Clinical value of magnetic resonance imaging (MR) in traumatic bone contusion of knee joint
膝关节外伤性骨挫伤应用磁共振(MR)检查的临床价值研究

摘要

目的 分析磁共振（MR）检查应用在漆关节外伤性骨挫伤中的临床价值。方法 对笔者任职医院在2021年11月至2022年7月期间骨外科收治的60例膝关节外伤性骨挫伤患者进行回顾性分析。该组患者均接受CT检查和MR检查，并以病理结果为标准，比较不同方法检查结果与病理结果符合率，分析不同检查方法对膝关节外伤引起的不同骨挫伤的诊断效果。结果 该组60例患者经病理检查最终确认损伤类型包括韧带损伤21例、半月板损伤18例、关节腔积液13例、膝关节软组织血肿8例。CT检查结果显示上述损伤类型依次为17例、13例、11例、6例，诊断符合符合率为78.33%; MR检查结果显示上述损伤类型依次为21例、15例、12例、8例，诊断符合率为93.33%，显著高于CT检查结果（P<0.05）。结论 MR检查可提高膝关节外伤性骨挫伤的诊断率，便于临床及时采取正确的救治方案，临床应用价值确切，值得推广借鉴。

Abstract

Objective To analyze the clinical value of magnetic resonance (MR) in traumatic bone contusion of lacquered joint.
Methods A retrospective analysis was made on 60 patients with traumatic bone contusion of knee joint who were treated in the Department of Orthopaedics in our hospital from November 2021 to July 2022. All the patients in this group received CT and MR examination, and compared the coincidence rate between the results of different methods and pathological results based on pathological results, and analyzed the diagnostic effects of different methods on different bone contusions caused by knee joint trauma.
Results The pathological examination of 60 patients in this group finally confirmed that the injury types included ligament injury in 21 cases, meniscus injury in 18 cases, joint cavity effusion in 13 cases, and soft tissue hematoma in knee joint in 8 cases. CT results showed that the above types of injuries were 17 cases, 13 cases, 11 cases and 6 cases in turn, and the diagnostic coincidence rate was 78.33%. MR examination showed that the above types of injuries were 21 cases, 15 cases, 12 cases and 8 cases in turn, and the diagnostic coincidence rate was 93.33%, which was significantly higher than that of CT examination (P<0.05).
Conclusion   MR examination can improve the diagnosis rate of traumatic bone contusion of knee joint, and it is convenient for clinic to adopt correct treatment plan in time. It has definite clinical application value and is worth popularizing.
