STUDY DESIGN: A case of thoracic @entity1566 without radiographic abnormality in a skeletally mature @entity1 is reported. OBJECTIVES: To report, for the first time in the literature, a case of thoracic @entity1566 without radiographic abnormality or any @entity130 in a skeletally mature @entity1 , and to propose a unique mechanism of spinal cord traction injury resulting from associated bilateral high-energy lower @entity130 . SUMMERY OF BACKGROUND DATA: Thoracic @entity1566 without radiographic abnormality is extremely uncommon in skeletally mature @entity1 . Hyperflexion with an associated distraction force usually produces the @entity1566 , which is associated with @entity130 of the spine. In the only reported case of thoracic @entity1566 without radiographic abnormality in a skeletally mature @entity1 to date (1993), despite the absence of evidence showing @entity130 associated with @entity602 on plain radiographs and computed tomograms, the magnetic resonance image demonstrated significant injury to the posterior ligamentous structures of the spine. Thoracic @entity1566 in a skeletally mature @entity1 without associated bony and @entity130 has never before been reported. METHODS: A 17-year-old skeletally mature motorcyclist was involved in a road traffic accident and sustained @entity1230 . Clinical examination showed tenderness over L1 and L2 vertebrae with @entity1109 and motor power below L2. In addition, the @entity1 also sustained a stable pelvic @entity174 ; @entity174 of the right acetabulum; open dislocation of the right knee with complete disruption of both cruciate ligaments, the posteromedial capsule, and the medial collateral ligament; open @entity174 of the left tibia and fibula; displaced @entity174 of the medial condyle of the left femur; @entity174 of the right distal radius; and @entity174 of the right proximal humerus. The plain radiographs of the whole spine and computed tomography scanning of the thoracolumbar spine showed no evidence of @entity130 . The contemporary magnetic resonance image scanning of the entire spine showed disruption of the spinal cord from T10 downward, with patchy high signal in the cord and loss of normal architecture. After appropriate management of the associated @entity130 , the @entity1 was transferred to the regional spinal unit for rehabilitation. RESULTS: Thoracic @entity1566 in a skeletally mature @entity1 occurred in the absence of associated bony and @entity130 , and probably resulted from a longitudinal traction force transmitted through the sciatic nerves to the spinal cord as a result of associated high-energy bilateral lower @entity130 . CONCLUSIONS: A rare case of thoracic @entity1566 without radiographic abnormality manifested as a result of traction @entity1930 caused by bilateral violent lower @entity130 in a skeletally mature @entity1 is presented. To the best of the authors' knowledge, such a case has not been reported previously.
