The Five-year Follow-up Study of Lord Total Hip Replacement

Abstract

During the period from August 1983 to January 1985, seventeen cementless total hip arthroplasties were performed and sixteen cases were completely followed. We discussed a relationship between the clinical results and the radiological evaluations.
Ten were satisfactory (62.5%) but three were poor in clinical results. The five-year postoperative roentgenograms of fifteen threaded rings showed a remarkable stability, but the tilting angles of the acetabular sockets in only eight cases were within normal limits. Seven of these eight cases were evaluated as satisfactory. Most affecting factor on the clinical results was an inadequate tilting angle of the socket. Radiolucent lines were evident in seven femora but the abnormal findings with the femoral components couldn't affect the five-year clinical results.
