Abstract

The invention discloses an auxiliary device for treating front and back cruciate ligament tibial attachment point avulsion fractures. The auxiliary device comprises a cylindrical hollow guide sleeve, wherein an opening is formed in the axial direction of the guide sleeve; the opening is communicated with two ends of the guide sleeve; a disc-shaped steel plate is coaxially arranged inside the guide sleeve; a central column is arranged at the central position of the bottom surface of the steel plate; a through hole a is formed in the central column; inverted thorns are further arranged on the bottom surface of the steel plate; and through holes b are formed in two ends of one diameter of the steel plate respectively. The auxiliary device solves the problems of great time consumption, large infection risk and high operative difficulty index existing in the manner for treating front and back cruciate ligament tibial attachment point avulsion fractures.

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...
