Abstract
PURPOSE
The purpose of this study is to evaluate the relationship between trochlear medial facet osteophyte (TMFO) and elbow flexion in the elbow joints without trauma history. MATERIALS AND METHODS: Twenty five patients, who underwent computed tomography without elbow trauma history, were reviewed. Patients were checked for osteophyte or loose bodies in the coronoid and olecranon sides. The height and length of TMFO were measured.
RESULTS
The average elbow flexion contracture was 18.6degrees, and further flexion was 112.1degrees. The TMFO height and length was 2.2 mm and 4.7 mm, respectively. The average elbow further flexion was 105.1degrees in the coronoid block group (n=14) and 119.1degrees (p=0.011) in the coronoid free group (n=11). The relationship between further elbow flexion and TMFO was significant with a partial correlation coefficient of 0.687 (p<0.000) in the TMFO length.
CONCLUSION
Elbow joints with longer TMFO length decrease further flexion.
