| 摘 要： | 本组52例胫骨疲劳骨折,均为男性新战士,年龄17～20岁(平均19.2％岁)。所有病例发生在3个月的新兵训练期间,部位以胫骨中上段前面或前内侧为主(84.6％)。通过对胫骨应力骨折发生的解剖基础和生物力学分析,提示该类骨折的发生与胫骨前内侧的“肌肉空白区”和其中上段凸向内的解剖结构有关,训练中胫骨受的应力不平衡,即后外侧压应力大而前内侧张应力大。张力是骨折的外在因素。分析了军训中跑、跳、蹬等动作导致胫骨疲劳骨折的机理,从而提出对这类损伤的预防措施。

| Abstract: | It is reported 52 cases of tibia fatigue fracture. All of the patients were recruits and 17 to 20 year old. The fracture took the place during training in three months, in their joining up army Most of injuries occured in supermedial and anterointeral tibia (84. 6%). The anatomic stuhure and biomechanics of this fracture are discussed. It is considered that tibia fatigue fracture is relative to the " muscle blank" region in anterointernal tibia and conex in supermedial tibia. They result in unbanlance stress on tibia during training, i, e. high compression on posterolateral region and high tension on anterointernal region. The unbanlance leads to tibia fatigue fracture. The mechanis, of this injury is discussed and the preventive methods are put forward. |
