Abstrakt: Introduction: The purpose of this prospective study was to examine clinical results of tuberosity refixation in RSA for the treatment of displaced PHF in elderly patients. We hypothesized that tuberosity refixation would increase clinical outcome.
Methods: In this prospective study, 50 patients were included after receive a primary RSA for complex proximal humeral fracture between March 2013 and December 2015 for follow-up after three, 12 and 24 months. A functional and radiological assessment was performed on the patients.
Results: At final follow-up after a mean period of 25.1 months, data were available for 30 women and 6 men (74% of the included overall study collective) with a mean age of 77 years (range 55-93 years) at time of surgery. The tuberosities were refixated in 74% (n = 37) and in 26% (n = 13) resected. RSA with tuberosity refixation resulted in better clinical shoulder function compared to RSA with non-refixated tuberosities. The data show an external rotation with a significant difference (24.9° vs. 14°, p < 0.05) in favor of participants with refixation. The raw CMS was statistically significant (71.3 vs. 56.3, p < 0.05) after refixation, and SSV was significant improved (82.7% vs. 68%, p < 0.05) in the same group. Among 3 of 50 patients a total of 3 complications occurred with a total of 6% surgical revision.
Conclusions: In this prospective study, tuberosity refixation as part of fracture treatment using RSA results in better external rotation, subjective assessment of shoulder recovery (measured by SSV and by raw CMS) in elderly patients, compared with tuberosity excision.
