Concurrent Criterion-Related Validity of Physical Examination Tests for Hip Labral Lesions: A Systematic Review

Abstract

Hip injuries are prevalent, especially within the athletic population. Of the hip injuries in this population, some 18–55% are lesions to the labrum of the hip. Clinical diagnosis of hip labral lesions is di cult because data on prevalence are varied. In addition, data on the prevalence of internal and external risk factors are absent as are data on the cor- relation of these risk factors with labral lesions, making it di cult to gauge the diagnostic utility. e mechanism of injury is o en unknown or not speci c to labral lesions. Internal risk factors may remain hidden to physical therapists because in most jurisdictions, order- ing imaging tests is not within their scope of practice. Anterior inguinal pain seems highly sensitive for the diagnosis of patients with labral lesions but can hardly be considered spe- ci c; data on other pain-related and mechanical symptoms clearly have little diagnostic utility, making these data collected during the patient history almost irrelevant to diagnosis. By way of a comprehensive literature review and narrative and systematic analysis of the methodological quality of the retrieved diagnostic utility studies, this paper aimed to deter- mine a diagnostic physical examination test or test cluster based on current best evidence for the diagnosis of hip labral lesions. Current best evidence indicates that a negative nding for the exion-adduction-internal rotation test, the exion-internal rotation test, the im- pingement provocation test, the exion-adduction-axial compression test, the Fitzgerald test, or a combination of these tests provides the clinician with the greatest evidence-based con dence that a hip labral lesion is absent. Currently, research has produced no tests with su cient speci city to help con dently rule in a diagnosis of hip labral lesion. Suggestions for future research are provided.
