Spinal brucellosis is a less commonly reported infectious spinal pathology. There are few reports regarding the surgical treatment of spinal brucellosis in existing literature. This retrospective study was conducted to determine the effectiveness of single-stage transforaminal decompression, debridement, interbody fusion, and posterior instrumentation for lumbosacral spinal brucellosis.

The purpose of this study is to determine the efficacy and safety of Smith-Petersen osteotomy combined with anterior debridement and allogenic strut bone grafting for the treatment of active thoracic and lumbar spinal tuberculosis with kyphotic deformity in young children.Spinal tuberculosis is more destructive in young children and often causes severe kyphosis and paraplegia. Despite much progress has been made, surgical treatment is still controversial and technically challenging.From October 2010 to August 2014, 25 children (11 males, 14 females; aged under 6 years) with active thoracic and lumbar spinal tuberculosis treated by Smith-Petersen osteotomy combined with anterior debridement and allogenic strut bone grafting were enrolled in this study. The pre- and postoperative data, follow-up medical records, imaging studies, and laboratory data were collected prospectively. Clinical outcomes were evaluated on the basis of kyphotic angle and the Frankel motor score system. The changes in C-reactive protein (CRP) levels, erythrocyte sedimentation rate (ESR), clinical symptoms, and complications were investigated. Graft fusion was evaluated using the Bridwell grading criteria.The mean age was 3.5 ± 1.76 years (range, 1-6 years). All patients were followed up for 25 to 45 months (average, 34.3 ± 5.86 months). The average kyphotic angle was changed significantly from a preoperative value of 44.1 ± 10.8° to a postoperative value of 11.4 ± 3.9°, with an average correction rate of 74% (P < .05). According to the Frankle motor score system, neurological deficits were significantly improved by the time of the last follow-up, with an average improvement of 1.7 grades (P < .05). There were 2 cases of rod breakage and 1 case of graft bone displacement. No patients experienced a recurrence of tuberculosis. According to Bridwell criteria, the degree of fusion was grade I in 23 patients and grade II in 2 patients with a fusion rate of 92%.For young children with active thoracic and lumbar spinal tuberculosis, Smith-Petersen osteotomy combined with anterior debridement and allogenic strut bone grafting is a safe and simple procedure to achieve sufficient kyphosis correction, good neurological recovery, and reliable anterior column reconstruction.

 To discuss the surgical treatment and its effectiveness of odontoid fracture complicated with atlantoaxial dislocation in children with spinal cord injury.  From January 2010 to December 2014, 10 cases of children under 14 years old, with intractable odontoid fracture with atlantoaxial dislocation were enrolled. The mean duration between injury and admission was 8.5 d (range 1-30 d). The surgery was performed using posterior reduction and internal fixation or anterior release combined with posterior fixation. The medical date including preoperative and postoperative neurological function, degree of reduction and fusion.  All cases were followed-up for 12-48 months. The last follow-up X ray and CT examinations showed good reduction and fusion. No fixation failure was observed among all the patients. According to the Frankel, the preoperative neurological function was C in 2 cases, D in 4 cases, and E in 4 cases. At the last follow-up, out of 2 cases with Frankel C improved to D, and the other 8 cases were back to normal.  Diagnosis of odontoid fracture complicated with atlantoaxial dislocation is usually delayed in children. One-stage posterior reduction and internal fixation or anterior release combined with posterior fixation is an effective and safe surgical procedure for such cases.

Brucellar spondylodiscitis, the most prevalent and significant osteoarticular presentation of human Brucellosis, is difficult to diagnose and usually yields irreversible neurologic deficits and spinal deformities. However, no animal models of Brucellar spondylodiscitis exist, allowing for preclinical investigations. The present study investigated whether intraosseous injection of attenuated  vaccine into rabbits' lumbar vertebrae imitates the radiographic and histopathological characteristics of human Brucellar spondylodiscitis. Radiographic and histopathological analyses at 8 weeks postoperatively revealed radiographic changes within vertebral bodies and intervertebral discs, abscesses formation within the paravertebral soft tissue, and typical prominent inflammation response without caseous necrosis, which were largely comparable to human Brucellar spondylodiscitis. Such a medium-sized, surgically feasible rabbit model provides a promising  setting for further preclinical investigation of Brucellar spondylodiscitis.

Establishment and Initial Testing of a Medium-Sized, Surgically Feasible Animal Model for Brucellar Spondylodiscitis: A Preliminary Study.

BACKGROUND This study aimed to investigate the safety and clinical efficacy of 3 different surgical methods for treating spinal tuberculosis (ST) in children. MATERIAL AND METHODS We reviewed the cases of 62 children with ST who were treated in our hospital from January 2010 to December 2014. In this study, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) level, Frankel classification of neurological function, pain visual analog scale (VAS) score, and kyphosis Cobb (k-Cobb) angle were dynamically monitored to evaluate the efficacy of different surgical methods. Complications in the patients were evaluated at 3 time points: before surgery (T1), after surgery (T2), and during final follow-up (T3). The average follow-up was 27.4 months. Twenty-two patients underwent simple anterior debridement alone or combined with internal fixation (Method A), 13 patients underwent posterior debridement alone (Method B), and 27 patients received anteroposterior debridement and bone graft fusion together with internal fixation (Method C). RESULTS In all 3 groups after surgery, ESR, CRP levels, VAS scores, and k-Cobb angles significantly decreased. However, compared with patients who received Methods B and C, patients who received Method A had a significant rebound in k-Cobb angle and a higher incidence of complications at the T3 time point. The overall reoperation rate during follow-up was 37.10%. Fourteen patients (22.58%) had kyphosis, 2 patients (3.23%) had tuberculosis recurrence combined with kyphosis, and other complications were reported in 5 patients (8.06%). CONCLUSIONS Considering the incidence of complications and level of postoperative biochemical indicators, we concluded that caution should be exercised in using an anterior approach to treat pediatric ST.
