Arthroscopic capsulolabral posterior reconstruction offers advantages in posterior shoulder instability, according to researchers.
More than 90% of athletes treated for the condition in this manner are able to return to sports, Dr. James P. Bradley told Reuters Health by email.
While glenohumeral instability is relatively common, affecting 2% of the general population, posterior instability is much rarer, affecting 2% to 10% of all unstable shoulders, according to a 2011 paper in Sports Medicine. Posterior glenohumeral instability is mainly seen in athletes.
In a June 26 online paper in The American Journal of Sports Medicine, Dr. Bradley of the University of Pittsburgh Medical Center and colleagues observe that there are few reports of arthroscopic treatment of unidirectional posterior shoulder instability.
