Abstract

Unilateral congenital ulna deficiency of wrist and forearm is rare. It is associated with cartilaginous ulnar anlage, absence of ulnar digits, carpus, partially or completely absent ulna, radiohumeral synostosis, syndactyly, and thumb abnormalities. Various classifications have described this presentation. We report a new variant of type I congenital ulnar deficiency in wrist and forearm with a normal thumb, first webspace, hand, wrist, and elbow in an 18-year-old girl.

摘要

单侧先天性腕部和前臂尺骨缺如较为罕见。它与软骨性尺骨原基、尺侧手指缺如、腕骨、部分或完全缺如的尺骨、桡肱关节融合、并指以及拇指畸形有关。已有多种分类描述了这种表现。我们报告了一名18岁女孩的I型先天性腕部和前臂尺骨缺如的新变异型，其拇指、第一掌骨间隙、手部、腕部和肘部均正常。
