RT Journal Article SR Electronic T1 Hip arthroplasty for ochronosis JF Saudi Medical Journal JO Saudi Med J FD Prince Sultan Military Medical City SP 1812 OP 1814 VO 26 IS 11 A1 Kerimoglu, Servet A1 Onder, Cetin A1 Aynaci, Osman A1 Malkoc, Cagatay H. YR 2005 UL http://smj.org.sa/content/26/11/1812.abstract AB Alkaptonuria is a metabolic disorder in which homogentisic acid oxidase is absent. Therefore, homogentisic acid accumulates in cartilage and connective tissues. We can diagnose ochronotic arthropathy, a manifestation of long standing alkaptonuria, through careful radiological, physical, and laboratory examination. In this report, we describe 4 cases of ochronotic arthropathy to which we applied cementless total hip prosthesis due to severe hip involvement.
