An Overview of Acetabuloplasty for Pincer Impingement
The hip condition femoroacetabular impingement (FAI) occurs when a bone abnormality develops in one or more hip bones. Commonly found in younger, active adults who are involved in sports requiring repetitive hip motions, the abnormality can affect the femoral head (ball), the acetabulum (socket) or both. When the condition is present on the acetabular side, it is characterized as pincer impingement. Acetabuloplasty, a pincer impingement surgery, may be recommended by Dr. Jervis Yau, hip surgeon, in Santa Barbara, Goleta, Santa Maria and Ventura, California patients affected by severe impingement.
What Causes Pincer Impingement?
Pincer impingement occurs when extra bone extends out over the acetabulum’s normal rim. The over-coverage is caused from the acetabulum (socket) being too deep, or is mal-rotated. This results in the labrum becoming trapped during certain hip movements. Over an extended period of time, the labrum may tear and damage the underlying articular cartilage.
Dr. Yau will perform a complete medical review and physical examination to determine if non-surgical measures or a pincer impingement surgery is required to alleviate a patient’s painful symptoms. Conservative measures include rest, activity modifications and a physical therapy program. The physical therapy program is designed to strengthen the core and the muscles surrounding the hip joint.
An acetabuloplasty may be recommended by Dr. Yau if non-operative measures fail to alleviate symptoms or if the case of pincer impingement is too severe. Dr. Yau commonly performs an arthroscopic pincer impingement surgery to remove the over-coverage area on the acetabulum. This relieves the bony impingement and creates additional space, allowing the hip to have a normal range of motion. If a patient is affected by both pincer and cam impingement, Dr. Yau may be required to perform both an acetabuloplasty and a femoroplasty (cam impingement surgery).
