超声检查在半月板损伤诊断中的应用价值

Application value of ultrasound examination in diagnosis of meniscus injury

目的探讨超声检查在半月板损伤诊断中的应用价值。方法 57例膝关节半月板损伤患者,采用关节镜手术治疗,术前采用超声检查,对超声检查的结果进行分析。结果关节镜下显示患者的半月板损伤有83个,其中内侧半月板损伤40个,外侧半月板损伤43个;超声检查与关节镜显示结果相符的半月板损伤有75个,其中内侧半月板损伤36个,外侧半月板损伤39个;超声检查诊断准确率为90.36%,内侧半月板准确率为90.00%,外侧半月板诊断准确率为90.70%。关节镜诊断半月板损伤类型分别为水平撕裂、纵行裂、桶柄状撕裂、横裂、外缘型和内缘型分别为23个、15个、17个、13个、6个和9个;超声诊断半月板损伤类型分别为水平撕裂、纵行裂、桶柄状撕裂、横裂、外缘型和内缘型分别为21个、14个、16个、12个、5个和7个,漏诊8个,漏诊率为9.64%。经治疗,患者症状均明显改善。结论超声检查诊断半月板损伤的诊断准确率较高,漏诊率较小,临床上可以将其作为半月板损伤诊断的辅助方法。

Objective To investigate application value by uhrasound examination in diagnosis of meniscus injury. Methods A total of 57 patients with knee joint meniscus injury received arthroscopic surgery for treatment. Analysis was made on outcomes of their preoperative ultrasound examination. Results Arthroscope showed 83 cases with meniscus injury, including 40 cases with medial meniscus injury and 43 cases with lateral meniscus injury. Ultrasound examination showed 75 corresponding cases with meniscus injury, including 36 cases with medial meniscus injury and 39 cases with lateral meniscus injury. Ultrasound examination had accuracy rate of diagnosis as 90.36%, accuracy rate for medial meniscus as 90.00% and accuracy rate for lateral meniscus as 90.70%. Diagnosis by arthroscope showed meniscus injury types as horizontal tear in 23 cases, longitudinal tear in 15 cases, bucket handle tear in 17 cases, transverse tear in 13 cases, outer type in 6 cases and inner edge type in 9 cases. Diagnosis by ultrasound showed meniscus injury types as horizontal tear in 21 cases, longitudinal tear in 14 cases, bucket handle tear in 16 cases, transverse tear in 12 cases, outer type in 5 cases and inner edge type in 7 cases, along with 8 misdiagnosed cases and misdiagnosis rate as 9.64%. After treatment, all patients had obviously improved symptoms. Conclusion Ultrasound examination shows high accuracy rate in diagnosis of meniscus injury, along with low misdiagnosis rate. Itcan be applied as a auxiliary method in clinical diagnosis of meniscus injury.
