EP.FRI.34 Audit of management of shoulder dislocations against BOA Traumatic anterior shoulder instability Guidelines

Background Traumatic anterior shoulder dislocation is associated with a high risk of shoulder instability, reduced functional outcome, and recurrence. We conducted an audit to assess the direct management, review in fracture clinic, and definitive imaging of patients with anterior shoulder instability in Southport and Formby Hospital. Aim To identify compliance with the 2015 BOA Traumatic anterior shoulder instability guidelines. Method Identified all patients from 01/01/2019 to 31/12/2019 who had shoulder dislocation coded for their diagnosis. We used imaging, scanned notes, and clinic letters where available to identify the clinical information. We excluded patients with a false diagnosis code, and those with non-local post codes from the analysis. Results We identified 67 patients who had an anterior dislocation. 88% of patients had x-rays in both AP and Lateral. We identified that 8.9% of patients had pre-reduction x-rays in AP only, 11.9% had no pre-reduction x-rays, and 1.5 % had no post reduction imaging. 79% of patients were seen in clinic within 6 weeks but only 40.3% were seen by a shoulder specialist and only 43.3% had appropriate imaging. 16.4% of patients were not given fracture clinic follow up. Conclusion Although most patients were managed acutely according to the guidelines, the follow up and subsequent investigations of these patients can be improved. One method we suggest is renaming fracture clinic days from consultant names to sub-specialty clinic names. In addition, a dedicated session to review the guideline with senior orthopedic surgeons cold improve the compliance as well.

Labral lesions in first-time traumatic anterior shoulder dislocation: it’s more than just Bankart …

Introduction Traumatic anterior shoulder dislocation occurs frequently and usually affects young, active male patients. Detachment of the anteroinferior labrum, known as the Bankart lesion, is a common result. However, more extensive entities including bony lesions and disruptions of the labral ring can also be found. The aim of the present work was to analyze all cases of first-time traumatic anterior shoulder dislocation at a level‑1 trauma center with regard to the type of labral lesion. Focus was placed on the frequency and distribution of complex lesions and the extent of the surgical repair. Patients and methods The clinical database of a level‑1 trauma center with a specialized shoulder unit was searched to identify all patients with first-time anterior shoulder dislocation treated between 2015 and 2019. Of 224 patients, 110 underwent primary surgical repair after first-time dislocation (mean age 40 years). Results A total of 62% of patients had only a soft tissue injury, while 38% (n = 40) showed a bony Bankart lesion/fracture of the glenoid fossa with a mean defect size of 26%. In only 31% of patients (n = 34), a classic Bankart repair was performed, whereas the remaining 69% underwent additional procedures. Conclusion In this series of surgically treated first-time traumatic anterior shoulder dislocations, the majority of cases presented with more complex lesions than an isolated classic Bankart lesion. The risk for bony involvement and associated pathologies, such as cuff tears and greater tuberosity fracture, increases with age and requires a more extensive surgical approach. Disruption of the labral ring was frequently found in both soft tissue and bony lesions and directly affected the surgical procedure.

Conservative management of first-time traumatic anterior shoulder dislocation

Traumatic anterior shoulder dislocation is a common injury in young and active patients and the proper treatment is still a matter of debate. The recurrence rate after conservative management remains high and, therefore, primary surgical intervention is sometimes recommended in very young patients whose risk of recurrences is highest. Immobilization in external rotation, first described by Itoi, is a promising conservative option as it provides adequate labral reduction and low recurrence rates. Recent meta-analyzes could not unequivocally demonstrate its superiority over internal rotation immobilization. However, biomechanical and early clinical results show a better effect on reduction of the labrum and lower recurrence rates for immobilization in a combination of abduction/external rotation than for external rotation alone. The present article aims to provide an overview of the conservative management of first-time traumatic shoulder dislocation in order to provide the treating physician or surgeon with the best current evidence as a basis for developing the appropriate treatment strategy for the patient.
