Morphometry of Pedicle and Vertebral Body in a Mexican Population by CT and Fluroscopy
Provedor de dados: 77
Autores: Urrutia Vega,Edgar; Elizondo Omaña,Rodrigo E; De la Garza Castro,Oscar; Guzmán López,Santos.
It is necessary to have precise anatomical knowledge of lumbar pedicles for the safe placement of screws. There are not reports about the morphometry of lumbar pedicles in a Mexican population exist. A descriptive, observational and cross-sectional study was done in 60 cadavers from the dissection lab of the Human Anatomy Department of the Medicine School. The aim of the study was to quantify the morphometric characteristics of the pedicles of the lumbar spine in a Mexican population. A total of 60 cadavers were evaluated by fluoroscopy and CT from L1 to L5, in the age range of 40 to 78 years. Each vertebral pedicle was measured in the axial, sagittal and coronal planes. The measurements included the minimum pedicle width, the pedicle angle, the distance...

La arteria radial (AR) es utilizada en la práctica médica para la realización de diversos procedimientos quirúrgicos, entre los que destaca la cirugía de revascularización miocárdica. En la literatura actual hay poca información acerca de la compatibilidad de esta arteria con otros conductos vasculares. El objetivo fue determinar las características anatómicas, morfométricas y distribución de la arteria radial en el antebrazo. Se disecó la arteria radial de 10 antebrazos de cadáveres embalsamados; se identificaron y registraron los ramos musculares y vasa nervorum emitidos por la arteria, se midió la longitud total y obtuvieron tres muestras (proximal, media y distal) de cada una para ser procesadas mediante técnicas histológicas y se determinaron los...

A Morphometric Study of the Extraocular Muscles
Provedor de dados: 77
Autores: Villarreal-Silva,Eliud Enrique; Hinojosa Amaya,José Miguel; Bazaldua Cruz,Juan José; Martínez Fernández,David; Elizondo-Omaña,Rodrigo Enrique; Guzmán López,Santos.
Extraocular muscles are important references in strabismus surgery and in placement of intraorbital devices. We analyzed extraocular muscles morphometry and possible anatomical variances of 20 orbits. We report the length, width, and points of insertion of the extraocular muscles. No anatomical variations in length, width and points of insertion were found. With regard to the rectus muscles, it was found that the superior rectus and lateral rectus are the longest muscles and that the width difference between the superior and inferior rectus is greater than that between the medial and lateral rectus and that the point of insertion of the rectus muscles has a variable morphology. The superior oblique muscle was smaller in caliber than the inferior oblique,...

Morphometric Study of Cervical Vertebrae C3-C7 in a Population from Northeastern Mexico
Provedor de dados: 77

Knowing the dimensions of the vertebral elements is very important for the development of instrumentation related to the cervical spine. Ethnic variations have been reported in these dimensions and, to date, there have been no morphometric studies of this area performed on the Mexican population. We conducted a morphometric study of 150 cervical vertebrae (C3-C7) obtained from a northeastern Mexican population to determine the dimensions of the bodies, pedicles, laminae, spinous processes, and superior and inferior articular processes. We did not find significant differences (p&lt;0.05) in measurements taken of the left and right sides. The dimensions of the vertebral bodies were larger at lower levels. The pedicles of the C3 vertebra were larger in all...
