The purpose of this report is to present our surgical technique using forged composites of unsintered hydroxyapatite particles/poly-L-lactide (F-u-HA/PLLA) pins for pediatric displaced fractures of the lateral condyle of the humerus, to retrospectively evaluate clinical outcomes, and to verify the advantages of this device by using postoperative radiographs.
Retrospective (level IV) case series.
Academic medical center.
From October 2004 to September 2006, 8 pediatric displaced closed fractures of the lateral condyle of the humerus (AO/OTA 13-B1) were treated.
Lateral condyle fractures were fixed using 2 threaded pins. All the patients were placed in a long arm cast for 4 weeks after surgery.
Radiographic and clinical outcomes and postoperative complications were evaluated.
The average follow-up period was 52.5 months. All fractures were successfully united. All shadows of pins were observed, and there were no radiolucent zones around the pins at the final radiographic follow-up. No patients experienced pain or cosmetic deformity at the most recent follow-up. Loss of reduction, malunion, deep infection, implant failure, osteolysis, skin ulcer, and foreign body reaction were not observed postoperatively. No patient required secondary operation.
Radioopacity of F-u-HA/PLLA devices is a major advantage of this device. No radiolucent zones were present around the pins, no osteolysis was observed on postoperative radiographs, and there were no postoperative complications. Reoperation for removal was unnecessary. Open reduction, internal fixation using F-u-HA/PLLA pins offers several advantages in treating pediatric displaced fractures of the lateral condyle of the humerus.

本报告旨在介绍我们使用未烧结羟基磷灰石颗粒/聚-L-乳酸（F-u-HA/PLLA）钉锻造复合材料治疗小儿肱骨外髁移位骨折的手术技术，回顾性评估临床结果，并通过术后 X 线片验证该器械的优势。
回顾性（IV 级）病例系列。
学术医疗中心。
2004 年 10 月至 2006 年 9 月，我们治疗了 8 例小儿肱骨外髁闭合性移位骨折（AO/OTA 13-B1）。
使用 2 枚螺纹钉固定外髁骨折。所有患者术后均用长臂石膏固定 4 周。
评估影像学和临床结果以及术后并发症。
平均随访时间为 52.5 个月。所有骨折均愈合良好。所有钉的阴影均可见，在最终 X 线随访时，钉周围无透亮区。末次随访时，无患者出现疼痛或美容畸形。术后无失复位、畸形愈合、深部感染、植入物失败、骨溶解、皮肤溃疡和异物反应。无患者需要二次手术。
F-u-HA/PLLA 器械的射线可透性是该器械的主要优势。钉周围无透亮区，术后 X 线未见骨溶解，无术后并发症。无需再次手术取出。使用 F-u-HA/PLLA 钉切开复位内固定治疗小儿肱骨外髁移位骨折具有许多优势。
治疗性 IV 级。请参阅作者说明以获取完整的证据水平描述。
