Quantification of radial torsion angle with computerized tomography: a clinical study.

Our objective is to assess the utility of the radial torsion angle (RTA) as described by Bindra et al. in the clinical setting among patients with previous distal radial fractures compared to normal controls [4]. We hypothesize that the side-to-side RTA difference will be increased in subjects with previous forearm fracture as compared to normal subjects.

Subluxation of the distal radioulnar joint as a predictor of foveal triangular fibrocartilage complex tears.

Purpose: The triangular fibrocartilage complex (TFCC) with its ulnar foveal attachment is the primary stabilizer of the distal radioulnar joint (DRUJ). The purpose of this study was to describe a technique for measuring the degree of subluxation of the DRUJ in wrist magnetic resonance imaging (MRI) examinations to predict tears involving the foveal attachment of the TFCC.

Methods: We measured DRUJ geometry in wrist MRI examinations of 34 patients who were found to have foveal TFCC tears at surgery.

Efficacy of diagnostic magnetic resonance imaging for articular cartilage lesions of the glenohumeral joint in patients with instability.

Objective: The purpose of this study was primarily to assess the diagnostic performance of magnetic resonance imaging (MRI) in detecting articular cartilage injuries in patients with glenohumeral instability. A secondary purpose was to assess the diagnostic performance of MRI for detection of Hill-Sachs and Bankart lesions.

Materials And Methods: A cohort of 87 consecutive patients who underwent diagnostic MRI and shoulder arthroscopy for instability from 1997 to 2006 were identified.

Pathologic correlation of posterior ligamentous injury with MRI.

This article describes 2 cases of spinal trauma in which diagnostic magnetic resonance imaging (MRI) was correlated with histopathology for diagnosis of a posterior ligamentous complex injury. Spine fractures are common and represent up to 16% of traumatic fractures. Diagnostic imaging currently involves plain films and computerized tomography, but MRI is being used with increasing frequency.
