Abstract
Purpose of study
The outcomes of conservatively managed minimally displaced isolated greater tuberosity fractures are sparsely reported and the aim of this study was to look at the outcome of these fractures.
patients and methods
Twenty-seven patients who had sustained a greater tuberosity fracture were identified. They were all managed by a single surgeon. All patients had a regime of initial immobilisation for 3 weeks followed by physiotherapy and range of motion exercises. They were all x-rayed at 1 week and 3 weeks after injury to monitor for any displacement. Four fractures occurred with an anterior dislocation. In seven patients the fracture was not visible on x-ray but was diagnosed on Ultrasound or MRI. Twenty-three of 27 patients were available for follow-up. For this follow up, the patients were telephonically contacted and the Oxford Shoulder Score (OSS) was completed to assess their outcome.
Results
There were 12 males and 11 females in the review. The average age was 44 yrs (6–71 yrs) and the average follow up was 26.2 months (6–43 months). The OSS for the 23 patients ranged from 22–48 (average 44, median 47, mode of 48). Fourteen patients had LASI as part of their management after they started to develop pain and impingement symptoms. The ones with LASI had a slightly lower median OSS (46) compared to those without (48) but the modal scores were the same (48). One patient needed surgery after the initial fracture displaced at 3 weeks while another patient needed an acromioplasty at 10 months for impingement. Three patients developed a frozen shoulder but subsequently settled and had excellent outcome scores.
Summary
In this study, 30% (7) of the fractures were not visible on the x-rays but diagnosed on ultrasound or MRI. Nearly half the patients required subacromial steroid injections to improve recovery. In only one patient did the fracture displace and require fixation.
Conclusion
Conservative management of minimally displaced greater tuberosity fractures yields good functional results though a high percentage of patients require subacromial steroid injections. Secondary displacement is rare, however close vigilance of fracture is advised with x-rays done at 1 and 3 weeks postoperatively.
