Could direct transdeltoid approach to severely displaced proximal humerus fracture be advantageous for a better reduction?

Surgical treatment of proximal humeral fractures (PHF) is a challenge for orthopaedic surgeons. Despite the wide application of open reduction and internal fixation with locking plates, the optimal surgical approach of PHF is still debated. This study aims to evaluate the radiological outcomes, defined as anatomical restoration of the greater tuberosity and humeral head-shaft angle, of the deltopectoral (DPA) and the lateral transdeltoid (LTA) approaches in three- and four-part PHF, treated with locking plate.
