title: Clinical assessment of the glenoid labrum.
abstract: BACKGROUND
  The glenoid labrum is integral to shoulder stability and can be difficult to assess clinically. Whilst it is a single anatomical structure, damage to different regions results in very different clinical manifestations. A large number of provocative tests have been described, all of which initially purport to have excellent diagnostic accuracy. Clinical experience suggests that this is not the case and decision making can be difficult for the non-expert. The purpose of this study is to review the current evidence for the most commonly used tests and to provide suggestions for tests which have the most evidence for efficacy.
  
  
  METHODS
  The glenoid labrum was divided into anterior, superior and posterior regions. The English language literature describing labral tests was reviewed. The evidence provided by the authors and any subsequent studies was analysed.
  
  
  RESULTS
  Whilst a large number if tests have been described with the primary authors reporting excellent results the evidence for most is poor when later tested critically.
  
  
  CONCLUSIONS
  No single test will accurately diagnose labral pathology. The clinician must use evidence from the clinical history combined with selective use and interpretation of tests with which they are familiar.
