Tibial tubercle bone fracture plate and use method thereof

Abstract

A tibial tubercle internal fixation bone fracture plate comprises a central part (1), a head part (2), side parts (3) and a tail part (4), and is characterized in that the central part (1) is matchedwith the front part of a tibial tubercle and is provided with 2.4 mm or 2.7 mm locking holes or pressurizing holes, screw holes are uniformly distributed, and locking screws or cortical bone screws can be placed in the screw holes; the upper part of the central part (1) is connected with two thin plates of the head part (2), the thin plates are parallel left and right and are respectively providedwith 2.4 mm or 2.7 mm locking holes or pressurizing holes, and locking screws or cortical bone screws can be placed in the locking holes or the pressurizing holes; the two sides of the center part (1) are each provided with two side part (3) thin plates, the thin plates on the two sides are parallel to each other up and down and are provided with 2.0 mm locking holes or 2.0 mm pressurizing holes,and locking screws or cortical bone screws can be placed in the locking holes or the pressurizing holes; and the tail end of the central part (1) is provided with three thin plates of the tail part (4), which are mutually dispersed towards the far end and are respectively provided with 2.4 mm or 2.7 mm locking holes or pressurizing holes, and locking screws or cortical bone screws can be placed in the locking holes or the pressurizing holes.

Description

Technical field [0001] The invention belongs to a medical device, and specifically relates to a tibial tubercle fracture bone plate. Background technique [0002] The tibial tubercle is a bony protuberance 3cm at the distal end of the tibial plateau. It is the front end of the proximal tibia epiphysis and participates in the growth of the proximal tibia. After the age of 18, the epiphyses of the tibial tubercle fused with the tibial shaft. When the knee joint is strongly flexed and the quadriceps muscle is violently contracted, tibial tuberosity epiphysis avulsion fractures will occur. The incidence of tibial tubercle avulsion fractures in adolescents is higher than in adults. [0003] For adult tibial tubercle avulsion fractures, most of them are caused by high-energy injuries, and the fracture fragments are often significantly displaced. The conservative treatment is not good, and surgical treatment is often required. [0004] Currently, for patients with tibial tubercle avulsio...

AI Technical Summary

Problems solved by technology

Since the tibial tuberosity is the insertion point of the patellar ligament and is an important part of the knee extension device, this part will be subjected to strong traction force during knee flexion and extension. Patients after internal fixation urgently need early functional exercise. Fixation is difficult to maintain stability, especially for comminuted tibial tubercle avulsion fractures, it is even more difficult to maintain stability, and the risk of fracture redisplacement is prone to occur
