The interrater reliability of Modic changes among a potential basivertebral nerve ablation population: Why AC1 may be preferred to kappa.

Interrater reliability of Modic changes is subject to variables which affect consistency in reporting. Given the importance of Modic change identification for basivertebral nerve ablation (BVNA) candidacy, interrater reliability for this specific cohort has not yet been reported. Twenty lumbar magnetic resonance images of potential basivertebral nerve candidates were independently reviewed by two neuroradiologists and two interventional spine physiatrists for the presence and characterization of Modic changes.

Are Arthroplasty Procedures Really Better in the Treatment of Complex Proximal Humerus Fractures? A Comprehensive Meta-Analysis and Systematic Review.

Objective: A meta-analysis and systematic review was performed to compare outcomes of open reduction and internal fixation (ORIF), hemiarthroplasty (HA), and reverse total shoulder arthroplasty (rTSA) for complex proximal humerus fractures. Data sources: MEDLINE, Embase, and Cochrane Library databases were screened. Search terms included reverse total shoulder arthroplasty, open reduction internal fixation, hemiarthroplasty, and proximal humerus fracture.
