Fracture of theanterior processof the OS calcismay form partof a compres-sion-fracture ofthe body of thebone. As an iso-lated injury itmust be exceedingly rare,may also be involved. Fracture of the inframalleolar or trochlear process is alsoextremely rare. It is more apt to be produced by a directinjury splitting off the bony process, than by the actionof the calcaneo-fibular ligament, as was formerly tendons of the peronei muscles may be Fig. 158.—Fracture of the great toe. Wiese,male, thirty years old. Produced by a 100-poundweight falling on the foot. Fracture and abra-sion of the great toe, and fracture of the distalphalanx of the second toe.

The treatment of these injuries should be carried outaccording to general principles. In every case the footshould remain fixed in its normal position for a consider-able length of time. [Helbing ^ reports and illustrates a most interesting caseof tear-fracture of the os calcis. These are very rarefractures.
