The metacarpal index (MCI) in 54 children with constitutional tall stature was mean (SD) 8.65 (0.8) and in 55 with Marfan's syndrome 9.15 (0.9). Indices in both groups showed arachnodactyly and differed from those found in normal individuals (< 7.9). Because the MCI is a poor discriminator patients with tall stature or clinical signs of arachnodactyly should be examined for additional signs of Marfan's syndrome or other hereditary disorders of connective tissue.
54名体质性身材高大儿童的掌骨指数（MCI）均值（标准差）为8.65（0.8），55名患有马凡综合征的儿童的掌骨指数为9.15（0.9）。两组的指数均显示出蜘蛛指，且与正常个体（<7.9）的指数不同。由于掌骨指数对身材高大或有蜘蛛指临床体征的患者鉴别能力较差，因此应对这些患者检查是否有马凡综合征或其他遗传性结缔组织疾病的其他体征。
