Randomized Controlled Trial Comparative Study
Direct lateral approach to lumbar fusion is a biomechanically equivalent alternative to the anterior approach: an in vitro study.
A human cadaveric biomechanical study of lumbar mobility before and after fusion and with or without supplemental instrumentation for 5 instrumentation configurations. ⋯ Our data support that the direct lateral approach, when supplemented with bilateral PSF, is a minimally invasive and biomechanically stable alternative to the open, anterior approach to lumbar spine fusion.

Retrospective, radiographical analysis of mathe-matical formulas used to predict sagittal vertical axis (SVA) after pedicle subtraction osteotomy (PSO). ⋯ Preoperative planning for PSO is essential to optimize postoperative spinal alignment. Mathematical models that do not consider pelvic parameters and changes in unfused spinal segments poorly predict optimal postoperative alignment and may predispose to poor clinical outcomes. The Lafage formulas, which incorporated PT and spinal compensatory changes, best predicted optimal SVA.

Retrospective case series. ⋯ Long-term follow-up after surgery for meningiomas indicated that Simpson grade I resection should be selected whenever practicable when treating younger patients or dumbbell-type meningiomas. Tumors recurred at 12 years, on average, in approximately 30% of patients who underwent grade II resection.

Review Case Reports
Pediatric noncontiguous spinal injuries: the 15-year experience at a level 1 trauma center.
Retrospective review. ⋯ There is a high incidence of children with multiple NCSI who are more likely to experience neurological injuries compared with patients with single-level or contiguous spinal injuries. Patients with a single-level spinal injury on existing imaging with an associated neurological injury should undergo at least plain films of the entire spine to exclude noncontiguous injuries. In patients without neurological injury and a single spinal fracture, radiography showing at least 4 levels above and below the fracture should be performed. All children with spinal injury should have associated injuries carefully excluded.

The Roland-Morris Disability Questionnaire (RMDQ) was translated and then adapted and validated. ⋯ The SCRMDQ was reliable and valid as a low back pain measurement tool in patients with or without radicular leg pain in Mainland China. The further use and research with the questionnaire were recommended.
