Description

Thumb abduction fixation brace

technical field

The utility model relates to the technical field of medical instruments, in particular to a thumb abduction fixation brace.

Background technique

The ulnar collateral ligament (UCL) injury of the metacarpal joint (MCPJ) of the thumb accounts for about 60% of the total number of ligament injuries of fingers 1-5. It is also the most common type of injury of the thumb, often causing thumb dysfunction and affecting patients quality of life. The stabilization of the ULCL depends primarily on the adductor aponeurosis, which covers the surface of the UL and connects dorsally to the extensor tendon cap. When the ulnar collateral ligament is completely ruptured, the broken end can be retracted and shifted under the adductor aponeurosis, or can be embedded between the adductor aponeurosis, resulting in nonunion of the tendon and ligament, which is called Stener's lesion. With the avulsion and separation of the ligament, this injury will be difficult to heal and requires surgical treatment, otherwise the hypertrophic scar tissue will cause the ligament to become unstable. Partially torn or non-displaced ulnar collateral ligament injuries only need splint fixation. If there is a displacement > 2mm, surgical treatment is usually required; if the torn ligament is not displaced, or if the displacement is mild < 2mm, it is called non-displacement. Stener's disease does not require surgery. Therefore, judging the displacement or injury of the adductor aponeurosis is very important to clarify the injury and degree of the ulnar collateral ligament. MRI can accurately display the fine anatomical structure and damage of the lateral ligament of the thumb, providing a reliable basis for clinical diagnosis and treatment.

At present, in routine clinical MR scans of the metacarpophalangeal joints of the thumb, the neutral position of the thumb is often used, but the neutral position image often cannot fully clearly show the complete course structure of the adductor aponeurosis, and then accurately judge the displacement and injury of the ulnar collateral ligament Situation; In order to optimize the inspection effect and solve the problem that the examinee cannot maintain the maximum abduction position of the thumb during the inspection, and the image quality is affected by motion artifacts caused by poor braking, this patented technology applies the thumb abduction fixation brace to the thumb In the MR imaging, it can make the metacarpophalangeal joint reach the maximum abduction position, and achieve the best braking effect during the inspection process, so as to clearly display the anatomical structure and the degree of injury displacement of the adductor aponeurosis and ulnar collateral ligament, and accurately Assess for injury to the ulnar collateral ligament of the metacarpophalangeal joint of the thumb.

In view of this, the utility model is proposed.
