Predictive Factors for Late-Onset Neurological Deficits in Patients with Posttuberculous Thoracic Kyphosis

Figure 4

A 63-year-old male with spinal tuberculosis presented with 158.5° of kyphosis (a). (b) Preoperative photograph showed obvious stoop (AIS grade B). The patients suffered from delayed paraplegia. (c) CT revealed destruction and fusion of multiple vertebrae from T7 to L1. (d) T2-weighted MRI showed compressed spinal cord in the kyphotic region. SCA was 79.2°. (e) SDR was 64.3%. (f–h) CSAR was 48.3%. (i) MVCR surgical procedure was carried out to resect the vertebrae of T8-12, with posterior pedicle screw fixation and fusion. SDR: spinal cord sagittal diameter ratio; SCA: spinal cord angle; CSAR: spinal cord cross-sectional area ratio.
