BACKGROUND AND PURPOSE
Radial head fractures are common, and may be associated with other injuries of clinical importance. We present the results of a standard additional MRI scan for patients with a radial head fracture.
PATIENTS AND METHODS
44 patients (mean age 47 years) with 46 radial head fractures underwent MRI. 17 elbows had a Mason type-I fracture, 23 a Mason type-II fracture, and 6 elbows had a Mason type-III fracture.
RESULTS
Associated injuries were found in 35 elbows: 28 elbows had a lateral collateral ligament lesion, 18 had capitellar injury, 1 had a coronoid fracture, and 1 elbow had medial collateral ligament injury.
INTERPRETATION
The incidence of associated injuries with radial head fractures found with MRI was high. The clinical relevance should be investigated.
背景与目的
桡骨头骨折较为常见，且可能与其他具有临床重要性的损伤相关。我们呈现了对桡骨头骨折患者行标准附加 MRI 扫描的结果。
患者与方法
44 例（平均年龄 47 岁）患者的 46 例桡骨头骨折接受了 MRI 检查。17 例肘部为 Mason Ⅰ型骨折，23 例为 Mason Ⅱ型骨折，6 例为 Mason Ⅲ型骨折。
结果
35 例肘部发现合并损伤：28 例存在外侧副韧带损伤，18 例存在肱骨小头损伤，1 例存在喙突骨折，1 例存在内侧副韧带损伤。
解释
MRI 检查发现桡骨头骨折合并损伤的发生率较高。应探讨其临床相关性。
