Introduction. The aim of the study was to analyze results
of hip arthroplasty with the use of the hydroxyapatite-coatedCorail
Material and methods.The study group consisted of 134 patients
(85 females and 49 males) who underwent 138 hip joint
arthroplastieswith the use of the Corail stem. The mean age of the
patients at surgery was 56.8 years (range from 22 to 75 years). The mean
follow-up period was 110.45 months.
Results. Before surgery all
patients were calssified as poor according to the Merle
d`AubigneiPostelaclassification modified by Charnley. The mean
post-operative improvement was 6.8 points. The outcomes were classified
as excellent in 98 patients, good in 26, satisfactory in 8 and poor in
6. Poor results were always related to loosening of implant components:
aseptic loosening of the acetabular cup in 4 cases, of the stem in 1
case and septic loosening of the whole endoprothesis in 1 case.
Periosteal calcification was noted in 13 cases (9.4%). According to the
Kaplan–Meier estimator, 8 years’ survival rate was 93.33% for the whole
implant and 97.77% for the stem.
Conclusions. Our follow-up data
from a mean of nearly 10 years indicate that the use of the Corail stem
substantially reduces hip pain and produces a lasting good clinical
outcome. With good surgical technique and in the absence of
complications, the risk of aseptic loosening is minimal.
