Injuries that develop secondary to minor traumas and cannot be detected via direct examination methods, but are detected via advanced imaging methods, such as magnetic resonance (MR) imaging, are called occult bone injuries or bone bruises. In such injuries, diagnostic arthroscopy usually does not reveal any pathology. MR imaging methods are quite beneficial for the diagnosis of such clinical conditions, which cause acute pain and restriction of motion. The present study aimed to assess occult bone injuries via MR imaging in patients who presented with minor knee trauma.
Twelve patients who presented with minor knee trauma were included in the study. Etiological factors in these patients included walking a long distance, falls, and minor trauma. All patients underwent physical examinations, direct radiological imaging, MR imaging, and diagnostic arthroscopy.
Direct radiographs of the patients showed no pathological fracture. Bone marrow changes detected on the MR images were classified according to Lynch's classification as Type I lesions in nine patients and Type II lesions in three patients.
We suggest that MR imaging methods should be the gold standard for the diagnosis of minor traumatic bruise injuries of the knee.
继发于轻微创伤且无法通过直接检查方法检测到，但可通过磁共振（MR）成像等先进成像方法检测到的损伤，称为隐匿性骨损伤或骨挫伤。在这类损伤中，诊断性关节镜检查通常不会发现任何病变。MR成像方法对于诊断这类导致急性疼痛和活动受限的临床病症非常有益。本研究旨在通过MR成像评估出现轻微膝关节创伤的患者的隐匿性骨损伤。
本研究纳入了12例出现轻微膝关节创伤的患者。这些患者的病因包括长途行走、跌倒和轻微创伤。所有患者均接受了体格检查、直接放射成像、MR成像和诊断性关节镜检查。
患者的直接X线片未显示病理性骨折。MR图像上检测到的骨髓改变根据林奇分类法，9例患者为I型病变，3例患者为II型病变。
我们建议MR成像方法应成为诊断膝关节轻微创伤性瘀伤损伤的金标准。
