Description of intervention(s) / exposure
Two interventions will be compared. Group A will receive external rotation bracing (using a Don Joy external Rotation Brace) full time for 6 weeks + routine post immobilization physical therapy. Group B will receive arthroscopic stabilisation surgery (approximately 90-180 minutes) + routine post operative physical therapy.

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be identified by clinical staff at participating hospital Emergency Departments. Patients meeting inclusion criteria who provide informed consent for participation in the study will be allocated the next participant identification number. The member of the research team coordinating intervention administration will then open an opaque envelope concealing the random allocation for that participant identification number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A member of the research team not involved in participant recruitment, assessments or intervention delivery will generate a random number sequence using a computerized random number generator. The randomization sequence will be concealed in opaque envelopes numbered in ascending order to correspond with participant identification numbers. Group allocation for each identification number will remain concealed in an opaque envelope until group allocation occurs.

Brief summary
The purpose of the study is to determine the clinical outcomes and effectiveness of two randomly allocated treatments used to manage acute anterior shoulder dislocations: six weeks of external rotation bracing versus early arthroscopic shoulder stabilisation intervention.

It is hypothesised that the arthroscopic shoulder stabilisation surgery may lead to better patient outcomes compared with the external rotation bracing on the basis that evidence for external rotation bracing is still emerging and (although promising) has not yet been established with as much rigor as arthroscopic shoulder stabilisation surgery. However, in the absence of substantial differences in patient outcomes, external rotation bracing may be demonstrated to be more cost-effective than surgery.

Outcomes from this study will inform clinical decision making about management for young people with shoulder dislocation. This study will not only impact clinical practice for this high demand patient group in Queensland, but nationally and internationally due to widespread uncertainty to the effectiveness (and cost-effectiveness) of the (cheaper and more conservative) external rotation bracing in comparison to arthroscopic shoulder stabilisation surgery amongst young patients (16-30 years) who have dislocated their shoulder for the first time.
