踝关节扭伤是常见的军事训练伤,严重时可引起踝关节韧带断裂,目前临床上对下胫腓联合分离的影像学诊断尚无完善的客观指标,因此单纯性下胫腓联合分离常被漏诊。笔者自2005年起采用CT对新兵下胫腓联合进行扫描及测量,获得了新兵下胫腓联合最小间距参数,并经过11例战士下胫腓联合 Ankle sprain is a common military training injury, which can cause rupture of ankle ligaments in severe cases. At present, there is no perfect objective index for the imaging diagnosis of syndesmosis and syndesmosis. Therefore, simple tibiofibular syndesmosis is often missed . Since 2005, the author has used CT to scan and measure the tibiofibular syndesmosis of new recruits and obtained the minimum distance parameters of the tibiofibular syndesmosis recruits. After 11 cases of soldiers’ tibiofibular syndesmosis
