Study type
Interventional
Description of intervention(s) / exposure
This study will be conducted in a metropolitan emergency department in Sydney, NSW, Australia. The study will compare three methods of shoulder relocation that utilise different patient positioning and biomechanics to relocate the shoulder. An abduction and an adduction method will be compared with the chair method that utilises traction. The intervention with be performed by Emergency Department Nurse Practitioners, Physiotherapists and Medical Officers in the Fast track zone of the emergency department. Prior to commencement of the study each participating clinician will have face to face training to ensure the each method is performed according to the following descriptions.

Chair method (Traction)
The Chair Method is a traction technique that uses the back of a chair as a fulcrum whilst the clinician applies traction to the patient's arm. The patient sits sideways on the chair with their arm hanging over the backrest with a rolled towel placed under the axilla for padding. The clinician assumes a crouched position whilst holding the patient’s elbow and hand. Traction is gradually applied until reduction occurs (Guler, et al, 2015). This method was first described by Hippocrates in the 4th century BC (Mattick, 2000). Since then, the chair method has been described several times in the literature.

The Cunningham Method (Adduction)
The patient is seated with their elbow flexed and their hand resting on the clinician’s shoulder. The patient is encouraged to sit upright with their shoulders shrugged superiorly and posteriorly to retrovert the scapula and overcome the static obstruction of the glenoid rim. The clinician massages the bicep muscle to overcome the dynamic obstruction of the spasming musculature (Cunningham 2005).

Fares Method (Abduction)
With the patient lying supine, the extended arm is abducted to 90 degrees whilst performing gentle vertical oscillating movements. At 90 degrees the arm is externally rotated. Reduction usually occurs at approximately 120 degrees of abduction (Maity 2012).

The clinicians will have 0-5 minutes to attempt each methods and then move on to subsequent methods. The order of methods used to reduce the shoulder dislocation will be randomly applied to each patient. Participants may receive one, two or all three methods depending upon success/failure. For example, if Cunningham's (Method one) is unsuccessful, then FARES (method two) is applied. If FARES is unsuccessful, then Chair (method three) is applied.

Outcomes
Primary outcome [1] 328557 0
The primary aim of this study is to compare three biomechanically different shoulder reduction methods to determine which method is superior. Superiority being defined as success on first attempt at reduction of the shoulder. Success or failure of shoulder reduction will be assessed by confirmation with x-ray.

Intervention assignment
Other
Other design features
The method of randomisation will be by random number sequence. The order of method used to reduce the shoulder dislocation will be randomly applied to each patient. For example, study patient one is randomised to Cunninghams, Fares and then Chair in that order. The clinician has one attempt at reduction with each method. If the first method (Cunninghams) fails then the second method (Fares) is attempted. If the second method fails, then the third method (Chair) is attempted

Statistical methods / analysis
Data collected from the study will be entered into SPSS 25 (IBM Corp, 2013) for quantitative data analysis. Demographic information will be collated. Data will be analysed using descriptive statistics with medians or means with standard deviations and 95% confidence intervals.
We are planning a study with 75 experimental subjects in each of the 3 interventions, Chair, Cunningham's and FARES (Chair being considered the control intervention for the purpose of data analysis) . Prior data indicate that the failure rate among controls is 0.5 (Chair method). We will be able to detect true failure rates of .279 or .721 in exposed subjects with a power of 0.8 and an alpha of 0.05. Analysis of categorical variables will be completed with Pearson Chi-squared or Fisher Exact Test.

Summary
Brief summary
This study will compare three methods of relocating a dislocated shoulder. The three different methods being compared will use different positioning of the patient and their shoulder joint to relocate the shoulder. These methods are called the chair method, FARES method and Cunningham's method. The main purpose of the study is to determine which method is most effective at relocating the shoulder on first attempt.
