Osteonecrosis of the femoral head: Part 2— Options for treatment

SummaryThe management of osteonecrosis of the hip is evolving but remains challenging. As the patients are typically younger, it remains imperative to preserve the femoral head for as long as is possible. When arthroplasty is indicated, the need for longevity of implants and bearing surfaces is paramount. Developments in bone biology, the use of appropriate pharmacology, improved implant design, better bearing surfaces and appropriate choice of implant fixation should all improve the historically poorer results seen with arthroplasty in osteonecrosis patients.
