The effect of frontal plane osteotomy angle on lateral cortex fracture in medial open wedge high tibial osteotomy procedure.

Background: Precise high tibial osteotomy is crucial, especially for middle-aged individuals with medial compartment arthritis, aiming to prevent complications like lateral cortex fractures. This study explores how frontal plane osteotomy inclination impacts lateral cortex fractures during medial open-wedge high tibial osteotomy.

Methods: Using finite element analysis, tibia models underwent osteotomies at angles of 10°, 13°, 16°, 19°, and 22°, forming five models.

Can the presence of SLAP-5 lesions be predicted by using the critical shoulder angle in traumatic anterior shoulder instability?

Objective: Although SLAP-5 lesions are associated with recurrent dislocations, their causes and pathomechanisms have not been fully elucidated. This study aimed to investigate the association between SLAP-5 lesions and scapular morphology in traumatic anterior shoulder instability (ASI). We hypothesized that there may be a relationship between SLAP-5 lesions and scapular morphology in traumatic ASI patients.
