INTRODUCTION
A rare case of congenital bipartite lunate in a child is reported. Carpal variants are very uncommon as independent entities, with only three previous reports of this condition in the English literature.
CASE PRESENTATION
An 11-year-old Caucasian boy presented with pain in the left wrist after a fall. Radiographs in the emergency department demonstrated a lunate that was divided into palmar and dorsal parts, causing a misdiagnosis of fractured lunate. Magnetic resonance imaging was then used to differentiate between the two diagnoses.
CONCLUSION
Very few cases of bipartite lunate have been reported in the literature, and unless awareness is raised about congenital anomalies such as this variant, confusion may arise.
引言
报告了一例儿童先天性二分月骨罕见病例。腕骨变异作为独立病症非常少见，英文文献中此前仅有三篇关于此病症的报道。
病例介绍
一名11岁的白人男孩跌倒后出现左手腕疼痛。急诊科的X线片显示月骨分为掌侧和背侧两部分，导致误诊为月骨骨折。随后使用磁共振成像来区分这两种诊断。
结论
文献中报道的二分月骨病例极少，除非提高对诸如这种变异等先天性异常的认识，否则可能会产生混淆。
