The aim of this study was to evaluate the effect on union results of the application of cerclage cable around the lateral femoral wall (LFW) in postoperative fracture displacement.
Patients and methods
A retrospective evaluation was made of all the cases of reverse intertrochanteric fractures over a 7-year period in a trauma center. The study included 69 fractures treated with intramedullary nailing. The age of the patients, postoperative reduction quality and complications such as mechanical failure and non-union (1.4%) were obtained from the medical records. Changes in the neck-shaft angle, the amount of LFW displacement and telescoping of proximal femoral nail antirotation blades and lag screws were measured on anteroposterior and lateral radiographs. The functional evaluation of the Harris Hip Score was recorded at the final follow-up examination.
The mean age of the patients was 56.31 years (range 18–93 years). Closed reduction was applied in 37 (53.7%) cases, open reduction in 10 (14.5%) and with cerclage cable in 22 (31.8%). Mechanical failure developed in 8 (11.5%) cases where cerclage cable was not used. In 2 of these 8 cases, open reduction was successful. In the patients where cerclage cable was applied, no mechanical failure developed and no case underwent revision surgery. In the cases where cerclage cable was not used, a significantly higher rate of telescoping was found. (p = 0.001). The application of cerclage cable was seen to significantly reduce the amount of LFW displacement (2.23 mm vs 8.86 mm) and shorten the time to partial weight bearing (p = 0.000).
In reverse intertrochanteric fractures, the application of circumferential cerclage cable with cephalomedullary nailing contributes to primary stability and accelerates mobilization. Therefore, it can be considered a good option. It reduces the risk of failure internal fixation for intertrochanteric fracture.
