FEMORAL-HEAD AUTOGRAFT IN SIMULTANEOUS PRIMARY AND REVISION TOTAL HIP-ARTHROPLASTY

Bilateral total hip arthroplasty during one anesthetic procedure can b e beneficial in properly selected patients. For patients who have a fa iled hip arthroplasty requiring revision and a contralateral arthritic hip requiring primary arthroplasty, bilateral surgery permits the res ected femoral head from the primary procedure to be used as a fresh au togenous bone-graft during the revision procedure. Four patients under went combined primary hip arthroplasty and contralateral revision hip arthroplasty during one anesthetic procedure. The femoral head obtaine d during the primary procedure was used as a structural acetabular bon e-graft in three patients, and bone slurry was used to fill cavitary a cetabular defects in one patient. A femoral neck autograft was used to reconstruct a calcar defect in one of the patients. After an average follow-up period of 27 months, all hips were functioning well with hea led bone-grafts and stable prosthetic components.
