RESUMO
Patients who are victims of traumatic injuries in the spine are evaluated by radiological protocols, as recommended by Advanced Trauma Life Support (ATLS), including a computed tomography (CT) scan with the patient in the decubitus position. Spine fractures considered stable with initial nonoperative management should be further evaluated with a standard simple plain radiograph in orthostasis and/or a magnetic resonance image (MRI), to exclude any associated ligament injury and avoid neurological damage caused by occult instabilities. We present an illustrative case with an injury diagnosed through orthostasis X-ray to discuss its importance in the management of thoracolumbar fractures.
Pacientes vítimas de lesões traumáticas na coluna são avaliados por protocolos radiológicos, conforme recomendado pelo Advanced Trauma Life Support (ATLS), incluindo uma tomografia computadorizada (TC) com o paciente em decúbito. Fraturas de coluna consideradas estáveis com tratamento inicial não operatório devem ser avaliadas posteriormente com uma radiografia simples padrão em ortostase e/ou uma ressonância magnética (RM), para excluir qualquer lesão ligamentar associada e evitar danos neurológicos causados por instabilidades ocultas. Apresentamos um caso ilustrativo com uma lesão diagnosticada por meio de raio-X em ortostase para discutir sua importância no tratamento de fraturas toracolombares.
RESUMO
Introduction: Odontoid fractures correspond to 9-15% of cervical spine fractures. Atlas fracture is rare (3-13%)8. Case presentation: Male with Anderson and D´Alonzo Type II Odontoid fracture with unstable fragment treated with occipitocervical fixation with occipital plate, C2-C3 transfacet screws; Female with type E Jefferson fracture + anterolateral atloaxial dislocation, treated with occipitocervical fixation, C2-C3-C4 transfacet screws. Discussion: Anderson and D'Alonzo Type II fractures and Jefferson type E fractures are a surgical emergency due to instability and neurological deficit.
Introducción: Las fracturas odontoideas corresponden del 9-15% de las fracturas de la columna cervical. La fractura del atlas es poco común (3-13%)8. Presentación del caso: Masculino con fractura de Odontoides tipo II de Anderson y D´Alonzo con fragmento inestable tratado con fijación occipitocervical con placa occipital, tornillos transfacetarios C2-C3; Femenino con fractura de Jefferson tipo E+luxación atloaxoidea anterolateral, tratada con fijación occipitocervical, tornillos transfacetarios C2-C3-C4. Discusión: Fracturas tipo II de Anderson y D´Alonzo y fracturas de Jefferson tipo E son una urgencia quirúrgica debido a inestabilidad y déficit neurológico.
RESUMO
STUDY DESIGN: Case report. OBJECTIVE: To report the clinical and imaging findings of a patient with the extremely rare association of aneurysmal bone cyst and osteoblastoma in the cervical spine. To our knowledge, only three cases have been reported in the published literature in children under 16 years of age with this condition in the cervical spine. METHODS: The patient's history, physical examination, imaging findings, and management with a complete 4-year medical history, surgical intervention and radiological follow-up are reported. RESULTS: A 4-year 11-month-old boy was diagnosed with aneurysmal bone cyst in association of osteoblastoma and was treated with CT-guided intralesional injection calcitonin and methylprednisolone. During the course of intralesional therapy, a pathological fracture of C2 was produced. Subsequently, a widened intralesional excision and instrumented fusion from occiput to cervical spine (C0-C4) was performed. CONCLUSION: The association of aneurysmal bone cyst and osteoblastoma in spine is extremely rare. Although both are benign lesions, in the cervical location, complete removal of the tumors is challenging. Wide resection with reconstruction of the segments for stability associated with adjuvant treatment with calcitonin and corticosteroids provides a good option.
