INTERNAL FIXATION WITH HANSSON TWIN HOOK FOR TROCHANTERIC FRACTURES
Keywords:
TWIN HOOK, TROCHANTERIC FRACTURES, ROTATIONAL STABILITYAbstract
Hansson Twin Hook was recently developed as an alternative to the classical Dynamic Hip Screw. In the present study we aimed at presenting our results obtained by using the HTH in the treatment of trochanteric fractures. Materials and methods: Over a 2-year interval, 55 patients with trochanteric fractures were treated by reduction and internal fixation using HTH system. According to the AO fracture classification, we recorded 21 cases of 31.A1 fractures and 34 cases of 31.A2 fractures. Results: Clinical assessment at 3 months postoperatively using Merle D'Aubignier scale showed very good results in 41 (82%) patients, good in 7 (14%) patients and poor in 2 (4%) patients (two patients presented fixation failure). In these 2 patients, surgical reintervention was performed -implant removal and its replacement with a Dynamic Condylar Screw with good results at 3 months follow-up. Conclusions: Osteosynthesis with Hansson Twin Hook is a good choice in trochanteric fractures. Since it is a new developed implant, more studies are necessary for clinical validation of its value.
