Morphometric Analysis of the Clavicles in Chinese Population

Abstract

The clavicle has a complex geometry that makes plate fixation technically difficult. <i>The current study aims to measure the anatomical parameters of Chinese clavicles as reference for plate design</i>. One hundred clavicles were analyzed. The clavicle bone model was reconstructed by using computed tomography images. The length, diameters, and curvatures of the clavicle were then measured. The female clavicle was shorter, more slender, and less curved in lateral part than the male clavicle. There was a positive relationship between height and clavicle parameters except lateral curve and depth. The measurements of Chinese clavicles were generally smaller than Caucasians. The clavicle curves were correlated with the bone length; thus consideration of the curve variations may be necessary as designing size distribution of clavicle plate.
