However, in young patients, it is still a controversial topic, not because of the results obtained, but because of the presumed need for revision of the prosthetics components in the future. Objectives: The present work performs a retrospective study of patients who underwent THA surgery in the past, in which the femoral head was transferred to the iliac for use in future revisions of total hip arthroplasty (autograft), and describes the proposed technique. Methods: The research reviewed 27 patients operated on using the femoral head autograft technique for the ipsilateral iliac in total hip arthroplasty, performed from 1996 to 2005;the study considered medical records, X-rays and CT scan images, and photographs taken at the time of surgery. Results: To date, only two revisions of total hip arthroplasty have been performed, in which the patients have benefited from the technique of autografting of the femoral head. No case evolved with infection or any other type of complication. All inserted grafts are consolidated and integrated with the iliac. Conclusion: The autograft technique is cheap, simple and reproducible, making available large amounts of bone for use in future revisions of total hip arthroplasty in young patients.展开更多
