Method and system for non-invasive determination of a pressure characteristic associated with carpal tunnel (CT) region of a subject. Speed of a shear wave induced in the tissue of the subject and propagating through the CT region is measured at least once. The pressure characteristic is substantially proportional to determined speed.

This document relates to methods and materials involved in tendon or ligament tissue engineering. For example, methods and materials for generating a composite of acellular tendon or ligament allograft slices seeded with cells and bundled into a graft for tissue repair are provided.

Tendon or ligament tissue engineering

A system and method is provided for using dynamic ultrasonic imaging to analyze a subject's carpal tunnel and generate risk factors indicative of the health of the subject's subsynovial connective tissue and the subject's risk of developing carpal tunnel syndrome. The system and method uses speckle imaging techniques to track dynamic structures within the carpal tunnel and statistical analysis techniques to compare the properties of these dynamic structures of the subject to those of normal subjects and subjects having carpal tunnel syndrome.

System and method for analyzing carpal tunnel using ultrasound imaging

This disclosure describes methods for detecting early stages of disease, in particular carpal tunnel syndrome, by using cooperative ultrasound techniques. In a particular embodiment, a grayscale ultrasonogram may be used to detect local anatomical features within the carpal tunnel by physically moving a tendon and identifying the corresponding feature on the ultrasonogram display device. A high-resolution color Doppler ultrasound device may then be used to interrogate features of anatomy surrounding the tendon for disease. In a particular embodiment, the color Doppler ultrasound device may be used to measure the velocities of the tendon and surrounding anatomy, in particular the sub-synovial connective tissue; the resultant data may be used to quantify certain anatomical anomalies, indicative or non-indicative of carpal tunnel syndrome.
