Werners-R. Vincent-B. Bulstrode-C. Oxford University, England. J-Bone-Joint-Surg-[Br]. 1990 Nov. 72(6). P 1010-3. We have reviewed 368 osteotomies carried out for osteoarthritis of the hip at the Nuffield Orthopaedic Centre. Survivorship analysis showed that 10 years after osteotomy 47% had required no further surgery, and even after 20 years 23% had still not had a hip replacement. Hips with moderate arthritic change showed significantly better results than those with more severe degeneration. Osteotomies with varus angulation as well as medial displacement showed longer survival. Author-abstract.
