Análisis morfométrico de la apófisis coracoides mediante tomografía computarizada en Chile

Resumen

Objetivo Determinar la morfometría de la apófisis coracoides (Cor) mediante tomografía computarizada de hombro (TC hombro) en población chilena.

Método 162 TC hombro (90 género femenino y 72 masculino), edad promedio 55,9 ± 20,2 años, fueron analizadas mediante sistema computacional IMPAX.

Resultados Largo total Cor promedio de 41,0 ± 2,5 mm. Largo promedio del pilar superior de 20,5 ± 2 mm. Altura media pilar superior de 9,2 ± 1,2 mm. Ancho promedio pilar superior de 10,3 ± 1,5 mm. Altura media de la base de 13,4 ± 1,8 mm.

Conclusión En nuestra población el pilar superior es más ancho que alto y el largo total de Cor es aproximadamente el doble del largo del pilar superior. Todas las dimensiones de Cor son mayores en el género masculino versus femenino. Al comparar la morfometría de Cor, nuestra población es similar a otros grupos étnicos según lo descrito en la literatura.

Nivel de evidencia III.

Abstract

Purpose Define the morphometric measurements of the coracoid process (Cor) in Chilean population through the analysis of shoulder computed tomography (shoulder CT)

Method 162 shoulder TC (90 females and 72 males), average age 55.9 ± 20.2 years, were analyzed by IMPAX software.

Results The mean total Cor length was of 41.0 ± 2.5 mm. Average upper pillar length was 20.5 ± 2 mm. The mean upper pillar height was 9.2 ± 1.2 mm. The mean upper pillar width was 10.3 ± 1.5 mm. Average base height was 13.4 ± 1.8 mm.

Conclusions In our population, upper pillar is wider than high and the total Cor length is approximately twice than upper pillar length. All Cor dimensions are greater in males versus females. The Cor morphometric measurements in our population is similar to other ethnic groups as described in the literature.

Level of evidence III.
