Locked Neglected Anterior Shoulder Dislocation Treated With Open Reduction and Latarjet Procedure: A Case Report

Neglected anterior shoulder dislocations are rare and present significant diagnostic and therapeutic challenges due to progressive anatomical changes over time. Chronic cases often involve joint instability, bone erosion, and soft-tissue contractures, requiring complex surgical management.

We present the case of a 45-year-old male with a 6-month-old neglected anterior shoulder dislocation, initially misdiagnosed, and unsuccessfully managed with a closed reduction. Imaging revealed a significant Hill- Sachs lesion and minimal glenoid bone loss. Open reduction with the Latarjet procedure was performed through a deltopectoral approach to restore joint stability. Postoperatively, the patient showed substantial functional improvement with forward flexion of 150° at 6 months and minimal complications.

This case highlights the importance of early diagnosis and intervention in shoulder dislocations to prevent chronicity and the need for complex surgical procedures. The Latarjet procedure proved effective in managing chronic dislocations with significant bone loss, providing reliable stabilization and functional recovery. Early imaging and individualized treatment planning are crucial for optimizing patient outcomes.
