What is cam type femoroacetabular impingement (FAI)?
Femoroacetabular impingement (FAI) is ‘impingement’ or abnormal contact between the ball (femoral head) and socket (acetabulum) of the hip joint. The cam lesion (or femoral neck ‘bump’) refers to the abnormally-shaped femoral head, which comes into abnormal contact with the edge of the hip socket, thus limiting the range of movement in the hip. This contact frequently results in damage (or tears) to the cartilage along the rim of the socket (i.e., the labrum) or to the cartilage lining the socket (i.e., the articular cartilage). Tears of the hip ligament (i.e., ligamentum teres) may also result.
Revision Hip Replacement
Revision hip replacement means that part or all of your previous hip replacement needs to be revised. This operation varies from very minor adjustments to massive operations, replacing significant amounts of bone, and is hence difficult to describe in full.
Total hip replacement (THR) replaces all or part of the hip joint with an artificial device (prosthesis) with a plastic liner in between to restore joint movement.Read More
Ligamentum Teres Repair
What is a Ligamentum Teres Repair?
The ligamentum teres is a ligament located deep in the hip joint. It connects the ball (femoral head) to the socket (acetabulum) and provides blood supply to the femoral head. It is also important for stability. Numerous nerve fibres run through the ligamentum teres and injuries to this ligament result in severe hip pain.
Ligamentum teres tears are notoriously difficult to diagnose. Most patients will have had multiple investigations performed before the diagnosis is made or suspected.
Gluteus Medius Repair
Gluteus medius is one of 3 muscles in the buttocks and is situated on the outer surface of the hip. The function of the gluteus medius is to assist with pelvis stability, hip abduction, along with internal and external rotation of the hip. Tears of the gluteus medius usually occur where the tendon inserts at the greater trochanter, causing lateral hip pain.
Tears of the gluteus medius can occur due to traumatic injury or degenerative conditions such as tendinopathy (chronic inflammation of the gluteus medius tendon). Gluteus medius tears cause pain and weakness on the affected side of the hip.
