It involves the surgical correction of any bony abnormalities causing the impingement and correction of any soft tissue lesions, such as labral tears. [6] The primary aim of surgery is to correct the fit of the femoral head and acetabulum to create a hip socket that reduces contact between the two, allowing a greater range of movement. [30]
Tears of the hip labrum can be classified in a variety of ways, including morphology, etiology, location, or severity. [4] Anatomical modifications of the femur and or hip socket cause a slow buildup of damage to the cartilage. Femur or acetabular dysplasia can lead to femoral acetabular impingement (FAI).
The acetabular labrum reduces the size of the opening of the acetabulum and deepens the surface of the hip joint. At the lower part of the acetabulum is the acetabular notch, which is continuous with a circular depression, the acetabular fossa, at the bottom of the cavity of the acetabulum.
A hip impingement is when the thigh bone and socket rub together, which can lead to pain and restricted motion. It’s caused by abnormally shaped bones — an issue that usually develops before ...
In contrast, pincer impingement is a result of an abnormality on the acetabular side of the hip joint. [2] The acetabulum may either have a more posterior orientation than normal, otherwise known as acetabular retroversion (seen as the crossover sign on AP radiographs), or there may be extra bone around the rim.
In addition, an internal rotation of the respective hip joint is either not possible or accompanied by pain when forcefully induced. [2] The positive Drehmann sign is a typical clinical feature in slipped capital femoral epiphysis (SCFE), the impingement syndrome of the acetabulum-hip, or in osteoarthritis of the hip joint. [3]
Pain in the groin, called anterior hip pain, is most often the result of osteoarthritis, osteonecrosis, occult fracture, acute synovitis, and septic arthritis; pain on the sides of the hip, called lateral hip pain, is usually caused by bursitis; pain in the buttock, called posterior or gluteal hip pain, which is the least common type of hip ...
The hip joint is a ball-and-socket synovial joint, formed by an articulation between the femur and acetabulum. Intra-articular etiology of hip pain includes osteoarthritis, inflammatory arthropathy, acetabular labral tears and femoro-acetabular impingement.
