Abstract
Background and Objectives: Intertrochanteric fractures are the most common fractures that needs surgical fixation. There are some instruments applying to fix the intertrochanteric fractures. The aim of this study was to assess the positive predict value of Tip-Apex Distance (TAD) on intertrochanteric fractures treated by (DHS, Dynamic Hip Screw).
Materials and Methods: In a single center descriptive prospective study 100 Patients with intertrochanteric fractures who were treated by DHS were evaluated. These patients assessed for their Tip-Apex Distance and rate of fixation failure.
Results: 53 male and 47 female with mean age of 76.71± 11.17 were included. 43% of subjects were in grade IV of osteoporosis, 21% in grade V and 29% in grade III. In 57% the screw was located at posterior – inferior side in 40% it was placed in central and in 3% superiorly mean of TDA was 23/5±1/83 mm. The most common complication was failure of screw.
Conclusion: Based on the findings, an intertrochanteric fracture is higher in men than woman. Most patients with intertrochanteric fractures suffered from osteoporosis. The distance between the screw head to the apex has a significant possitive association with fixation failure.
