Abstract

By reviewing our institution's experience and relevant current literature, this study aims to evaluate the functional outcome of proximal humerus fracture parts 2 and 3 following surgical treatment of unstable or displaced proximal humeral fractures with the proximal humerus nail. Objective: To evaluate the functional outcomes of proximal humerus fractures of NEER classification part-2, part 3, managed by internal fixation with the intramedullary proximal humerus nail on the basis of Constant-Murley scores (CMS). Methods: Twenty-three patients with proximal humeral fractures were surgically treated with the proximal humeral nail. Neer's classification was used to classify the fractures. Patient demographics, mechanism of injury, duration of surgery, time to healing, and any complications were recorded. The Constant Shoulder Score was used to evaluate the functional outcome. In addition, a literature review was performed to evaluate overall healing and complication rates. Results: The mean age was 51.10 years, and the female-to-male ratio was 1.88:1. A total of 65.2% of injuries were due to a fall on level ground. A total of 69.56% of patients had NEER part 2 and 30.44% of patients had NEER part 3. The percentages of excellent, good, fair, and poor outcomes were 18%, 54%, 18%, and 9%, respectively. The percentage of excellent/good outcomes was 75% for NEER Part 2 and 66.6% for NEER Part 3. The percentages of superficial skin infection, rotator cuff stiffness, screw out (late), and screw impingement complication were 4.5%, 4.5%, 9.0%, and 4.5%, respectively
