A Locked Posterior Shoulder Dislocation: An Injury Not to Miss

Area of Science:

• Orthopedic Surgery
• Traumatology

Background:

• Locked posterior shoulder dislocation is defined as an unreduced dislocation lasting over three weeks, often accompanied by other injuries.
• Complex shoulder injuries require prompt and accurate diagnosis for effective management.

Observation:

• A 38-year-old male presented with severe pain and functional loss from a posterior glenohumeral dislocation, reverse Hill-Sachs lesion, and clavicle fracture.
• Initial closed reduction attempts were unsuccessful, necessitating surgical intervention.

Findings:

• The McLaughlin technique, involving subscapularis tendon transfer to the reverse Hill-Sachs lesion secured with bone anchors, was performed.
• Post-surgery, the patient achieved full range of motion without recurrent dislocation.

Implications:

• This case underscores the importance of maintaining high clinical and radiological suspicion for complex posterior shoulder injuries.
• Timely surgical management, such as the described technique, is crucial for favorable outcomes in rare and severe shoulder dislocations.
