An osteoid osteoma is a rare benign tumor of the carpal bones. It is extremely rarely found in the lunate bone in patients above 30 years of age. We present a case report of a 61-year-old man with an osteoid osteoma of the left wrist, which was masked by degenerative carpal bone disease and a comorbidity of an inflammatory bowel disease. The mainstay of imaging including plain radiographs, comp...

Distal radius fractures are common fractures of the upper extremity, estimated to account for one-sixth of all fractures seen and treated in emergency rooms.1-3 These fractures are seen in a bimodal age distribution and usually result from a low-energy trauma. Displaced fractures involving the articular surface of the distal radius have the worst prognosis because of the potential for incongrui...

The aim of this study was to investigate the feasibility of establishing dog models of lunatomalacia through liquid nitrogen freezing. Twelve adult crossbred dogs were divided into three groups. Unilateral lunates were peeled off the parenchyma and frozen to result in avascular necrosis. They were observed dynamically through X-ray, computed tomography (CT) and magnetic resonance imaging (MRI)....

Congenital fusion of the lunate [semilunar] bone with the triquetral [cuneiform] is an abnormality which has been considered to be rare, even in negroes, who have been regarded as specially subject (Shanks 1950). Smitham (1948) estimated its incidence in a series of West African natives to be one in seventeen (5’9 per cent), and if his experience is typical it is certainly much commoner in some...
