Treatment of thoracolumbar fracture with pedicle screw system under endoscopy assisted X-tube system / 中国矫形外科杂志

ABSTRACT

[Objective]To investigate the clinical effects of the treatment of thoracolurnbar fracture with pedicle screw system under endoscopy assisted X-tube system.[Method]Twenty-one cases of pure thracolumbar fracture without neural impairment were treated with pedicle screw system under endoscopy assisted X-tube system.With the image intensifier,the pedicle based in the affected segments were localized and exposed through 4 small incisions(3cm).Transpedicular fixation and reduction by endoscopy assisted X-tube system were performed through the 4 small incisions.[Result]Twenty-one cases were followed up for 12-18 months(averaged,14 months).Radiography showed good reduction fixation of the vertebral bodies,good correction of the kyphosis deformities and good restoration of lumbar motion.[Conclusion]The treatment of thoracolumbar fracture with pedicle screw system under endoscopy assisted X-tube system is indicated for thoracolumbar fracture without neural impairment.This technique has advantages of minimal invasion and early functional recovery.
