title: [Adjustable thoracic-lumbar vertebrae fixation and traction brace: development and clinical usage].
abstract: We developed an adjustable traction and fixation brace for thoracolumbar vertebrae, which is made from heat-sensitive plastics and consisted of four pieces of oppositely directed bolts serving as the elevation dropping system. The brace has strong anti-bending strength and draught force. With which, every direction of movement of the spinal column can be restrained effectively and the vertical pressure on the diseased vertebrae can be eased. The biomechanical effect of this brace is in accordance with the demand of spinal cord biomechanics. It can be used at 1-2 weeks after injury. It can be used in patients with thoracic-lumbar fracture, tumour and tuberculosis after operation. The efficacy rate of 98% was achieved in 102 patients. 31 patients with injured thoracic-lumbar vertebrae could walk and squat down without any pain and complication, and the deformity was corrected or alleviated.
