Radiographic Skeletal Survey Research Articles

MULTIPLE OSTEOSARCOMATA

Although an osteosarcoma appears to be a solitary lesion clinically, as in this instance, only routine radiographic skeletal survey in such cases will detect multiple osseous involvement. Ross (1964) reported that in ninety-eight cases of osteosarcoma arising in apparently normal bone, fifteen showed metastases to other bones, a much higher incidence than previously recorded. It is also possible that multicentric osteosarcomata, although undoubtedly rare, may be discovered more often if a radiological survey is done. In many large series of osteosarcomata no mention of a skeletal survey has been made, and, while this is routine in some centres, it is not yet general practice.

H˦moglobin SC disease

A radiographic skeletal survey was carried out on 20 cases of h˦moglobin SC disease. Slight but significant changes in bone texture of the skull and long bones were noted in about one-third of the patients. These were not related to age or degree of an˦mia. In h˦moglobin SC disease bone infection is very frequent. Avascular joint changes were noted in one-third of the cases, the hips and shoulders being most frequently involved. The avascular process is multifocal, discrete, and subchondral.
