Aim: To establish the surgical treatment of displaced intracapsular femoral neck fractures in hospitals across the United Kingdom.

Methods: The on-call registrars in all 223 hospitals receiving acute orthopaedic admissions in the UK, were interviewed by telephone. Their usual practices were recorded for two groups of patients, active and frail. The proportions of hospitals using the different surgical options were determined.

Results: Despite stereotyped clinical features, management varied between specialists within some hospitals: two or more different methods of treatment were in routine use for active patients in 22% of hospitals, and for frail patients in 27%. The management also varied between hospitals. Overall, for active patients, bipolar hemiarthroplasty was in use in 41%, internal fixation in 37%, unipolar hemiarthroplasty in 32% and total hip replacement in 16% of hospitals. For frail patients either Austin-Moore or Thompson prostheses or both were in use in 94% of hospitals. Where used, Austin-Moore prostheses were uncemented in 93% of hospitals, and Thompson prostheses cemented in 79%. Bipolar prostheses were in use in 8%, and the alternative of internal fixation undertaken for frail patients in 1% of hospitals.

Conclusions: The findings demonstrated a lack of consensus in several aspects of the treatment of displaced intracapsular fractures of the femoral neck, with implications for consideration of best practice, in the UK, and worldwide.
