Objectives: To determine whether kinds of implants would influence on the radiologic outcomes in the treatment of osteoporotic intertrochanteric fractures.

Materials and methods: In this retrospective study, radiologic outcomes of 151 patients with unstable osteoporotic intertrochanteric fractures undergoing surgical treatments were compared based on the types of fixation implants as follows: PFNA (53 cases, group 1), gamma nail 3 (31 cases, group 2), CHS with TSP (43 cases, group 3), and helical blade type LCP–DHS with TSP (24 cases, group 4). On the follow-up radiographs after operations, we assessed differences of bone union durations, neck-shaft ankle changes, lag screw or helical blade slippages, and varus α angle changes among the study groups.

Results: All the radiologic outcomes evaluated in this study were not significantly different among the study groups. The average bone union durations of the groups 1, 2, 3 and 4 were 17.7, 18.0, 18.2, and 17.8 weeks respectively (P=0.429). The average variation of neck-shaft angle of the groups 1, 2, 3 and 4 were 3.6°, 3.1°, 3.7° and 2.9° respectively (P=0.273). The average lag screw or blade slippage of the groups 1, 2, 3 and 4 were 5.1, 3.3, 3.6 and 2.7 mm respectively (P=0.154). The average variation of varus α of the groups 1, 2, 3 and 4 were 5.3°, 4.7°, 4.1° and 4.6° respectively (P=0.894).

Conclusions: This study indicates that four typical types of fixation implants for treating osteoporotic intertrochanteric fractures would not lead to differences in postoperative radiological outcomes.
