This study investigates the performance of a 3 D Ultrasound (US) system in imaging elbow and wrist nerves. ⋯ 3DUS is a feasible method for assessing nerves of the upper extremity and has been shown to provide a good overview of the median, ulnar and radial nerve at the elbow and wrist, but is limited for evaluation of the ulnar nerve in the cubital tunnel. This technique enables reliable measurements at different locations along the nerve.

Extensive wound defects frequently have to be covered by free flap transplantation. A monitoring device for measuring capillary level perfusion of bone is currently not available. ⋯ CEUS seems to be capable of detecting vascular disturbances and of assessing microvascularization of the osseous component after osteocutaneous flap transplantation.

Randomized Controlled Trial Comparative Study
Prospective comparison of noninvasive, bedside ultrasound methods for assessing central venous pressure.
To prospectively evaluate the accuracy of noninvasive central venous pressure (CVP) assessment by compression ultrasound of a forearm vein (CUS), inferior vena cava (IVC-C) and internal jugular vein collapsibility (IJV-C) compared to invasive CVP measurement (invCVP) as the gold standard. ⋯ The overall ability of CUS, IVC-C and IJV-C to assess invCVP was only moderate. CUS seems to be the preferable method if absolute CVP values are needed. IJV-C seems to be the fastest and most easily acquirable method, and thus may be especially valuable in emergency rooms.

The aim of the current study was to evaluate an ultrasound approach for depicting elastic recovery after stem cell application on injured Achilles tendons. ⋯ Our results indicate that autologous mesenchymal stem cell application successfully restores the mechanical properties of injured tendon tissue. Furthermore, sonoelastography makes it possible to monitor the elasticity of injured Achilles tendons.
