Embodiment 1

[0029] A device for fixing the medial wall of an intertrochanteric fracture, comprising a steel plate 1 installed on the medial wall of the femur, the surface of the steel plate 1 is an arc surface that fits the medial wall of the femur, and the steel plate 1 includes a steel plate body 2 for fixing the steel plate 1 And the head support structure 3 for supporting the medial wall of the femur; the steel plate main body 2 and the head support structure 3 are fixed, the steel plate main body 2 is fixed to the femur by screws, and the screws on the steel plate main body 2 pass through the femur or penetrate into the femur.

[0030] The medial femoral wall support plate 1 is fixed, and the fixation effect will be more accurate than that of lag screws and steel wires commonly used in the past. The femoral trochanter can be well supported by steel 1, and the continuity of the medial femoral cortical bone is improved, which can reduce complications such as coxa varus, nail plate fract...

Embodiment 2

[0032] On the basis of Embodiment 1, several holes 4 are provided on the side of the steel plate main body 2, steel wires 5 are passed through the holes 4, and the steel wires 5 are tied to the femur.

[0033] The steel wire 5 binds the steel plate 1 and the femur together, further improving the stability of the steel plate 1 and ensuring good support of the steel plate 1 to the femur.

Embodiment 3

[0035] A device for fixing the medial wall of an intertrochanteric fracture, comprising a steel plate 1 installed on the medial wall of the femur, the surface of the steel plate 1 is an arc surface that fits the medial wall of the femur, and the steel plate 1 includes a steel plate body 2 for fixing the steel plate 1 And the head support structure 3 for supporting the medial wall of the femur; the steel plate main body 2 and the head support structure 3 are fixed, the steel plate main body 2 is fixed to the femur by screws, and the screws on the steel plate main body 2 pass through the femur or penetrate into the femur. The medial femoral wall support plate 1 is fixed, and the fixation effect will be more accurate than that of lag screws and steel wires commonly used in the past. The femoral trochanter can be well supported by steel 1, and the continuity of the medial femoral cortical bone is improved, which can reduce complications such as coxa varus, nail plate fracture, femo...

Abstract

The invention relates to the field of medical apparatus, in particular to a fixation device for medial wall of femoral intertrochanteric fracture. The technical scheme is characterized in that the fixation device for medial wall of the femoral intertrochanteric fracture includes a steel plate mounted on a medial wall of a femur, the surface of the steel plate is an arc surface fitted with the medial wall of the femur, and the steel plate comprises a steel plate body used for fixing the steel plate and a head supporting structure for supporting the medial wall of the femur; the steel plate body and the head supporting structure are fixed, the steel plate body and the femur are fixed by screw nails, the head supporting structure and the femur fracture bone block are fixed by the screw nails, and the screw nails of the steel plate body cut through the femur or rip into the femur. The fixation device for the medial wall of the femoral intertrochanteric fracture ensures the accurate position of the fracture, and solves the problem of shortening or hip varus when the femur heals.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a fixation device for the medial wall of intertrochanteric fractures. Background technique [0002] Intertrochanteric fracture, also known as intertrochanteric fracture, often occurs in the elderly and is one of the most common hip fractures in clinical practice, accounting for about 35.7% of hip fractures in domestic statistics. With the intensification of population aging, the elderly population is increasing, and the elderly are often combined with osteoporosis. Under the action of external force, they are more likely to fracture than young people, and the incidence of hip fractures continues to increase. Due to the decline in the reaction ability of the elderly and the poor protection of the hip muscles, hip fractures can occur with minor injuries. Related literature reports that intertrochanteric fractures account for up to 50% of hip fractures. Intertrochanteric fractur...
