Objective: This study investigates the impact of adjustable arm holders on ensuring stable fixation in the appropriate position and rotation during surgery, as well as on surgery duration and early postoperative functional outcomes in patients with proximal humerus fractures. Methods: A retrospective evaluation was conducted on 34 patients with Neer 3-part or 4-part proximal humerus fractures. They were divided into two groups: eighteen patients without an adjustable arm holder and 16 patients with an adjustable arm holder TRIMANO FORTIS® (Arthrex, Maquet GmbH) during surgery. Surgery times were obtained from patient files, and functional outcomes were assessed postoperatively using joint range of motion and Constant-Murley scores. Results: No significant difference in surgery duration was found based on the number of fracture parts (p=0.741). However, a significant difference was observed in postoperative Constant-Murley scores relative to the number of fracture parts (p=0.047), with 3-part fractures showing better functional recovery. The use of adjustable arm holders significantly reduced surgery time (p=0.003) and improved postoperative Constant-Murley scores (p=0.008). Increased surgery duration negatively impacted postoperative Constant-Murley scores (p=0.001). Regression analysis identified age, use of adjustable arm holders, and number of fracture parts as significant factors influencing postoperative Constant-Murley scores (p<0.0001), with age and number of fracture parts negatively affecting recovery, and the use of adjustable arm holders having a positive effect. Conclusion: Adjustable arm holders significantly reduce surgery duration and improve postoperative functional outcomes in patients with Neer 3-part and 4-part proximal humerus fractures. Superior functional recovery was noted in patients with 3-part fractures compared to those with 4-part fractures.
