ABSTRACT

Objective. To demonstrate the long-lasting of the Charnley total hip prosthesis in the original series of the autor. Material and methods. Out of 42 hips recorded at 20 to 25 years of duration, 10 needed a second surgery in that span, remaining 32 with their prosthesis able for the 25 to 30 year period. Results. Out from those 32 that started the period, 4 needed a revision surgery, 7 patients (8 hips) died and 8 were out of evaluation because of other diseases or severe senility. As a result, 12 patients with 15 otherwise well-preserved prosthetic hips, survived for the 25 to 30 years group. Waste of polyethylene cup was from 1 to 6 mm, with an average of 1 mm per every 9 years. Conclusion. Our results with this still useful prosthesis are similar to those from the Mayo Clinic and others. Even more, such details as current appropriate cementation techniques, avoiding trochanteric osteotomy and a better structure in polyethylene cups, should eventually improve the local conditions of the prosthesis and its durability.
