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.

Percutaneous radiofrequency facet joint denervation with monitoring of compound muscle action potential of the multifidus muscle group for treating chronic low back pain: a preliminary report.
A retrospective review. ⋯ Our results suggest that percutaneous radiofrequency facet joint denervation with CMAPs monitoring is a safe, long-lasting, and effective treatment for chronic facet joint pain. CMAP monitoring may be useful as an objective index for facet denervation.

Randomized Controlled Trial Multicenter StudyA pilot evaluation of the role of bracing in stable thoracolumbar burst fractures without neurological deficit.
Prospective, 2-center, observer-blinded, randomized controlled trial. ⋯ Neurologically intact patients with stable thoracolumbar burst fractures treated with or without bracing had similar radiographic and clinical outcomes at 6 months follow-up. The no-brace group had shorter in-hospital lengths of stay. Conservative therapy involving early mobilization without brace immobilization may be warranted. Further studies with a larger series of patients and longer follow-up are required for conclusive findings.

Clinical TrialIncidence of lumbar spine pedicle breach after percutaneous screw fixation: a radiographic evaluation of 601 screws in 151 patients.
Prospective clinical study. ⋯ Percutaneous pedicle screw fixation in the lumbar spine continues to be a technique embraced by modern spinal surgeons. The use of intraoperative fluoroscopic guidance is both a clinically safe and accurate method for instrumentation and is of comparable accuracy to other techniques. Although trajectory errors may occur, they are of rare clinical significance.

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.
