Internally fixed orthotics of growing-stage scoliosis

Abstract

Provided is an internally fixed orthotics of growing-stage scoliosis. An orthopedic rod (10) of the internally fixed orthotics is provided with a near-end portion (12), a center portion (14) and a far-end portion (16), wherein a rod body at the near-end portion and the far-end portion thins gradually. Two fixed pedicle screws (24) are fixed in the center portion at intervals. A near-end positioning pedicle screw (22) comprises a near-end implanted nail (222) and a first sliding nut (224) which is provided with a first cone (226), and a first top ball (228) is embedded in the tip of the first cone and butts against the near-end portion. A far-end positioning pedicle screw (26) comprises a far-end implanted nail (262) and a second sliding nut (264) which is provided with a second cone (266), and a second top ball (268) is embedded in the tip of the second cone and butts against the far-end portion. The internally fixed orthotics can promote posterior interbody fusion in a top vertebral area and enables a scoliosis area to automatically correct along with growth of the spine.

Description

technical field [0001] The invention relates to a scoliosis internal fixation orthosis, in particular to a scoliosis internal fixation orthosis aimed at children or teenagers in the growing period. Background technique [0002] At present, for children with early-onset scoliosis, in order to preserve their spine growth and thoracic development potential, growth valve internal fixation orthopedic surgery is generally used for treatment, but the above-mentioned treatment method needs to be adjusted every six months to one year to expand the growth rod Surgery to accommodate the growth and development of the spine and thorax. However, multiple operations will significantly increase the risk of surgery and treatment costs for children. At the same time, the subperiosteal dissection of the center of the scoliosis during the multiple internal fixation adjustment operations significantly increases the risk of spontaneous fusion of the posterior structure of the center of the scolio...

Problems solved by technology

[0002] At present, for children with early-onset scoliosis, in order to preserve their spine growth and thoracic development potential, growth valve internal fixation orthopedic surgery is generally used for treatment, but the above treatment methods need to be adjusted every six months to one year to expand the growth rods. Surgery to accommodate growth and development of the spine and thorax

However, multiple operations will significantly increase the risk of surgery and treatment costs for children. At the same time, the subperiosteal dissection of the center of the scoliosis during multiple internal fixation adjustment operations significantly increases the risk of spontaneous fusion of the posterior structure of the center of the scoliosis. possible

[0003] In addition, the occurrence of vertebral body deformities in the apical vertebra area is complex, and the development of deformities is one of the important reasons for the progressive aggravation of scoliosis. Therefore, early fusion of the vertebral bodies in the apical vertebra area is beneficial to the correction of spinal deformities. There is no method or device in the art that can effectively intervene in the vertebral body in the apical region
