Anterior approach operation of thoracolumbar fractures through limited incision / 中国矫形外科杂志

[Objective]To investigate the surgical method and clinical effects of the anterior approach operation in the treatment of thoraco-lumbar vertebral fractures through limited incision.[Method]Thirty-four cases of bursting fracture of thoracolumbar vertebral body were treated with the operation of anterior decompression,bone grafting and internal fixation by the anterior retropleuro-peritoneum approach.The MRI combined with clinical examination,X-ray,CT results were taken as selection criteria of treatment.[Result]Thirty-four cases were treated with this operative technich.Hemorrhage capacity is about 300-800ml with average 600ml.The operation time was 2-2.5 hours.All patients were followed-up with an average period of 18 months(ranged,6-24months).No aggravation of nerve injury appeared in 34 cases.X-ray manifested good fusion,no broken nails and no recurrence of kyphosis was found in all cases.[Conclusion]Anterior approach operation through limited incision is an effective way for severe thoracolumbar fractures. It has significantly low complication and allow early recovery of function.

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

[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.
