Analysis of Nanohydroxyapatite/Polyamide-66 Cage, Titanium Mesh, and Iliac Crest in Spinal Reconstruction of the Patients with Thoracic and Lumbar Tuberculosis.

The follow-up outcomes showed that the method involving one-stage posterior debridement and internal fixation, interbody graft, and fusion is an effective and safe surgical method for patients with thoracic and lumbar tuberculosis. The incidence rate of cage subsidence was less and the bone graft fusion time was shorter with nanohydroxyap atite/polyamide 66 cage when compared with iliac bone graft and titanium mesh bone graft in the surgical treatment of thoracic and lumbar tuberculosis. Nanohydroxyapatite/polyamide-66 cage has a promising application prospect to be a new bone graft material.
