The specific embodiment
Below in conjunction with accompanying drawing, this utility model fracture of femoral neck locking steel plate fixing head is described in further detail.
As shown in Figure 1 and Figure 2, this utility model fracture of femoral neck locking steel plate, have six hole compositions, be lock hole, 11 centimetres of steel plate 1 length, wide 1.8 centimetres, thick 0.5 centimetre, steel plate 1 top is curved, matches with the anatomical structure of near end of thighbone, and wherein the effect of the femoral shaft fixing hole screw 3 in two of bottom femoral shaft fixing holes 2 is that steel plate 1 is fixed on to femoral shaft.Upper fixing hole screw 10 in the upper fixing hole 9 on top is to be 90 ° with steel plate 1 longitudinal axis, directly be fixed in femoral head, two adjustment hole screw 8 directions become hexagonal angle with the femur longitudinal axis, parallel with the neck of femur longitudinal axis, wherein adjustment hole 6 is made up of two combined holes 7, is lock hole, is convenient to the position of upper and lower adjustment screw, bigelow's septum fixing hole screw 5 and the femur longitudinal axis of bigelow's septum fixing hole 4 are 140 ° of angles, are slightly larger than 135 ° of average collodiaphyseal angles.Femoral shaft fixing hole screw 3 is the full thread cortical bone lock screw of 4.5 millimeters of ￠, upper fixing hole screw 10, adjustment hole screw 8 and bigelow's septum fixing hole screw 5 are the full thread hollow lock screw of 7.0 millimeters of ￠, adjustment hole screw 8 is separately joined ￠ 6.5 half-thread spongy bone cannulated screws in addition, can help the reduction of the fracture.
