Abstract
We studied the fixation of the Mecron cementless titanium screw cup ra diographically and histologically in 20 dwarf-goats after periods of 0 , 6, 26 and 52 weeks. In only 3 goats did histology show good bone-imp lant contact, whereas in the other 17 goats a fibrous membrane interfa ce was seen. This high failure rate is caused by the poor primary fixa tion and should be a warning against the use of this implant.
