Abstract
Ninety-six joints of 25 patients with hepatolenticular degeneration have been studied by means of scintigraphs with technetium (99mTc), a method which can disclose early synovial inflammation and postinflammatory articular degeneration. Signs of synovitis were found in 22 joints of 10 patients (40%) and degenerative changes were present in 15 joints of eight patients (32%). Eleven patients complained of joint pains; in four of them they were the presenting symptom. the radiological study showed osteoporosis in 22 patients (88%); flexion deformity was found in two cases, anomalous osteophytes in two, and signs of growth arrest, features of rheumatoid arthritis and aseptic necrosis in one case each. the pathogenesis of osteoarticular changes in Wilson's disease is discussed.
