PURPOSE Deformities of the forearm and shortening of the ulna occur in 30 % of patients with hereditary multiple exostoses (HME), leading to radial head dislocation and loss of movement. Several surgical techniques have been described for treatment, and the aim of our study was to present clinical and radiographic results at skeletal maturity in 15 children that underwent the surgical procedure...

Background Clinical studies have shown that many patients may have abnormally reduced myocardial shortening despite preserved ejection fraction (EF). Mathematical modeling explains this apparent paradox by demonstrating, that whilst myocardial shortening determines radial strain (RS), it is absolute wall thickness (AWT) rather than RS that determines EF. We sought in vivo cardiac MR (CMR) evide...

Aponeuroses are sheet-like elastic tendon structures that cover a portion of the muscle belly and act as insertion sites for muscle fibers while free tendons connect muscles to bones. During shortening contractions, free tendons are loaded in tension and lengthen due to the force acting longitudinally along the muscle׳s line of action. In contrast, aponeuroses increase in length and width, sugg...

BACKGROUND The effectiveness of excision of osteochondromas in controlling the progression of forearm and wrist deformity remains an issue of controversy. The purpose of this study was to analyze the effectiveness of tumor excision in the correction of forearm and wrist deformity due to multiple osteochondromas in children, with an interpretation of the results based on different patterns of de...

Seven fresh cadaveric specimens were used to determine the loss of forearm rotation with varying distal radius fracture malalignment patterns. Uniplanar malunion patterns consisting of dorsal tilt, radioulnar translation, or radial shortening were simulated by creating an osteotomy at the distal end of the radius, orienting the distal fragment position using an external fixator, and maintaining...

congenital radial club hand is an intercalary or terminal deficiency characterized by radial deviation of the hand, marked shortening of the forearm, and generalized underdevelopment of the extremity. we performed centralization of the ulna in 12 forearms of 10 patients with severe congenital radial club hands. the mean follow up was 42 months after operation (24 to 68 months). the mean age at ...

To determine whether regional wall motion abnormalities exist or contribute to left ventricular dysfunction, we obtained two-dimensional echocardiograms in 12 athletes before (baseline), immediately after (race finish), and 1 day after (recovery) the Hawaii Ironman Triathlon (a 3.9-km swimming, 180.2-km bicycling, and 42.2-km running event). Left ventricular short-axis and apical four-chamber v...
