Abstract

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 that 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.
