Multicenter StudyPatterns of shoulder imbalance in adolescent idiopathic scoliosis: a retrospective observational study.
Retrospective cohort study. ⋯ Preoperative shoulder levels in AIS may be concordant with the T1 or discordant-each can have left or right shoulder elevation or balanced shoulders. Further, the shoulder might be MT dependent or PT dependent. Theoretically therefore, surgical balancing of the shoulder and upper instrumented vertebra placement should not depend only on the magnitude and stiffness of the PT curve.

Comparative StudyDoes prone repositioning before posterior fixation produce greater lordosis in lateral lumbar interbody fusion (LLIF)?
Retrospective comparative radiographic review. ⋯ In LLIF procedures, the largest increase in operative level segmental lordosis is brought about by cage insertion. Further lordosis may be gained by placing posterior fixation, including compressive maneuvers. Prone repositioning after cage placement does not produce any incremental lordosis change. Therefore, posterior fixation may be performed in the lateral position without compromising operative level sagittal alignment.

Long-term outcomes after revision neural decompression and fusion for same-level recurrent lumbar stenosis: defining the effectiveness of surgery.
Single-cohort study of patients undergoing revision neural decompression and fusion for same-level recurrent lumbar stenosis. ⋯ Our study suggests that revision neural decompression and instrumented fusion for recurrent same-level stenosis provides significant improvement in all patient-assessed outcome metrics and should be offered as a viable treatment option.

Comparative StudySingle-stage internal fixation for thoracolumbar spinal tuberculosis using 4 different surgical approaches.
A retrospective study was conducted on 148 spinal tuberculosis (TB) patients (M:F, 92:56; mean age, 39.7±12.3; range, 16-74 y) treated with anterior debridement and bone graft fusion with nail and screw internal fixation (nails+screws group); posterior pedicle screw fixation (pedicle screw group); vertebral arch pedicle internal fixation through a posterior route (posterior arch fixation group); or posterior debridement, bone graft fusion, and vertebral arch pedicle internal fixation (arch fixation group). ⋯ Surgical approach limitations and advantages should be considered based on the position and severity of spinal TB infection to maximize functional outcomes and minimize surgical risks.

Learning curve of a complex surgical technique: minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).
Prospective cohort study. ⋯ In our study, technical proficiency in MIS TLIF was achieved after 44 surgeries, and the latter patients benefited from shorter operative duration and radiation, less pain, and more relief in their back, leg, and neurogenic symptoms.
