Accessory bones, variants, and coalitions are not uncommon at the hand-wrist region. They are often overlooked because they are usually asymptomatic and found incidentally on imaging. However, they may sometimes present as a (painful) swelling or mimic a (sequel of a) fracture. Other symptoms may be attributed to impingement and exercise-related pain. Thorough knowledge of the anatomy, systematic imaging analysis, and the awareness of their existence are the clues to a correct identification. Plain radiography and magnetic resonance imaging (MRI) play a pivotal role in the correct diagnosis. In general, signal intensity on MRI is similar to the normal bony structures. However, concomitant bone marrow edema may indicate the presence of impingement. Therefore, MRI sequences with fat suppression should be included in case of symptomatic findings. This article provides a kaleidoscopic overview of some of the prevalent bony anomalies of the hand-wrist region and their potential pathogenic nature.
附属骨、变异和联合在手腕部并不罕见。它们常常被忽视，因为通常没有症状，是在影像学检查时偶然发现的。然而，它们有时可能表现为（疼痛性）肿胀或类似（骨折的）后遗症。其他症状可能归因于撞击和运动相关疼痛。对解剖结构的透彻了解、系统的影像学分析以及对它们存在的认识是正确识别的线索。X线平片和磁共振成像（MRI）在正确诊断中起着关键作用。一般来说，MRI上的信号强度与正常骨结构相似。然而，伴随的骨髓水肿可能提示存在撞击。因此，出现症状性表现时应包括脂肪抑制的MRI序列。本文对手腕部一些常见的骨异常及其潜在的致病性质进行了全景式概述。
