We describe a three-year-old boy who had spontaneous regeneration of the entire lateral malleolus after injury, including the epiphysis, physis and metaphysis.

During hominin evolution, an increase in the femoral bicondylar angle was the initial change that led to selection for protuberance of the lateral trochlear lip and the elliptical profile of the lateral condyle. No correlation is found during ontogeny between the degree of femoral obliquity and of the prominence of the lateral trochlear lip. Might there be a relationship with the elliptical pro...

BACKGROUND The report presents the authors' experience with Fassier-Duval rods in children and an analysis of advantages and complications. MATERIAL AND METHODS Over a period of 15 months, the authors operated on 10 children and 18 rod implantation procedures were performed. In five cases, the implantation was a primary procedure, while in the remaining 13 cases Fassier-Duval rods were used t...

Hormonal influence resulting from serum gonadotropin was investigated by radiochemical activity studies of the degradation enzyme of monoamine oxidase catecholamines (MAo) in certain regions of the hypothalamus (area preoptica, corpus mamillare, infundibulum), which participates in the regulation of sheep sexual functioning, as well as in nucleus caudatus, in the hypophysis and epiphysis. We at...

Although previous theoretical modeling studies have predicted that various mechanical stresses accelerate or inhibit the ossification process of the neonatal chondroepiphysis, there is a paucity of experimental data to verify these models. The present study was designed to provide experimental evidence on whether the ossification of the chondroepiphysis is modulated by mechanical loading on the...

BACKGROUND Using a too big or a too small size of an endotracheal tube in pediatric patients would result in tracheal injury or insufficient ventilation. Determining the appropriate endotracheal tube size is important because using an inappropriate size can cause complications. This study was performed to predict the appropriate endotracheal tube size by measuring the transverse diameter of the...
