Neurosonographic changes in newborns treated with extracorporeal membrane oxygenation.

Ten out of 40 near-term neonates on extracorporeal membrane oxygenation (ECMO) therapy developed abnormal neurosonograms. We identified two abnormal patterns. Hyperechoic areas of intracranial hemorrhage were observed in two patients (a significantly lower incidence than previously reported). Diffuse or focal echogenic areas of hypoxia-ischemia resulting from periventricular leukomalacia, cerebral edema or large vessel infarction had not previously been noted in nine of these patients. Three of the ten patients survived with neurological sequelae. Recognition of hemorrhage or a hypoxic-ischemic pattern should serve as a warning to initiate or accelerate the weaning of infants from ECMO.

Arthrography in the diagnosis of fractures of the distal end of the humerus in infants.

Single-contrast arthrography was performed in six infants who had an injury to the elbow because the exact nature of the injury was uncertain from interpretation of the plain radiographs and clinical findings. A correct diagnosis was made in all six patients, and it significantly altered the treatment in five. Four lesions were a Salter-Harris Type-I fracture and two were a Salter-Harris Type-II fracture. Three patients had a closed reduction, two required no reduction, and one had an open reduction. Child abuse of two infants was confirmed, and it was suspected in another two.

Some vagaries of the medial epicondyle.

Roentgenographic data on the maturing epiphysis of the medial epicondyle of the humerus are prone to misinterpretation for the following reasons. First, fractures of the medial epicondyle may not be associated with joint effusion or metaphyseal avulsion fragments. Second, in the medial epicondyle the center of ossification, which lies posteromedial to the distal end of the humerus and is the last of the elbow epiphyses to unite with the humerus, may be quite distant from the humeral metaphysis, and differentiation of this normal characteristic from minimum avulsion is necessary. Also, multicentric ossification, although uncommon, will give the epiphysis a fragmented appearance. Finally, just before ossification of the medial epicondylar epiphysis, on its metaphyseal surface on the distal end of the humerus a sharp, straight sclerotic edge develops.

Some vagaries of the olecranon.

The maturing olecranon of the ulna is readily prone to misinterpretation because its normal radiographic characteristics may closely resemble those of fractures, for the following reasons: (1) just prior to ossification of the olecranon epiphysis, a straight sclerotic edge develops in the associated metaphysis on the proximal part of the ulna; (2) ossification of the olecranon begins in two or more centers that commonly fuse with each other before fusing with the parent bone and that may be separated widely from the metaphysis in the early stages; and (3) the physis of the olecranon frequently migrates distally into the joint and may simulate a fracture line. Features distinguishing the normal olecranon from a fracture are discussed in this paper.
