Method and device for treatment of scaphoid fracture

Abstract

The invention provides a method and device for the treatment of scaphoid fracture in the technical field of medical treatment. The method includes the following steps that a wrist fixation base is used for fixing wrist joints to the dorsal extension position, and carpalbone-navicular bone joints are determined and labeled; a sterilized auxiliary treatment device is connected to the wrist fixationbase; a 1cm transverse incision is formed at the labeling position of the skin, subcutaneous tissue is separated until the gap of the carpalbone-navicular bone joints is reached; a bone hook hooks a navicular bone and pries the navicular bone toward the radial side, and a guide sleeve pierces the distal-pole surface of the navicular bone so as to lock the device; the angle of the guide sleeve is adjusted; the direction of the sleeve is determined through a photoscopy, and it is ensured that a guide needle can be correctly inserted inside; an anti-rotation kirschner pin is inserted along the guide needle, and the auxiliary treatment device is removed; the guide needle is inserted in the distal end of the radius through drilling, and a hollow drill is used for passing through the guide needle for drilling; a double-head compression screw passes through the guide needle and is screwed into the navicular bone; the position of the screw is determined again through photoscopy, the anti-rotation kirschner pin is pulled out, bleeding is stopped, and a wound is sutured. The method and the device ensure accurate needle insertion, and the number of the times of needle insertion and the numberof the times of photoscopy are reduced.

Description

technical field [0001] The invention belongs to the field of medical technology, in particular to a method and device for treating scaphoid fractures. Background technique [0002] Scaphoid fractures are the most common carpal fractures, accounting for 60%-70% of carpal fractures, and most of them are young adults, and most of them are low-energy sports injuries. Due to its special position, anatomical structure and blood supply, scaphoid fractures If not handled properly, the necrosis rate is higher than other fractures. [0003] The treatment of non-displaced scaphoid fractures mainly includes conservative plaster fixation and surgical treatment. Conservative treatment requires up to three months of plaster fixation, which seriously affects the quality of life of patients. It is difficult to engage in even light activities. Unacceptable, if not handled properly, there is a 5%-20% possibility of non-union; surgical treatment is divided into incision fixation and minimally ...
