Symmetrical Bone Scan in a Patient With Acute Hypercalcemia

A previously healthy 49-year-old woman had symptoms of acute hypercalcemia that was not parathyroid-hormone mediated. Despite no clinical signs or symptoms of arthritis, a bone scan showed increased uptake in the juxtaarticular areas of the joints in the upper and lower extremities. The biopsy specimen of skeletal lesions noted on roentgenograms supported a diagnosis of multiple myeloma. Symmetrical lesions on bone scan in a patient with asymptomatic joints and acute hypercalcemia may be the first sign of an underlying hematologic malignant neoplasm.

Locking of the metacarpophalangeal joints in degenerative disease

Nine cases of locking of the metacarpo-phalangeal joint are described. The previously asymptomatic middle finger joint in an elderly person was most likely to be affected. Radiology of the joint has shown degenerative changes in all cases. In two patients, spontaneous unlocking of the joint occurred and in a further six operative release was undertaken. The important anatomical features of the condition are discussed in relation to the mechanism of locking and the surgical treatment.

A study of temporomandibular joint morphology and its relationship to the dentition

The evaluation of the temporomandibular joint is often attempted on the basis of morphology as viewed through x-ray projections. However, the normal morphologic range of asymptomatic temporomandibular joints has had little investigation. This study has determined to what extent development, maturity, advanced age, and occlusal relationships influence the articular parts of the temporal bone and the mandible and has established laminagraphic cephalometric norms for a given population (child, young adult, and aged). The findings are useful criteria for comparison with symptomatic joints.
