%X <B>BACKGROUND: </B>The risk of avascular necrosis, nonunion, or malunion is high in osteoporosis-related 4-part fractures. We evaluated the results of patients who underwent plate osteosynthesis with a vascularized pectoralis major graft compared with tricortical iliac grafting to treat 4-part proximal humerus fractures.<BR><B>METHODS: </B>Thirty-four patients aged 50-75 years with Neer 4-part proximal humerus fractures were studied. Group A (n = 17) underwent osteotomy of a 2.5 ± 1 cm pectoralis major pedicle bone graft and plate application, whereas group B (n = 17) underwent plate osteosynthesis using iliac autogenous grafts. Final follow-up assessments included evaluation using Constant and American Shoulder and Elbow Surgeons scoring systems, humeral neck-shaft angle (HNSA), humeral head height, and humeral head avascular necrosis.<BR><B>RESULTS: </B>Reduction loss was observed in 3 patients (17.6%) in group A, whereas it was observed in 10 patients (58.8%) in group B (P = .013). Humeral head avascular necrosis was found in 1 patient (5.8%) in group A, whereas it was found in 5 patients (29.4%) in the other group (P = .071). The HNSA was normal in 12 (70.5%) of group A patients, whereas it was normal in 6 (35.2%) of group B patients. The HNSA was weak or bad (<1200) in 29.4% of group A patients, whereas this rate was 64.7% in group B patients. Humeral head height was 2.64 ± 1.45 mm in group A and 3.66 ± 1.65 mm in group B. There were no statistically significant differences between the 2 groups in terms of Constant and American Shoulder and Elbow Surgeons scoring systems.<BR><B>CONCLUSIONS: </B>Pectoralis major bone pedicle graft in Neer 4-part proximal humerus fractures reduces the risk of avascular necrosis and nonunion rates. Our technique yielded excellent clinical and radiological results. We achieved recovery without creating additional donor site morbidity.
