MEAN TIP-APEX DISTANCE IN LAG SCREW CUT-OUT AFTER DYNAMIC HIP SCREW FIXATION OF HIP FRACTURE
Abstract
Background: To determine mean tip-apex distance after Dynamic Hip Screw fixation of intertrochanteric fracture. Methods: Descriptive Cross-sectional study was conducted in the Department of Orthopaedics, Hayatabad Medical Complex, Peshawar from October 2015 to September 2016 on a total 285 patients. Results: A total of 285 patients were observed. Status of TAD among 285 patients was analysed as 171 (60%) patients had TAD ranged 15 mm to 20 mm, 91(32%) patients had TAD ranged 21 mm to 25 mm, 23 (8%) patients had TAD ranged >25mm. Mean TAD was 18 mm with SD±7.45. Eight percent patients had screw cut out while 92% patients didn’t had screw cut out. Conclusion: To avoid lag screw cut out in dynamic hip screw for intertrochanteric fracture of hip the Tip apex distance must be accurate otherwise there will be cut out of lag screw.Keywords: Tip-Apex Distance; Lag Screw Cut-Out; Dynamic Hip Screw; Intertrochanteric fractureReferences
