[Primary stability of cement free hip cup prostheses--morphometric comparative analysis of two cup types].

An uncemented implanted acetabular cup must ensure primary stability and postoperative osteointegration. For both conditions the immediate postoperative contact between bone and the structured surface of the cup is of decisive importance. Two different types of acetabular cups manufactured by ESKA (standard model and Kapuziner model) were implanted in the innominate bones of elderly deceased persons. After plastination, thin serial sections were obtained. On the basis of X-rays of these sections, contact between bone and the reticulate surface of the cups was quantified. The quality of the contact was analysed densitometrically.

[Cut type femur neck prosthesis--a functional morphologic analysis].

In contrast to other commonly employed models, the cut model femoral neck prosthesis is a cementless prosthesis of comparatively small dimensions. With the aim of investigating its functional integration in the femur, radiological, densitometric and photoelastic analyses were carried out. The biomechanical reaction of the bone tissue expected on the basis of the experimental result is tested in the clinical situation.
