Introduction: The management of osteonecrosis (ON) of the femoral head remains controversial. It is unclear the extent to which non-arthroplasty procedures are used and there has been no previous report of the trends in operative management of ON in the UK. Our objective is to report current trends in management of ON of the femoral head amongst specialist hip surgeons in the UK. Methods: A single-stage internet-based survey was e-mailed to 352 eligible members of the British Hip Society (BHS). This consisted of 10 question stems including 16 hypothetical clinical scenarios with imaging. Results: 115 active Consultant members of the BHS completed the survey. For symptomatic pre-collapse ON we found core decompression (CD) was the most common operative intervention and for post-collapse ON we found that total hip arthroplasty (THA) was the most common operative intervention. We found no difference in the rate of operative intervention between 24 and 48-year-old patients at any stage of ON but joint preserving procedures were more often selected for the younger patient and arthroplasty for the older patient. Surgeons were more likely to offer arthroplasty to a 48-year-old patient at an earlier stage of disease. Conclusions: Our respondents would offer different operative interventions dependent on stage of ON and patient age. Core decompression (CD) and arthroplasty were common but variation in treatment options offered suggests a lack of consensus amongst UK hip surgeons. We suggest that further research such as a prospective RCT is needed to gain consensus on management of this condition.
