Abstract

Background: Proximal humerus fracture treatment varies by surgeon preference and patient factors. This study compares patient and fracture characteristics, with outcomes between current surgical treatment options.

Methods: Between 1999 and 2018, 425 proximal humerus fractures underwent acute surgical management: open reduction internal fixation (ORIF, n = 211), hemiarthroplasty (HA, n = 108), or reverse shoulder arthroplasty (RSA, n = 106). Patient and fracture characteristics included age, American Society of Anesthesiologists physical status classification (ASA), and fracture classification. Postoperative motion at 3, 6, and minimum 12 months (avg 20 ± 21 months), radiographic outcomes, and postoperative falls were analyzed.

Results: Average age for treatment groups was 65 ± 13 years (range: 18-93 years). Fractures were classified as 2- (11%), 3- (41%), or 4-part (48%). Age, ASA, and fracture classification were associated with selected surgical management (P < .0001, =.001, <.0001, respectively). Outcomes showed a significant improvement in forward flexion from 3 months to 6 months in all groups (P < .0001). No difference in final motion was seen between groups. Radiographic union was higher in ORIF (89%), and similar between HA (79%) and RSA (77%, P = .005). Rate of reoperation was RSA 6.6%, ORIF 17.5%, and hemiarthroplasty 15.7% (P = .029). Postoperatively, 23% patients had at least 1 fall, of which 73% resulted in fractures.

Conclusion: Older patients with high ASA were treated with arthroplasty, and younger patients with lower ASA were treated with ORIF. All groups showed improvements in motion. At minimum 1 year of follow-up, there was no difference in motion between groups. ORIF and HA showed significantly more reoperations compared with RSA. Patients should be counseled about reoperation, fall risk, and prevention.
