Treatment of senile spinal tuberculosis with posterior percutaneous pedicle screw fixation combined with local percutaneous endoscopic debridement

Abstract

To explore the short-term efficacy of posterior percutaneous screw fixation combined with local percutaneous endoscopic debridement in treating senile spinal tuberculosis. The clinical data of 19 senile patients with spinal tuberculosis underwent surgical treatment from January 2015 to September 2016 were retrospectively analyzed. There were 13 males and 6 females, aged from 60 to 73 years old with an average of (66.2±4.0) years. All patients have been diagnosed with spinal tuberculosis prior to hospitalization with abscess, dead bone formation but no sinus, neurological symptoms, open surgical indications. All patients were treated with posterior percutaneous screw fixation combined with local percutaneous endoscopic debridement, and were given appropriate chemotherapy for 3 weeks preoperatively. Pre-and post-operative visual analogue score (VAS), Oswestry Disability Index (ODI), sagittal Cobb angle of lesion segment, erythrocyte sedimentation rate(ESR), C-reactive protein(CRP) were analyzed. All the 19 patients successfully completed the operation and passed through the perioperative period safely. The operation method was unchanged during the operation. The average operation time was (153.2±14.0) min. Except for 1 patients who had delayed incision healing, other patients healed at I stage within 2 weeks after operation. All patients were followed up for 15 to 26 months with an average of (19.6±3.2) months.VAS, ODI, sagittal Cobb angle of lesion segment, ESR, CRP were decreased from preoperative(5.9±1.1) points, (80.9±4.0)%, (30.8±5.5)°, (79.6±14.4) mm/h, (56.9±9.5) mg/L to(1.8±0.9) points, (66.4±5.4)%, (15.9±2.5)°, (20.4±4.6) mg/L, (32.0±8.1) mm/h at final follow-up(P<0.05). Senile spinal tuberculosis have more complications and poor general body condition. Posterior percutaneous pedicle screw fixation combined with local percutaneous endoscopic debridement in treating the patients can reduce trauma, got satisfactory effect.
