BACKGROUND
Aneurysmal bone cyst (ABC) is a benign, locally aggressive tumor that occurs in childhood and early adulthood. It usually affects the metaphysis of long bones but can also occur in the foot.
METHODS
This single-center study is a retrospective review of ten patients with primary ABCs of the foot which underwent an intralesional curettage or a polidocanol instillation.
RESULTS
After intralesional curettage a local recurrence was observed in 3/5 cases. The instillation of polidocanol showed a significant reduction of the initial cyst volume (p=0.0267). In the instillation subgroup a primary complete healing was achieved in three cases. Due to a persisting disease two cases were converted to intralesional curettage without local recurrence in the follow-up.
CONCLUSIONS
Percutaneous instillation of polidocanol is a minimally invasive treatment option for ABCs of the foot and especially for small bones. Nevertheless, several sequential instillations and a conversion to intralesional curettage can be necessary.
背景
骨动脉瘤样囊肿（ABC）是一种发生于儿童期和成年早期的良性、局部侵袭性肿瘤。它通常累及长骨的干骺端，但也可发生于足部。
方法
本单中心研究回顾性分析了10例足部原发性ABC患者，这些患者接受了病灶内刮除术或聚多卡醇注射治疗。
结果
病灶内刮除术后，5例中有3例出现局部复发。聚多卡醇注射显示初始囊肿体积显著减小（p = 0.0267）。在注射亚组中，3例实现了一期完全愈合。由于疾病持续存在，2例转为病灶内刮除术，随访中无局部复发。
结论
经皮注射聚多卡醇是治疗足部ABC尤其是小骨ABC的一种微创治疗选择。然而，可能需要多次连续注射并转为病灶内刮除术。
