超声诊断儿童三角肌挛缩症

Ultrasonographic diagnosis of deltoid contracture in children

目的探讨超声检查对三角肌挛缩症诊断的价值。方法回顾性分析37例双侧肩关节不对称患儿,其中手术证实8例三角肌挛缩症病例,比较其超声检查及手术结果。结果超声诊断儿童三角肌挛缩症的灵敏度为88.89%,特异度为100%。超声检查与手术测量挛缩带厚度差异无统计学意义。儿童三角肌挛缩症的超声影像特点为三角肌肌层内查见增强回声区(7例)或弱回声区(1例)。结论超声可作为三角肌挛缩症的有效诊断方法。

Objective To explore the value of ultrasonographic diagnosis of deltoid contracture （DC）. Methods A total of 37 children with bilateral asymmetric shoulder were reviewed retrospectively, and 8 cases with 9 shoulders were surgically confirmed DC. The results of the ultrasonography and surgery were compared. Results The sensitivity of ultrasonographic diagnosis of DC was 88.89% and specificity was 100%. No statistically significant difference of contracture thickness measurement was found between surgery and ultrasonography. Ultrasonographic findings of DC in children included hyperechoic areas （7 cases） or hypoechoic area （1 case）. Conclusion Ultrasounogrphy is an effective method for diagnosis of DC in children.
