Initial Mechanical Stability of Three Distally Locked Intramedullary Nail Systems

Source

Both the initial torsional stability and axial compressive fixation strength were compared using human cadaver femoral specimens, for three intramedullary nail systems incorporating distal transverse locking: the Grosse-Kempf (GK), Brooker-Wills (BW), and an experimental system referred to informally as the Utah Nail (UN). Unlike the GK system, the BW and UN devices utilize internally deployed distal fixation components to provide transverse stabilization without the need for either mechanical aiming devices or distal incisions for placement of components. The experimental UN system provided greater stabilization and strength than the BW but less than the GK, especially with respect to strength. The UN system has been used successfully in a small number of clinical cases, and it is not yet clear what levels of stabilization and strength are needed in various clinical situations.
