Internal fixation anti-slip locking bone fracture plate applied to femoral neck fracture

Abstract

The invention discloses an internal fixation anti-slip locking bone fracture plate applied to a femoral neck fracture. The bone fracture plate comprises a fixing part and a supporting part which are of an integrated structure, wherein the fixing part is used for being fixed to the front side of the proximal femur, the supporting part extends upwards and inwards from the fixing part and extends inthe direction of the femoral head below the femoral neck, and the supporting part is used for bearing a proximal bone structure of a femoral neck fracture line. The bone fracture plate is placed in front of the proximal femur, so that a proximal femur neck fracture line bone structure is supported below the femur neck, downward movement of the proximal bone structure of the femoral neck fracture line above the bone fracture plate caused by the gravity of a patient is effectively avoided, and the effects of supporting and avoiding sliding displacement of the femur neck fracture are achieved; and therefore, the probability of internal fixation failure of the femoral neck fracture is reduced, and the curative effect of femoral neck fracture surgery is improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an anti-slip locking bone plate for internal fixation of femoral neck fractures. Background technique [0002] Femoral neck fracture is a common type of fracture in orthopedic clinics. The traditional method of internal fixation for this kind of fracture is to use three hollow screws to penetrate the fracture line into the femoral head. However, for patients whose fracture line is close to the vertical direction, screw fixation The effect is poor, because when the patient is standing, due to the effect of his own weight, it is very easy to cause the structure near the fracture line to slide and displace along the fracture line, resulting in failure of internal fixation. During the clinical operation, the bone plate can be manually bent by the doctor to support and fix the femoral neck fracture, but this operation will prolong the operation time, increase bleeding, poor ma...

[0002] Femoral neck fracture is a common type of fracture in orthopedic clinics. The traditional method of internal fixation for this kind of fracture is to use three hollow screws to penetrate the fracture line into the femoral head. However, for patients whose fracture line is close to the vertical direction, screw fixation The effect is poor, because when the patient is standing, due to the effect of his own weight, it is very easy to cause the structure near the fracture line to slide and displace along the fracture line, resulting in failure of internal fixation

During the clinical operation, the bone plate can be manually bent by the doctor to support and fix the femoral neck fracture, but this operation will prolong the operation time, increase bleeding, poor matching between the bone plate and the fracture site, difficulty in placing the bone plate during the operation, and postoperative Risk of nail plate fracture
