INTRODUCTION
Avascular necrosis (AVN) of the bones of the wrist most commonly involves the lunate followed by the proximal pole of the scaphoid and the capitate. Trapezium avascular necrosis is extremely rare with only two cases reported in the literature, both of which were treated surgically. In this article, we report a unique case of trapezium avascular necrosis treated conservatively.
CASE PRESENTATION
A 38-year-old man complaining of a 4-month history of mild pain on the base of his right thumb. MRI scan was performed. The clinical presentation and the imaging findings indicated avascular osteonecrosis of the trapezium. The patient was treated with immobilization of the wrist joint for a period of six weeks. Three months later, the patient was free of symptoms and the MRI scan revealed a normal trapezium.
CONCLUSION
AVN of trapezium is extremely rare. Our case shows that immobilization of an early stage avascular necrosis of the trapezium might be a treatment option.
引言
腕骨的缺血性坏死（AVN）最常累及月骨，其次是舟骨近端和头状骨。大多角骨缺血性坏死极为罕见，文献中仅报道过两例，均接受了手术治疗。在本文中，我们报告了一例采用保守治疗的大多角骨缺血性坏死的独特病例。
病例介绍
一名38岁男性，主诉右手拇指基部有4个月的轻度疼痛病史。进行了MRI扫描。临床表现和影像学检查结果提示大多角骨缺血性骨坏死。该患者接受了为期六周的腕关节固定治疗。三个月后，患者症状消失，MRI扫描显示大多角骨正常。
结论
大多角骨AVN极为罕见。我们的病例表明，早期大多角骨缺血性坏死的固定治疗可能是一种治疗选择。
