武警新兵下肢应力骨折危险因素的病例对照研究

目的:探讨武警新兵基础训练期间下肢应力骨折的发生因素,为制定应力骨折的预防措施提供科学依据。方法:选择2009年3月～2012年2月于赤峰220医院确诊的48例下肢应力骨折的新兵,按照1:1的配比选取对照,对照组为同期参加训练而未发生应力骨折的新兵,配比条件是同性别、同年入伍、同期训练、参加相同训练内容。结果:新兵下肢应力性骨折发生率为10.4%(48/460)。应力骨折的危险因素为吸烟,OR值为2.009;保护因素为入伍前经常参加体育锻炼,OR值为0.240。结论:新兵下肢应力骨折的发生与多种因素有关。本研究显示入伍前经常参加体育锻炼,身体素质好的新兵应力骨折的发生率较低,入伍前吸烟的新兵应力骨折的发生率高,新兵基础训练期间应循序渐进,以降低应力性骨折的发生率。

新兵基础训练期间应力性骨折的发生率和分布特征

为了查明我军新兵基础训练期间应力性骨折的发生情况,作者于1992年1～3月,以~(99m)锝亚甲基二膦酸盐(~(99m)Tc-MDP)骨扫描为诊断依据,对某步兵师参训的1060名新兵进行了调查,发现应力性骨折的发生率为32.5％,正式开训后的第2和第7周为损伤高峰,训练强度较大的步兵分队的发生率(38.0％)高于炮兵分队(20.7％)及勤务分队(10.3％).各负重骨骼均可发生应力性骨折,但以胫骨最常见(占67％).作者指出应力性骨折是新兵对大强度军训适应过程中常见的损伤,不适当地增加训练强度可导致损伤人数的增多.应采用更科学的训练方法以减少应力性骨折的发生.     

新兵疲劳性骨折的诊治与预防

疲劳性骨折亦称应力性骨折,是军体训练中常见的损伤,尤其是新兵,发病率很高。以色列新兵团发病率高达31％,国内黄昌林等报告发病率为16.9％,应引起重视。总结我院自1994年以来收治战士疲劳性骨折126例中,当年度入伍新兵占92％,现报告如下。 1 临床资料 1.1 一例资料 本组共126例,男108例,女18例,其中当年度入伍新兵116倒,次年8例,第3年2例。年龄:18岁78例,19岁     

新兵基础训练期间应力性骨折危险因素的病例对照研究

应力性骨折是新兵基础训练中发生率较高、影响较大的一种训练伤，为了初步探讨其危险因素，为深入研究其病因提供线索，作进行了病例对照研究，经单因素分析及多因素Ｌｏｇｉｓｔｉｃ回归模型拟合分析发现，训练中曾有病休、难以跟上行军速度、较小的胫骨长度与腿长比值是ＳＦ的危险因素；作认为胫骨的相对长度（胫骨长／腿长）较绝对长度可能更能反映胫骨生物力学性能，带伤训练及疲劳状态下训练是有害的。

胫骨疲劳性骨折又名应力性骨折,在部队又称新兵应力骨折或行军骨折。我们自1989年11月至1991年11月共诊治24例。经X线检查证实22例。两例误诊骨肿瘤,但经手术证实为疲劳性骨折。报告如下: 1 临床资料 1.1一般资料:24例均为男性,年龄18至22岁,为新入伍战士。都有参加长跑,长途行军,登山、跳木马等训练后,患侧小腿局部隐痛,酸胀、麻木等症状,休息时减     

Incidence and distribution of stress fractures in recruits during basic training

Stress fracture(SF)in military recruits in China was investigated using~(99m)Tc-MDP bone scintigraphy in a randomized sample of 432 injured who wereclinically screened from 1060 recruits during basic training.The relationship between SFand training intensity was discussed.It was shown that the total incidence was 32.5%.There were two peaks during 9 training-weeks:one was in the 2nd week,and the otherin the 7th.Infantry soldiers had a more intensive training and,therefore a higher inci-dence than in artillery and service troops.Although SF was found in most ofweight-bearing bones,tibia was most commonly fractured(67%).The findings suggestthat SF is a major training-related injury in military recruits and improperly strengthenedtraining can increase the incidence.     

