Stress Fractures in Our Hospital.

From 1982 to 1989, we have eight patients of stress fracture. Seven fractures occured in the tibia and one in ischium. From the routine anteroposterior and lateral X-ray, we measured the narrowest mediolateral and anteroposterior width of the tibia. We also measured the cortical thicknes. Patients of tibial stress fracture had shorter mediolateral width than the control group, but there are no significant difference in the anteroposterior width between the two groups. We cannot find significant difference in the cortical thickness, but there seemed to be tendency that thin cortex might be likely to be affected to the stress fracture. Six out of eight patients were military recruits. They were not athletic at all. About four weeks after the beginning of basic training, they feel pain. So we think that narrow mediolateral width of tibia and sudden increase of physical exercise may be risk factors of tibial stress fractures.
