Numerical techniques were used to study the mechanisms of acute central cord syndrome. ⋯ Three common traumatic patterns: hyperextension, flexion, and vertical compression, could be the possibly underlying injury mechanisms of the central cervical cord syndrome according to the results of the current finite element analysis. The stress features under different injury conditions were not in complete accord. High stress mainly occurred at the posterior horn, the anterior horn, and the adjacent white matter. The centermost lesion was not common in mild central cord injuries. The upper extremity weakness should be ascribed to the damage at the corticospinal tract and the motor neurons in the anterior horn. Hyperpathia probably resulted from injuries to the posterior horn, the anterior funiculus, and the fasciculus cuneatus. Just as there are varieties of the localized stress features in central cord injuries, variations in clinical presentations were common.

A preliminary clinical study. ⋯ TTIF provides for safe interbody fusion and 270 degrees of decompression using a single posterior approach. TTIF is a useful method for reconstructing thoracic spine lesions associated with neurologic deficits.
