Resumen (ES)
The clinical and radiological results of 65 proximally
HA-coated femoral stems were assessed after a minimum
follow-up period of five years. The relationship between
remodelative changes and the stress patterns was clearly
disclosed by finite element modeling. Mean age was 56 years.
The most common etiology was osteoarthritis in 38 cases and
avascular necrosis in 15. Radiographic and clinical assessment
was done after Johnston and col's protocol and the
numeric rating of Merle D'Aubigne respectively. The mean
preoperative score was 8,5 points, becoming 17,4 points out
of 18 at the 5 years review. Occasional or absent pain was
fount in 98 % of the cases. There were radiolucency lines
surrounding the polished and sharp distal stem in 89 %, but
they were not present at the HA-coated zones. Reactive cortical
hypertrophy was present in 14 % and proximal small
osteolytics features in 11 %. According Engh's criteria, the
100 % of the stems were osteointegrated.
