A Bennett fracture reduction and fixation frame

Abstract

A Bennett fracture reduction and fixation frame and its application method. A Bennett's fracture reduction and fixation frame capable of maintaining stability after reduction in the recovery process of Bennett's fracture and its application method are proposed. The body of the fixed frame includes a forearm fixed frame and a forearm hook and loop. The forearm fixed frame has a concave arc surface that conforms to the palm side surface of the forearm of the human body. The body of the fixed frame also includes a wrist fixed frame arranged at the front end of the forearm fixed frame. The fixation frame is provided with a hook and loop belt for the wrist joint; the first metacarpal bone fixation frame is provided in the direction of the wrist fixation frame toward the first metacarpal bone of the human body; piece; the first metacarpal bone fixing frame is provided with a dorsal compression piece at the base of the first metacarpal bone toward the back of the first metacarpal bone of the human body. After reduction, the present invention realizes pressurization and fixation for maintaining traction through pressurization of the fracture end and traction of the distal end, keeps the continuous stability of the fracture end, and creates conditions for the healing of the fracture end.

Description

technical field [0001] The invention belongs to the technical field of medical care devices, and in particular relates to a non-surgical fixation device for the reduction and fixation treatment of Bennett fractures and a method for using the same. Background technique [0002] Bennett's fracture is a fracture of the base of the first metacarpal bone, combined with dislocation or subluxation of the first metacarpal joint. It was first described by Bennett in 1882. It is a common fracture of the hand. It is easy to reduce but difficult to maintain reduction and fixation. , Displacement often occurs in the later stage, causing joint pain, stiffness, deformity, and affecting the function of the hand. [0003] Bennett's fracture is characterized by an oblique fracture of the base of the first metacarpal 512, the fracture line passes through the joint, and forms a triangular fragment 510 on the medial base of the metacarpal, retained in place by the connection of the volar ligamen...

Problems solved by technology

[0007] At present, in addition to surgery, duckbill-type wire racks are also used. However, we have found in actual use that due to the forced compression positioning method, rigid pressure needs to be maintained for a long time on the hand, and pressure sores are prone to occur even if the lining is lined with cotton pads.

Difficulty maintaining stability after reduction due to lack of traction on the thumb
