Study Summary

Seventy-six patients with traumatic anterior shoulder dislocation were randomized to receive Tang’s method (n=40) or the Hippocrates method (n=36). The primary outcome of interest was reduction success rate. Secondary outcomes included reduction time, pain (VAS) before/during/after reduction, and ASES scores at one, three, and six months. Outcomes were assessed up to six months. Overall, the results of the study revealed that Tang’s method achieved a 100% success rate vs 80.6% with Hippocrates and markedly shorter reduction time (≈71 s vs ≈412 s). Moreover, pain during and after reduction was lower and functional recovery (ASES) was superior at all follow-ups with Tang’s method. These findings suggest Tang’s method is a faster, less painful, and more effective reduction maneuver than the Hippocrates method for acute anterior shoulder dislocation.
