United KingdomAccording to Dr Beaulé, the following patient selection factors can favourably impact modern resurfacing outcomes:
- no large femoral head cyst;
- no osteopenia/osteoporosis;
- 65 or younger
- no prior hip surgery.
He says "My current ideal indications for hip resurfacing are patients age less than 60 years, risk index less than or equal to 3."
The risk index is a tool for determining how various factors may interact for a reproducible outcome. SARI gives
- 2 points each for a femoral head cyst larger than 1 cm cubed and patient weight less than 82 kg. - 1 point each for previous hip surgery and UCLA activity score above 6 for a total possible score of 6.
The higher the patient’s SARI, the greater the risk of failure.
Beaulé applied the index in a study he did of 400 patients following resurfacing. The overall series showed a survivorship of 94% at 4 years which most would consider suboptimal compared to THR.
After grouping patients by SARI, survivorship increased to 97% in those with SARI equal to or less than 3. But it decreased to 89% when the index was equal to or greater than 3.
