背景:新战士在新兵训练期间出现腰椎椎弓峡部断裂发病率较高并影响了正常训练。目的:分析部队新兵中腰椎椎弓峡部断裂的发病率与训练及其腰部原有病变的关系。设计:随机抽样调查。单位:解放军第九十七医院骨科。对象:某部2003年入伍的新兵100名,男性,平均年龄18.7岁。方法:对100名新兵全程追踪随访,于训练前及100d强化训练后分别摄腰部X射线正、侧位和双斜位片进行对照观察。主要观察指标:椎弓峡部断裂病例发病率,原有断裂者有无滑脱等加重现象。结果:调查对象100名均进入结果分析。①新兵训练前、后椎弓峡部断裂发病率:训练开始前的入伍新兵,L5椎弓峡部断裂5例,发病率为5%。100d训练结束时,腰椎椎弓峡部断裂8例,发病率增加至8%。②新兵训练前、后X射线检查结果:100名新战士X射线片训练开始前,左侧L5椎弓峡部变细2例,右侧L5椎弓峡部变细1例;双侧L5椎弓峡部断裂5例,其中1例呈I度滑脱。100d训练结束时,原双侧L5椎弓峡部断裂5例中I度以内滑脱3例,另3例原腰椎椎弓变细者均发生断裂。结论:腰椎椎弓峡部断裂发病率与训练强度有关。建议加强入伍新兵脊柱体检,常规加拍腰椎正、侧位和双斜位X射线片检查项目。
Background: New fighters have a high incidence of lumbar spine isthmus rupture during boot camp training and affect normal training. OBJECTIVE: To analyze the relationship between the incidence of lumbar spondylolysis and training and its original lumbar pathology in recruits. Design: Random sample survey. Unit: the 97th People’s Liberation Army orthopedic hospital. Object: 100 recruits recruited in 2003, male, average age 18.7 years old. Methods: A total of 100 recruits were followed up for follow-up. Before training and 100 days after intensive training, the radiographs of the lumbar X-ray, lateral view and double oblique disc were compared respectively. MAIN OUTCOME MEASURES: The incidence of fracture cases of the isthmic spondylosis, the presence or absence of slippage of the original rupture and other aggravating phenomena. Results: All 100 subjects were involved in the result analysis. ① recruits training before and after the incidence of vertebral arch isthmus: recruits recruits before the start of training, L5 pedicle isthmus fracture in 5 cases, the incidence was 5%. At the end of 100d training, 8 cases of lumbar spondylolysis ruptured, the incidence increased to 8%. (2) X-ray examination results of recruits before and after training: before the start of training of 100 new warrior X-ray films, left isthmus isthmus was thinned in 2 cases and left isthmus wasis in 1 case; bilateral L5 vertebral isthmus Five cases were ruptured, of which one case had grade I spondylolisthesis. At the end of 100d training, the spondylolisthesis of the original bilateral L5 spondylolysis in 5 cases within 1 degree of spondylolisthesis in 3 cases, and the other 3 cases of lumbar spondylolisthesis were ruptured. Conclusion: The incidence of lumbar spondylolysis is related to training intensity. It is suggested to strengthen the recruit recruits spine examination, routine plus lumbar spine, lateral and double oblique X-ray film inspection items.
