To describe the injury mechanisms and magnetic resonance imaging (MRI) findings in acute hamstring injuries of male soccer players using a systematic video analysis.
Descriptive case series study of consecutive acute hamstring injuries from September 2017 to January 2022.
Two specialized sports medicine hospitals.
Professional male soccer players aged between 18 and 40 years, referred for injury assessment within 7 days after an acute hamstring injury, with an available video footage of the injury and positive finding on MRI.
Hamstring injury mechanisms (specific scoring based on standardized models) in relation to hamstring muscle injury MRI findings.
Hamstring injury mechanism (playing situation, player/opponent behavior, movement, and biomechanical body positions) and MRI injury location.
Fourteen videos of acute hamstring injuries in 13 professional male soccer players were analyzed. Three different injury mechanisms were seen: mixed-type (both sprint-related and stretch-related, 43%), stretch-type (36%), and sprint-type (21%). Most common actions during injury moments were change of direction (29%), kicking (29%), and running (21%). Most injuries occurred at high or very high horizontal speed (71%) and affected isolated proximal biceps femoris (BF) (36%). Most frequent body positions at defined injury moments were neutral trunk (43%), hip flexion 45-90 degrees (57%), and knee flexion <45 degrees (93%). Magnetic resonance imaging findings showed that 79% were isolated single-tendon injuries.
According to a video analysis, most hamstring injuries in soccer occur during high-speed movements. Physicians should suspect proximal and isolated single-tendon-most often BF-hamstring injury, if represented injury mechanisms are seen during game play. In addition to sprinting and stretching, also mixed-type injury mechanisms occur.
使用系统视频分析描述男性足球运动员急性腘绳肌损伤的损伤机制和磁共振成像（MRI）表现。
2017 年 9 月至 2022 年 1 月连续急性腘绳肌损伤的描述性病例系列研究。
两家专门的运动医学医院。
年龄在 18 至 40 岁之间的专业男性足球运动员，在急性腘绳肌损伤后 7 天内接受损伤评估，有可用的损伤视频和 MRI 阳性发现。
与腘绳肌肌肉损伤 MRI 发现相关的腘绳肌损伤机制（基于标准化模型的特定评分）。
腘绳肌损伤机制（比赛情况、球员/对手行为、运动和生物力学体位）和 MRI 损伤位置。
分析了 13 名专业男性足球运动员的 14 个急性腘绳肌损伤视频。观察到三种不同的损伤机制：混合型（短跑相关和伸展相关，43%）、伸展型（36%）和短跑型（21%）。受伤时刻最常见的动作是变向（29%）、踢腿（29%）和跑步（21%）。大多数损伤发生在高或非常高的水平速度（71%），影响孤立的近端股二头肌（BF）（36%）。在定义的损伤时刻最常见的体位是中立位躯干（43%）、髋关节屈曲 45-90 度（57%）和膝关节屈曲<45 度（93%）。MRI 结果显示，79%为孤立的单肌腱损伤。
根据视频分析，足球运动员的大多数腘绳肌损伤发生在高速运动中。如果在比赛中出现代表的损伤机制，医生应怀疑近端和孤立的单肌腱-最常见的 BF-腘绳肌损伤。除了短跑和伸展运动外，还会发生混合型损伤机制。
