目的：通过对应力性骨折患者和正常人群的骨密度测量、分析，为预防军事训练伤的发生提供理论依据。方法选择2010-2012年来我院就诊收住院的西南地区全训部队应力性骨折患者30人和同年龄阶段同性别正常体检官兵60人，用双能X线吸收法骨密度仪进行第2-4腰椎椎体和双侧股骨近端骨密度测量并进行比较分析。结果应力性骨折组中第2-4腰椎椎体骨密度均数为1.029±0.087 g/cm2，左右侧股骨近端骨密度分别均数为0.9252±0.151 g/cm2、0.9481±0.115 g/cm2；正常体检组第2-4腰椎椎体骨密度均数为1.145±0.112 g/cm2，左右侧股骨近端骨密度分别均数为1.113±0.105 g/cm2，1.130±0.081 g/cm2；两者经t检验有显著差异（P＜0.01）。结论疲劳型应力性骨折患者骨密度显著降低，在条件允许下可进行骨密度筛查，科学制定军事训练计划。

Objective To provide theoretical basis for the prevention of military training injury by measurement and analysis of bone mineral density ( BMD) in patients with stress fractures and normal population.Methods A total of 30 patients with stress fractures, who were from full exercise troops and were treated in our hospital from 2010 to 2012, were selected.Sixty normal soldiers with the same age and gender were also selected .BMD of the lumbar vertebrae ( L2-L4) and the bilateral proximal femurs was detected using dual energy X-ray absorptiometry .The results were compared and analyzed .Results In stress fracture group, the mean BMD of L2-L4 and the left and the right proximal femur was 1.029 ±0.087 g/cm2 , 0.9252 ±0.151 g/cm2 , and 0.9481 ±0.115 g/cm2 , respectively.And in normal group, the mean BMD was 1.145 ±0.112 g/cm2 , 1.113 ±0.105 g/cm2 , and 1.13 ±0.081 g/cm2 , respectively.The significant difference was observed after t-test ( P<0.01 ) .Conclusion BMD in patients with fatigue model stress fractures decreases significantly .If the condition allows , BMD screening should be conducted , in order to formulate military training plan scientifically .
