Management of Proximal Humerus Fracture With Concurrent Axillary Artery Injury Using a Saphenous Vein Graft and Reverse Shoulder Prosthesis: A Case Report.

This case report details the management of a 60-year-old male who sustained a complex proximal humerus fracture with an axillary artery injury following a fall. Initial assessment revealed a fractured humeral head and complete occlusion of the axillary artery, which was repaired using a saphenous vein graft. Subsequently, the patient underwent reverse shoulder arthroplasty (RTSA) after the limb stabilized. The staged approach, prioritizing urgent vascular repair followed by delayed orthopedic intervention, proved effective. The patient achieved satisfactory functional recovery with an improved range of motion and no pain. This case highlights the importance of prompt diagnosis and treatment of vascular injuries in complex proximal humeral fractures and supports the use of saphenous vein grafting and RTSA as effective management strategies.
