We describe a new imaging sign, the "superior cleft sign", identified at both symphysography and MRI, which should be used as a marker of rectus abdominis/adductor longus attachment tearing.
A study population of 25 patients presenting with clinically suspected sportsman's hernia, who had undergone both symphysography and MRI of the groin were included for study. In each case, images were reviewed to determine the presence of a superior cleft, secondary cleft, and or both abnormalities.
Images of all patients complaining of groin crease discomfort similar to sportsman's hernia revealed the presence of a superior cleft at the rectus abdominis/adductor longus attachment. This "superior cleft sign" correlated with the side of symptoms in each case, and, in contrast to the previously described secondary cleft along the inferior margin of the inferior pubic ramus, occurred parallel to the inferior margin of the superior pubic ramus.
The presence of the "superior cleft sign" should be sought in addition to the previously described secondary cleft sign in sportspeople presenting with exercise-related groin pain or pubalgia. It should specifically be sought in patients referred with suspected sportsman's hernia.
我们描述了一种新的影像学征象，即“上裂征”，在耻骨联合影和 MRI 上均可识别，可作为腹直肌/内收长肌附着撕裂的标志物。
本研究纳入了 25 例临床疑似运动疝患者，这些患者均进行了耻骨联合影和腹股沟 MRI 检查。在每种情况下，都对图像进行了审查，以确定是否存在上裂、次级裂或两者均存在异常。
所有抱怨腹股沟皱褶不适类似于运动疝的患者的图像均显示腹直肌/内收长肌附着处存在上裂。这种“上裂征”与每个病例的症状侧相关，与之前描述的沿耻骨下支下缘的次级裂不同，它与耻骨上支下缘平行。
在运动相关腹股沟疼痛或耻骨炎患者中，除了之前描述的次级裂征外，还应寻找“上裂征”。在疑似运动疝患者中，应特别注意寻找该征象。
