Radiologic aspects of lunatomalacia.
A radiological classification of lunatomalacia, based upon the chronological radiologic manifestations in 93 patients is presented. Compression fractures were not seen as the initial event. Fifty-seven per cent of the patients had a short ulna (ulna minus variant). The presence of ulna minus variant was especially observed in the younger patients. In 16 patients suffering from a lunate fracture and in 20 patients with lunate or perilunate luxations, lunatomalacia did not develop. Immobilization as treatment of the disorder resulted in a progressive course in all patients, but one, an 8-year-old girl. The lesion of the lunate was arrested and tended to heal following radial osteotomy in all patients.
