Fig. 3From: Two-stage treatment for severe spinal kyphotic deformity secondary to tuberculosis: halo-pelvic traction followed by a posterior-only approach correctionA 36-year-old female presented with numbness and weakness of both lower extremities for 2 months (ASIA C) and difficulty breathing after activity. Pulmonary function testing revealed a forced vital capacity of 0.96 L (37% of the expected value). CT revealed almost complete absence of the vertebral bodies from T5 to T12. HPT was applied for 12 weeks, and the weakness of both lower extremities was partially relieved (ASIA E). Pulmonary function testing revealed a forced vital capacity of 1.22 L (47% of the expected value). The kyphosis angle decreased from a pre-traction value of 148° to a post-traction value of 85°. Posterior fusion from T1 to L4 was performed, and the kyphosis angle was 73°Back to article page
