Description
Technical Field
The utility model relates to a fixed anterior cruciate ligament shin bone dead point tears device of taking off fracture belongs to the medical instrument field.
Background
The torn fracture of the tibial insertion point of the anterior cruciate ligament is the torn injury of the tibial insertion point of the anterior cruciate ligament caused by trauma, and belongs to the fracture in joints. Because the fracture part is the attachment point of anterior cruciate ligament at the shin bone, the fracture displacement of the torn off tibial insertion point of the anterior cruciate ligament easily causes the function loss of the anterior cruciate ligament and easily causes the fracture displacement, the function of the knee joint is seriously influenced, the improper treatment can cause the disabilities of different degrees, and a great deal of inconvenience is caused to the normal life of a patient.
Meyers, Zarciczny and the like divide the tibial avulsion fracture of the anterior cruciate ligament into three types according to the displacement degree and the crushing degree of the fracture, and the I type avulsion bone block has no obvious displacement; the II-type bone block has displacement, but part of the bone block is still involuted with the intercondylar eminence to form hinge door-opening displacement; the III type fracture block is completely separated or displaced from the tibia and can be divided into two types, namely IIIA type and IIIB type, wherein IIIA type is only the complete displacement of the simple fracture, and IIIB type is the complete displacement and the rotation of the fracture. Zarciczny defines comminuted avulsion fracture with tibial insertion shift as type IV. Conservative treatment of I-type fracture by plaster bandage fixation is advocated; in the II, III and IV fractures, the traditional knee stretching fixation can not be satisfactorily reset, so that the fracture can not be healed, the malformation can be healed and the like, thereby causing the knee stretching function of the knee joint to be limited or the joint to be unstable, and needing to be treated by operation. The fracture reduction internal fixation operation treatment under the arthroscope is a main method for treating the fracture of the cut off tibia of the anterior cruciate ligament by tearing, and the existing implants used under the arthroscope have many types and can be roughly divided into three major types: screw fixation, suture fixation, and steel wire fixation. This method is limited when the screw fixation is applied to comminuted fractures or bone fragments that are small, requiring a secondary operation to remove the screws, which increases trauma and economic burden. The suture fixation has high technical requirement, long operation time, small suture contact surface, unstable fixation and easy tilting or overturning of fracture blocks. The steel wire has small fixed contact area and concentrated acting force, ligament attachment points are easy to tear off, or fracture blocks are easy to warp or turn over, the steel wire needs to be taken out in a secondary operation, and the trauma and the economic burden are increased.
