摘要
目的探讨三相骨显像对创伤后感染性骨折愈合不良的诊断价值。方法选择68例骨折内固定术后愈合不良患者,根据临床诊断分成感染组36例和非感染组32例,两组均行99mTc-MDP三相骨显像检查及外周血相关实验室检查,比较两组三相骨显像检查分析指标差异。结果感染组和非感染组各项检查结果定性资料比较,差异均有统计学意义(P<0.05);其中三相骨显像检查真阳性率和真阴性率分别为91.7%(33/36)和75.0%(24/32),准确率为60.3%;感染组和非感染三相骨检查A/N血流和A/N血池比较,差异有统计学意义(P<0.05)。结论三相骨显像对创伤后感染性骨折愈合不良的诊断准确率高且无创,具有较高的诊断价值,建议临床推广应用。
Aims To evaluate the clinical value of post-traumatic infection fracture by99mTc-MDP three-phase bone scintigraphy. Methods Sixty-eight patients with post-traumatic infection fracture were divided into infectious group（ 36 cases） and control group（ 32 cases） based on clinical diagnosis.99mTc-MDP three-phase bone scintigraphy and laboratory exams including complete blood count, erythrocyte sedimentation rate（ ESR） and C-reactive protein were performed. The diagnostic efficacy of all indexes were also evaluated. Results The diagnostic value of99mTc-MDP three-phase bone scintigraphy was superior to that of laboratory exams（ P〈 0. 05）, and there was significant difference between the two groups（ P〈0. 05）. Conclusions Three-phase bone scintigraphy is non-invasive and accurate with high predictive value in diagnosing post-traumatic infection fracture,and can be the recommended for clinical application.
