Resumen (ES)
We assessed the results after 810 total hip arthroplasties
with no cementation using an implant with
hidroxyapatite coating in two different hospitals. The index
procedure was indicated in primary hip osteoarthritis in
65.3% of the cases, and pain was the reason for operation
in 83.2% of the cases. Seven deep infections were recorded.
Thigh pain was present in twenty-seven patients
(3.3%), half of them during the immediate postoperative
period associated with a collapse of femoral component
(between 2 and 3 mm). Initial radiolucency areas were progressively
filled and disappeared. This phenomenon has
been interpreted as one of the beneficial features of
hidroxypatite (osteoconduction); total disappearance
occurs between the 8th and 10th weeks. These findings
allow us to state the benefit of implant surface coating
with hidroxiapatite, since it favors a better and earlier
implant to bone fixation.
