A suitable plastic, a rigid polyurethane foam (Ostamer *), which can be poured in liquid form and has properties of strength, osteogenesis, nontoxicity, cohesiveness, and ease of handling at surgery, has been used by us in 35 cases to date. It is the purpose of this paper to review these cases. Ostamer is the most extensively studied plastic used to date in the human body. Experiments have been progressing for four years to ascertain the toxicology, absorption, metabolic route of excretion, osteogenetic properties, and strength potential of Ostamer. Without reservation it can now be stated that Ostamer has the strength per square inch and the adhesiveness necessary for bone fixation, and it also provides a chemical lacunar system (Fig. 1). New bone, a notorious creeper when given a suitable medium, not only climbs along the surface, but grows through the plastic, as would be expected with an autogenous graft. This, therefore,
Introduction A review of the literature on x-ray visualization of the intervertebral disc has led to two conclusions. First, there is a definite need for a detailed account of the technique of disc puncture. Second, the x-ray discogram should be more clearly illustrated since its interpretation could then be more readily understood and coordinated with the clinical picture of low-back pain. The material for this report is based on experiences while working with Feffer.5,6 There is a need for a more accurate method of diagnosis of intervertebral disc pathology. Although helpful, myelography can be confusing and misleading.21Discography, devised by Lindblom,14-20eliminates some of these difficulties and is more accurate as an indicator of intervertebral disc pathology.1-5,9,24,26It gives information that myelography cannot,1,2,5,9e.g., lateral disc. Furthermore, minimal routine x-ray changes are more easily evaluated and correlated with the patient's symptomatology. Discography is not the
The patient with cirrhosis of the liver and bleeding esophageal varices presents a number of serious problems. Diagnosis may occasionally be difficult and the treatment hazardous whether by balloon tamponade or transesophageal ligation. If the patient survives the acute bleeding episode, a period of intensive treatment is necessary to attain a maximum return toward normal liver function. Having accomplished this, an operation of considerable magnitude, frequently under prolonged anesthesia, must be performed. The postoperative period is endangered, in addition to the usual complications, by those untoward events peculiar to this disease, such as liver failure, coma, ammonia intoxication, and hemorrhage. Therefore, any treatment or technique which will enhance the possibility of recovery assumes a degree of importance. This discussion concerns the utilization of hypothermia during anesthesia for portacaval shunt. The Rationale of Hypothermia Linton (1958), one of the pioneers in shunt surgery, has described on several occasions his preference for
