Most of the outcome question naires had a mixed content reflecting various constructs such as pain and symptoms , sleep disturbances , psychological dysfunctions , physical impairments , and social functions .
STUDY DESIGN A systematic literature review of outcome question naires design ed for assessing functional status or disability in patients with low back pain .
OBJECTIVES To provide a comprehensive overview of all functioning/disability question naires used in recent years and to explore how the main concept(s ) was described or defined in the original paper , the content or the domains of disability , and the measurement properties of the question naires .
SUMMARY OF BACKGROUND DATA A number of clinical tools design ed for evaluating the functional status of patients with low back pain have been developed .
Only a few have been review ed earlier , and there has been little focus on the content reflected in the question naires .
Standardized evaluation of long-term results after anterior lumbar interbody fusion
A total of 113 patients , excluding those with tumor , spondylitis , and idiopathic scoliosis , underwent anterior lumbar interbody fusion ( ALIF ) with autologous iliac crest graft between 1984 and 1991 at our department . The proportion of these who were failed back patients was higher than that reported in the literature . Evaluation of functional outcome was feasible in 80 patients , utilizing Oswestry and Marburg scores , which were closely intercorrelated . The overall results yielded an improvement in the Oswestry score of 35.7 percentage points . A subset of 52 patients who were evaluated twice , showed the same results at an average of 6.6 years as they did at 2.3 years following surgery . Functional results showed a weak correlation with postoperative height loss of the intervertebral space . Influencing factors for the functional result were : postoperative compensation cl aim , age , and obesity . Of the professional people involved , 19.4 % did not return to any occupation . Patients satisfied with the result had significantly greater functional improvement . Younger patients with additional dorsal distraction prior to ALIF for reduction of severe spondylolisthesis fared better than patients with ALIF alone . The rate of complications was low and did not contribute to the postoperative functional result . On the basis of these results further prospect i ve studies have been design ed and are currently underway
