目的 了解不同地区入伍战士骨密度情况,以及骨密度与训练中损伤的关系。方法 随机抽取来自山区和平原地区入伍新兵各40名,集中军训12周后,应用~(99m)Tc-MDP对其行全身骨显像,了解训练伤情况。采用单光子骨密度测量仪检测前臂骨骨密度。结果 山区组骨密度减低7例,占17.5％。平原组骨密度减低2例,占5％;核素显像骨损伤者,山区组为33人(81％),平原组12人(30％)(P<0.01);9例骨密度减低者均有训练伤,为100％。71例骨密度正常者中36例有训练伤,占49.9％。结论 来自山区的新兵中骨密度减低者多于平原地区入伍新兵。集中军训后,训练损伤山区组亦多于平原组。骨密度减低者更易发生训练伤。
Objective To understand the bone mineral density of soldiers in different regions and the relationship between bone mineral density and injury during training. Methods Forty recruits recruited from mountainous and plains regions randomly were recruited for 40 weeks. After intensive military training for 12 weeks, 99m Tc-MDP was used to perform whole-body bone imaging to understand the training injuries. Forearm bone mineral density was measured using a single photon bone density meter. Results In mountainous group, bone mineral density decreased in 7 cases (17.5%). In the plain group, bone mineral density decreased in 2 cases (5%); in the group of radionuclide bone injury, 33 (81%) in mountain group and 12 (30%) in plain group (P <0.01) Training injuries are 100%. Thirty-six of the 71 patients with normal BMD had training injuries, accounting for 49.9%. Conclusions Among the recruits from the mountains, the reduction of the BMD is more than that of the reclaimed recruits in the plain areas. After concentrating military training, there were also more training mountain groups in injury than in plain group. Bone mineral density is more prone to training injuries.
