Abstract

|
|
Stress fractures occur in normal bones as a result of accelerated physical activity. The incidence of stress fractures is high in the lower extremities, because of weight bearing Such fractures have been recognized in tibia, femur, metatarsal bones, lumber vertebra, sa4 roiliac joint, pubic bone, iliac crest, fibula and tarsal bones. As skeletal scintigraphy is very sensitive in diagnosis of stress fractures, it has been frequently used. It has been known that the scintigraphy of stress fractures depicts as arply marginated rounded or fusiform area of increased activity. A clinical study was done for the purpose of reevaluation of scintigraphic findings of stress fractures of the lower extremities. The results were as follows:
1. Three of the 14 patients showed multiple fractures.
2. Most of stress fractures occured in the tibia. Scintigraphic findings of those were ocaliz ed rounded or fusiform hot areas at the posterior and medial cortex of the tibia. In conclusion, this localized cortical hot area is a scintigraphic sign of stress fractures , which is relatively specific, not pathgnomic. The compression force may paly an important rile in the stress fractures which are developed at the posterior and medial aspect of the tibia
