摘要
The results of revision of the acetabular component without cement, performed for aseptic loosening, were reported previously after a mean of forty-four months for 138 hips (132 patients). After ail additional mean duration of follow-up of almost five years, twelve patients (twelve hips) had died before they could be followed long enough for the Inter study and nine patients (eleven hips) had been lost to follow-up; thus, a total of 111 patients (115 hips) were available for follow-up at a mean of 100 months (range, seventy-eight to 135 months). Between the earlier and later times of follow-up, six: additional acetabuli had had a repeat revision: one, for recurrent dislocation; two, for infection; and three (which were stable), at the time of a revision of the femoral stem. No revision of the acetabular cup was performed because of aseptic loosening, and no cup was noted to have migrated. Radiographs were available for 105 patients (109 hips) at a mean of ninety-eight months (range, seventy-eight to 135 months). Five (5 per cent) of the 109 cups were surrounded by a complete radiolucent line and three (3 per cent), by a partial progressive radiolucent line. A radiolucent line adjacent to a screw was seen in association with two cups (2 per cent), and osteolysis was noted at the margin of four cups (4 per cent). Revision of the acetabular component with a porous-coated, nearly hemispherical fiber-metal component inserted without cement was associated with a high rate of excellent results at the seven to eleven-year follow-up examination.
