Hip Resurfacing

It is a surgical bone conserving alternative to Total Hip Replacement (THR).

Hip Resurfacing doesn’t replace the ball of the hip with a metal or ceramic ball; instead the damaged hip ball is reshaped & capped with a metal prosthesis & fitted. It is recommended in young & middle age people having hip arthritis. Patients having advanced bone loss, altered anatomy, limb length discrepancy, kidney disease, metal allergy are not advisable for Hip Resurfacing. In Hip Resurfacing a cobalt-chrome metal cap (shaped like mushroom) is placed over the head of femur while a matching metal cap is placed in the pelvic socket, replacing the articulating surfaces of the hip joint & removing very little bone.  In this most of the bone is preserved (Head & Neck portion of the femur bone is retained). The component used in Hip Resurfacing (surface components are of metal & outer side of socket is lined with either a porus metal or hydroxyapatite coating) matches the normal size of the natural bone.

Though risks after Hip Resurfacing are similar to THR, but it is less traumatic, faster recovery plus rapidly fixes the pain & allows return of full mobility. Disadvantages are rare like aseptic loosening, metal wear, femoral neck fractures… Long term results of Hip Resurfacing are still unknown as it has been in clinical usage for past 6 years
