Factors associated with operative treatment of enthesopathy of the extensor carpi radialis brevis origin.

Background: This study investigated the factors associated with variation in the rate of surgery for enthesopathy of the extensor carpi radialis brevis (eECRB).

Methods: We used a large database from 3 academic hospitals including 5964 patients with the diagnosis of eECRB from 2001 to 2007. Of those, 244 patients (4%) had surgery for eECRB.

Intraoperative Physical Examination for Diagnosis of Interosseous Ligament Rupture-Cadaveric Study.

Purpose: To study the intraobserver and interobserver reliability of the diagnosis of interosseous ligament (IOL) rupture in a cadaver model.

Methods: On 12 fresh frozen cadavers, radial heads were cut using an identical incision and osteotomy. After randomization, the soft tissues of the limbs were divided into 4 groups: both IOL and triangular fibrocartilage (TFCC) intact; IOL disruption but TFCC intact; both IOL and TFCC divided; and IOL intact but TFCC divided.

Imaging sensor constellation for tomographic chemical cloud mapping.

A sensor constellation capable of determining the location and detailed concentration distribution of chemical warfare agent simulant clouds has been developed and demonstrated on government test ranges. The constellation is based on the use of standoff passive multispectral infrared imaging sensors to make column density measurements through the chemical cloud from two or more locations around its periphery. A computed tomography inversion method is employed to produce a 3D concentration profile of the cloud from the 2D line density measurements.
