POSITRON EMISSION TOMOGRAPHY PET allows the visualisation of the metabolic activity of disease. Helps in diagnosis of malignant tumours and their recurrence. Also helps in the staging of tumours and the monitoring of their response to therapy, and in the diagnosis of osteomyelitis. The positron-emitting tracers may be used to define: Amino-acid uptake (11C-methionine; […]
CONGENITAL SUBLUXATION OF THE WRIST (MADELUNG’S DEFORMITY) Pathogenesis (Brailsford): Stunted development of inner third of the growth cartilage at the lower end of the radius, due to still unknown cause. Growth of the outer two-thirds continues and, as a result, the radial shaft is bowed backwards, the interosseous space is increased, there is overgrowth of […]
Fibrous Dysplasia originally described by Lichtenstein in 1938 and by Lichtenstein and Jaffe in 1942 represent approximately 5% to 7% of benign bone tumors A sporadic disorder of osseous and fibrous tissue development characterised by postzygotic mutation of GNAS1 gene coding for stimulatory G protein. Analysis of the Gs ? subunit in patients with fibrous […]
