A Modified Chair Technique for Acute Anterior Shoulder Dislocation Compare With Traction-counter Traction Technique

Anterior shoulder dislocation is the most common type of joint dislocation and requires timely and effective closed reduction. The traction-counter traction technique is widely used in Thailand, although it may require patient transfer and sedation, which can increase the risk of adverse events. The modified chair technique has been introduced as a simpler, potentially more convenient method that may allow reduction to be performed in a single location

  • Patients with multiple traumatic injuries involving.

Treatment and study plan

Modified chair technique

Procedure

Modified Chair Technique is a closed reduction method for acute anterior shoulder dislocation that adapts the traditional chair technique to improve convenience and safety in the emergency setting. Instead of using a standard chair backrest, this modified approach utilizes the side rail of a patient transport stretcher, which serves as a stable fulcrum beneath the patient's axilla.

Traction-counter traction technique

Procedure

Traction-Counter Traction Technique is applying longitudinal traction to the affected arm while simultaneously providing counter traction across the patient's torso, allowing controlled separation of the humeral head from surrounding soft tissues to facilitate reduction.

Primary outcomes

  1. To compare the success rate of shoulder reduction between the modified chair technique and the traction-counter traction technique in patients with acute anterior shoulder dislocation.

    Time frame: immediate after procedure

Secondary outcomes

  1. To compare the level of pain during the shoulder reduction procedure between the modified chair technique and the traction-counter traction technique.

    Time frame: immediate after procedure

    we record pain with visual analog scale range from 0 to 10

  2. Evaluate the complications associated with shoulder reduction from using the modified chair technique and the traction-counter traction technique.

    Time frame: 30 minute after procedure

    Complication such as brachial plexus injury, proximal humerus fracture, muscle spasm
