To investigate the effect of surgical treatment of lumbar spondylitis, with posterior approach to remove the lesion, bone graft between transverse process and nail rod system were applied to make internal fixation.

From February 2011 to April 2017, total of 62 cases with lumbar brucellar spondylitis were collected in the No. 1 Affiliated Hospital of Hebei North University. After surgical treatment, Visual analogue scale (VAS) was used to assess the degree of lower limb pain and lower back pain, Oswestry disability index (ODI) was used to assess the degree of recovery of waist function; Frankel spinal cord injury classification method was used to determine the recovery of spinal cord function.

No intraoperative vascular injury or spinal cord injury occurred. The incisions healed well. Postoperative follow-up was longer than one year. The infection symptoms disappeared. After 3 months, the blood sedimentation and other infection indexes returned to normal. The result of X-ray examination showed that bone healing occurred in transverse process during 3-12 month. After 3 months, 6 months and 12 months follow-up, VAS score points was (3.05 ± 0.65), (1.88 ± 0.55) and (0.31 ± 0.42), respectively, compared with preoperative points (6.67 ± 1.85), which were significantly lower, with significant difference (F= 11.21,P= 0.012). The classification of Frankel spinal cord injury was significantly better than before (Z= 2.01,P= 0.022). The ODI functional disorder index were (21.15 ± 5.35), (12.26 ± 4.55) and (5.31 ± 3.12), significantly lower than that of preoperative (37.87 ± 4.85), with significant difference (F= 9.31,P= 0.031).

For vertebral canal and nerve root canal, a complete decompression could be created by the operation. For lumbar Brucella spondylitis, long period oral therapy combined with posterior approach operation was effective.
