自1990年6月至1991年5月共有4824個新兵於新兵訓練中心接受為期16週的基本體能訓練。經由病史，體檢、放射線學或核子醫學診斷發現518個新兵有677疲勞性骨折。發生率為百分之10.7。疲勞性骨折分佈如下：脛骨433個佔百分之63.8，蹠骨160個，佔百分之23.6，跟骨33個，佔百分4.8，股骨44個佔百分之6.5，腓骨8個，佔百分之1.2。百分之27的新兵有多發性疲勞骨折，百分之51.5的新兵其疲勞性骨折發生於訓練後第一個月。有二個股骨疲勞性骨折發生完全移位斷裂接受手術內固定治療。

Six hundreds and seventy-seven stress fractures in 518 military recruits were diagnosed by history, physical examination, radiographs or Tc-99m MDP whole body bone scan during a period of 16-week basic physical training program since June 100- to May 1991. Total population of training recruits during this period were 4824, and total incidence of stress fractures was 10.7%. The distribution of stress fractures were tibia, 63.8%, metatarsal, 23.6%, femur, 6.5%, calcaneus, 4.8% and fibula, 1.2%. Four hundreds and thirty-two tibial stress fractures occurred in 313 recruits, 57.4% located in middle third, 24.3% in lower third and 18.3% in upper third, thirty-eight percent of them involved both sides of tibia, and 42.5% of recruits happened stress fractures within first month after training. Thirty-nine recruits sustained 4 femoral stress fractures which 47.7% located in upper third, 29.6% in lower third and 22.7% in middle third, fifty-one percent of them were diagnosed within first month after training, two of which had displaced, lower third, femoral stress fractures and received open reduction and internal fixation with plate. Total 160 metatarsal stress fractures (146 in the second, 14 in the third metatarsal) in 134 recruits and 33 cal-caneal stress fractures in 24 recruits were found, fifty-eight per-cent of them occurred during first month. In conclusion, our total incidence of stress fractures was higher than United States Army (1.44%) but lower than Israeli Army (31%). Tibial stress fractures were the most common stress fractures in our series, 38% of them had bilateral involvements. Most of stress fractures (51.8) occur-red during the first month, with 28.7% in the third and fourth weeks.
