An article appearing this year in Arthroscopy details a systematic review completed to determine if asymptomatic individuals show evidence on imaging of femoroacetabular impingement, or FAI. Cam, pincer, and combined lesions were included in the results. To read some basics about femoroacetabular injury, click here. Over 2100 hips (57% men, 43% women) with a mean age of 25 were studied. (Only seven of the 26 studies reported on labral tears.) The researchers found the following prevalence in this asymptomatic population:
Cam lesion: 37% (55% in athletes versus 23% in general population)
Pincer lesion: 67%
Labral tears: 68%
Mean lateral and anterior center edge angles: 30-31 degrees
The authors conclude that femoroacetabular impingement tissue changes and hip labral injury are common findings in asymptomatic patients, therefore, clinicians must determine the relevance of the findings in relation to patient history and physical examination. Because hip pain is a common comorbidity of pelvic pain, knowing how to screen the hip joint for FAI or labral tears, rehabilitate hips with joint dysfunction, and help someone return to activity following a hip repair is valuable to the pelvic rehabilitation therapist.
As the athletic population may have increased risk of hip injuries due to overuse, traumatic injury, or vigorous activity, being able to address dysfunction in both high level and less active patients is necessary. Herman & Wallace faculty member Steve Dischiavi has developed a course rich in athletic examples and including education about activating fascial systems in various planes.
