Bipolar hemiarthroplasty(BPHA) for displaced intracapsular neck of femur fractures(DICNOF) is a controversial topic as conflicting evidence exists. The most common reason for revision to total hip arthroplasty(THA) from BPHA is acetabular erosion. In our study, we sought to quantify the direction of migration of the bipolar head within the first 3 years post-operatively. A proportional index in the horizontal and vertical planes of the pelvis were used to quantify migration. This method removed the need to account for magnification and rotation of the radiographs.Abstract
Introduction
Methods
Background. Since it's establishment in 2007, the National Hip Fracture Database [NHFD] has been the key driving force in improving care for hip fracture patients across the UK. It has facilitated the setting of standards to which all musculoskeletal units are held, and guides service development to optimise outcomes in this group of patients. As with any audit, the ability to draw conclusions and make recommendations for changes in practise relies on the accuracy of data collection. This project aimed to scrutinise the data submitted to the NHFD from a Major Trauma Centre [MTC], focusing on procedure coding, and discuss the implications of any inaccuracies. Method. The authors performed a retrospective analysis of all procedure coding data entered into the NHFD from July 2009 to July 2014 at Cambridge University Hospitals NHS Foundation Trust. We examined 1978 cases for discrepancies, comparing procedure codes entered into the NHFD with post-procedure imaging and operative notes. Results. The procedure coding data submitted to the NHFD was highly inaccurate, with incorrect procedure codes in 24% of the 1978 cases reviewed. In particular, coding of cemented total arthroplasty and cemented
