title: The treatment of femoral neck fractures with an isoelastic endoprosthesis implanted without bone cement.
abstract: We report about our first experiences inserting an "isoelastic" femoral endoprosthesis in cases of a fractured femoral neck. 28 patients have been observed for a period of more than 1 year after surgery. We did not find loosening or incompatibility of the polyacetal-resin material. We believe the implantation of this prosthesis type without cement fixation is especially advantageous. The histologic result of a patient who died 6 weeks after surgery did not reveal any tissue incompatibility. We observed an excellent fixation of the prosthesis by bone growth into the surface indentations of the stem.
