Abstract

Purpose: The purpose of this study is to evaluate the efficacy of the trochanter reattachment device (TRD) as a firm internal fixation method for bipolar hemiarthroplasty in unstable intertrochanteric femur fracture for elderly patients over 65 years old.
Materials and Methods: From September 2010 to April 2011, 19 patients (M/F: 1/18) over 65 years old were treated with bipolar hemiarthroplasty using the TRD as a fixation method for intertrochanteric femur fracture with above Evans-Jensen classification 2nd (above AO/OTA A1.3). They were followed up for more than 12 months(12-29 months).
Results: Out of 19 patients, only one had loosening of the TRD plate and reoperation was performed. There was no dislocation after surgery. Complete fracture union was observed in 19 patients with follow up of more than 12 months.
Conclusion: In bipolar hemiarthroplasty for intertrochanteric femur fracture, TRD produced easy and firm fixation. Additional fixation with TRD restoring abduction force by union of greater trochanter can be a good choice of surgery for avoidance of dislocation and chronic pain due to trochanteric nonunion after arthroplasty.
