Do knee alignment patterns differ between Middle Eastern and East Asian populations? A propensity-matched analysis using artificial intelligence.

Introduction: Population-based differences in knee alignment patterns may impact osteoarthritis (OA) progression. This study compares lower extremity alignment in knee OA between Middle Eastern (UAE) and East Asian (South Korean) populations using artificial intelligence (AI)-assisted analysis.

Methods: A retrospective review included patients with knee symptoms from South Korea (2009-2019) and the United Arab Emirates (UAE) (2015-2024).

Outcomes of radialization for radial longitudinal deficiency: 20 limbs with minimum 5-year follow-up.

We report functional and cosmetic outcomes in 14 patients (six bilateral and eight unilateral) with type IV radial longitudinal deficiency who underwent radialization. Follow-up ranged from 5 to 19 years. Outcome measures were grip and pinch strengths, Percival and Sykes score, Vilkki score, Cattaneo grading, and a questionnaire to patients.

Ancient Schwannoma of Radial Nerve: A Report of Two Cases.

Ancient schwannoma is a rare variant of schwannoma associated with a longstanding course. They differ from classical schwannomas in the long duration for this subtype of schwannoma to develop and also by demonstrating haemorrhagic and degenerative changes with nuclear atypia. It is because of these histologic hallmarks that they are frequently misdiagnosed as malignant tumours.
