Background:Spine fractures may involve the ligamentum flavum (LF). Here, we utilized the “ligamentum flavum gap,” defined by the discontinuity of the LF at the level of a vertebral fracture, to document a vertebral fracture.Methods:Utilizing X-rays, computed tomography (CT), and magnetic resonance (MR) studies, 10 patients with type B vertebral fractures were diagnosed with the ligamentum flavum gap (LFG: discontinuity of the LF) at the fracture levels. The fractures were located in 2 patients in the cervical and 8 in the thoracolumbar spine.Results:All 10 patients with vertebral fractures had complained of axial pain. Four also showed progressive thoracic kyphosis. Notably, all demonstrated a loss of continuity in the LF at the level of fracture “ligamentum flavum gap.” T2-weighted and short tau inversion recovery (STIR) MR sagittal studies were best at locating LFG at the level of a fracture.Conclusion:Here, we identified best on sagittal T2 and STIR-weighted MR studies 10 patients for whom discontinuity of the ligamentum flavum (LFG) correlated with the location of type B vertebral fractures.
La punción ventricular transorbitaria (PTO) es una técnica rápida y sencilla aunque poco conocida. Como puede realizarse en la cama del enfermo, resulta ideal en pacientes con hidrocefalia aguda rápidamente evolutiva o con enclavamiento transtentorial inminente o reciente, en quienes el acceso expeditivo a las cavidades ventriculares puede salvarles la vida. Revisamos aquí el desarrollo histórico de la técnica desde su descripción original en 1933. Por último presentamos el caso de una paciente con hidrocefalia aguda secundaria a edema cerebeloso, en quien el empleo de la PTO dio tiempo para implementar el tratamiento definitivo. La técnica utilizada por nosotros consistió en un ingreso transpalpebral, por detrás del reborde orbitario superior y a nivel mediopupilar, con una trayectoria dirigida hacia la sutura sagital, dos a tres traveses de dedo por detrás de la sutura coronal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
