Resumen (ES)
This work analizes the first clinical and radiological results of a cementless hip
prosthesis with glass coating at metaphyseal level (CRM prosthesis). A total of 80 arthroplasties implanted
since may 1991 to 1994 were studied with a two year follow-up. The clinical assesment was
done by the modified Harris score, being satisfactory in 90% of the patients. The radiological study
demonstrated good fixation and orientation of the prosthetic compounds in 72 cases. The prosthetic
model studied provides a security mechanism both for primary and secondary fixation of the
femoral stem and acetabular cup.
