摘要
Background: Human spinal curvature, hip and knee extension, arch, and dynamic muscle systemsforma unique sagittal shape and position relationship. Normal human sagittal curve enables the body in the most stable and minimum energy consumption state. Adult spinal tuberculosis had younger age of onset with a majority of vertebral tuberculosis. The most common deformity of vertebral tuberculosis iskyphosis. The body sagittal had morphological changes when tuberculous spondylitis kyphosis occurs. This study aims to understand the compensatory characteristics of sagittal morphology for angular kyphosis in adult patients with spinal tuberculosis. Methods: Adult patients with spinal TB were recruited and the following parameters were measured: Cobbangle, cervical lordosis (CL), thoracic kyphosis (TK), lumbar lordosis (LL), pelvic incidence (PI), sacral slope (SS), pelvic tilt (PT), and sagittal vertical axis (SVA). Results: Compared with normal values reported in the literature, more LL and less TK were achieved. The values of CL, PI, PT, and SS were not statistically different from that reported in the literature. The LL value was greater than the normal value reported (P<0.05). The TK value was less than the normal value reported (P<0.05). The values of CL, PI, PT, and SS showed no statistical difference compared to the normal values reported. Conclusion: Patients having angular kyphosis but sagittally compensated with normal SVA demonstrate a TK decrease, LL increase, and hyperextension of adjacent segments of the kyphotic spine, without pelvic compensation. Decompensated patients with positive SVA have characteristic pelvic retroversion, while patients with negative SVA have increased pelvic anteversion.
