简要总结
The primary objective of the pilot study is to assess the feasibility of a definitive trial to determine the effect of arthroscopic soft tissue stabilization vs. non-operative management on the risk of recurrent anterior dislocation rates and functional outcomes following in patients presenting with a first-time dislocation (FTD) over a 24-month period.
详细描述
Background
The shoulder is the most commonly dislocated joint in the body with a global incidence that ranges from 15 to 25 per 100 000 people. It is estimated that approximately 70 000 shoulder dislocations occur annually in the United States. In North America, a sampling of individuals presenting with shoulder dislocations to US emergency departments identified an overall incidence rate in the United States of 24 (95% confidence interval, 20.8 to 27.0) per 100,000 person-years and a maximum incidence rate (47.8 [95% confidence interval, 41.0 to 54.5]) occurring in those between the ages of twenty and twenty-nine years. A review of shoulder reductions performed in emergency rooms in Ontario, Canada between 2002 and 2010 identified 719 dislocations affecting primarily young patients with a median age of 35 years and 74% male. The incidence density rate of shoulder dislocations was found to be 23/100,000 person-years and highest among young males (98/100,000 person-years).
Recurrence mainly occurs in the first 2 years after the first anterior shoulder dislocation event, and recurrent instability significantly affects quality of life, sport, and professional activities.4 Epidemiologic data suggests that younger patients are at significantly higher the risk of recurrence. In a prospective study of 252 patients by Robinson et al, the recurrence rate after 5 years reached 86.6% in patients aged 15 to 20 years, 73.8% in patients between 21 and 25 years of age, and 46.8% in patients between 26 and 30 years of age. Participation in contact and overhead throwing sports and higher sporting levels also increases the risk of recurrence.
Management options in patients with a first-time shoulder dislocation include non-operative and operative approaches.
Anterior dislocations often injure the anterior and inferior glenoid labrum, described as the Bankart lesion. This lesion was observed arthroscopically in 94% to 100% of patients and often result in long-term instability. Thus, there is debate as to whether arthroscopic Bankart repair should be routinely performed in patients after a first-time anterior shoulder dislocation.
