A 10- to 13-year follow-up study of Harris-Galante type prosthesis in total hip arthroplasty

Long-term clinical results of Harris-Galante type prosthesis in total hip arthroplasty (THA) were evaluated in 27 hip joints of 25 patients (2 men and 23 women). Seventeen joints also received bone grafting on the acetabulum. Mean follow-up period was 11 years and 3 months. Clinical outcome was eval...

Description
Summary:Long-term clinical results of Harris-Galante type prosthesis in total hip arthroplasty (THA) were evaluated in 27 hip joints of 25 patients (2 men and 23 women). Seventeen joints also received bone grafting on the acetabulum. Mean follow-up period was 11 years and 3 months. Clinical outcome was evaluated using the hip score of the Japanese Orthopaedic Association, and the score was good and stable during the monitoring period. Implant stability, bone changes around the implant, and the occupancy rate of the stem in the medullary space were radiologically examined. As a result of stem, there was subsidence in 3 joints and loosening in 6. There were no cases of cup loosening. A pedestal was found in 12 joints, and 4 of them which were associated with a radiopaque line had stem loosening. Among the 21 joints without loosening, 8 had a pedestal but they were not associated with a radiopaque line. The 2 joints which developed osteolysis did not have loosening. Stem loosening was related to the stem occupancy rate in the distal part of the medullary cavity. Postoperative stem occupancy rate could be an important indicator for long-term clinical results. Stems for cementless THA should be designed to have a high occupancy rate in the distal part, and stems should also be carefully chosen to meet individual differences.
