The Natural History of Anterior Shoulder Instability in Patients Over the Age of 50: A Population Based Study

Video Transcription

Video Summary

The video discusses the research findings on first-time anterior shoulder dislocation in patients over the age of 50. It reveals that nearly 20% of all shoulder dislocations occur in this age group, with an incidence rate of 28.8 per 100,000 person-years. Older patients have a decreased risk of recurrent dislocations but an increased risk of associated rotator cuff tears. The study utilized the Rochester Epidemiology Project and identified 179 patients. Concomitant injuries included Hill-Sachs and Boney-Bankart lesions, while full-thickness rotator cuff tears were observed in 62% of patients. Surgical intervention was required by 47 patients, and 15% experienced recurrent instability. Ultimately, 14% developed arthritis, with 8 requiring shoulder arthroplasty. The study found an increase in MRI utilization and surgical interventions over time. The limitations of the study include its retrospective nature and lack of objective data on strength and range of motion. Overall, the study provides insights into the incidence, characteristics, treatment, and outcomes of first-time anterior shoulder dislocation in patients over the age of 50.
