Treatment of thoraco-lumbar spinal tuberculosis with kyphotic deformity with surgical techniques of Z-plate-Ⅱ~(TM) internal fixation apparatus system / 中国矫形外科杂志

ABSTRACT

[Objective]To evaluate the short-term and long-term effectiveness of the surgical technique of one-stage one-step surgical techniques of Z-plate-Ⅱ~(TM) internal fixation apparatus system and anterior debridement and autograft bone graft fusion in the treatment thoraco-lumbar spinal tuberculosis with kyphotic deformity.[Method]The outcome of sixty eight cases suffered from thoraco-lumbar spinal tuberculasis with kyphotic deformity between July 1998 and March 2004 managed by the surgical techniques of Z-plate-Ⅱ~(TM) internal fixation apparatus system and anterior debridement and antograft bone graft fusion through posteroiateral costotransversectomy or kidney incision was analyzed.All cases wer given a longitudinal study follow-up for a mean of 3.3(2.2~6.3)years postoperatively.[Result]All patients showed successful autograft bone graft fusion.Among 45 cases accompanied with neurotic symptom of Potts paraplegia,25 were completely recovered,15 were partly recovered,total the ratio of recovery was 88.89% at the end of postoperative follow-up.The average immediate postoperative correction of kyphosis angle was 28.9?,the average loss of correction was only 2.7? at final follow-up.[Conclusion]The surgical technique of one-stage one-step Z-plate-Ⅱ~(TM) internal fixation apparatus system and anterior debrideraent and autograft bone graft fusion is found helpful in strengthening the stability of the spine in thoraco-lumbar spinal tuberculosis with kyphotic deformity,providing successful interbody fusion and recovery of Potts paraplegia,correcting the kyphosis,and preventing progress of kyphosis.
