ABSTRACT
Objective: To determine the results and factors affecting the outcome of open shoulder stabilisation.
Study design: Retrospective review.
Place and Duration of study: Department of Orthopaedics and Traumatology, Mid-Western Regional Hospital Ireland, from 1999 to 2006.
Methodology: We retrospectively reviewed shoulder instability patients with either anterior, antero-inferior or multidirectional shoulder instability treated with open Bankart repair with a minimum of 2-year follow-up. A thorough chart review was performed and patients were evaluated according to the Oxford Instability Score [OIS], the level of sport returned to, the influence of preoperative physiotherapy and the frequency of re-dislocation.
Results: Of the 136 identified patients, 108 [79%] responded to the questionnaire. Of the responders, there were 95 males and 13 females. The average age was 24 year [range 14-72 year]. Ninety-one patients had confirmed dislocation whereas 17 suffered from subluxation. The average time to surgery from the index instability incident ranged from 3 months to 10 years. The average OIS was 23, which correspond to a good result. There was no significance found in the OIS in relation to the age of the patient or pre-operative physiotherapy. Significant association with a better outcome included delay to surgery greater than 12 months and the absence of multidirectional instability. Of those who actively participated in sport, the return to the same was better in non-contact sport.
Conclusions: Open Bankart repair with and without capsulorrhaphy remained the gold standard for treatment of patients with shoulder instability. Rate of success, in terms of re-dislocation, was equivalent to international norms. It was found that a delay to surgery may be associated with a better outcome
