Orthopaedic complications of renal transplantation.

One hundred and eighty-one patients who underwent renal transplantation between 1973 and 1979 have been reviewed. Thirty of these developed one or more orthopaedic complications. The commonest and most serious was avascular necrosis of bone and the treatment of 14 patients with this condition is described. Transplant recipients who developed this complication received twice the total dose of steroids in the six months after transplantation than a control group with no avascular necrosis. The management and pathology of patients with avascular necrosis is discussed.
