Comparison of treatment of unstable intertrochanteric fracture with different arthroplasty methods

BACKGROUND: Intertrochanteric femur fractures are elderly is very common and can be treated by different fixation methods such as internal fixation and arthroplasty. In our study, we investigated the correlation between the hemiarthroplasty treatment method and functional results. MATERIALS AND METHODS: The study consists of 121 patients with intertrochanteric fractures and these patients are divided into three groups. Eighty-five were male and 36 were female. Group I was uncemented bipolar hemiarthroplasty patients, Group II was cemented bipolar hemiarthroplasty and Group III was cemented calcar preserving bipolar hemiarthroplasty. Mean follow-up period was 16 months. Harris hip score was used to evaluate functional outcome of the patients. RESULTS: There were no significant differences between three groups when comparing the mortality rate in the 1(st) month and 1(st) year but all time mortality was proportionally lower in Group I comparing to the two other groups. There were no significant differences between three groups when comparing the functional results in 1(st) month and 1(st) year. CONCLUSION: In our study, uncemented bipolar hemiarthroplasty is a preferable treatment over the two other arthroplasty treatment model (cemented bipolar and calcar preserving) regarding to the mortality rate since there is no significant difference between. This conclusion needs further studies with greater number of patients.
