Risks related to ANY surgery:

Risks and complications relative to total hip replacements and hip resurfacing:

Fracture of the femur
Nerve injury
Deep vein thrombosis
Leg length discrepancies

Traditional THR (22-32mm femoral head): 2-4% risk for first hip replacement with a 1% increase every 5 years to a maximum of 7% at 25 years.  14-15% risk after revision to a second hip replacement.

Large head THR & resurfaced hip (38-51mm femoral head)Risk less than 1% (i.e. .3%)


Heterotopic ossification  (Growth of excess bone around the joint)
