Abstract：
OBJECTIVE: Simple bone cysts (SBCs) are the most common benign bone lesions in childhood. There are many different methods in the treatment of SBCs. There is no consensus on which method to use in the treatment. In this study, we compared the results of allogeneic bone graft or synthetic bone graft in addition to fl exible intramedullary nail (FIN) for SBC located in the humerus.
METHODS: This retrospective study comparing the data of 19 (group 1: 8 curettage, allograft and FIN; group 2: 11 curettage, synthetic graft and FIN) patients with a mean age of 11.4 (6 to 26; seven female, twelve male) who were surgically treated in our hospital for humeral SBC between April 2014 and January 2020. Patient data included age, sex, anatomical side, stage of the cyst, pathological fracture, previous treatments and complications.
RESULTS: The mean follow-up period was 33.7 months (12 to 61). The average last follow-up Musculoskeletal Tumor Society functional scores for groups 1 and 2 were 27.8 (20 to 30) and 28.6 (21 to 30) (P > 0.05). Complete or signifi cant partial radiographic healing rates were achieved in group 1 (75%) compared with group 2 (81.9%). The reoperation rates for groups 1 and 2 were 62.5% (5/8; three for nails removed, two for recurrence) and 36.3% (4/11; two for nails removed, two for recurrence). One patient in group 2 had a 15° varus deformity due to recurrence. No other complications were observed.
CONCLUSIONS: The combination of curettage-grafonage FIN is a common treatment method in recent years, as it provides early cyst healing and limb mobilization in SBCs located in the upper extremity. For defects after curettage of the bone cysts, allogeneic or synthetic grafts (granule b-tricalcium phospate) which have similar results in terms of healing can be used as an alternative to each other.

摘要：
目的：单纯性骨囊肿（SBC）是儿童时期最常见的良性骨病变。SBC的处理有许多不同的方法。对于在治疗中使用哪种方法没有共识。在这项研究中,我们比较了同种异体骨移植或合成骨移植的结果，除了固定髓内钉（FIN）外，SBC位于肱骨。
方法：这项回顾性研究比较了19例患者的数据（第1组：8刮治，同种异体移植和FIN；第2组：11刮宫，合成移植物和FIN）患者，平均年龄为11.4岁（6至26岁；7名女性，12名男性），2014年4月至2020年1月在我们医院接受肱骨SBC手术治疗。患者数据包括年龄，性别,解剖学方面，囊肿的阶段，病理性骨折,以前的治疗和并发症。
结果：平均随访时间为33.7个月（12至61个月）。第1组和第2组末次随访肌肉骨骼肿瘤学会功能评分平均分别为27.8分(20~30分)和28.6分(21~30分)(P>0.05)。与第2组（81.9％）相比，第1组（75％）实现了完全或明显的部分影像学治愈率。第1组和第2组的再手术率为62.5%(5/8；三个为去除指甲，两个用于复发）和36.3％（4/11；两个用于去除指甲，两个用于复发)。第2组中的一名患者由于复发而出现15°内翻畸形。未观察到其他并发症。
结论：刮宫结合FIN是近年来常用的治疗方法，因为它在位于上肢的SBC中提供早期囊肿愈合和肢体动员。对于骨囊肿刮除后的缺损，在愈合方面具有相似结果的同种异体或合成移植物（颗粒b-磷酸三钙）可以用作彼此的替代品。
