title: [Experience with using polymer-metal endoprosthesis in the treatment of medial fractures of the femur neck in elderly patients].
abstract: The author analyses his experience in using polymer metalic endoprostheses in 36 patients with medial fractures and false joints of the femoral neck in the elderly persons. The average age of the patients operated was 74 years. The head and the neck of the endoprosthesis were made of polymer: polyamide-12 and its limb was made of metal: titan BT-5. The immediate and the long-term results (6 months to 10 years) have been studied. The functional results of endoprosthetics were good in 27 cases (81.8%), satisfactory in 4 cases (12.2%) and bad in 2 cases (6%). Using polymer (polyamide-12) as a construction material for endoprostheses contributes to a softer transmission of the efforts and stresses from the articular cartilage to the subchondral and remote parts of the skeleton and improves the restoration of the biomechanical equilibrium between the endoprosthesis and the bone structure.
