肌骨超声在胫骨远端骨骺损伤诊断中的应用价值

Value of musculoskeletal ultrasound in diagnosing injury of distal tibial epiphysis

目的:探讨肌骨超声检查在儿童胫骨远端骨骺损伤诊断中的应用价值。方法:回顾性分析2016年1月至2019年11月广州市正骨医院小儿骨科收治的28例胫骨远端骨骺损伤患儿的临床资料,均在48 h内行X线片、肌骨超声检查和核磁共振(MRI)检查。以核磁共振检查作为诊断“金标准”,比较X线片、肌骨超声检查的检出阳性率。结果:28例患儿MRI检查均为阳性,X线片检查阳性率为71.4%,肌骨超声检查阳性率为89.3%,两种方法比较,差异无统计学意义(P=0.177)。结论:肌骨超声检查对胫骨远端骨骺损伤有明确诊断价值,具有无辐射、可重复操作、方便快捷等优势,能更好地得到家长的认同和接受,值得推广。

Objective:To investigate the value of musculoskeletal ultrasound in diagnosing injury of distal tibial epiphysis in children.Methods:A retrospective analysis was performed on the clinical data of 28 children with injury of distal tibial epiphysis admitted to the Department of Pediatric Orthopedics,Guangzhou Orthopedics Hospital,between January 2016 and November 2019.All patients underwent X⁃ray snapshot,musculoskeletal ultrasound and magnetic resonance imaging(MRI)within 48 hours of the injury.Using MRI as the gold standard for diagnosis,the positive rates were compared between findings of X⁃ray and musculoskeletal ultrasound.Results:The 28 children were 100%positive by MRI,71.4%by X⁃ray and 89.3%by musculoskeletal ultrasound.There was no statistically significant difference between the two modalities of diagnosis(P=0.177).Conclusion:Musculoskeletal ultrasound is definitely of diagnostic value for injury of the distal tibial epiphysis,showing advantages in terms of non⁃radiation,repeatability,convenience,quick and easy to use that are well recognized and accepted by parents and hence worthy of widespread use.
