Recent NICE guidelines suggest that Total Hip Arthroplasty (THA) be offered to all patients with a displaced intracapsular neck of femur fracture who: are able to walk independently; not cognitively impaired and are medically fit for the anaesthesia and procedure. This is likely to have significant logistical implications for individual departments.

Data from the National Hip Fracture Database was analysed retrospectively between January 2009 and November 2011. The aim was to determine if patients with displaced intracapsular neck of femur fractures admitted to a single tertiary referral orthopaedic trauma unit received a THA if they met NICE criteria. Case notes were then reviewed to obtain outcome and complication rates after surgery.

Five hundred and forty-six patients were admitted with a displaced intracapsular neck of femur fracture over the described time period. Sixty-five patients met the NICE criteria to receive a THA (mean age 74 years, M:F = 16: 49); however, 21 patients had a THA. The other patients received either a cemented Thompson or bipolar hemiarthroplasty. Within the THA cohort there were no episodes of dislocation, venous thromboembolism, significant wound complications or infections that required further surgery. Within the hemiarthroplasty cohort there was 2 mortalities, 2 implant related infections, 1 dislocation and 2 required revision to a THA.

There is evidence to suggest better outcomes in this cohort of patients, in terms pain and function. There is also a forecasted cost saving for departments, largely due to the relative reduction in complications. However, there were many cases (44) in our department, which would have been eligible for a THA, according to the NICE guidelines, who received a hemiarthroplasty. This is likely a reflection of the increased technical demand, and larger logistical difficulties faced by the department. We did note more complications within the hemiarthroplasty group, however, the numbers are too small to address statistical significance, and a longer follow up would be needed to further evaluate this. There is a clear scope for optimisation and improvement of infrastructure to develop time and resources to cope with the increased demand for THA for displaced intracapsular neck of femur fractures, in order to closely adhere to the NICE guidelines.
