Avoiding iatrogenic vascular injury in tibial external fixation with half pins. An in-vivo study based on CT angiography.

Background: External fixation is an important tool in the management of variety of tibial fractures. Appropriate half pin insertion is important, to provide stable fixation without compromising the surgical field for definitive surgical procedures, and avoiding further damage to the important structures of the traumatized limb. There is paucity of literature about the optimal trajectories and safe corridors for half pins insertion based on in vivo studies.

3T MRI of wrist ligaments and TFCC using true plane oblique 3D T2 Dual Echo Steady State (DESS) - a study of diagnostic accuracy.

Objective: This study was designed to assess the accuracy of unenhanced 3T MRI supplemented with dedicated true plane reformats of 3D T2 Dual Echo Steady State (DESS), in assessing tears of scapholunate, lunotriquetral ligaments and triangular fibrocartilage complex, using arthroscopy as gold-standard.

Methods: In a retrospective cohort review, patients who underwent wrist arthroscopy and MRI over 2 years (n=46) were identified. Dedicated axial and coronal reformats were obtained from 3D T2 DESS sequence for assessing intrinsic ligaments and triangular fibrocartilage (TFCC).

The responsiveness of novel, dynamic, contrast-enhanced magnetic resonance measures of total knee synovitis after intra-articular corticosteroid for painful osteoarthritis.

Objective: Sensitive biomarkers are needed to understand synovial response to therapy in osteoarthritis (OA). Dynamic, contrast-enhanced magnetic resonance imaging (DCE MRI) provides quantitative, novel measures of synovial inflammation. This exploratory study examined DCE-assessed synovial response to intra-articular corticosteroid (IACS).

Magnetic resonance transverse relaxation time T2 of knee cartilage in osteoarthritis at 3-T: a cross-sectional multicentre, multivendor reproducibility study.

Objective: The transverse relaxation time (T2) in MR imaging has been identified as a potential biomarker of hyaline cartilage pathology. This study investigates whether MR assessments of T2 are comparable between 3-T scanners from three different vendors.

Design: Twelve subjects with symptoms of knee osteoarthritis and one or more risk factors had their knee scanned on each of the three vendors' scanners located in three sites in the U.

A randomized, double-blind, placebo-controlled trial of low-dose oral prednisolone for treating painful hand osteoarthritis.

Objective: Anti-inflammatory therapies are effective analgesics for OA. This study determined whether low-dose oral prednisolone (PNL) was an effective analgesic for hand OA.

Methods: This was a randomized, double-blind, placebo-controlled trial of people with ACR criteria hand OA and baseline hand pain visual analogue scale (VAS) of >40/100 mm.
