Morphometric and volumetric analyses and virtual screw placement. ⋯ Subaxial cervical unilateral translaminar screw placement is a potentially safe and effective technique to use in conjunction with preoperative CT scanning for all vertebral levels. The same is true for bilateral placement at C7 but not at C3-C6. A prospective study to evaluate the long-term outcomes of translaminar fixation at all vertebral levels is currently underway.

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 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.
