Comparison of three surgical approaches for cervicothoracic spinal tuberculosis: a retrospective case–control study

Study designThis is a retrospective case–control study.ObjectivesThe surgical approaches to cervicothoracic spinal tuberculosis (CTSTB) were controversial. The aim of this research is to retrospectively compare the efficacy and feasibility of anterior-only (AO) approach, combined anterior and posterior (AP) surgeries, and posterior-only (PO) approach for the treatment of CTSTB.MethodsAO approach was undertaken in 20 patients (group A), AP fusion was carried out in 18 patients (group B), and PO surgery was performed in 21 patients (group C). Surgery duration, intraoperative blood loss, length of hospitalization, neurological status, kyphosis angle correction, loss of correction, and complications of the three groups were compared.ResultsThree surgical approaches all improved the kyphosis deformity and neurological function significantly (P < 0.05). The mean loss of correction in group A in the final follow-up was higher than in groups B and C (P < 0.05), and the difference between groups B and C was not significant (P > 0.05). The mean operation time, blood loss, and hospitalization days in group B were greater than in groups A and C. Complications were most prevalent in group A, more in group B, and the least in group C.ConclusionThe AO approach surgery should be limitedly used for severe CTSTB. The AP approach had got satisfactory clinical and radiographic outcomes, but with larger trauma and more complications, which should be reservedly performed for mild CTSTB. Compared to traditional surgery, PO surgery can significantly improve clinical results and obviously relieve postoperative complications.

Halo traction, single-segment circumferential fixation treating cervical tubercular spondylitis with kyphosis

OBJECTIVE To evaluate the clinical efficacy and feasibility of twenty patients with cervical tubercular spondylitis with kyphosis (CTSK) treated by halo traction, single-segment circumferential instrumented fusion combined anterior debridement, decompression and bone grafting. METHODS Retrospective review of data on twenty patients who suffered from CTSK admitted to our hospital between January 2007 and December 2012. All of them were performed by halo traction, single-segment circumferential instrumented fusion (anterior titanium plate and posterior pedicle or lateral mass fixation) combined anterior debridement, decompression and titanium mesh cage (TMC) filled with allograft bone particles. X-ray and computed tomographic (CT) images were used to determined sagittal balance and bone fusion. The clinical efficacy was evaluated using statistical analysis about the visual analogue scale (VAS) scores of pain, neurological status according to the Frankel classification and erythrocyte sedimentation rate (ESR), which were collected at certain time. RESULTS The average follow-up period was 34.1 ± 7.0 months (24-48 months). In the 20 cases, no obvious postoperative complications related to instrumentation and bone grafting and neurologic function was improved in various degrees. The average pretreatment ESR was 46.4 ± 21.7 mm/h, which got normal within 3 months in all patients. The average VAS on admission was 6.7 ± 1.7, which decreased to 1.6 ± 1.1 postoperatively. All patients got bony fusion within 3.4-5.5 months after surgery. The Cobb angle of 30.8 ± 10.5° on admission reduced to 2.9 ± 3.9° performed by preoperative halo traction, became to -5.1 ± 4.0° after operation and remained at -4.3 ± 3.8°, with 0.9 ± 0.7° of correction loss. CONCLUSIONS Halo traction, single-segment circumferential instrumented fusion combined anterior debridement, decompression and TMC can be an effective and safe treatment method for the treatment of cervical tubercular spondylitis with kyphosis and the preoperative halo traction should be laid on much emphasis.
