OBJECTIVE: The objective of this study was to conduct a comparative quantitative analysis of outcomes, radiographic findings, and magnetic resonance imaging results after laminectomy or laminotomy was performed for @entity1 with @entity2649 . Such as analysis had not previously been conducted. METHODS: Twenty-six @entity1 with no exclusion criteria who were treated surgically for acquired @entity850 at the Division of Neurological Surgery at The Ohio State University from 1990 to 1993 were studied retrospectively. At follow-up examinations, each @entity1 completed a detailed questionnaire that included visual analog scales, functional assessments, and the medical outcome study short form health survey, SF-36. Each @entity1 underwent plain static and dynamic radiography that detailed vertebral body sagittal listhesis and rotation and magnetic resonance imaging that evaluated dural sac compression. RESULTS: The mean follow-up duration was 36.7 months. Good outcome was defined by the presence of three criteria: no greater than mild @entity158 (Grades 0-4), the ability to walk more than one block without developing lower extremity @entity158 , and the ability to walk without assistance devices. Fifty-eight percent of the @entity1 who had undergone laminectomies and 50% of the @entity1 who had undergone laminotomies had good outcomes. All were judged to have had adequate decompression. The average maximum postoperative listhesis was 17.3 +/- 9.9% in the laminectomy group and 17.6 +/- 12.5% in the laminotomy group. In contrast to some previous studies, pre- or postoperative listhesis was not statistically related to outcome in either group. @entity1 in each poor outcome category seemed to have worse comorbid medical conditions than did @entity1 in the good outcome category. The SF-36 measurements of poor functioning because of health factors and bodily @entity158 correlated somewhat with poor outcomes in the @entity1 who had undergone laminectomies. In @entity1 who had undergone laminotomies, the only statistically significant finding among the outcome groups was the effect of poor emotional health on activity for the @entity1 with poor outcomes. CONCLUSION: This study indicates that laminotomy can adequately decompress @entity2649 , that laminectomy and laminotomy have the same degree of postoperative listhesis, and that the quantitative outcome of any treatment for @entity2649 is dependent not only on surgical factors but also on comorbid physical and psychological factors.
