[Application of reconstruction of lumbo-sacral internal fixation after resection of sacrum tuberculosis].

OBJECTIVE

To investigate the effects of resection of sacrum and TSRH-3 d internal fixation of the pelvis in treatment of lumbo-sacral tuberculosis.

METHODS

twenty-eight cases with lumbo-sacral tuberculosis, including 17 cases in L5 approximately S1, 11 cases in L5 approximately S2, 4 cases in L5 approximately S3, 4 cases in S(1 approximately 3)2; underwent resection of sacrum and TSRH-3 d internal fixation of the pelvis, followed by corresponding chemotherapy and radiotherapy. Follow-up was conducted for 8 approximately 48 months.

RESULTS

The short-term outcomes were satisfactory with reduced lumbosacral pain and improvement of the neurological functions to different degrees. Two cases experienced dysuria, I case cerebrospinal fluid leakage, 2 cases experienced incision infection and delayed healing, and. 1 case experienced recurrence of chondrosarcoma. The pain in the lumbo-sacral joint and the spinal nerve root was relieved obviously, No nail break, bar fracture, and loosening of screws, enlarged screw passage, lessened pelvic, and lowed L5 spine were found.

CONCLUSION

Clearing of the lumbosacral tuberculotic focus and reconstruction are effective in achieving stabilization of the lumbar vertebrae, providing significant pain relief, and preserving ambulatory capacity.
