摘要巨手症是一种罕见但特异性的营养失调性疾病。我们最近报道了交感神经功能亢进与巨手症有关。本文对4例脊髓型手畸形患者进行了手部骨骼的放射学检查。单纯X线摄片显示患侧手骨增大及强化影。X线片显示患侧掌指长度和宽度分别较健侧增加1.7%和8.8%，掌骨指数较健侧明显降低。在第二掌骨的X射线光密度测定（MD/MS法）中，骨密度比正常侧增加了10.6%。结果提示，脊髓灰质炎患者的骨肥大与巨肢症有关。营养失调可能对骨组织产生一定的影响。
Chiromegaly, localized hypertrophy of a hand, is known to be a rare but pathognomonic trophic disturbance in syringomyelia. We recently reported that the sympathetic hyperfunction was associated with chiromegaly. This time we carried out radiological studies of hand bones in 4 patients with syringomyelic chiromegaly. In simple roentogenography, enlargement and enhanced shadows of hand bones were recognized in the chiromegalic side. Radiographic measurements showed metacarpophalangeal length and width were increased by 1.7% and 8.8% respectively compared to the normal side, and metacarpal index was decreased significantly in the chiromegalic side. In X-ray photodensitometry (MD/MS method) of the second metacarpal bones, bone density was increased by 10.6% compared to the normal side. These results suggested that bone hypertrophy was associated with chiromegaly in patient with syringomyelia. Trophic disturbance may exert some influence on the bone tissue.
