PURPOSE Tunnel widening after anterior cruciate ligament (ACL) reconstruction is a frequently described phenomenon. The possible etiology is multi-factorial with some mechanical and biological factors. Among those, we intended to determine the relation between the location and orientation of the femoral tunnel and the femoral tunnel enlargement after outside-in single-bundle ACL reconstruction....

Nine patients with myxoedema and carpal tunnel syndrome have been studied clinically and electrophysiologically to determine the presence or absence of the tarsal tunnel syndrome. Four patients had electrophysiological evidence of the tarsal tunnel syndrome, three of whom were mildly symptomatic. This would suggest that the tarsal tunnel syndrome is frequently encountered in myxoedema in associ...

Aorta-right atrial tunnel was diagnosed in a non-symptomatic 31-year old female patient. The Q p /Q s ratio was 2.5. Computed tomography and intraoperative views showed a posterior vascular tunnel with left aortic sinus and right atrium openings (Figs 1 and 2). The tunnel had no myocardial branches. We successfully closed both the openings. Figure 1: (A) A reconstructed computed tomographic vie...

INTRODUCTION: Clinical studies of carpal tunnel syndrome (CTS), a pressure-induced neuropathy of the median nerve, are limited by the difficulty of evaluating the early stages of pathology. Thus, a validated animal model of CTS is an important need. A proper animal model would have comparable anatomy to the human carpal tunnel. In addition, because carpal tunnel syndrome is characterized by inc...

Abstract. One promising design solution for increasing the efficiency of modern horizontal axis wind turbines is installation curved tip extensions. However, introducing such complex geometries may move traditional aerodynamic models based on blade element momentum (BEM) theory out their range applicability. This motivated present work, where a swept shape investigated by means both experimenta...