Stress fractures in military recruits: A prospective study for evaluation of incidence,patterns of injury and invalidments out of service

BackgroundStress fractures (SFs) occur because of repetitive submaximal stresses to the bone over a period of time. SFs cause an economic loss to the organization and to the individuals who get invalided out of army because of SFs. This study was conducted to determine the incidence, distribution, onset of SFs, and invalidment patterns due to SFs.MethodsThis prospective study was carried out among recruits undergoing training at training centres in a cantonment of Central India. The recruits enrolled were followed up through their training period for occurrence of SF. On occurrence of SF, the clinical features, site of bone involved, and the weeks of completed military training were noted. The SFs were graded into four grades based on clinicoradiological features and managed accordingly.ResultsA total of 8974 recruits were enrolled into the study, of which 208 recruits suffered SFs. The commonest bone involved was the tibia (86.5%), commonest site being the proximal one-third of the tibia shaft (46.2%). Average week of developing SF was the 15th week of training. Seven recruits were invalided out of army because of SFs, the commonest cause being femoral neck SFs.ConclusionPrevention is the best approach for SFs. It is suggested to increase the intensity of training gradually over the first 16 weeks and recruits are to be given a training pause at around the 12th week for healing of stressed bones just before the peak time of occurrence of SFs. Femoral neck SFs are the commonest SFs responsible for invalidment of recruits.     

Stress fractures—a prospective study amongst recruits

Background

Stress fracture (SF) is the single most common cause for the lost number of manpower days during training of recruits in the Armed Forces. This prospective study was undertaken with a view to develop baseline data on incidence of SF and to identify related variables.

Methods

A prospective study over a period of five years during 2004–2009 in which a total of 8,570 recruits were enrolled at the start of their training to find out the incidence and pattern of SFs.

Results

A total of 604 (7.04%, 95% CI 6.40–7.40%) out of a total of 8,570 recruits sustained SF during the study period. The majority of fractures occurred during basic training. The factors like urban residence, vegetarianism and those without prior history of physical activity were found to be associated with SF. Tibia was the commonest bone involved.

Conclusion

Prevention is undoubtedly the best approach in SF and other sports injuries. Priority should be given to individuals with good sports and physical activity background during recruitment. Intensity of training should be gradually increased during first three months (12 weeks) of training.Key Words: recruits, stress fracture

新兵集训期睡眠质量与自评训练量的关系

目的评价陆军新兵集训期间的睡眠质量及其与自评训练量的关系。方法采用整群抽样方法随机抽取某军区2011年度陆军参训的1389名新兵作为研究对象。用匹兹堡睡眠质量指数（Pittsburgh sleep quality index,PSQI）量表评价新兵集训第1、2、3个月的睡眠质量,通过新兵自评方式评价训练量。采用Kruskal-Wallis H检验、单因素及无序多分类logistic回归分析数据。结果新兵集训第1、2、3个月PSQI平均得分分别为（3.79±2.66）、（4.10±2.65）和（4.28±2.85）;3个月睡眠问题发生率依次为9.1%、10.7%、13.2%,呈现上升趋势（P〈0.05）。城市籍新兵在集训期间有2个月和3个月出现睡眠问题的风险低于农村籍新兵（OR=0.49、0.36）;自评训练量过大为新兵出现睡眠问题的危险因素,其中有1个月、2个月和3个月出现睡眠问题对应的OR值分别为2.24、2.57和2.08。结论部分陆军新兵集训期间存在一定程度的睡眠问题,农村籍新兵和自感训练量过大新兵应作为睡眠干预的重点。     

高频超声监测新兵军训应力性骨损伤的骨膜厚度变化

目的：应用便携式彩超高频探头观测新兵军训期间双侧胫骨前内侧骨膜厚度的动态变化,从而了解高频超声对应力性骨损伤的早期诊断价值。方法2012年12月~2013年4月,随机抽取300名右利手新兵作为研究对象,开训前均无下肢疼痛等不适症状。于开始训练前、训练1个月后及3个月后分别应用便携式彩超高频探头逐一测量双侧胫骨前内侧骨膜厚度。自胫骨结节至内踝之间分为上、中、下三等分,测量上等分和下等分,记录测量数据并进行对比。结果训练1个月后及3个月后双侧胫骨前内侧骨膜平均厚度均较开始训练前明显增厚（P ﹤0.05）;训练1个月后及3个月后双侧胫骨前内侧骨膜平均厚度差异不显著（P ﹥0.05）。以训练1个月后双侧胫骨前内侧骨膜增厚为著;以右侧胫骨前内侧骨膜上等分增厚为著。本组共有15例发生胫骨应力性损伤,其中右侧12例、左侧3例,上等分11例、下等分4例。应力性骨损伤的程度随着军训时间延长或强度加大而逐渐加重。结论便携式彩超高频探头对软组织病变具有良好的分辨能力,能及时准确地观测胫骨骨膜厚度的变化,可作为新兵军训阶段下肢应力性骨损伤的首选检查和诊断方法。右侧胫骨上等分为应力性骨损伤的高发部位。
