Abstract:

Objective　To find the optimal anchor points of anterior bundle isometric reconstruction of the elbow ulnar collateral ligament through anatomic study.　Methods　3 anchor points were marked near both proximal and distal ends of the anterior bundle of the elbow ulnar collateral ligament on 8 intact human adult elbow specimens. The distance variation was measured in each pair of points on both sides while flexing the elbow from 0 degree to 120 degree and was analysed statistically.　Results　Distance variation of the pair from the elbow rotation center on the humeral medial epicondyle to ulnar subcoronoid tubercle was minimal (P<0.0001). When proximal points were fixed on elbow rotation center, the distance variation was significantly less than the other 2 proximal points with significant difference (P<0.0001).　Conclusion　The optimal anchor points of the anterior bundle isometric reconstruction of the elbow ulnar collateral ligament is elbow rotation center on the humeral medial epicondyle and ulnar subcoronoid tubercle;
