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. NO DISCLOSURES

A fracture of the tuberosity is associated with 16% of anterior glenohumeral dislocations. Manipulation of these injuries in the emergency department is safe with less than 1% risk of fracture propagation. However, there is a risk of associated neurological injury, recurrent instability and displacement of the greater tuberosity fragment. The risks and outcomes of these complications have not previously been reported. The purpose of this study was to establish the incidence and outcome of complications associated with this pattern of injury. We reviewed 339 consecutive glenohumeral dislocations with associated greater tuberosity fractures from a prospective trauma database. Documentation and radiographs were studied and the incidence of neurovascular compromise, greater tuberosity fragment migration and intervention and recurrent instability recorded. The mean age was 61 years (range, 18–96) with a female preponderance (140:199 male:female). At presentation 24% (n=78) patients had a nerve injury, with axillary nerve being most common (n=43, 55%). Of those patients with nerve injuries 15 (19%) did not resolve. Greater tuberosity displacement >5mm was observed in 36% (n=123) of patients with 40 undergoing acute surgery, the remainder did not due to comorbidities or patient choice. Persistent displacement after reduction accounted for 60 cases, later displacement within 6 weeks occurred in 63 patients. Recurrent instability occurred in 4 (1%) patients. Patient reported outcomes were poor with average EQ5D being 0.73, QDASH score of 16 and Oxford Shoulder Score of 41. Anterior glenohumeral dislocation with associated greater tuberosity fracture is common with poor long term patient reported outcomes. Our results demonstrate there is a high rate of neurological deficits at presentation with the majority resolving spontaneously. Recurrent instability is rare. Late tuberosity fragment displacement occurs in 18% of patients and regular follow-up for 6 weeks is recommended to detect this

Abstract. Introduction. There is little literature exploring clinical outcomes of secondarily displaced proximal humerus fractures. The aim of this study was to assess the rate of secondary displacement in undisplaced proximal humeral fractures (PHF) and their clinical outcomes. Methods. This was a retrospective cohort study of undisplaced PHFs at Royal Derby Hospital, UK, between January 2018-December 2019. Radiographs were reviewed for displacement and classified according to Neer's classification. Displacement was defined as translation of fracture fragments by greater than 1cm or 20° of angulation. Patients with pathological, periprosthetic, bilateral, fracture dislocations and head-split fractures were excluded along with those without adequate radiological follow-up. Results. In total, 681 patients were treated with PHFs within the study period and out of those 155 were excluded as above. There were 385 undisplaced PHFs with mean age 70 years (range, 21–97years) and female to male ratio of 3.3:1. There were 88 isolated greater tuberosity fractures, 182 comminuted PHFs and 115 surgical neck fractures. Secondary displacement occurred in 33 patients (8.6%). Mean time to displacement was 14.8 days (range, 5–45days) with surgical intervention required in only 5 patients. In those managed nonoperatively, three had malunion and one had nonunion. No significant differences were noted in ROM between undisplaced and secondarily displaced PHFs. Conclusion. Undisplaced fractures are the most common type of PHF. Rate of secondary displacement is low at 8.6% and can occur up to 7 weeks after injury. Displacement can lead to surgery, but those managed conservatively maintain their ROM at final follow up

Introduction. Surgical fixation of greater tuberosity fractures in the shoulder is the choice of treatment even if the fragment is minimally displaced. This helps to reduce the incidence of impingement secondary to a malunited tuberosity fragment especially in younger patients. We evaluated the functional outcome of our patients treated with open reduction and internal fixation of these fractures using cancellous screws. Materials and Methods. 19 patients with a mean age of 57.1 years (range 27–84) with 19 isolated greater tuberosity fractures treated with cancellous screws were included. These patients were evaluated after an average follow up period of nearly four years (range 66–444 weeks) using the DASH score and the Constant and Murley score. They were also clinically assessed to check for signs of impingement. Results. The median age in our study was 59. The mean Constant and Murley score was 75 (range 35–98) and the mean DASH score was 15.7 (0.8–45.0) which is a good result. Most patients had trouble in performing overhead activities (as per the DASH scoresheet) inspite of surgery. Impingement signs were also positive in nearly half of our patients (9 patients). Conclusions. Greater tuberosity fracture fixation using cancellous screws is a simple procedure associated with good results. However comparision needs to be made with the outcomes following fixation using suture anchors which is also a popular technique
