摘　　要：目的通过对应力骨折的临床表现、X线与CT征象进行分析,提高对应力骨折的认识。方法回顾性分析14例(15处)应力骨折资料,对发生原因、发病部位及X线与CT表现进行归纳、总结。结果14例中,疲劳性应力骨折9例,其中工人4例,运动员2例,军人1例,学生1例,旅行者1例;各种疾病伴发健骨衰竭性应力骨折5例。发生于胫腓骨4例,股骨颈2例,骨盆1例,第二跖骨4例,肋骨1例,足舟骨2例。不全性应力骨折9例,表现为局部皮质增厚,内可见横行短骨折线,周围骨质略有吸收,可有骨痂形成,CT扫描,在长骨可见典型的"双皮质征"。完全性应力骨折5例,表现为骨折线贯穿骨骼,断端分离,断面整齐、致密。结论应力骨折所涉人群在扩大,可发生部位在增加。中晚期X线与CT表现较具特征性。Objective To improve the knowledge of stress fracture by analyzing the relevant clinic performance,X-ray and CT-scan. Methods 14 cases（15 places of injury） of stress fracture were analyzed, the cause was probed into, the outbreak part, X-ray and CT-scan expression were summarized. Results In the 14 cases,there were 4 workers, 2 athletes, 1 soldier, 1 student, 1 traveler and 5 complicating diseases, while, 4 hurt in the tibia and fibular, 2 in the neck of femur, 1 in the pelvis,4 in the second metatarsal bone. 1 in ribs, and 2 in the navicular bone. According to the 9 incomplete stress fracture cases, partial cortex incrassation was obvious and transverse short fracture lines were found insides. The surrounding bone substance had been absorbed slightly and formed into bone scab. By CT scanning,typical ＂two layer cortex of the bones＂ could be found in the long bone. As symptoms of the other 5 complete stress fracture cases,fracture lines ran through the bone, the broken parts separated and the sections were tidy and fine. Conclusions The group of cases indicates that the crowd suffering stress fracture is enlarging,and the parts of injury are increasing. In the mid/later period,the X-ray/CT-scan represents characteristic performance.
