    Author: Ling RS.
    Journal: Chir Organi Mov; 1992; 77(4):373-81. PubMed ID: 1297571.
    Abstract:
    Results obtained with 433 cemented prostheses with original design, implanted at Exeter since 1969, are presented. Clinical and radiographic findings were evaluated on 88% of cases at 7,4-13, 4-16, 4 follow-ups. Average age at surgery was 66,7 years. Sixty-two (14,3%) prostheses have been revised. Stem loosening was evident in 13 (3%) cases, of which 11 were revised. Socket loosening was evident in 21 patients (4,9%), all revised. Due to sepsis 7 prosthetic were explanted (Girdlestone) were done. Stem sinking > 2 mm into the cement mantle was observed at 16,4 years follow-up in 15% of cases, with no relation to pain. None of the patients showed a complete radiolucent line around the stem. The biomechanical relevance of the tapered design of a smooth and collarless stem for the cemented implant is discussed.
