A total seven cases of tuberculous spondylitis of the lumbosacral junction were treated by transperitoneal anterior vertebral interbody fusion. The postoperative course was unevenful with minimal complications in all cases. There was no evidence of recurrence of infection, low back pain, or sciatica during follow-up periods of seven to sixty months. The clinical experience gained in this study leads us to conclude that the transperitoneal approach for tuberculous spondylitis of the lumbo-sacral junction is advantageous in that, the lesion is exposed under direct vision, so adequate curettage and the bone graft can be carried out accurately and easily.
