Hamstring muscle injuries are the most prevalent injury sustained by elite-level football players.1 2 They account for as many as 24% and 12% of all injuries in European elite-level men’s and women’s football, respectively.1 2 The distal musculotendinous T junction (T-junction) of the biceps femoris muscle is formed by the confluence of the epimyseal surfaces of the anterolateral long head and posterolateral short head of the biceps femoris muscle (figure 1A). Entwisle et al 3 reported that biceps femoris injuries involving the T-junction have a particularly high rate of reinjury, however, this observation has recently been challenged.4 Figure 1 (A) Transverse ultrasound image illustrating the apex of the T-junction involving myotendinous connective tissue (yellow circle) and the deep myoaponeurotic connective tissue (red circle).

一名精英级足球运动员的“T 形连接”腿筋肌肉损伤


腿筋肌肉损伤是精英级足球运动员最常见的损伤。1 2 在欧洲精英级男子和女子足球中，腿筋肌肉损伤分别占所有损伤的 24% 和 12%。1 2 远端肌腱 T股二头肌的连接处（T 型连接处）由股二头肌前外侧长头和后外侧短头的上肌膜表面汇合而成（图 1A）。 Entwisle 等人 3 报道，涉及 T 形接头的股二头肌损伤的再损伤率特别高，然而，这一观察结果最近受到了挑战。4 图 1 (A) 横向超声图像显示了涉及肌腱的 T 形接头的顶点结缔组织（黄色圆圈）和深层肌腱膜结缔组织（红色圆圈）。 (B) 横向超声图像显示 T 形接头顶端的浅表局灶性缺损，涉及肌腱肌结缔组织（箭头），以及远端 T 形接头的深部局灶性缺损，涉及肌腱膜……
