Since 1983 we have used cementless T. H. R. (JIAT) in severe osteoarthritis of the hip joint. We reviewed the results of 29 T. H. R. in 27 patients (average age, 63.7 years) who required autogenous grafting with bone from the femoral head for acetabular deficiency.
Roentgenographically bone grafts appeared to have united without evidence of resorption, to be communicated by bone trabeculae within an average period of 2.2 months, and to be remodeled within an average period of 6.3 months. 99mTc-MDP scintimetry was performed after operation, and bone graft uptake ratio was markedly decreased within an average period of 16 weeks.
We suggested that bone graft was reconstructed within 16 weeks.
