Outcome following fractures of the greater tuberosity of the humerus: a retrospective study

British Orthopaedic Association 2012 Annual Congress



Abstract

Background

The purpose of this retrospective study was to examine the functional outcomes of patients treated for isolated fracture of the greater tuberosity (GT) and to determine how their outcomes were affected by fracture pattern, treatment choices, associated shoulder injuries, the post fixation displacement of GT fragment and the time delay between injury and fixation.

Methods

Forty-eight (28 male and 20 female) patients (mean age 45 years) treated at our institution between 1999–2009 matched our inclusion criteria. Thirty-five patients were treated surgically and 13 conservatively. Functional outcome was assessed using Oxford scores (OS), University of California and Los Angeles (UCLA) rating scale and the shoulder index of the American Shoulder and Elbow surgeons (ASES). The outpatient follow up time required and the presence of other shoulder injuries, time delay to surgery and the time off work were also recorded.

Results

Outcome scores for patients who sustained simple vs comminuted fractures were not significantly different (OS = 41.8 vs 41, ASES 23.8 vs 23.4, UCLA 26.6 vs 26.3). Time taken off work was less in those who had a comminuted vs a simple fracture (21 vs 30 weeks). Shoulder dislocation was present in 77% and patients had a significantly worse outcome than those with no dislocation (OS = 40.6 vs 44, ASES 22.9 vs 26). Rotator cuff repair was required in 21% of patients and was also associated with a worse outcome (OS 42.8 vs 36.8, ASES 24.5 vs 20.5). Post fixation displacement of the GT fracture of < 5 mm led to a significantly better outcome than displacement >5mm (OS = 43 vs 37, ASES = 25.6 vs 17.7, UCLA 28.2 vs 21.3).

Conclusion

Isolated fractures of the greater tuberosity have a worse outcome if they are associated with shoulder dislocation, rotator cuff tear and post fixation displacement of >5mm.
