伞兵部队在平时训练中,如遇地形复杂,气象条件差或技术掌握不熟练时,着陆容易发生扭伤或骨折。尤以踝关节受伤为最多,其次是胫腓骨下三分之一处骨折及颈腰椎压缩性骨折。因为伞兵负荷量大,踝关节结构复杂,肌腱多,肌肉少,保护能力差,又承受着全身的重量,所以容易扭伤骨折。因此改进护踝以保 Paratrooper forces in peacetime training, in case of complex terrain, poor weather conditions or technical unskilled, landing prone to sprains or fractures. Especially the ankle injuries were the most, followed by tibiofibular fractures and cervical lumbar vertebral compression fractures. Because the paratrooper load, ankle complex structure, tendons and more, less muscle, poor protection, but also to bear the weight of the whole body, so easy to sprain fractures. Therefore, to improve ankle protection
