Hybrid total hip replacement. A 5-10-year follow-up study of 106 patients.
Between 1987 and 1992, 135 hybrid total hip replacements (THR) were performed in 124 patients. 106 patients, mean age 63 (52-77) years with 113 hips were followed for a an average of 6 (5-10) years. Porous coated PCA cups with 2 pegs were used in 21 cases, the Universal porous coated PCA in 62 and the Kirschner integrity cup in 30. Anatomic PCA stems were used in 83 cases and Kirschner dimension PC stems in 30. The preoperative Harris Hip Score (HHS) was 47. At follow-up, patients were evaluated clinically and radiographically. The position of the acetabular and femoral components were measured and the condition of the cement mantle and the bonecement interface were determined. Postoperatively, the mean HHS was 89. 92% of the patients were symptom free. 3 THR were revised; 2 due to acetabular component loosening and 1 due to failure of the femoral component. The remaining cases were considered stable, although 3 cups were suspected of future loosening.
