Birmingham hip resurfacing prosthesis
Hip resurfacing is an alternative to hip replacement in a few very selected individuals. These individuals are young, physically very active and like to remain so after their operation.
In this operation the top of the thigh bone or femur is not sacrificed as in a total hip replacement. The bone is shaped to receive a metal cap. The socket is deepened and shaped to receive a metallic cup.
Indications for hip resurfacing
Primary osteoarthritis with good bone stock
Young and active individuals.
Advantages of hip resurfacing
Restoration of normal cadence.
Least incidence of dislocation.
Long survivorship of the implant.
Ideal candidates for Hip resurfacing
Patients should have normal hip anatomy and bone mineral density (BMD) Leg lengths should be equal. Ideal age is young men below 55 years. Large boned women with good BMD can also be considered.
Prostheses used - I routinely use the Birmingham hip resurfacing ( BHR) prosthesis.
Future advances- Trials are on for Plastic lined Hip resurfacing. (Polymix). This combination of metal on plastic will have the twin advantages of durability and lack of metal debris.
A single sided Hip resurfacing costs 8000 US dollars in a private room.
