Scientific titleThe effectiveness of a specially designed shoulder chair for closed reduction of acute shoulder dislocation in the emergency department: a prospective, unblinded randomised controlled trial
Study objectivesThe aim of this study is to demonstrate the effectiveness of the new reduction method by measuring:
1. Length of patient accident and emergency (A & E) stay
2. Length of the procedure
3. Successful reduction rate
4. Levels of pain experienced by patients in different time periods before and after the reduction
Ethics approval(s)The Joint Chinese University of Hong Kong (CUHK) and New Territories East Cluster (NTEC) Clinical Research Ethics Committee gave approval on the 13th October 2008 (ref: CRE-2008.326-T)
Health condition(s) or problem(s) studiedAcute shoulder dislocation
InterventionSubjects will be randomly assigned into two study groups. In the normal practice group, the Kocher's manoeuvre will be suggested as a primary reduction technique. Emergency physicians can also use any recognised method for closed reduction according to their preferences and clinical judgment. Physicians should follow the pre-established study analgesic and sedation pathway to give medication. In the shoulder chair group, shoulder reduction will be performed by emergency physicians or emergency nurse practitioners.

Oral medication:
In both groups, oral paracetamol 1 g will be used.

Intravenous medication:
Both groups can have rescue analgesia - intravenous morphine 2 mg (increments as required) if patient requests.

In addition, for the normal practice group, intravenous 2 mg of midazolam will be used before conducting the reduction. Physicians can titrate 1 mg every 2 - 3 minutes to improve conditions to allow a satisfactory level of sedation for reduction.
