Are clinical outcomes of frozen shoulder linked to pain, structural factors or pain-related cognitions? An explorative cohort study.

Background: In frozen shoulder (FS), inflammatory-fibrotic adaptations in capsuloligamentous structures are typically linked to perceived glenohumeral stiffness, glenohumeral range of motion (ROM) restrictions and decreased arm function. However, ROM restrictions based on muscle guarding are suggested as well.

Objectives: To assess differences between pain, perceived stiffness, ROM restrictions and arm function at time of diagnosis and at four months follow-up and to assess whether perceived stiffness, ROM restrictions and arm function relate to pain, structural and/or cognitive factors.

Prebending of osteosynthesis plate using 3D printed models to treat symptomatic os acromiale and acromial fracture.

Background: A symptomatic os acromiale can lead to impingement syndrome and rotator cuff tendinopathy. An acromion fracture is often part of a more complex scapular trauma that needs stabilisation.

Methods: We developed a new technique using a three-dimensional (3D) model and a distal clavicle reconstruction plate to treat os acromiale and acromion fractures.

From Bone Marrow to Cardiac Atrial Appendage Stem Cells for Cardiac Repair: A Review.

Traditionally the heart is considered a terminally differentiated organ. However, at the beginning of this century increased mitotic activity was reported in ischemic and idiopathic dilated cardiomyopathy hearts, compared to healthy controls, underscoring the potential of regeneration after injury. Due to the presence of adult stem cells in bone marrow and their purported ability to differentiate into other cell lineages, this cell population was soon estimated to be the most suited candidate for cardiac regeneration.

Cardiac atrial appendage stem cells engraft and differentiate into cardiomyocytes in vivo: A new tool for cardiac repair after MI.

Background: This study assessed whether autologous transplantation of cardiac atrial appendage stem cells (CASCs) preserves cardiac function after myocardial infarction (MI) in a minipig model.

Methods And Results: CASCs were isolated from right atrial appendages of Göttingen minipigs based on high aldehyde dehydrogenase activity and expanded. MI was induced by a 2h snare ligation of the left anterior descending coronary artery.

Recovery of regional but not global contractile function by the direct intramyocardial autologous bone marrow transplantation: results from a randomized controlled clinical trial.

Background: Recent trials have shown that intracoronary infusion of bone marrow cells (BMCs) improves functional recovery after acute myocardial infarction. However, whether this treatment is effective in heart failure as a consequence of remodeling after organized infarcts remains unclear. In this randomized trial, we assessed the hypothesis that direct intramyocardial injection of autologous mononuclear bone marrow cells during coronary artery bypass graft (CABG) could improve global and regional left ventricular ejection fraction (LVEF) at 4-month follow-up.

An unusual metallic foreign body in the lateral tibiofemoral compartment.

A child presented with pain and swelling of the knee caused by a fall on the snow. Medical imaging showed an unusual metallic foreign body in the lateral tibiofemoral compartment. Arthroscopy revealed the nature of the foreign body; a metallic piece of stone had penetrated skin and cartilage and was fastened in the cartilage of the lateral femoral condyle where it caused damage to the cartilage and the anterior horn of the lateral meniscus.
