Comparative StudyAdolescent idiopathic scoliosis treated by Harrington-rod distraction and fusion.
One hundred and thirty-three patients who had adolescent idiopathic scoliosis were treated by insertion of a single Harrington distraction rod and spinal fusion. Postoperative immobilization consisted of six months in a below-the-shoulder cast. The mean preoperative curve was 50 degrees, with a range of 30 to 110 degrees. ⋯ Twelve patients required further surgery for complications, all of which were treated successfully. The duration of follow-up ranged from twenty-four to seventy-two months. At final follow-up, all patients had resumed their normal preoperative activities without limitations.

Eighteen patients with tibial fractures treated by plating that had failed were treated by intramedullary nailing. Nine patients had a broken plate or screw that had pulled out. In seven, the plate and screws were intact but no healing was evident, and in two patients the plate was intact but one or more screws were broken. ⋯ In one patient the method failed, while in fifteen patients the fracture united and in the two remaining patients who could not be contacted union was thought to be in process when they were last seen, five and ten months postoperatively. Two bone grafts were used in one patient. Six fibular osteotomies were performed in conjunction with the intramedullary nailing.

Comparative StudyA comparative study of the tolerance of skeletal muscle to ischemia. Tourniquet application compared with acute compartment syndrome.
In this study, the tolerance of skeletal muscle to tourniquet application (ischemia) and to acute compartment syndrome (ischemia and pressure) was compared. In five animals, the cuff of a pneumatic tourniquet was inflated to 350 millimeters of mercury at the level of the thigh for three hours. In five other animals, an acute experimental compartment syndrome was created in one anterolateral compartment by autologous plasma infusion. ⋯ In contrast, the levels of adenosine triphosphate diminished rapidly in the animals with the compartment syndrome, but remained unchanged in the tourniquet group. Ischemic muscle acidosis was more severe in dogs with the compartment syndrome. In the tourniquet group, the phosphocreatine, adenosine triphosphate, and pH were all normal within fifteen minutes after release of the tourniquet, but these values remained depressed even two hours after fasciotomy in the group with compartment syndrome.(ABSTRACT TRUNCATED AT 250 WORDS)
