ObjectiveTo investigate the outcome of radical debridement, reconstruction with bone autograft or allograft and plate internal fixation via the anterior approach for the treatment of cervicothoracic tuberculosis.MethodsFrom Jun. 2000 to Dec. 2010, 20 patients with cervicothoracic tuberculosis were treated by debridement and bone grafting with internal fixation via the anterior approach. They included 17 males and 3 females who ranged in age from 25 to 46 years (mean 38 years). The course of disease ranged from 3 months to 2 years (mean 12 months). The onset of the disease was chronic in all patients, with main complaints of persistent pain, and cervical stiffness and deformity accompanied with low fever,night sweating and pathologic leanness. Preoperative X-ray, CT or MRI showed that the pathologic change occurred in C7-T1 segment in 10 cases, T1 segment in 6 cases, T1-T3 segment in 3 cases,and T2-T3 segment in 1 case. The Cobb angle ranged from 25 degrees to 60 degrees (mean 35 degrees) before surgery. The Frankel classification was as follows: 2 cases at grade A, 4 cases at grade B, 7 cases at grade C, 2 cases at grade D, and 5 cases at grade E. All the patients underwent a standard cervical approach by combined partial median steotomy and transverse steotomy through the synostosis between the manubrium and body of the sternum to expose the lesion adequately. Radical debridement was performed, and then a tricortical iliac crest bone autograft or allograft was placed and secured by internal fixation to reconstruct the spinal column. The change in Cobb angle and fusion of bone grafting were reexamined by X-ray regularly. The clinical symptoms and neurological function were evaluated according to NDI (neck disability index) score and Frankel classification.ResultsThere was no injury to blood vessels, spinal cord or recurrent nerve during surgery. All patients were followed-up from 16 to 39 (mean 25) months. The tuberculosis symptoms disappeared after surgery and there was no tuberculosis recurrence,incision infection, sinus formation and internal fixation failure in any of these patients. ESR re-examination recovered normally. Bony fusion was obtained in all patients and internal fixation position was normal at 3 to 6 month postoperatively. The Cobb angle ranged from 10 degrees to 16 degrees (mean 12 degrees) and NDI was reduced from (48.2 +/- 2.9) to (22.5 +/- 3.1) at the final followed-up. Except for 2 patients at grade A showing no recovery preoperatively, the Frankel classification of the other patients raised 1.5 grade on average at the final followed-up, and the nerve function of the spinal cord recovered at different degrees: 2 at grade A, 1 at grade B, 1 at grade C, 3 at grade D, and 13 at grade E.ConclusionThe anterior approach can provide direct and safe access to the lesion. The decompression effect of the vertebral canal is significant. The structural iliac crest autograft or allograft and anterior instrumentation could work effectively to stabilize the cervicothoracic junction.
