One-stage posterior debridement with transverse process strut as bone graft in the surgical treatment of single-segment thoracic tuberculosis: A retrospective single-center study.

ABSTRACT

This retrospective study investigated the effect of the novel bone graft transverse process strut (TPS) in single segmental thoracic spinal tuberculosis (TB) with the one-stage posterior approach of debridement, fusion, and internal instrumentation. Thirty patients treated in our department from March 2014 to October 2016 were retrospectively analyzed. Surgical time, blood loss, hospitalization time, drainage volume, and follow-up (FU) duration were recorded. The visual analog scale (VAS), Oswestry Disability Index (ODI), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), American Spinal Injury Association (ASIA) grade, segmental angle, and bone fusion were compared between preoperative and final FU. All the patients were followed for a mean 50.10 ±â€Š25.10 months; the mean age, surgical time in minutes, blood loss, hospitalization time, and drainage volume were 46.23 ±â€Š17.20 years, 195.08 ±â€Š24.0 minutes, 280.77 ±â€Š189.90 mL, 17.31 ±â€Š4.23 days, 436.92 ±â€Š193.81 mL, respectively. VAS and ODI scores were significantly improved at the final FU. The ESR and CRP returned to normal. All patients achieved bony fusion with a mean time of 5.85 ±â€Š1.82 months and a mean segmental angle of 18.77 ±â€Š2.49° preoperatively, which significantly decreased to 9.31 ±â€Š1.54° at the final FU (P < .05). No complications, such as bone graft failure, pleural effusion, fistula, or wound infection were recorded except for cerebrospinal fluid leakage (one case), water electrolyte imbalance (5 cases), superficial infection (1 case), and mild intestinal obstruction (1 case). TPS as a bone graft is reliable, safe, and effective for segmental stability reconstruction for surgical management of single-segment thoracic spinal TB.
