Current reverse total shoulder arthroplasty prosthesis designs do not permit offset of the humerus in the sagittal plane. Posteriorly shifting the humerus has the theoretical benefit of lengthening the infraspinatus and teres minor muscles and their external rotation moment arms, thereby improving the tension and efficiency of each external rotator and subsequently requiring each muscle to prod...

PURPOSE To evaluate 2-year postsurgical safety and efficacy of canaloplasty (circumferential viscodilation and tensioning of the inner wall of Schlemm canal) to treat open-angle glaucoma (OAG). SETTING Multicenter surgical sites. METHODS This international prospective study comprised adult OAG patients having glaucoma surgery or combined glaucoma-cataract surgery. Qualifying preoperative in...

This study describes the results of a series 2D finite element method (FEM) numerical models 6 m high back-to-back reinforced soil walls using geotechnical software PLAXIS. These structures are used to support embankments, especially for bridge abutment approaches. The quantitative influence problem geometry, strip pre-tensioning, type, and surcharging on horizontal displacements, development s...

Twining plants use their helical stems to clasp supports and to generate a squeezing force, providing stability against gravity. To elucidate the mechanism that allows force generation, we measured the squeezing forces exerted by the twiner Dioscorea bulbifera while following its growth using time-lapse photography. We show that the development of the squeezing force is accompanied by stiffenin...

Anterior cruciate ligament (ACL) rupture predisposes to altered kinematics and possible knee joint degeneration. Graft fiber maturation and ligamentization may eliminate this risk during ACL reconstruction procedures. ACL remnant-sparing techniques support the theory that the preserved tissue enhances revascularization, preserves the mechanoreceptors, and leads to anatomic remodeling. The purpo...

BACKGROUND/AIMS To study the safety and effectiveness of 360° viscodilation and tensioning of Schlemm canal (canaloplasty) in black African patients with primary open-angle glaucoma (POAG). METHODS Sixty randomly selected eyes of 60 consecutive patients with POAG were included in this prospective study. Canaloplasty comprised 360° catheterisation of Schlemm's canal by means of a flexible micr...

BACKGROUND This study investigated whether a tensioning headband that applies up to 20 mmHg pressure over a forehead pulse oximetry sensor could improve arterial hemoglobin oxygen saturation reading accuracy in presence of venous pooling and pulsations at the forehead site. METHODS Healthy volunteers were studied breathing room air in supine and various levels of negative incline (Trendelenbu...
