Abstract

The invention belongs to the technical field of medical apparatuses and instruments, discloses an intertrochanteric fracture outer side wall steel plate fixing device and aims to solve the problem that a fixing effect of an existing intertrochanteric fracture outer side wall fixing device is not definite. The intertrochanteric fracture outer side wall steel plate fixing device comprises a steel plate body, wherein the steel plate body comprises a steel-plate upper section and a steel-plate lower section, the steel-plate upper section is mutually fit with the outer side wall of a thigh-bone upper section in shape, at least one claw-shaped structure mutually fit with the upper end of the femoral great trochanter is arranged at the upper end of the steel-plate upper section, and multiple threaded holes for installing screws are formed in the steel-plate lower section. The intertrochanteric fracture outer side wall steel plate fixing device can improve the stability and accuracy of fracture block fixing and prevent fracture block displacement.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a steel plate fixing device for the lateral wall of an intertrochanteric fracture of the femur. Background technique [0002] Intertrochanteric fractures, also known as intertrochanteric fractures, often occur in the elderly and are one of the most common clinical hip fractures, accounting for about 35.7% of hip fractures in domestic statistics. With the aging of the population, the elderly population is increasing, and the elderly are often combined with osteoporosis. Under the action of external forces, they are more prone to fractures than young people. The incidence of hip fractures continues to increase. The protection is poor, and minor injuries can cause hip fractures. Relevant literature reports that intertrochanteric fractures account for up to 50% of hip fractures. Intertrochanteric fractures of the femur are common in the elderly. The femoral tube...
