MRI imaging may follow, particularly if there is no specific evidence on radiographs, producing a three-dimensional reconstruction of the joint for better definition, to evaluate the hip cartilage, or measure hip socket angles (e.g. the alpha-angle as described by Nötzli [22] in 2-D and by Siebenrock in 3-D [23]).
Large osteophytes, marked joint space narrowing, severe sclerosis and definite bony deformity Osteoarthritis of the hip joint may also be graded by Tönnis classification . There is no consensus whether it is more or less reliable than the Kellgren-Lawrence system.
The first form is caused by a cam-deformity where extra bone is present on the femoral head, which leads to the head being non-spherical. The second deformity is referred to as a pincer deformity and it is due to an excess growth of the acetabular socket. [4] The third type of FAI is a combination of the first two deformities.
Protrusio acetabuli is an uncommon defect of the acetabulum, the socket that receives the femoral head to make the hip joint. The hip bone of the pelvic bone/girdle is composed of three bones, the ilium, the ischium and the pubis. In protrusio deformity, there is medial displacement of the femoral head in that the medial aspect of the femoral ...
Diagram of the bony pathology of both cam and pincer impingement Figure 7. A complex labral tear. An arthroscopic probe is seen at the junction of the labrum and acetabular rim. Hip arthroscopy was initially used for the diagnosis of unexplained hip pain, but is now widely used in the treatment of conditions both in and outside the hip joint ...
Osteoarthritis / Degenerative Joint Disease: This is the most common type of arthritis and is a continuous decay of cartilage, caused by friction within the joints through movement. Septic arthritis / Inflammatory Joint Disease: Septic arthritis is brought upon by infection or an inherited compromised immune system and is seen in the build up ...

Coxa vara is a deformity of the hip, whereby the angle between the head and the shaft of the femur is reduced to less than 120 degrees. This results in the leg being shortened and the development of a limp. It may be congenital and is commonly caused by injury, such as a fracture.
