Clinical tests for assessing the presence and quality of the palmaris longus tendon: diagnostic accuracy of examination compared with ultrasound.

Various clinical tests are used to evaluate the palmaris longus tendon, but their accuracy is unknown. We assessed the accuracy of clinical tests (Schaeffer's, Thompson's, Mishra-I, Mishra-II) against ultrasound as the reference standard. We hypothesized that Schaeffer's was most accurate and that examination can reliably assess the palmaris longus tendon's length.

Fascicular constrictions above elbow typify anterior interosseous nerve syndrome.

Introduction: In this study we tested the hypothesis that fascicular constrictions (FCs) of the median nerve proximal to the elbow joint characterize anterior interosseous nerve syndrome (AINS).

Methods: Magnetic resonance neurography (MRN) and ultrasound (US) examinations were evaluated in 45 patients with clinically suspected AINS. All 22 patients at site 1 underwent MRN and 8 underwent US; all 23 patients at site 2 underwent US.

Self-identified functional limitations improve in patients with degenerative wrist arthritis after surgery.

Study Design: This is a prospective cohort pilot study.

Background: Degenerative wrist arthritis leads to pain, loss of strength, mobility, function, and impairments in psychological well-being. Accurate assessment of functional limitations that are unique to the individual is essential for successful treatment that best meets those specific needs.

An orbital shear platform for real-time, in vitro endothelium characterization.

Electrical impedance techniques have been used to characterize endothelium morphology, permeability, and motility in vitro. However, these impedance platforms have been limited to either static endothelium studies and/or induced laminar fluid flow at a constant, single shear stress value. In this work, we present a microfabricated impedance sensor for real-time, in vitro characterization of human umbilical vein endothelial cells (HUVECs) undergoing oscillatory hydrodynamic shear.
