Proximal Femoral Nail Antirotation (PFNA) I one of the implants commonly used to stabilise subtrochanteric fractures or communited inter/pertrochanteric fractures. The aim of this project was to assess the outcome of PFNA in a busy District General Hospital. Between November 2009 to November 2012, 76 patients underwent PFNA. These patients were identified from the local hip fracture database, which is prospectively collected.

The mean age of the patients was 80.11 years (range of 26.83 to 98.53). 27 were male and 49 female. Right hip was involved in 36 cases and left hip in 40. 9 patients required revision surgery due to failure of the primary surgery. 2 patients died due to other causes. 5 out of the 9 patients who underwent revision surgery had their primary surgery performed by a trainee under consultant supervision and a consultant surgeon performed the other 4 cases. In our series failure rate was 11.8%. We conclude that although PFNA is an excellent device to fix subtrochanteric or communited intertrochanteric fractures of the proximal femur one needs to be cautious and follow the correct operative technique to avoid failures.

There has been a lot of focus on the value of anatomic tunnel placement in ACL reconstruction, and the relative merits of single and double bundle grafts. Multiple cadaveric and animal studies have compared the effects of tunnel placement and graft type on knee biomechanics. 45 patients who underwent ACL reconstruction were included into our study. Femoral tunnel position was analysed by two independent doctors using the radiographic quadrant method as described by Bernard et al., and the mean values calculated. Forty-one of these patients completed a KOOS questionnaire. The mean ratio ‘a’ was 26.57% and mean ratio ‘b’ was 30.04% as compared to 24.8% (+/− 2.2%) and 28.5% (+/− 2.5%) respectively quoted by Bernard et.al, as the ideal tunnel position. Only twenty-three of these femoral tunnels were in the anatomic range. Analysis of forty-one KOOS surveys (23 anatomic, 18 non-anatomic) revealed no significant difference in total score or subscales between the anatomic and non-anatomic groups (p= >0.05). Our study suggests that the ideal tunnel position, as described by Bernard et.al. may not be ideal and fixed.
