The Labrum is the cartilage lip surrounding the periphery of the Hip Socket (Acetabulum). It is similar in structure to the Labrum in the Shoulder often injured in Disloactions, as well as the Meniscus in the Knee.
The diagnosis of Hip Labral Tears has become more common with the use of MRI scans. While we have know about these Labral tears for many years, it is only more recently that the concept of FAI (Femoral Acetabular Impingement) has become more well known.
This basically means that the Labral tear is commonly the result of impingement of part of the Femur (Thigh bone) against the Hip Socket (Acetabulum). This causes damage to the Labrum much like a Meniscal tear in the knee. The damaged and detached Labrum can then lead to secondary damage to the Cartilage of the Socket and causing premature Osteoarthritis in this young age group.
With the recent advances in Arthroscopy of the Hip (Keyhole Surgery), we are able to address these problems with Minimally Invasive Techniques. The torn Labrum can be cleaned up or repaired much like a torn Labrum in a Disloacted Shoulder. The prominent bone on the Femoral Neck (also known as the CAM deformity) causing the impingement can be removed to stop the recurrence of the tear, and therefore hopefully to preven the progression to OsteoArtthritis in these young adults.
