Department of Anesthesiology and Pain Medicine, Soonchunhyang University, Seoul Hospital, Seoul, Republic of Korea.

Rationale: Variant angina is characterized by coronary artery spasm irrespective of the presence of fixed stenotic coronary lesions. Perioperative coronary artery spasm may be induced by the supersensitivity of vascular smooth muscle cells caused by various stimuli, including stimulation of the parasympathetic nervous system.

Patient Concerns: A 57-year-old male patient was undergoing arthroscopic rotator cuff repair under combined interscalene brachial plexus block and general anesthesia in the lateral decubitus position. Read More

Medicine (Baltimore) 2019 Feb;98(5):e14264

Department of Orthopaedic Surgery, Soonchunhyang University Hospital Cheonan, Cheonan, Korea.

Rationale: Adequate stability of traumatic anterior shoulder dislocation without any obvious damage to the anterior capsulolabral structure in elderly patients can be achieved by treating the associated rotator cuff injuries. However, in case of recurrent shoulder dislocation despite rotator cuff repair, the repaired rotator cuff may be weakened or reruptured and is often impossible to repair again. Therefore, the role of the rotator cuff as a shoulder stabilizer cannot be expected. Read More

Tendon injuries often require surgical intervention and even then result in poor outcomes due to scar formation and repeated failure. Biomaterial implants offer the potential to address multiple underlying concerns preventing improved tendon repair. Here, we describe modifications to the composition of an anisotropic collagen-glycosaminoglycan (CG) scaffold biomaterial, incorporating amniotic membrane (AM)-derived matrix to alter the inflammatory response and establish conditions for improved regenerative repair.

Purpose: Poor healing of the tendon-bone interface (TBI) after rotator cuff (RTC) tears leads to high rates of recurrent tear following repair. Previously, we demonstrated that an injectable, thermoresponsive, type I collagen-rich, decellularized human tendon-derived hydrogel (tHG) improved healing in an acute rat Achilles tendon injury model. The purpose of this study was to investigate whether tHG enhances the biomechanical properties of the regenerated TBI in a rat model of chronic RTC injury and repair. Read More

Department of Orthopaedics, University of Zurich, Balgrist University Hospital, Zurich, Switzerland; Laboratory for Orthopaedic Biomechanics, ETH Zurich, Zurich, Switzerland.

Aims: In patients with a rotator cuff tear, tear pattern and tendon involvement are known risk factors for the development of pseudoparalysis of the shoulder. It remains unclear, however, why similar tears often have very different functional consequences. The present study hypothesizes that individual shoulder anatomy, specifically the moment arms (MAs) of the rotator cuff (RC) and the deltoid muscle, as well as their relative recruitment during shoulder abduction, plays a central role in pseudoparalysis.

Department of Orthopaedics, Leiden University Medical Center, the Netherlands. Electronic address:

Rotator cuff muscle atrophy is frequently studied, but it is unknown whether redistribution of mechanical load in the presence of a rotator cuff tear influence muscle atrophy that is observed in patients. We hypothesized that in the presence of a supraspinatus tear, redistribution of mechanical load towards teres minor and deltoid slows down atrophy of these muscles over time. In this retrospective observational study of 129 patients, we measured the cross-sectional surface-areas on MRI of shoulder muscles in an intact rotator cuff (n = 92) and in a supraspinatus-tear group (n = 37) with a mean follow-up of 3 ± 1.

Distal triceps ruptures are uncommon injuries resulting in loss of elbow extension strength and necessitating surgical repair to ensure optimal functional outcome. Traditional fixation techniques using running, locking sutures through the tendon secured through bone tunnels have been shown to poorly restore the anatomic footprint and are mechanically inferior to anatomic repairs. We endorse restoring the anatomic footprint of the distal triceps, similar to the well-researched rotator cuff repair model. Read More
