Hip Resurfacing Failure Symptoms

Hip resurfacing has a high failure rate of 8- 10 %. Most failures occur within five to ten years. It commonly fails in dysplastic hips, Avascular necrosis and short women. Reasons for hip resurfacing failure are improper technique, wrong patient selection, and inherent complications.

Problems associated with failed hip resurfacing are:

  • Soft tissue destruction

  • Bone loss

  • Implant loosening

  • Osteonecrosis

  • Femoral neck fracture

Causes for failure of hip resurfacing

Main causes are:

  • Socket loosening

  • Socket malposition

  • Femoral neck fracture

  • Femoral component loosening

  • Pseudo tumors

  • ALVAL lesions

Though hip resurfacing with the ASR was first to be reported, the Birmningham hip resurfacing (BHR) and other devices also have a moderate failure rate.
Symptoms of failure are pain, limp and deformity.
Diagnosis-
X rays may show alteration in the position of the components. Hip aspiration may reveal a black coloured fluid. Blood metal ion levels may be elevated. 

Treatment

The salvage of a failed hip resurfacing can be done with total hip replacement. A short stem hip replacement is another option. As most patients who underwent hip resurfacing are young or middle aged, a total hip arthroplasty may be too drastic for them. In this scenario, a short stem hip replacement is a better alternative. It can postpone a total hip replacement by several years.
