ABSTRACT
Patterns and variant morphometries of calcaneal articular facets on talus are concerned before performing of joint ankle surgery, including used as a sex determination. Types of talar facets have been documented in many populations except in Thai race. Therefore, this study attempted to classify the types of talus facets and to measure the facet lengths on dried tali of Thais. The 372 dried tali (204 males, 168 females) from Khon Kaen University Bone Collection were observed for variant types and measured for their facet lengths. The facets were classified into 6 types type I, tree facet are separated (1.88 %); type II (A), the anterior and middle facets are partially connected with predominant ridge (34.68 %); type II (B), the anterior and middle facets are partially connected with slight ridge (32.53 %); type III, the anterior and middle facets are fully fused to form a single facet (2.96 %); type IV, the anterior and middle facets are partially separated by a ridge and partly by a groove (27.42 %); type V, all facets are continuous fused to form a single facet (0.54 %). In addition, the morphometric lengths of AP (anterior to posterior process) and ML1&2 (medial to lateral process) in male are significantly greater than those of female. The AP, ML, and ML2 of male are 56.71±0.16, 41.63±0.18, and 37.85±0.36 mm, while of female are 51.21±0.12, 37.74±0.16, and 33.85±0.28 mm, respectively. This incidence can be used as ankle surgery consideration and an anthropological marker for sex determination of unidentified talus.
RESUMEN
Los patrones y las variantes morfométricas de las facetas articulares calcáneas en el talus deben considerarse antes de la realización de la cirugía del tobillo a nivel articular, incluido su uso para la determinación del sexo. Se han documentado los tipos de facetas en el talus en muchas poblaciones, excepto en la raza tailandesa. Por lo tanto, este estudio clasificó los tipos de facetas del talus y se midieron las longitudes de las facetas del talus, en muestras secas de indiviuos tailandeses. Se analizaron 372 talus secos (204 de hombres, 168 de mujeres) de la colección de huesos de la Universidad Khon Kaen, se observaron distintos tipos de variantes y se midieron las longitudes de las facetas. Las facetas se clasificaron en 6 tipos tipo I, faceta de árbol separadas (1,88 %); tipo II (A), facetas anterior y media parcialmente conectadas con la cresta predominante (34,68 %); tipo II (B), facetas anterior y media están parcialmente conectadas con una ligera cresta (32,53 %); tipo III, facetas anterior y media están completamente fusionadas para formar una sola faceta (2,96 %); tipo IV, facetas anterior y media están parcialmente separadas por una cresta y en parte por una ranura (27,42 %); tipo V, todas las facetas se fusionan continuamente para formar una sola faceta (0,54 %). Además, las longitudes morfométricas del proceso anterior o posterior (AP) y del proceso medial a lateral (ML1 y ML2) en el varón son significativamente mayores que las de la mujer. El AP, ML1 y ML2 de los hombres son 56,71 ± 0,16, 41,63 ± 0,18 y 37,85 ± 0,36 mm, mientras que las mujeres son 51,21 ± 0,12, 37,74 ± 0,16 y 33,85 ± 0,28 mm, respectivamente. Esta incidencia se puede utilizar como una consideración en la cirugía de tobillo y un marcador antropológico para determinar el sexo del talus no identificado.
