OBJECTIVE
Evaluating humeral head bone profile inside biceps reflection pulley area in order to identify possible anatomical variants and any causes predisposing to tendon's instability of the long head of the biceps.
MATERIALS AND METHODS
This retrospective study analyzed 326 patients, 183 males and 143 females (age 15-88 years; average 51.5 years), who underwent MRI examination between 2013 and 2019. Biceps pulley reflection area morphology of 192 right shoulders and 134 left shoulders was assessed analyzing 309 MRI and 17 MR arthrography (MRA) shoulder exams. We investigated age and gender and the frequency of morphological variants among the patient groups.
RESULTS
Four possible morphological variants were identified: 95 with convex shape; 127 with flat shape; 77 with spiculated shape; and 12 with mixed morphology. Fifteen humeral bone profiles were not classifiable.
CONCLUSIONS
MRI was effective in defining humeral head anatomic variants inside the biceps pulley reflection area. The most frequent variants were flat or convex types.
目的
评估肱二头肌反射滑车区域内的肱骨头部骨轮廓，以识别可能的解剖变异和任何导致长头肱二头肌肌腱不稳定的原因。
材料和方法
这项回顾性研究分析了 326 名患者，183 名男性和 143 名女性（年龄 15-88 岁；平均年龄 51.5 岁），他们在 2013 年至 2019 年间接受了 MRI 检查。通过分析 309 例 MRI 和 17 例 MRI 关节造影（MRA）肩部检查，评估了 192 个右侧肩部和 134 个左侧肩部的二头肌滑车反射区形态。我们调查了年龄、性别以及形态变异在患者群体中的发生频率。
结果
确定了四种可能的形态变异：95 例呈凸形；127 例呈平坦形；77 例呈刺状；12 例呈混合形态。15 例肱骨骨轮廓无法分类。
结论
MRI 可有效确定肱二头肌反射滑车区域内的肱骨头部解剖变异。最常见的变异类型为平坦或凸形。
