Condition
Anterior shoulder dislocation
Intervention
After fulfilling the study inclusion and exclusion criteria, each patient received a sequential registration number and a sealed, opaque envelope marked with the number corresponding to their registration. The envelope contained information regarding the treatment method that was randomly assigned to the patients registration number. The attending physician led the patient to a waiting room where after the door was closed and the envelope was opened, either intra-articular lidocaine injection was applied or no treatment was given in accordance to the method disclosed. In both cases, the anatomical region of the arm corresponding to the application of intra-articular anaesthetic was covered with dressings to mask whether or not the intervention had been performed. Whether or not the patients underwent the intervention, all patients were placed supine on a stretcher with the affected shoulder at 60° abduction. The pull maneuver and counter-traction were performed with a bedsheet placed under their armpit.

Lidocaine
Primary outcome measures
Pain was assessed through the application of a visual analogue scale at the time of pre reduction, and 1 and 5 minutes after the reduction maneuver was performed
Secondary outcome measures
1. The time span to achieve shoulder joint reduction in minutes
2. Neurological, vascular and infectious complications
3. Occurrence of failures were also assessed (defined as unsuccessful reduction after a 10-minute attempt). After 5 minutes, two other physicians were called to perform the reduction maneuver. Both were blinded to which treatment the patient had received.
