OBJECTIVE: The present study aimed to investigate the surgical efficacy of staged posterior-anterior combined surgery for the treatment of cervicothoracic segmental tuberculosis (TB) with kyphosis in pediatric patients. METHODS: The clinical data of 15 pediatric patients admitted to our hospital from January 2010 to December 2017 who underwent staged posterior-anterior combined surgery for cervicothoracic segmental TB with kyphosis were collected. A posterior median incision was made for patients after general anesthesia. Autologous bone particles or allogeneic bone particles were taken, trimmed, and placed in the articular eminence of the diseased vertebral body. Fifteen pediatric patients underwent second-stage lesion removal using the anterior approach. The left sternocleidomastoid muscle was selected as the medial oblique incision approach. The abscess and caseous necrotic material were removed and sent for pathological examination. The sagittal and coronal parameters (including the local Cobb angle, the sagittal vertical axis [SVA], and the coronal balance distance [CBD]) were measured at three time points: preoperatively, postoperatively, and at the final follow-up. The American Spinal Injury Association's spinal-cord injury classification, the Japanese Orthopaedic Association's (JOA) cervical spine function score, the neck disability index (NDI), and the visual analogue score (VAS) for cervicothoracic segment pain were adopted for the assessment of functional improvement and quality of life. RESULTS: All 15 pediatric patients completed the surgery successfully, with an operation duration of 3.56 ± 0.68 h, an intraoperative hemorrhage of 289.7 ± 84.3 mL, an average fixation of 7.3 ± 1.8 segments, and a follow-up duration of 28.1 ± 9.7 months. The preoperative and postoperative sagittal local Cobb angle was 67.06 ± 17.54° vs 19.48 ± 2.32° (P < 0.01), the SVA was 35.19 ± 10.69 mm vs 7.67 ± 1.40 mm (P < 0.01), and CBD was 22.58 ± 7.59 mm vs 8.99 ± 1.25 mm (P < 0.01). The levels of the postoperative erythrocyte sedimentation rate and C-reactive protein were significantly lower in all patients. The preoperative and postoperative JOA scores were 8.93 ± 3.51 and 14.67 ± 1.34, respectively, the preoperative and postoperative VAS was 7.40 ± 1.35 and 2.67 ± 0.62, respectively, and the preoperative and postoperative NDI was 32.67 ± 4.83 and 13.73 ± 2.08, respectively. There were statistically significant differences in the above indicators before and after surgery (P < 0.05). CONCLUSION: In the surgical treatment of cervicothoracic TB with kyphosis in pediatric patients, staged posterior-anterior combined surgery significantly corrects deformity, achieves the safe and effective neurological decompression of the spinal cord, and obtains good neurological recovery and bone-graft fusion according to the extent of the involved segments of kyphosis, the characteristics of the lesion, and the degree of neurospinal injury.
