-
A retrospective observational study. ⋯ The results in this study indicated that traumatic CSF leak was not observed on CTM in patients with WAD, in whom CSF leak was suspected on RIC.
-
Retrospective review. ⋯ Dural ossification was the main reason for dural tears. In all, 78 of the 85 patients with CSF leakage or dural tear were successfully cured. The success rate was 91.8%, which indicated that a series of comprehensive treatments was an effective strategy to treat these patients.
-
Retrospective case series. ⋯ In this single-surgeon series, revision after the index spinal fusion was required for a relatively low proportion of patients. The main indications for revision were residual rib deformity, hook dislodgment, and progression of the unfused compensatory curve.
-
Prospective observational study. ⋯ Both minor and major complications were found to increase the cost of care in a prospective assessment of spine surgery complications. Specific patient comorbidities and perioperative complications are associated with significant increases in the total cost of care to society.

Comparative Study
In vivo topographic analysis of lumbar facet joint space width distribution in healthy and symptomatic subjects.
In vivo 3-dimensional facet joint space width measurement. ⋯ This in vivo study shows variations in facet joint space width narrowing with spinal level and region within the facet joint and in vivo evidence of localized, age-influenced facet cartilage thinning. Techniques developed in this study may be applied in the detection of early osteoarthritis-related changes in the facet joints.
