[Mechanism of articular fracture of the calcaneus in experimental, pathological, roentgenographic and computerized tomography examination].

The experiments on amputated extremities, pathological examination as well as plain and computerized radiology confirmed existence of two basic types of calcaneal articular fractures: tongue type and crush type. An accurate anatomy of the experimentally fractured os calcis could be restored only after Westhues. An articular surface in crush fracture could be restored only in open arthrotomy. Computerized tomography revealed the type of the fracture and the degree of calcaneal destruction very precisely but was of no practical value in the treatment of the os calcis fractures.
