Abstract
This multicentre audit assessed the total Tip Apex Distance (TAD) of sliding hip screws for intertrochanteric hip fractures in the 3 fracture hospitals in Northern Ireland (Ulster Hospital, Royal Victoria Hospital & Altnagelvin Hospital). Patient demographics and anaesthetic information was also reviewed. A sample of 140 patients with adequate screening films (39 UHD, 50 RVH & 51 Altnagelvin) were selected. The TAD was measured on AP & lateral screening films and compared to the standard of 25mm or less (total in 2 views) as recommended by Baumgaertner et al (JBJS (Am) 1995).
All 3 hospitals had an average of under 25mm (22.1, 19.9 & 19.6mm respectively) with overall average of 20.4mm, and a TAD of 25mm or less was achieved in 66.7%, 82% & 80.4% in respective hospitals (77.1% of patients overall). No patients were readmitted due to cut-out, despite 22.9% of patients having a TAD greater than 25mm. Among patients with TAD over 25mm the average TAD was 30.1mm
Demographics showed a 77.8% of patients to be female, with a slight predominance of left sided injuries. Most patients were of ASA grading 2–3. Anaesthetic method preferences varied between hospitals. Patients with TAD over 25mm were not significantly different from those with TAD of 25mm or less in age, gender, ASA or operated side.
