Classification and regression tree analysis for predicting morphological hand types based on radiography data

Int. j. morphol; 39 (6), 2021
SUMMARY: Analysis and systematization of the longitudinal dimensions of the phalanges of the index and ring fingers for the classification of morphological types of the hand using classification and regression trees (CART). X-rays of the hands of 50 men and 50 women (mean age 47.16 (10.1) years, range 23...

Atrofia monomiélica distal de extremidad superior. Caso clínico

Rev. méd. Chile; 149 (1), 2021
Monomelic amyotrophy, also known as Hirayama disease, is a rare lower motor neuron syndrome due to localized lower motor neuron loss in the spinal cord at the cervical level. Clinically, monomelic amyotrophy is defined by the insidious onset of unilateral atrophy and weakness involving the hand and forea...

Recommendations for improving photo quality in close range photogrammetry, exemplified in hand bones of chimpanzees and gorillas

Int. j. morphol; 38 (2), 2020
SUMMARY: Photogrammetry is becoming increasingly popular in morphological research and teaching due to its portability, ability to reliably render 3D models, and quality-to-price relationship relative to some popular surface scanners. Compared to surface scanners, however, the learning process in photogr...

Acrometástasis óseas, serie de casos y revisión de la literatura

Rev. chil. radiol; 25 (3), 2019
Resumen: Las acrometástasis se definen como metástasis óseas localizadas distales al codo y la rodilla. Su prevalencia es muy baja, aproximadamente el 0,1% de todas las metástasis óseas y se presentan en pacientes con enfermedad avanzada y son indicador de mal pronóstico. Hasta en el 10% de los cas...

A radiological investigation on the hand development in human fetuses throughout the fetal period and an evaluation performed in terms of its clinical importance hand development

Int. j. morphol; 34 (4), 2016
It was aimed in this study that the morphometric development of the hand in human fetuses throughout the fetal period be radiologically investigated and the clinical importance of this period be evaluated. A total of 50 fetuses with no external pathology or anomaly, and the ages of which varied between 2...
