestry Disability Index (ODI). RESULTS: Depressive symptoms were found in 34, 13, and 15 % of the patients pre-operatively, at 3 months and at 1 year after surgery, respectively. The mean DEPS score decreased from 16.2 to 8.6 (p < 0.001) in patients who had depressive symptoms pre-operatively, and from 6.1 to 3.8 (p < 0.001) in those patients without pre-operative depressive symptoms. The mean ODI values pre-operatively, at 3 months and at 1 year after surgery were 53, 30, and 23, respectively, in patients with pre-operative depressive symptoms and 41, 23, and 20 in those patients without pre-operative depressive symptoms. The differences between the groups were statistically significant at all time points (p < 0.001). CONCLUSIONS: One-third of our patients with chronic back pain undergoing spinal fusion had depressive symptoms pre-operatively. The prevalence of depressive symptoms decreased after surgery. Although disability remained higher in those patients who had reported depressive symptoms pre-operatively, disability did decrease significantly in both groups post-operatively. Thus, there is no need to exclude depressive patients from operation, but screening measures and appropriate treatment practises throughout both pre-operative and post-operative periods are encouraged

    Biomechanical properties of absorbable implants in finger fractures

    The mechanical rigidity of five different methods of pin fixation in two proximal phalangeal fracture models was studied and absorbable implants were compared with metallic implants in a biomechanical cadaver study. Thirty phalanges were tested in apex palmar bending, compression and torsion. Results showed that rigidity of absorbable implants was comparable with metallic implants, except in torsion. © 1997 The British Society for Surgery of the Hand.link_to_subscribed_fulltex
