Three-dimensional scapular morphology is associated with rotator cuff tears and alters the abduction moment arm of the supraspinatus.

Clin Biomech (Bristol, Avon) 2020 Jun 11;78:105091. Epub 2020 Jun 11.

Department of Mechanical and Materials Engineering, Queen's University, Kingston, ON, Canada.

Background: Numerous studies have reported an association between rotator cuff injury and two-dimensional measures of scapular morphology. However, the mechanical underpinnings explaining how these shape features affect glenohumeral joint function and lead to injury are poorly understood. We hypothesized that three-dimensional features of scapular morphology differentiate asymptomatic shoulders from those with rotator cuff tears, and that these features would alter the mechanical advantage of the supraspinatus.

Posterior Labral Injury and Glenohumeral Instability in Overhead Athletes: Current Concepts for Diagnosis and Management.

J Am Acad Orthop Surg 2020 May 13. Epub 2020 May 13.

From the Department of Orthopaedic Surgery, San Antonio Military Medical Center, San Antonio, TX (Dr. Sheean); Lexington Clinic Orthopaedics, Sports Medicine Center, Lexington, KY (Dr. Kibler); Orthopaedic Specialty Associates, Fort Worth, TX (Dr. Conway); and the Department of Orthopaedic Surgery (Dr. Bradley), University of Pittsburgh, Pittsburgh, PA.

Posterior glenohumeral instability in overhead athletes presents a unique set of challenges for both diagnosis and treatment. Although a great deal of attention has been focused on the management of injuries to the biceps-labrum complex and rotator cuff in throwers, comparatively less has been written about posterior glenohumeral instability within this unique cohort. Historically, posterior instability has been observed secondary to either acute trauma or repetitive microtrauma, usually among collision athletes, weight lifters, and rowers. Read More

Ultrasound-guided platelet-rich plasma injection for the treatment of recalcitrant rotator cuff disease in wheelchair users with spinal cord injury: A pilot study.

J Spinal Cord Med 2020 May 7:1-7. Epub 2020 May 7.

Department of Physical Medicine and Rehabilitation, Rutgers New Jersey Medical School, Newark, New Jersey, USA.

Wheelchair users with spinal cord injury (SCI) have a high risk of developing shoulder pain, caused by rotator cuff disease. Platelet-rich plasma (PRP) is a potential treatment after conservative treatments fail and prior to surgical intervention; however, it has not been tested in wheelchair users who have recalcitrant shoulder pain associated with rotator cuff disease. The objective of this pilot project was to test the safety and potential treatment effect of an ultrasound-guided PRP injection for shoulder pain in the aforementioned population. Read More

Editorial Commentary: Bone Marrow Aspirate Concentrate Harvested From the Ilium During Acetabular Labral Repair: Is the Biologic Juice Worth the Squeeze?

Arthroscopy 2020 05;36(5):1321-1322

Keck School of Medicine of the University of Southern California.

The use of regenerative technologies including mesenchymal stromal cells, also known as connective tissue progenitors (CTPs), has gained tremendous popularity as a primary and adjuvant treatment for many musculoskeletal conditions. The concentration of bone marrow-derived CTPs delivered to the site of injury has been directly correlated to the therapeutic effect in the setting of rotator cuff repair and the healing of long-bone fractures. In addition, there has been some limited in vitro and in vivo evidence to suggest that the delivery of bone marrow-derived CTPs may improve cartilage regeneration. Read More
