Multicenter Study Comparative Study
Scoliosis Research Society-Schwab adult spinal deformity classification: a validation study.
Inter- and intra-rater variability study. ⋯ Data from this study show that there is excellent inter- and intra-rater reliability and inter-rater agreement for curve type and each modifier. The high degree of reliability demonstrates that applying the classification system is easy and consistent.
-
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.
-
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.
-
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.
-
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.
