Lumbar spondylolysis brace and manufacturing method thereof

Abstract

The invention discloses a lumbar spondylolysis brace. The lumbar spondylolysis brace comprises a main body and connecting bands; a plurality of circular through holes are formed in the front surface and the side surface of the main body; the middle part of the back surface of the main body is hollow, and the upper end and the lower end of the back surface of the main body are open and are providedwith the connecting bands; a crista iliaca arc is arranged in the middle of the main body; the main body comprises a first brace part and a second brace part; and the first brace part used for fixinglumbar vertebra is arranged above the crista iliaca arc of the main body, and the second brace part used for fixing ilium is arranged below the crista iliaca arc of the main body. In the invention, the lumbar spondylolysis brace is customized, and is manufactured according to the size of a plaster model through plaster mold taking in advance. Compared with existing lumbar vertebra common braces,the lumbar spondylolysis brace can fix the ilium and control lumbosacral flexion, extension and rotary movement at the same time, facilitates isthmus healing, fits the body shape of a patient, and generates better wearing experience of the patient.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a lumbar isthmus brace and a manufacturing method thereof. Background technique [0002] Lumbar spondylolysis: The fully grown lumbar spine of the human body can be divided into vertebral body, vertebral arch, lamina, upper and lower articular processes, transverse process and spinous process. The narrower part between the upper and lower articular processes is called the isthmus. If the bone is discontinuous on one or both sides of the isthmus, it is called lumbar spondylolysis. Brace: An external fixation placed on the outside of the body, designed to limit a certain movement of the body, thereby assisting the effect of surgical treatment, or directly used for non-surgical treatment. [0003] The main cause of lumbar spondylolysis is due to fatigue and fracture of the lumbar isthmus. Domestic and foreign literature studies have shown that repeated lumbar hyperexten...

AI Technical Summary

Problems solved by technology

However, clinically, the lumbar braces used by patients with conservative and postoperative lumbar spondylolysis are ordinary braces, which are mainly suitable for all patients undergoing lumbar fusion surgery. The disadvantages for postoperative patients with lumbar spondylolysis include: 1. The iliac crest is not stable, and the control of rotation and extension is poor; 2. The isthmic fissure often occurs at the 5th lumbar segment, and the range of ordinary braces to the caudal side is not enough, resulting in increased stress on the 5th lumbar area, which is not conducive to stability and healing

3. It does not fit well with the patient's body shape; the above situation eventually leads to, on the one hand, the patient's postoperative wearing experience is poor, and he is even unwilling to wear the brace; This will lead to conservative treatment of isthmus nonunion, or postoperative isthmus bone delayed union, nonunion, and even increase the probability of loosening and fracture of internal fixation devices, bringing avoidable pain and economic burden to patients
