[目的]探讨采用弹性髓内针留置引流法治疗儿童单纯性骨囊肿的临床疗效。[方法]2008~2013年采用弹性髓内针留置引流术治疗儿童单纯性骨囊肿39例,其中病变部位位于肱骨近端33例,股骨近端5例,胫骨1例。全部病例均获定期随访,随诊时间1.6~4年。治疗效果根据Capanne评价标准进行评价分析。[结果]囊腔完全愈合,囊腔内被骨组织填充,皮质增厚者21例,占53.8%;囊腔基本愈合,囊壁皮质骨增厚,但残存部分低密度区者15例,占38.5%;无反应者1例;复发2例。总体治愈率92.3%,仅1例存在皮下钉尾激惹反应,无内固定断裂及病理性骨折等严重并发症发生。[结论]弹性髓内针留置引流治疗儿童单纯性骨囊肿疗效明确、创伤小、并发症少,值得临床推广应用。
[Objective] To investigate the clinical efficacy of flexible intramedullary nailing and drainage in the treatment of simple bone cysts in children. [Methods] 39 cases of children with simple bone cyst were treated with elastic intramedullary nailing and drainage in 2008 ~ 2013. The lesions were located in 33 cases of proximal humerus, 5 cases of proximal femur and 1 case of tibia. All cases were regular follow-up, follow-up time of 1.6 to 4 years. Therapeutic effects were evaluated according to the Capanne evaluation criteria. [Results] The cyst completely healed and the cyst was filled with bone tissue. There were 21 cases of cortical thickening (53.8%). The cyst was basically healed and the cortical bone wall thickened. However, 15 cases remained in the low density area 38.5%; no response in 1 case; recurrence in 2 cases. The overall cure rate was 92.3%. Only 1 patient had subcutaneous nail-tip irritation reaction, and no serious complications such as internal fixation fracture and pathological fracture occurred. [Conclusion] Flexible intramedullary nailing drainage treatment of children with simple bone cysts clear effect, less trauma, fewer complications, it is worth promoting the clinical application.
