We report a case of pulley rupture following repeated local corticosteroid injections for trigger digit. The treatment involved exploration, tenolysis, and reconstruction using the palmaris longus tendon.

Transmission on the vehicle is very important component to ensure maximum power transfer from engine wheels. The speed of four-wheeled vehicles influenced by transmission system used. Pulley continuous variable (CVT) which currently widely used in automotive industry. CVT type automatic with gearshift process that does not use gears, but uses pulley. pulley made stainless steel. For there are t...

PURPOSE Soft pulleys stabilize paths and determine pulling directions of the extraocular muscles (EOMs). This study was conducted to characterize innervation of smooth muscles (SMs) supporting these pulleys. METHODS Cadaveric human and monkey orbits were step and serially sectioned for histochemical and immunohistochemical staining. Before perfusion, the superior cervical ganglia of one monke...

is a time-consuming and technically demanding technique [1–3]. The main difficulty is the lack of triangulated countertraction with current endoscopes [4]. To improve speed and efficacy of the procedure, an intriguing pulley method using dental floss together with endoscopic clips has recently been described [5]. However, current clip technology is unlikely to provide a robust and dependable an...

The purpose of this retrospective study was to compare the outcomes and complications of conventional open surgical release and percutaneous needle release in the treatment of trigger thumb. The study comprised 87 patients with trigger thumb who were treated with either open pulley (n=52) or percutaneous (n=32) release between 2008 and 2011. All patients were reevaluated at a mean follow-up of ...

Atwood’s machine is presented in introductory physics courses as an exercise in the simultaneous solution of Newton’s second law for translational and rotational motions, assuming the pulley has nonnegligible mass. Occasionally it is also used as a lecture demonstration or for quantitative laboratory measurements of a system undergoing constant acceleration. As discussed in this paper, one can ...

Abstract In this work, a planar cable parallel robot (CPR) driven by four cable-and-pulley differentials is proposed and analyzed. A new differential designed adding an extra pulley to eliminate the modeling inaccuracies due radius obviate need of solving complex model which considers kinematics. The design parameters CPR are determined through multi-objective optimal for largest total orientat...
