Hip impingement is a disorder caused by excess bone and, therefore, lack of space between the neck of the femur and the rim of the socket.
This lack of space causes the neck and rim of the socket to rub together, particularly when the hip is flexed, which leads to pain and, potentially, early onset of arthritis. The primary symptom of hip impingement is pain in the hip area during or after the hip has been in a flexed position, such running or jumping or sitting for long periods.
If your impingement is causing pain or limiting movement in everyday activities, an orthopedic surgeon may recommend arthroscopic or open surgery.
Arthroscopy - During an arthroscopic procedure, miniature instruments are inserted into small incisions made in the hip. Then the head of the femur and/or the socket are reshaped by removing excess bone.
In more severe cases or if other repairs are necessary, an open surgery may be required to repair the impingement. In this procedure, the head of the femur and/or socket are also reshaped by removing excess bone, but a large incision is made to access the hip.
