Reduction of Anterior Glenohumeral Dislocation in Ventral Decubitus Versus Dorsal Decubitus Under Procedural Sedation

Study Overview
=================
Brief Summary
-----------------
The anterior glenohumeral dislocation is frequently encountered in emergency medicine. It represents about 50% of the total dislocation and affects 1 resident for 10 000 in France. In Nord Franche-Comte Hospital, 1 to 2 patients per day present this diagnosis in the emergency department, which requires reduction by external manoeuvres. A retrospective study shows the interest of the ventral decubitus compared to dorsal decubitus reduction in the care of patients with anterior glenohumeral dislocation. None prospective study has already demonstrate the interest of the ventral decubitus compared to the dorsal decubitus in the reduction of anterior glenohumeral dislocation. The main objective is to evaluate the speed of the reduction of the anterior dislocation of the shoulder by the ventral decubitus technique compared to the conventional technique in dorsal decubitus.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Sham Comparator: Dorsal decubitus<br>The dorsal decubitus reduction consists in placing the patient in the dorsal position and achieving reduction by traction maneuvers on the luxated upper limb. This maneuver generally requires procedural sedation. A mild traction of the traumatized limb in the axis is performed, with slight external rotation and progressive abduction. In the absence of reduction at this stage, this gesture is completed by a flexion adduction of the limb. A counterweight is then made by a rolled sheet and passed under the armpit of the patient. | Procedure: reductions<br>* Two reduction techniques are compared: dorsal decubitus and ventral decubitus reduction. The dorsal decubitus reduction consists in placing the patient in the dorsal position and achieving reduction by traction maneuvers on the luxated upper limb. This maneuver generally requires procedural sedation. A mild traction of the traumatized limb in the axis is performed, with slight external rotation and progressive abduction. In the absence of reduction at this stage, this gesture is completed by a flexion adduction of the limb. A counterweight is then made by a rolled sheet and passed under the armpit of the patient. The ventral decubitus reduction consists in placing the patient in the ventral position. The luxated limb is positioned in pendulum and the line of contact with the stretcher must pass through the mid-clavicular line. The humeral head is brought to the scapula.<br>|
| Experimental: Ventral decubitus<br>The ventral decubitus reduction consists in placing the patient in the ventral position. The luxated limb is positioned in pendulum and the line of contact with the stretcher must pass through the mid-clavicular line. The humeral head is brought to the scapula. | Procedure: reductions<br>* Two reduction techniques are compared: dorsal decubitus and ventral decubitus reduction.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The main objective is to evaluate the speed of the reduction of the anterior dislocation of the shoulder by the ventral decubitus technique compared to the conventional technique in dorsal decubitus. | The primary endpoint is the reduction time in minutes from inclusion of the patient after prior confirmation of the clinical and radiological diagnosis to the observed reduction. | 1 day | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Evaluation of the success rate of the ventral decubitus technique compared to the dorsal decubitus technique | Failure rate of the ventral decubitus technique compared to the dorsal decubitus technique | 1 day | 
| Evaluation of the consumption of sedative and analgesic treatments | Quantification of doses of analgesics and sedatives used | 1 day | 
| Evaluation of the time spent in emergency department | Time spent in emergency department | 1 day | 
| Evaluation of the pain felt before and after the intervention | Pain sensibility before, during et after the reduction techniques : visual analog pain scale | 1 day |
