The efficacy of three types of internal fixation for intertrochanteric fractures

Abstract

Objective To compare the efficacy of three types of internal fixation for intertrochan-teric fractures. Methods 68 cases of intertrochanteric fracture were compared. According to Evans classification, combined with patient age and the extent and location of the fractures, 68 patients were randomly divided into groups A, B, and C, each group receiving different internal fixations. Group A of 30 patients (25 types Ⅰ and Ⅱ and 5 types Ⅲ and Ⅳ), internal fixation with DHS; group B 23 (17 types Ⅰ and Ⅱ and 6 types Ⅲ and Ⅳ ), fixation with DCS, group C (15 types Ⅲ and Ⅳ) treated with PFN. The advantages and disadvan-tages of the three procedures were assessed.Results 68 patients were followed up for 8 to 37 months, an average of 19 months and all fractures healed. According to the standard of Parker hip fracture, the efficacy was excellent in 52 patients, good in 8, fair in 6, and poor in 2; the total rate was 91.18%. Conclusions DHS and DCS are ideal for stable types Ⅰ and Ⅱ , part of type Ⅲ, and some type of intertrochanteric fracture, DCS is more suitable for intertrochanteric femoral fractures, and intertrochanteric PFN is for all types of fractures,especially types Ⅲ and Ⅳ type unstable fractures.
