Embodiment Construction

[0021] A locking device for the proximal lateral femur, such as figure 1 , figure 2 and image 3 As shown, it includes a locking steel plate 1. The locking steel plate 1 includes a spoon portion 12 at the upper end and a handle portion 11 at the lower end. The spoon portion 12 at the upper end matches the shape of the greater trochanter 43 outside the proximal end of the femur of the human body, and is consistent with the greater trochanter 43 The bone surface is very tightly attached, and the handle 11 at the lower end fits the femoral body 5. The locking device also includes three trochanter locking screws 2 for extending into the trochanter 4 of the femur. The spoon portion 12 of the steel plate 1 is provided with three screw holes 13, and the three tuberosity locking screws 2 are installed in the screw holes 13 on the spoon portion 12 of the locking steel plate 1 and arranged crosswise. The trochanter 4 locking screw 2 is a cancellous bone screw. Since the three tuber...

Abstract

The invention discloses a proximal lateral femur locking device which comprises a locking steel plate, wherein the locking steel plate comprises a spoon part at the upper end and a shank part at the lower end, wherein the locking device also comprises three tuberosity locking screws used for stretching into the femoral tuberosity, and the three tuberosity locking screws are installed on the spoon part of the locking steel plate and arranged crosswise. The proximal lateral femur locking device is capable of effectively fixing the proximal lateral femur firmly without loose, thereby promoting healing of bone fracture.

Description

technical field [0001] The invention relates to an orthopedic medical instrument, in particular to a locking device for the outer side of the proximal end of the femur. Background technique [0002] Proximal femoral fractures, such as femoral neck fractures of the trochanter, intertrochanteric fractures, and subtrochanteric fractures, are common serious injuries. Especially due to the anatomical particularity of the femoral neck, once a fracture occurs, its reduction and fixation are very difficult, and fracture nonunion and avascular necrosis of the femoral head often occur, so the disability rate is also high. At present, there are many treatment methods and internal fixation devices for this serious injury, but the final results are not satisfactory. The reason is that the shear force and rotational torsional stress between the broken ends of the proximal femur fracture cannot be effectively overcome. As a result, it is difficult to maintain reduction and compression fi...
