Auxiliary device in the treatment of avulsion fractures of the tibial attachment of the anterior and posterior cruciate ligaments

Abstract

The invention discloses an auxiliary device for treating avulsion fractures of anterior and posterior cruciate ligament tibial attachment points, which comprises a cylindrical hollow guide sleeve, and an opening is opened along the axial direction of the guide sleeve, and the opening is connected with two ends of the guide sleeve. A disc-shaped steel plate is arranged coaxially inside, a central column is provided at the center of the bottom surface of the steel plate, a through hole a is opened on the central column, barbs are also provided on the bottom surface of the steel plate, and through holes are respectively opened at both ends of a diameter of the steel plate. hole b. It solves the problems of long time consumption, high risk of infection and difficult operation in the treatment of avulsion fractures of the tibial attachment of the anterior and posterior cruciate ligaments.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to an auxiliary device for treating avulsion fractures of tibial attachment points of anterior and posterior cruciate ligaments. Background technique [0002] Traditional methods for fixing avulsion fractures of the tibial attachment of the anterior and posterior cruciate ligaments include open reduction and internal fixation, silk and steel wire fixation, and screw internal fixation. Regardless of the fixation method, a long wound of about 20 cm is required, which will cause great damage to the joints and ligaments, take a long time, have a high risk of infection, and the fixation is unreliable. External fixation must be assisted after completion, and it will cause joint stiffness and dysfunction , seriously affecting the lives of patients. [0003] At present, doctors such as Martinez suture the avulsion fracture of the tibial insertion of the anterior and posterior cruciat...
