RESUMO
Traumatic spondyloptosis is a serious injury usually caused by high-energy trauma; It consists of the anterior or posterior dislocation of 100% or more of the underlying vertebral body, which can become a total injury of the spinal cord, producing a neurological deficit; this type of injury represents stage 4 and 5 of Allen-Ferguson. Clinical case: A 50-year-old man who suffers a car accident, he receive frontal impact when he was a driver, colliding with the retaining wall, referred from another hospital to emergency room, managed with C7 hemicorpectomy, c7-t1 discectomy, spondylodesis with anterior plate (C6-T1), and posterior approach + Fascetectomies of C7-T1, facet joint screws C6 and transpedicular fixation of T1. Discussion: Subaxial cervical spondyloptosis is relatively rare clinical entity, a complete clinical examination is important in diagnosis, taking in considerations the injury mechanism. For treatment we have a multiple options, at this case anterior-posterior (360 degrees) treatment it was the better option for Us; however, must be personalized and consider the early rehabilitation of patient.
La espondiloptosis traumática es una lesión muy rara y grave generalmente causada por traumatismos de alta energía. Consiste en la dislocación anterior o posterior de 100% o más al cuerpo vertebral subyacente, lo que puede generar compresión y lesión total de la médula espinal, produciendo déficit neurológico; este tipo de lesión representa la etapa 4 y 5 de Allen. Caso clínico: Masculino de 50 años quien sufre accidente automovilístico al colisionar contra muro de contención, generándose lesión de tipo hiperextensión-compresión cervicotorácica, manejado con hemicorpectomía C7, discectomía C7-T1, espondilodesis con placa anterior (C6-C7, C7-T1), toma y aplicación de injerto, abordaje posterior + fascetectomías de C7 + fijación transfacetaria C6 y transpedicular de T1. Discusión: Encontramos que la estabilización temprana con pinza de Gardner más el abordaje anterior y posterior brindan adecuados resultados en cuanto a integridad sensitiva y motora del paciente así como una pronta rehabilitación.

INTRODUCTION: Multiple cervical spine fractures are a relatively infrequent entity and thus the available information on them is scarce worldwide. The cases reported are usually managed conservatively, with a combination of skeletal traction and various braces, with variable results. There are only a few reports of multiple fractures treated surgically. Objective: This is a report of a clinical case of a multiple cervical fracture treated surgically in 2 stages at the Mexico City Center for Patients with Spine and Spinal Cord Injury (Centro de Atenci6n a Lesionados Raquimedulares de la Ciudad de Mexico), located at "La Villa" General Hospital, SSDF. MATERIAL AND METHODS: We report the clinical case of a male, 46 year-old patient involved in a motor vehicle accident who sustained spine and spinal cord injuries consisting of ASIA C C2-C6 fractures. It was decided to perform two-stage surgery with posterior and anterior instrumentation. We report the 19-month clinical and radiological follow-up. RESULTS: In the 19-month follow-up visit, the patient was found to be ASIA D according to the neurological assessment, with mild motor deficit of the left thoracic limb. The patient had returned to his usual job and had acceptable cervical spine mobility. CONCLUSIONS: The patient's appropriate course from the neurological perspective and his return to his daily activities leads to recommending the surgical management of multiple fractures, customizing it in each case according to the fractures' characteristics. Favorable results may be expected from this approach.

BACKGROUND: Knowledge of the morphometric anatomy of cervical pedicles is essential for the safe and accurate placement of pedicle screws during instrumentation of the cervical spine. Screw placement in the lumbar and thoracic vertebrae is considered as a safe practice, unlike the cervical vertebrae due to the risks involved. There are few reports on this technique. The little available information comes from populations different from the Mexican population. Knowing the measurements of each cervical vertebra will provide proper screw orientation and selection at the time of screw placement. METHODS: Prospective, cross-sectional, descriptive study in subjects who presented at the outpatient and emergency services. Patient's in whom a CAT scan of the cervical spine was ordered as part of the work-up protocol, from April 1st 2010 to October 31st 2010, were included. A morphometric anatomic study was undertaken using the CAT software. In a saggital view: a) Saggital angle, b) Saggital diameter. In an axial view: a) Work distance, b) Cross-sectional angle and c) Cross-sectional diameter. RESULTS: The following measurements were obtained for each segment from C2 to C7: mean, standard deviation, range and minimal and maximal values. CONCLUSIONS AND CLINICAL RELEVANCE: Appropriate preoperative planning prior to cervical transpedicular instrumentation is essential to achieve greater accuracy during screw placement. The information obtained allows performing the procedure. As a result of this, a report based on out center's experience may be disseminated thus sharing our technique with the medical community.
