The external rotation immobilisation does not reduce recurrence rates or improve quality of life after primary anterior shoulder dislocation: A systematic review and meta-analysis

Based on the results of our analysis, the ER immobilisation could not reduce the rates of recurrence after primary anterior shoulder dislocation or improve the quality of life compared with the IR immobilisation. More rigorous and adequately powered prospective randomised controlled trials with long-term follow-ups are required to elucidate a more objective outcome.
