Abstract
Purpose
In the case of reverse shoulder arthroplasty (RSA) for proximal humeral fractures (PHFs) with tuberosity reconstruction, it is unclear whether the supraspinatus tendon continues to play a role. The aim of this study was to evaluate the clinical and radiological outcomes of RSA for PHFs in a large cohort of elderly patients and compare the results in the case of supraspinatus excision or preservation.
Methods
In this retrospective multicentre study, 150 patients (mean age 77 years, 93% female) were reviewed and radiographed with a minimum follow-up of 24 months. The same Grammont prosthetic design was used in all cases (inclination angle 155°, non-lateralised glenosphere). Patients were divided into two groups: Group A (n = 117) underwent supraspinatus excision and Group B supraspinatus preservation (n = 33). Complications were recorded, and shoulder function, active mobility and subjective results were assessed.
Results
At a mean follow-up of 59 months, there was no statistical difference in the complication rate (6% vs. 6.8%, p = 1), mean Constant score (61 points vs. 59 points, p = 0.52), simple shoulder value (74% vs. 73.9%, p = 0.9), active anterior elevation (125° vs. 128°, p = 0.45) and internal rotation (4.9 points vs. 4.1 points, p = 0.2). However, mean active external rotation was better in Group A (22° vs. 13°, p = 0.01). The greater tuberosity healing rate in satisfactory position did not differ statistically between the groups (68% vs. 55%, p = 0.14).
Conclusion
In the case of RSA with tuberosity reconstruction for acute PHFs, there is no clear evidence that supraspinatus preservation is advantageous.
