Acetabuloplasty as a Pincer Impingement Treatment
Femoroacetabular impingement (FAI) is a condition where abnormal contact occurs between the bones of the hip. This abnormality commonly affects the hip joint in young and middle-aged adults who are involved in repetitive sports. The ball (femoral head) can impact the socket (acetabulum) and lead to degeneration within the joint. FAI has different names depending on what part of the hip has a bony abnormality. For example, pincer impingement occurs when extra bone extends out over the normal rim of the acetabulum. Acetabuloplasty, a surgical pincer impingement treatment, may be recommended by Dr. Jeff Padalecki, Austin, Round Rock, and Cedar Park, Texas communities orthopedic hip surgeon, in severe cases of pincer impingement.
What Causes Pincer Impingement?
Pincer impingement occurs when the abnormality involves the acetabular side of the joint. This condition creates over-coverage of the joint because the acetabulum is too deep and extends beyond the normal boundaries, or is mal-rotated. This results in the labrum becoming trapped between the femoral head and neck with motion of the hip. Over time, the labrum will tear and the underlying articular cartilage will be damaged.
The majority of patients with femoroacetabular impingement are diagnosed to have a mixed type, showing symptoms and traits of both pincer and cam (involving the femoral side of the hip joint) impingement.
How Is FAI Treated?
In the past decade, much has been learned about how to treat FAI. After conducting a thorough examination, Dr. Padalecki will assess if non-surgical techniques will work to treat the condition. This usually involves rest, activity modification and physical therapy to strengthen the core muscles around the hip. Injections may also be used for diagnostic and therapeutic purposes. If a patient continues to have ongoing hip pain, then a surgical pincer impingement treatment is usually recommended to correct the bony conflict.
