Objectives: Locked fracture-dislocation of the proximal humerus (LFDPH) is a very severe complex injury; neither arthroplasty nor internal plating are fully satisfactory. This study aimed to evaluate different surgical treatments for LFDPH to determine the optimal option for patients of different ages.

Methods: From October 2012 to August 2020, patients who underwent open reduction and internal fixation (ORIF) or shoulder hemiarthroplasty (HSA) for LFDPH were retrospectively reviewed. At follow-up, radiologic evaluation was performed to evaluate bony union, joint congruence, screw cut-out, avascular necrosis of the humeral head, implant failure, impingement, heterotopic ossification, and tubercular displacement or resorption. Clinical evaluation comprised the Disability of the Arm, Shoulder, and Hand questionnaire and Constant-Murley and visual analog scale scores. Additionally, intraoperative and postoperative complications were assessed.

Results: Seventy patients (47 women and 23 men) with final evaluation results qualified for inclusion. Patients were divided into three groups: group A: patients aged under 60 years who underwent ORIF; group B: patients aged older than 60 years who underwent ORIF; and group C: patients who underwent HSA. At a mean follow-up of 42.6 ± 26.2 months, function indicators, namely shoulder flexion, and Constant-Murley and Disability of the Arm, Shoulder, and Hand questionnaire scores in group A were significantly better than those in groups B and C. In comparison, function indicators in group B were slightly but not significantly better compared with group C. Regarding operative time and visual analog scale scores, there were no significant differences between the three groups. The overall complication rate was 22.9% (16/70); specifically, complications occurred in 25%, 30.6%, and 10% of the patients in groups A, B, and C, respectively.

Conclusion: ORIF and HSA for LFDPH provided acceptable but not high results. For patients aged < 60 years, ORIF might be optimal, whereas, for patients aged older than 60 years, both ORIF and HSA provided similar results. However, ORIF was associated with a higher rate of complications.
