Examples from the Web for malleoli
The talus is felt in front of the tibia, and the malleoli appear to be displaced backwards and to lie nearer the sole.
In all these injuries the body of the talus loses its normal relationship with the malleoli.
If there is extensive comminution of the os calcis or astragalus, the malleoli may be a little lower than normal.
The ankle joint is greatly swollen, the depression, normally present in front of and behind the malleoli, being obliterated.
This form is less often accompanied by a fracture of the malleoli than is the case in the backward dislocation.
- either of two rounded bony projections of the tibia and fibula on the sides of each ankle joint
C17: diminutive of Latin malleus hammer
