A novel internal fixation for fixing an intracapsular fracture of a femoral neck using a minimally invasive procedure is provided. The fixation apparatus (Figure 1) includes a tubular member (12) having sharp end (16) and a blunt end (18) that is adapted to be implanted while slightly crossing the fracture line. Three lag screws (20) are adapted to pass through passages (56) in the tubular member (12) and extend outwardly beyond the sharp end (16) while threads (24) in the lag screws (2) allow for compression of bone fragments. In extracapsular and subtrochanteric fractures, the internal fixation can be incorporated with external- interlocking apparatus (100) that comprises pin screws (104) that are adapted to be inserted through bores (58) laterally provided on the tubular member (12), so as to interlock the tubular member (12), and additional pin screws (106) that are nailed to a distal bone fragment (102). A connecting member (114) is adapted to secure the pin screws together and allows reduction, correction and fixation in the intra and post-operative period. |
