[Hansson Twin Hook--a new implant technique in trochanteric fractures]

Hansson Hook is an implant developed in Scandinavian countries for femoral neck fractures. Due to the good results given by this technique the implant was developed in order to use it in trochanteric fractures. The hook was doubled and the implant adapted to a plate with barrel, similar with those used in compression screw technique. The new implant is named Omega 2 Hansson Twin Hook and is produced by Stryker Osteonics. In the authors' department five patients with trochanteric fractures were treated using Hansson Twin Hook. According to Evans classification, three fractures were stable and two unstable. The surgical technique is somewhat different than a common compression screw implantation: the incision is smaller, the plate is the first to be implanted, the expanding of the hooks requires special instrumentation. Patients were allowed to walk with full weight the day after the surgery. The postoperative results were very good, both immediately and three months after operation. In conclusion, the authors believe that Hansson Twin Hook is a useful implant in trochanteric fractures and offers a good rotational stability.
