Dual-Energy CT Arthrography: Advanced Muscolo-Skelatal Applications in Clinical Practice.

This paper provides a comprehensive overview of the potential applications of dual-energy CT (DECT) in improving image quality and the diagnostic capabilities of CT arthrography (CTA) in clinical practice. The paper covers the use of virtual non-contrast (VNC) images, in which the injected contrast medium is subtracted from the articular cavity in order to better analyze 2D and 3D images of the bone. Moreover, virtual monoenergetic imaging (VMI) applications and their potential use for the reduction of metal artifacts and improving image contrast are reviewed.

Arthroscopic Superior Capsular Reconstruction (ASCR): All Soft Anchors Technique.

Rotator cuff tears are among the most common orthopaedic injuries. If not treated, they can result in a massive irreparable tear because of tendon retraction and muscle atrophy. Mihata et al.

Evaluation of glenoid labral tears: comparison between dual-energy CT arthrography and MR arthrography of the shoulder.

Objective: To compare the diagnostic accuracy of dual-energy computed tomography arthrography (DE-CTA) and magnetic resonance arthrography (MRA) of the shoulder in depicting glenoid labral tears.

Methods: This prospective institutional review board-approved study included 47 consecutive patients (28 males, 19 females; mean age of 34.2 years) studied between January 2017 and October 2018.

Prospective randomized controlled trial for patch augmentation in rotator cuff repair: 24-month outcomes.

Background: To evaluate the anatomic integrity of rotator cuff repair performed by medialized single row and augmented by a porcine dermal patch, in comparison with a nonaugmented group.

Methods: We conducted a single-center, prospective, double-blinded, randomized controlled trial. The sample size was predefined, and patients were divided into a study group and a control group, assessed preoperatively and at 1, 3, 6, 12, and 24 months.

Isolated Subscapularis Tendon Tear in a Skeletally Immature Soccer Player.

Subscapularis injury in adolescents, usually associated to an avulsion fracture of the lesser humeral tuberosity, accounts for less than 2% of all fractures of the proximal humerus. Isolated tears of the subscapularis tendon without a history of dislocation and associated avulsion fractures are an even rarer occurrence, and treatment is controversial. This article describes a rare case of a 12-year-old suffering from an isolated subscapularis tear and discusses its management.

MR arthrography of the shoulder: evaluation of isotropic 3D intermediate-weighted FSE and hybrid GRE T1-weighted sequences.

Purpose: To compare the diagnostic accuracy of three-dimensional (3D) fast spin echo (FSE) intermediate-weighed (IW-3D) and 3D hybrid double-echo steady-state T1-weighted sequences (Hy-3D) and two-dimensional (FSE) images (2D) at shoulder MR arthrography (MRA).

Materials And Methods: Institutional review board approval was obtained and informed consent was waived for this retrospective study. From September 2011 to October 2014, 102 patients who had undergone 1.

Reliability of forced internal rotation and active internal rotation to assess lateral instability of the biceps pulley.

Purpose: the aim of this study was to investigate the relationship between positive painful forced internal rotation (FIR) and lateral pulley instability in the presence of a pre-diagnosed posterosuperior cuff tear. The same investigation was conducted for painful active internal rotation (AIR).

Methods: a multicenter prospective study was conducted in a series of patients scheduled to undergo arthroscopic posterosuperior cuff repair.
