Anterior shoulder dislocation is a common orthopedic emergency that requires prompt reduction to relieve pain and restore joint function. Several techniques have been described for closed reduction, but the optimal method remains uncertain. The FARES (Fast, Reliable, and Safe) technique is a relatively new reduction method that may provide faster reduction with less pain compared with the conventional traction-countertraction technique.
This randomized controlled trial aims to compare the effectiveness and safety of the FARES technique and the traction-countertraction technique for the reduction of acute anterior shoulder dislocation in adult patients.
Eligible participants will be randomly assigned to receive reduction using either the FARES technique or the traction-countertraction technique. The study will evaluate the success rate of reduction, pain experienced during the procedure, time required for reduction, and procedure-related complications.
The findings of this study may provide evidence to guide the selection of reduction techniques for patients with acute anterior shoulder dislocation in the emergency department.
Acute anterior shoulder dislocation is one of the most common orthopedic emergencies and requires timely reduction to relieve pain, restore joint alignment, and minimize complications. Various closed reduction techniques have been described, but there is still no universal consensus regarding the optimal technique in terms of effectiveness, patient comfort, and procedural efficiency.
The FARES (Fast, Reliable, and Safe) technique is a relatively recent method for closed reduction of anterior shoulder dislocation. This technique combines gentle longitudinal traction, oscillating movements, and gradual abduction of the arm, aiming to facilitate reduction while minimizing patient discomfort. The traction-countertraction technique is a commonly used conventional method that relies on opposing forces applied by the operator and an assistant.
This study is designed to compare the outcomes of these two reduction techniques in adult patients with acute anterior shoulder dislocation. The study will evaluate whether the FARES technique provides advantages over the traction-countertraction technique regarding reduction success, pain during the procedure, reduction time, and safety outcomes.
The results of this trial may contribute to improving evidence-based decision-making for the management of acute anterior shoulder dislocation in emergency care settings.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Participants assigned to this arm will undergo closed reduction of acute anterior shoulder dislocation using the FARES (Fast, Reliable, and Safe) technique.
Procedure: FARES Technique
Participants assigned to this arm will undergo closed reduction of acute anterior shoulder dislocation using the conventional traction-countertraction technique.
Procedure: Traction-Countertraction Technique
Closed reduction of acute anterior shoulder dislocation using the FARES (Fast, Reliable, and Safe) technique.
Closed reduction of acute anterior shoulder dislocation using the conventional traction-countertraction technique.
Successful reduction at the first attempt
Proportion of participants achieving successful reduction using the assigned technique without requiring an alternative reduction method.
Time frame: During the initial reduction procedure
Time to successful reduction
The time required to achieve successful reduction, measured from the beginning of the assigned reduction maneuver until restoration of shoulder joint alignment.
Time frame: During the reduction procedure
Pain intensity during reduction procedure
Pain intensity experienced by participants during the reduction procedure, assessed using the Visual Analog Scale (VAS). The VAS is a continuous scale ranging from 0 (no pain) to 100 mm (worst imaginable pain), where higher scores indicate worse outcome.
Time frame: Immediately after completion of the reduction procedure
Number of reduction attempts
The number of attempts required to achieve successful shoulder reduction using the assigned technique.
Time frame: During the reduction procedure
Procedure-related complications
Incidence of complications related to the reduction procedure, including neurovascular complications and other adverse events.
Time frame: During the reduction procedure and immediate post-reduction assessment
Factors associated with successful reduction
Odds ratio (with 95% confidence interval) for successful reduction associated with each baseline factor, estimated using multivariable logistic regression. Successful reduction is defined as restoration of glenohumeral joint congruity confirmed on post-reduction radiography, achieved with the allocated technique without crossover to an alternative technique or the addition of procedural sedation. Baseline factors entered into the model are age (years), sex (male/female), body mass index (kg/m²), mechanism of injury (fall / sports-related / road traffic accident / other), time from injury to reduction attempt (hours), history of recurrent shoulder dislocation (yes/no), and associated greater tuberosity fracture on pre-reduction radiography (yes/no).
Time frame: From baseline assessment until completion of the reduction procedure
Pain intensity after reduction
Pain intensity after completion of the reduction procedure, assessed using the Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst imaginable pain).
Time frame: Immediately after successful reduction
Plan to share: No — Individual participant data will not be shared with other researchers. The collected data contain clinical information obtained from participants during the study, and sharing individual-level data was not included in the approved study protocol. Only aggregated and anonymized results will be reported in scientific publications.
