Cementless custom-fit total hip implants on a patient with a rare form of dwarfism (Fuhrmann syndrome).

We present a single case study of a 47-year-old female patient with a rare form of primary dysostotic dwarfism. This syndrome was first described by F uhrmann in 1972. Seven years ago, this patient underwent bilateral cementle ss total hip arthroplasties for severe osteoarthritis about her hips. Custo m-made components were used. While achondroplastic patients present with wi de femoral medullary canals, it is clinically relevant that Fuhrmann Syndro me features narrow femoral medullary canals. This complicating anatomical f actor in Fuhrmann syndrome as well as the increased anteversion angles were overcome by the use of CAD stems. We conclude that the custom-made stems, althaugh in our case measuring half the size of the smallest commercially a vailable design, have proved to be durable and able to withstand physiologi cal loads at follow-up period of 72 months.
