ABSTRACT
Until the present time the method of valuation of the bony integration of a cementless prostheses hip has been carried out with conventional X-rays, valuing indirect signs of bony integration initially, like it is the offspring’s non sinking, and long term radiological signs as it is the condensation bony periprosthesic it is for that reason that a protocol of study with TAC was elaborated in the period of April from the 2000 to February of the 2002, being carried out courts at metaphyseal level of a spaced thickness of 2.5 mm each 5 mm, in all the cases we use the same modular stem had of hydroxyapatite coated. So far 53 prostheses has been studied in 43 patients to which have been carried out TAC before with the cuts described immediate between the 1º and 7º day after surgery and to the 4 and 5 months and during the pursuit they were carried out radiological controls, at the 3, 6, 12 months and annual, being observed in the TAC studies ingrowth bony periprosthesic in all the cases being able to check a jump distance until of 4 mm that X-rays these changes are not observed.
