Objective:
To explore the effectiveness of stage I anterior approach debridement and autologous iliac crest graft with single self-locked titanium plate internal fixation for the treatment of lumbosacral tuberculosis.
Methods:
Seven cases of lumbosacral tuberculosis were treated by stage I anterior approach debridement, autologous iliac crest graft, and single self-locked titanium plate internal fixation between February 2010 and October 2014. There were 5 males and 2 females, aged 18-65 years (mean, 41.6 years). The disease duration was 5-21 months (mean, 8 months). The patients had signs and symptoms of pain in lumbosacral region, radiating pain in unilateral lower limb or bilateral lower limbs, decreased muscular strength and disorders of superficial sensation. According to Frankel classification for spinal injury, 1 case was rated as grade C, 3 cases as grade D, and 3 cases as grade E. Preoperative imaging examination suggested L5, S1 lesions in line with the manifestations of tuberculosis; the lumbosacral angle was 16.4-28.5° (mean, 18.6°). The erythrocyte sedimentation rate was 28-105 mm/1 hour (mean, 61 mm/1 hour). All patients received 4-drug antituberculosis therapy.
Results:
All patients underwent the operation successfully and all incisions healed at stage I, without relevant complication. All patients were followed up 14-70 months (mean, 25.6 months). All symptoms of tuberculosis disappeared and the erythrocyte sedimentation rate returned to normal. At last follow-up, Frankel classification was returned to E from D in 3 cases, returned to D from C in 1 case. Two cases suffered from pains in the lumbosacral region and at the donor site, 1 case suffered from upper abdominal discomfort and poor appetite,but these symptoms disappeared after symptomatic treatment. At last follow-up, X-ray examination indicated that the lumbosacral angle was 23.4-34.2° (mean, 28.6°). According to Bridwell criteria, 5 cases gained grade I bone fusion, and 2 cases gained grade II bone fusion, without migration of bone graft, or loosening or breakage of titanium plate or bolt.
Conclusions:
Stage I anterior approach debridement and autologous iliac crest graft with single self-locked titanium plate internal fixation is safe and effective in treating lumbosacral tuberculosis. It can achieve good bone fusion and stable lumbosacral stability, and maintain good deformity correction.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
