At the quadrangular joint (QAJ) of the carpus, a rare bony protuberance called carpal boss (CB) may occur. This bone abnormality may be due to osteophytes development or os styloideum. Symptomatic patients may complain pain, swelling, and restrictions in hand motion. These symptoms result from joint degenerative-inflammatory changes, development of ganglion cyst/bursitis, or tendons pathology. Correct diagnosis and appropriate management can be achieved through high-resolution ultrasonography (HR-US). The purpose of this review is to define the pathology spectrum around and within the QAJ in CB. The role of HR-US is highlighted and the standard technique for the QAJ assessment is described.
在腕关节的四边形关节（QAJ）处，可能会出现一种称为腕骨隆突（CB）的罕见骨突起。这种骨骼异常可能是由于骨赘的发展或茎突的形成。有症状的患者可能会抱怨疼痛、肿胀和手部运动受限。这些症状是由于关节退行性炎症变化、腱鞘囊肿/滑囊炎的发展或肌腱病变引起的。通过高分辨率超声（HR-US）可以明确诊断并进行适当的治疗。本综述的目的是定义 CB 周围和内部 QAJ 的病理学范围。强调了 HR-US 的作用，并描述了 QAJ 评估的标准技术。
