Poor bone quality

• For hip resurfacing surgery to be effective, the hip joint to be resurfaced has to have good quality bone stock. Poor quality bone, whether overly soft or misshapen, can prevent adequate resurfacing of the hip joint and is a major reason not to have hip resurfacing surgery.
  
  

Avascular necrosis

• Avascular necrosis, which is a hip disease that causes the hip bone to become brittle and in many cases deformed, is generally a major reason not to have hip resurfacing surgery. This disorder can cause a hip resurfacing implant to fail.
  
  

Previous hip surgery

• Previous hip joint surgery that resulted in a significantly deformed or altered hip joint is a major reason for not having hip resurfacing surgery. Severely altered hip joint anatomy would not permit adequate placement and fixation of a hip resurfacing prosthesis.
  
  

Age

• Being skeletally immature is a major reason not to have hip resurfacing surgery. Hip resurfacing surgery is only performed on individuals who have reached their maximum adult height, i.e., have reached skeletal maturity.
  
  

Osteoporosis

• Individuals with osteoporosis are oftentimes poor candidates for hip resurfacing surgery. Strong, healthy bone is a requirement in order to successfully implant the hip resurfacing prosthesis directly onto the hip (femur) bone. Osteoporosis can make the hip bones brittle and weak, which can prevent adequate implantation of the prosthesis.
