"Psoas tendinitis is an important reason for groin pain in resurfacing surgery . This is peculiar to resurfacing as the cup for resurfacing is a very large profile ie half a sphere. Nearly all THR cups are only portions (arc) of a hemisphere.

What is a Avascular Necrosis?

Avascular necrosis is a disease resulting from the temporary or permanent loss of the blood supply to the bones.[1] Without blood, the bone tissue dies and causes the bone to collapse.[1] If the process involves the bones near a joint, it often leads to collapse of the joint surface. This disease also is known as osteonecrosis, aseptic (bone) necrosis, and ischemic bone necrosis.[1]

What is Legg – Calve Perthes Disease

Perthes disease affects the hip joint. The hip joint is a ball and socket joint, the ball is the femoral head and the socket or cup is the acetabulum. Perthes disease causes avascular necrosis of the femoral head. This means that the blood supply to the femoral head is disrupted causing some of the bone to die. As part of the body's normal healing process, the body breaks down this dead bone before new bone is made. But the resorption of this dead bone leads to structural weakness causing collapse and deformity.

Femoroacetabular refers to the place where the femur (thigh bone) and acetabulum (hip socket) meet. Impingement means pinching.

What is a Femoral Osteotomy?

Proximal femoral osteotomy is currently commonly used for adults in the treatment of hip fracture nonunions and malunions and in cases of congenital and acquired hip deformities.

What is a Heterotopic Ossification?

Attempted frog-leg, lateral radiograph of the left hip. Mature heterotopic ossification (HO) surrounds the greater and lesser trochanters of the femur in this patient, who had a bipolar hip prosthesis placed 2 months earlier. The large amount of HO resulted in a significantly reduced range of motion.

What is a Hip Dysplasia?

Hip dysplasia, developmental dysplasia of the hip (DDH)[1] or congenital dysplasia of the hip (CDH)[2] is a congenital or acquired deformation or misalignment of the hip joint.

A helpful website for hip dysplasia is the International Hip Dysplasia Institute

What is the Neck Capsule?

Capsule of hip joint
The articular capsule (capsular ligament) is strong and dense.
Above, it is attached to the margin of the acetabulum 5 to 6 mm. beyond the glenoidal labrum behind; but in front, it is attached to the outer margin of the labrum, and, opposite to the notch where the margin of the cavity is deficient, it is connected to the transverse ligament, and by a few fibers to the edge of the obturator foramen.

What is a Osteoarthrits?

Osteoarthritis (OA, also known as degenerative arthritis, degenerative joint disease), is a clinical syndrome in which low-grade inflammation results in pain in the joints, caused by abnormal wearing of the cartilage that covers and acts as a cushion inside joints and destruction or decrease of synovial fluid that lubricates those joints.

What is Sciatica

Did you know that the sciatic nerve is the longest nerve in your body? It runs from your lower back, through your glutes, and down the back of each leg. No wonder it causes so many long lingering problems. This long nerve controls many of the muscles and sensations in your legs. After hip resurfacing surgery, sometimes, although rarely, this nerve can get irritated.
