title: Humeral head osteonecrosis caused by electrical injury: a case report.
abstract: Various musculoskeletal abnormalities caused by electrical injury are described. Such abnormalities usually include fractures or dislocation of adjacent bones and joints. Osteonecrosis is a noteworthy, but less common, consequence of electric shock. The case is discussed of a 52-year-old woman who had received an electric shock (220-V alternating household current) to the right hand and developed osteonecrosis in the ipsilateral humeral head, most likely caused by bone "melting." An osteonecrotic lesion may therefore develop in a joint at a distance from the point of electrical contact, and this must always be kept in mind in diagnosis and treatment.
