Autogenous vascularized and nonvascularized total joint transfers were studied in the hands of Macaca fascicularis monkeys. Nine second toe proximal interphalangeal joints were transferred as a vascularized free graft to the hand, and the excised finger joints were transferred to the foot as a nonvascularized free graft. The grafts were examined clinically and histopathologically at 16 weeks to 10 months. Two of the nonvascularized free grafts were amputated because of infection and necrosis. Three had chronic infections. The four surviving nonvascularized grafts demonstrated necrosis of the hyaline cartilage and degenerative changes. Of the nine vascularized joints, one developed a wound infection that required amputation, another failed at 2 weeks because of wound dehiscence, and the remaining seven survived with preservation of the hyaline articular surfaces. The experimental technique was designed to be easily applied to clinical use. A skin island is provided as a "patency/viability monitor." The extensor mechanism is included in the graft for early function. 相似文献

Nine infants underwent operations for perforation of a Meckel's diverticulum over a 21-yr period. All of the infants were acutely ill when initially seen by the surgical service. Lethargy, irritability, anorexia, fever, abdominal tenderness, and passage of blood in the stools were common clinical manifestations. The preoperative diagnosis of perforated Meckel's diverticulum was not made in any of the cases. Skilled preoperative and postoperative management is important for the survival of these infants. There was no mortality and minimal morbidity. In retrospect, the peptic etiology of perforation in this age group is a key to early recognition. The past history of most of the patients includes previous episodes of blood in the stools and episodic abdominal complaints. 相似文献
