Abstract:
Objective To assess the clinical value of high frequency ultrasound diagnosis for little bone fracture of ankle. Methods Thirty-seven ankle wound patients with negative X-ray examination underwent high frequency ultrasound. The second X-ray examination was performed on patients with hinted little bone fracture of ankle, and then CT/MR examination was performed on patients whose second X-ray examination was negative. The consequence of the second X-ray examination was counted and the sonographic features were analyzed. Results ①Little fracture of fibula (lateral malleolus) was in 16, of tibia (medial malleolus) in 12, of talus in 2, of scaphoid bone in 4, of metatarsale in 2 and of calcaneus in one patients. ②The second X-ray examination was positive in 26 patients (26/37, 70.27%), indicating that the detection rate of the second X-ray is higher than that of the first X-ray. ③Sonographic features of little bone fracture of ankle included incomplete bone surface of bone was rough and soft tissue swelling and thickening. No malposition of bone fracture was found. Conclusion High frequency ultrasound is supplementary for X-ray examination, being able to possess important clinical priority in the diagnosis of little bone fracture.
