疲勞性骨折是一種過度使用肌肉力量以及在骨頭上造成的彎曲及衝擊力量已經超過骨頭所能承受而造成的傷害，導致骨頭發生代謝反應，繼發細微的骨膜反應或是穿過皮質骨的病兆。它通常發生在負重骨，如脛骨和蹠骨；是一種常見的運動傷害，而且大多數情況下是與運動相關的。在過去被報告過的案例裡，軍人近端腓骨疲勞骨折是一種少見的傷害，尤其是發生在雙側。我們要報告的是一位新兵被診斷出雙側近端腓骨疲勞性骨折，經過四星期治療後症狀獲得緩解。

Stress fracture is an injury caused by overuse of muscle forces with bending and impact forces acting on the bones. Overloading eventually occurred and will lead to a metabolic response in terms of minimal periosteal reaction and transcortical lesions. It occurs typically on the weight bearing bones, such as the tibia and metatarsal. It is a common sports injury and most cases are associated with athletics. Proximal fibular stress fracture, especially bilateral is an uncommon injury found among the military population. A military recruit with bilateral proximal fibular stress fracture was reported. After through assessment, the patient received four weeks of resting. The symptoms remitted gradually and subsided.
