conclusions the use of an achilles tendon allograft provides excellent results in complex distal triceps tendon ruptures. we report the use of a new technique to anchor a distal achilles allograft. introduction the distal triceps tendon rupture is an uncommon injury. the acute treatment is well-defined, but when a delayed diagnosis is made or when a tendon retraction is present the alternatives...

Tendon-driven robots, where one or more tendons under tension bend and manipulate a flexible backbone, can improve minimally invasive surgeries involving difficult-to-reach regions in the human body. Planning motions safely within constrained anatomical environments requires accuracy efficiency shape estimation collision checking. Tendon robots that employ arbitrarily-routed achieve complex int...

In this paper we show a method for identifying ligament tears in MRI scans. We present a new algorithm that builds a spatial pyramid over the tendon invariant to scale and orientation changes of the tendon. We analyze the performance of both LLC encoded texton features and Intensity histograms for building extracting features from the pyramid regions. Figure 1. A cropped MRI of a damaged Patell...

Swan neck thumb deformity can be caused by osteoarthritis, rheumatoid arthritis, systemic lupus erythematosus, tendon transfers and paralytic diseases. Abductor pollicis longus is one of the major stabilizing tendon of the carpometacarpal joint of thumb. To the best of our knowledge, swan neck thumb deformity owing to division of abductor pollicis longus tendon is rare. In this article, we desc...

The theory of acoustic, electromagnetic and elastic wave fields in terms of governing equations, plane waves, spherical waves (Green functions) and scattered field representations is discussed under common aspects leading to a unified derivation of modeling and imaging algorithms. The latter require a linearization of the inverse scattering problem. Applications referring to the location and as...

Article history: Received 29 April 2015 Received in revised form 23 August 2015 Accepted 30 August 2015 Available online 14 September 2015 Snake-like flexible manipulators are widely used in minimally invasive surgery (MIS), which require adequate dexterity in confined workspace. Typically, the design mechanisms of these manipulators include tendon-driven mechanism and concentric tube mechanism...
