Isotope scanning with Tc99m-MDP of the spine and the costosternal junctions of patients with idiopathic scoliosis.
Bone scanning of the thoracolumbar spine and the anterior thorax was performed in 7 girls with recently diagnosed progressive thoracic idiopathic scoliosis. A reference group consisted of a group of 8 patients submitted to bone scanning for other reasons. In all 7 girls composing the scoliosis group the isotope uptake by the vertex vertebra, the 2 vertebrae above and the 2 below was homogeneous, with no areas of abnormally increased uptake. In 5 of these patients where quantitative studies were performed there was no significant difference in uptake between the vertex and the other 4 vertebrae. Nor did the 2 groups differ significantly as regards the left-right difference in uptake by the costosternal junctions. The results of this investigation confirm the observation in a preliminary study that there was no disturbance of spinal growth during the early stage of development of idiopathic thoracic scoliosis. However, the results do not support a tentative conclusion drawn on the basis of the preliminary study--namely, that the development of spinal deformity in idiopathic scoliosis might be ascribed to asymmetric longitudinal rib growth, reflected in asymmetric isotope uptake by the paired costosternal junctions. It is questionable however, whether scintigraphic scanning can provide an accurate procedure for quantitative measurement of skeletal growth of the ribs, especially in scoliotic patients.

Avascular necrosis of the bone in 99 renal allograft recipients.
Avascular necrosis of bone is a serious complication associated with steroid therapy in high dose. Ninetynine patients with functioning renal allografts transplanted 1964-1973 and subjected to steroid therapy were examined with regard to this complication. Osteonecrosis developed in 8 patients afflicting 13 joints. The process was localized to the femoral head, the condyles of the femur, tibia and the head of the humerus. The symptoms became manifest 7-33 months after the first transplantation. The severity of the disorder in 3 patients did not allow rehabilitation by conservative means. The roentgenographic, scintigraphic and clinical findings are described and the orthopaedic treatment discussed.

Pancreatic transplantation for diabetes mellitus. Discussion of indications and surgical technique with reference to 3 cases.
Three patients reveived segmental pancreatic transplants. In two the main indication was hyperlabile diabetes, and in the third progressive loss of vision. Vascular anastomoses were to the iliac vessels, the graft being placed extraperitoneally. The pancreatic duct was ligated in the first case, while the other two, the transected end of the pancreatic graft was implanted into a jejunal Roux-Y loop. Two of the patients had normal blood glucose levels without insulin administration for 40 and 35 days, respectively. The grafts then underwent rejection and were removed. In both cases the postoperative course was complicated by pancreatic fistulae. In the 3rd patient the graft failed on the day after operation, due to venous trombosis.
