Hybrid interlocking proximal femoral fracture fixation

摘要

The present invention provides a unique and novel internal fixation for fixing an intracapsular fracture of a femoral neck while using minimal invasive procedure. The fixation comprises a hollowed or full tubular member having a sharp end and a blunt end that is adapted to be implanted while slightly crossing the fracture line. The tubular member is provided with three passages that extend from the sharp end to the blunt end. Three lag screws are adapted to pass through the passages and extend outwardly beyond said sharp end while thread that is provided in the lag screws so as to allow compression of fragments of the bone. The lag screws are provided with screw heads so as to prevent the screws from being fully inserted into the passages and through the trochanteric cortical bone. ;The internal fixation can be incorporated into an external-interlocking fixation apparatus that comprises the tubular member laterally provided with bores on opposite sides of the tubular member wherein pin screws are adapted to be inserted through the bores so as to interlock the tubular member and additional pin screw that are nailed in a distal femoral fragment. A connecting member is adapted to secure the pin screws together so as to assure stability of the tubular member within the bone and to allow reduction, correction and fixation in the intra and post-operative period.
