Hip Resurfacing

Hip resurfacing (hip resurfacing arthroplasty) is the procedure that involves trimming and capping of the femoral head with a smooth metal covering instead of its removal. The damaged bone and cartilage within the socket is removed and replaced with a metal shell, just as in a traditional total hip replacement.

Candidates for Hip resurfacing surgery

  • More advanced osteoarthritis

  • Exhausted the nonsurgical treatment options

  • Hip pain that is significantly affecting the quality of life and interfering with normal activities.

  • Younger (less than 60), larger-framed patients (often, but not always male) with strong, healthy bone

Procedure of Hip resurfacing

A hip resurfacing operation typically takes 1 1/2 to 3 hours and is performed under general or regional anaesthesia. The surgeon makes an incision in the thigh to reach the hip joint. The femoral head is then dislocated out of the socket and is trimmed using specially designed power instruments. This is followed by cementing of a metal cap over the prepared femoral head and removal of the cartilage that lines the socket. The metal cup is pushed back into the socket and held in place by friction between the bone and the metal. Finally the femoral head is relocated back into the socket and the incision is closed.

Patient is kept under observation in the recovery room for any kind of complications or risks associated with the surgery.

Advantages of Hip resurfacing

The advantages of hip resurfacing over traditional total hip replacements are:

  • Easier to revise in case the implant wear out or loosen over time

  • Decreased risk of hip dislocation

  • Better walking pattern

  • Improved ability to perform daily activities

  • Restores physiologic biomechanics

  • Preserves bone stock

  • Less blood loss and a reduced need for blood transfusion

Disadvantages of Hip Resurfacing

  • Risk of femoral neck fracture

  • Metal ion risk as a metal ball moves within a metal socket

  • Larger incision is usually required for a hip resurfacing
