The hip joint is one of the body’s largest weight-bearing joints, located between the top of the thigh bone (femur) and the pelvis (acetabulum). It is a ball and socket joint in which the head of the femur is the ball and the pelvic acetabulum forms the socket. The joint surface is covered by smooth articular cartilage which acts as a cushion and enables smooth movements of the joint. Normally, the hip joint allows free movement in all directions.


  • Hip Arthritis (Osteoarthritis)

    • When the hip joint wears out the cartilage gradually disappears from the joint surfaces causing inflammation in the hip. Bone spurs​ develop at the edges of the joint and movement becomes restricted and painful.

  • Osteonecrosis of the femoral head (AVN)

    • In this condition the blood supply to the femoral head (the ball of the hip joint) is compromised due to various factors including steroid use, excessive alcohol intake and certain rare blood disorders. The bone subsequently collapses causing pain and stiffness in the joint.

  • Rheumatoid Arthritis

    • Due to chronic inflammation in the joint lining the cartilage surface is damaged and ​gradually disappears resulting in pain and restricted movement.

  • Hip Dysplasia

    • When the hip does not develop normally in childhood the socket may not fully cover the ball and the two do not match properly.​ This can lead to arthritis at a relatively young age.

  • Perthes Disease

    • This is caused by disturbance to the blood supply of the ball in children and if not severe can go unnoticed until adulthood when the deformity of the ball results in early arthritis.​

  • Hip Bursitis

    • The bursa is a small sack with a tiny amount of fluid in it overlying the side of the thigh bone at the hip (greater trochanter) allowing smooth sliding of a strong band over it. Due to injury or other precipitating factor it can get inflamed and painful requiring treatment.

  • Snapping Hip Syndrome

    • Various tendons around the hip can give a snapping sensation when jumping over bony prominences. The majority is not painful and does not require treatment.​



Total Hip Replacement (THR) procedure replaces all or part of the hip joint with an prosthesis to eliminate pain and restore joint movement.


Bursitis and snapping hips respond well to steroid injections. Some of these injections can be done blind while others need ultrasound guidance and are performed by specialized radiologists.
