Dr. Archit Agarwal, a leading Consultant Joint Replacement Surgeon in Dehradun, successfully managed a rare and challenging case of Locked Posterior Shoulder Dislocation (LPSD) complicated by a reverse Hill-Sachs lesion (an anteromedial humeral head impression fracture). This condition, often missed in initial examinations, was secondary to an electric shock injury and proved resistant to closed reduction. Utilizing a pioneering surgical approach, Dr. Agarwal performed an open reduction and reconstructed the humeral head using a G graft block—a specialized hydroxyapatite and collagen composite—fixed with cannulated cancellous screws and PHILOS plate support. This novel technique effectively restored the articular sphericity of the humeral head while avoiding the donor-site morbidity associated with traditional autologous grafts. The patient achieved a full range of motion and excellent joint stability, with a successful 3-year follow-up confirming the long-term efficacy and regenerative potential of this advanced reconstructive method.
