55 cases of calcanear fractures (thalamus) have been treated with the Stulz procedure (early subtalar arthrodesis and calcanear reconstruction), associated with a repair of the great apophyse. All the cases are comparable and the results are considered as good or excellent in 93,8 p. 100 of them. The results are interpreted accordingly to subjective and objective tests. The result is depending of the type of the lesion, the patient's profession and the nature of the trauma. The result obtained at the time of fracture uniting will stay stable, will never deteriorate and sometimes improve. The early arthrodesis and reconstruction remains a good procedure for the comminutive fractures of the thalamus, which are considered as the most difficult to correct perfectly. For this reason, the simple reconstruction is often responsible of secondary subtalar arthrosis.
