摘要:

背景:纳米级羟基磷灰石有利于改善骨植入体的力学性能。
目的:观察纳米羟基磷灰石人工骨修复塌陷型胫骨平台骨折的临床效果。 
方法:回顾性分析2010年3月至2012年9月,采用纳米羟基磷灰石人工骨治疗胫骨平台塌陷骨折14例合并骨缺损患者的临床资料,骨缺损范围为1.5 cm×1.0 cm-3.1 cm×4.5 cm,人工骨植入量为5-14 g。分别在治疗后1周、1个月和3个月进行临床和X射线片检查,观察治疗效果,HSS评分系统评估膝关节功能恢复情况。
结果与结论:随访12-27个月,除1例患者伤口处有少量渗出外,其余13例患者无术后发热、伤口红肿及过敏现象,伤口一期愈合,未发生切口感染等并发症。治疗后3个月观察,骨缺损区纳米羟基磷灰石与宿主骨直接愈合,相容性好,与原骨界面间无间隙,术后观察未见不良反应,治疗后1年HSS评分为(88.7±4.3)分。表明纳米羟基磷灰石人工骨具有良好的生物相容性,生物力学良好,对于塌陷型胫骨平台骨折是一种较理想的骨缺损修复材料。

Abstract:

BACKGROUND: Nano-hydroxyapatite helps to improve the mechanical properties of bone implants.
OBJECTIVE: To study the clinical effect of nano-hydroxyapatite artificial bone on collapsed fracture of the tibial plateau. 
METHODS: Fourteen cases of collapsed fracture of the tibial plateau combined with bone defects from March 2010 to September 2012 were analyzed retrospectively. The bone defect range was from 1.5 cm×1.0 cm to    3.1 cm×4.5 cm. All patients were treated with nano-hydroxyapatite artificial bone at an implant amount of 5-14 g. Clinical and X-ray observations were applied at 1 week, 1 month and 3 months postoperatively. Hospital for Special Surgery scores were employed for recovery of knee function.
RESULTS AND CONCLUSION: The patients were followed up for 12-27 months. Except for one case of a small amount of wound exudates, no general side effects occurred in 13 cases. X-ray photo showed an integrity interface between nano-hydroxyapatite artificial bone and host bone at 3 months after treatment. Primary healing was obtained in all cases without any complications. Hospital for Special Surgery score was increased to (88.7±4.3) points at 1 year later. These findings indicate that the nano-hydroxyapatite artificial bone has a good biocompatibility and biomechanics, and it may be an ideal artificial bone for repairing collapsed fractures of the tibial plateau.
