Resumen (ES)
We analysed the results of forty eight hydroxyapatite
coated femoral component implanted in aseptic revision of the
hip. In 9 cases the defect was classified as type 1, in 27 of type
2 (12 of type 2-A, 6 of type 2-B and 9 of type 2-C) and in 12 of type
3. The follow-up was between 1 and 7 years with a mean of 3,9.
In 11 cases the x-rays were analysed by image capture with a
digital camera, being processed later with a computer and
equalization by histogram. No subsidence bigger than 2 mm
was observed in any patient, neither displacement varus-valgus.
In 32 there was cases an osteoporostic area in the area
ogreatter trochanter a year after the intervention; that was irregularity
they modified over the time. At the first postoperative
year an appropriate filling of the empty metaphyseal and
diaphyseal spaces was observed in all the patients, with an
excellent integration of the allografts. With digital images, the
recovery of the next bony structure as well as the absence of
suspicious lines of fibrous fixation was proven.
