Randomized comparison of oxinium vs. metal against conventional and highly cross-linked polyethylene in THA.
Author: Hamadouche and Courpied

The purpose of this study was to compare the effect of femoral head material (oxinium vs. metal) on polyethylene wear in two consecutive prospective randomized series of low friction total hip arthroplasty.

Ganglion Cysts

Ganglion Cysts


Ganglion cysts are benign, fluid filled lumps that arise from joints and sometimes, from tendon sheaths. They are generally round or oval in shape and are, by far, most common in the wrist. The single most common location in the wrist is on the "back" or posterior side with the second most common location on the palm side of the wrist near the radial artery. The radial artery is where your "pulse" is usually felt. When these cysts occur near finger joints, they are sometimes referred to as mucous cysts.

Carpal Tunnel Syndrome

Carpal Tunnel Syndrome

In the words carpal tunnel syndrome, the anatomy of the diagnosis is implied. Carpal, meaning wrist, and tunnel referring to a channel in the wrist conceptually formed by the bones of the wrist on three sides and the roof made of the thick transverse carpal ligament is the space in which the median nerve passes into the hand.

Tennis Elbow / Golfer's Elbow

Tennis Elbow / Golfer's Elbow

Tennis elbow is also known as lateral epicondylitis. It is common in the racket arm of tennis players, but physicians see it more often in non-tennis playing patients. The tendons on the outside, or lateral, part of the elbow become inflamed and tendonitis develops. A golfer’s elbow is essentially the same process, except it develops on the inside, or medial portion of the elbow.

Revision Total Hip Replacement

Revision Total Hip Replacement

Revision total hip replacement can be a complex procedure where one or more of the components of a total hip replacement need to be exchanged. Some of the causes for the need of revision hip replacement include:
  • Polyethylene wear, (plastic).
  • Recurrent dislocation.
  • Infection.
  • Loosening/pain.
  • Fracture around or below the implant.
  • Breakage of a component.

Total Hip Replacement Surgery

Total Hip Replacement Surgery

Physical Therapy Arthritis is the gradual loss of cartilage over the hip joint surfaces. It can be caused by osteoarthritis, which is more common, and rheumatoid arthritis. Numerous other conditions can lead to the formation of osteoarthritis (avascular necrosis, trauma, developmental deformation)

Alternative Bearing Surfaces

Alternative Bearing Surfaces

Alternative bearing surfaces have shown tremendous potential in extending the durability of hip replacement surgery. The alternative bearing concepts involve metal on metal or ceramic on ceramic surfaces.
