The aim of our study was the evaluation of correspondence among collateral ligaments and other soft tissue injuries detected by MRI and by intraoperative findings in a consecutive series of patients treated for simple elbow dislocation.
After clinical and MRI examination, 16 out of 59 consecutive patients with moderate or severe instability after simple elbow dislocation were addressed to surgical treatment. There were 14 men and 2 women. The mean age was 39.6 years (range 16-69 years).
MRI showed full-thickness lesion of MCL in 9/16 patients (53.3%) and partial lesion in 6/16 patients (40%), and in 1 case, the MCL was considered intact. On the lateral side, MRI showed complete injury of LCL in 7/16 patients (46.6%) and partial injury in 7/16 patients (40%). No lesions of LCL were observed in 2 patients (13.4%). MCL was surgically explored in all the patients. We observed 10/16 full-thickness lesions (62.5%) and 6/16 partial lesions (37.5%). LCL was surgically explored in 11/16 patients. We observed 6/11 full-thickness lesions (54.6%) and 5/11 partial lesions (45.4%). In 3 cases, associated soft tissue injuries were detected. The rate of concordance between MRI and surgical findings was 87.5% (14/16 cases) on the medial side and 90.9% (10/11 cases) on the lateral side.
Our study demonstrated that MRI is a reliable and useful tool to investigate collateral ligaments and soft tissue injuries around the elbow and to plan the most adequate surgical treatment.
我们的研究旨在评估连续系列接受单纯肘关节脱位治疗的患者中，MRI 检测到的侧副韧带及其他软组织损伤与术中发现的对应关系。
对 59 例连续的单纯肘关节脱位后中重度不稳定患者进行临床和 MRI 检查后，对 16 例患者行手术治疗。其中男性 14 例，女性 2 例。平均年龄 39.6 岁（16-69 岁）。
MRI 显示 16 例患者中的 9 例（53.3%）存在前交叉韧带完全性损伤，6 例（40%）存在部分性损伤，1 例患者前交叉韧带被认为完整。外侧，MRI 显示 16 例患者中的 7 例（46.6%）存在完全性损伤，7 例（40%）存在部分性损伤。2 例患者（13.4%）未发现外侧副韧带损伤。所有患者均对前交叉韧带进行了手术探查，我们观察到 10 例（62.5%）完全性损伤和 6 例（37.5%）部分性损伤。对 16 例患者中的 11 例进行了外侧副韧带探查，我们观察到 6 例（54.6%）完全性损伤和 5 例（45.4%）部分性损伤。在 3 例患者中，还发现了其他软组织损伤。内侧侧副韧带和外侧副韧带的 MRI 与手术结果的符合率分别为 87.5%（14/16 例）和 90.9%（10/11 例）。
我们的研究表明，MRI 是一种可靠且有用的工具，可用于检查肘关节周围的侧副韧带和软组织损伤，并制定最合适的手术治疗方案。
