Biceps Detachment Decreases Joint Damage in a Rotator Cuff Tear Rat Model

Stephen J. Thomas PhD, ATC, Katherine E. Reuther BS, Jennica J. Tucker BS, Joseph J. Sarver PhD, Sarah M. Yannascoli MD, Adam C. Caro DVM, Pramod B. Voleti MD, Sarah I. Rooney MSE, David L. Glaser MD, Louis J. Soslowsky PhD

Pathology in the long head of the biceps tendon often occurs in patients with rotator cuff tears. Arthroscopic tenotomy is the most common treatment. However, the role of the long head of the biceps at the shoulder and the consequences of surgical detachment on the remaining shoulder structures remain unknown.

Effects of External Rotation on Anteroposterior Translations in the Shoulder: A Pilot Study

Andrew J. Brown BS, Richard E. Debski PhD, Carrie A. Voycheck PhD, Patrick J. McMahon MD

Using physical examination to make the diagnosis of shoulder instability can be difficult, because typical examination maneuvers are qualitative, difficult to standardize, and not reproducible. Measuring shoulder translation is especially difficult, which is a particular problem, because measuring it inaccurately may result in improper treatment of instability.

Deltoid-split or Deltopectoral Approaches for the Treatment of Displaced Proximal Humeral Fractures?

Benjamin Buecking MD, Juliane Mohr MD, Benjamin Bockmann, Ralph Zettl MD, Steffen Ruchholtz MD

Proximal humeral fractures are mainly associated with osteoporosis and are becoming more common with the aging of our society. The best surgical approach for internal fixation of displaced proximal humeral fractures is still being debated.

Does Preoperative American Society of Anesthesiologists Score Relate to Complications After Total Shoulder Arthroplasty?

Christine C. Johnson BA, Sonal Sodha MEng, Juan Garzon-Muvdi MD, Steve A. Petersen MD, Edward G. McFarland MD

For hip and knee arthroplasties, an American Society of Anesthesiologists (ASA) score greater than 2 is associated with an increased risk of medical and surgical complications. No study, to our knowledge, has evaluated this relationship for total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (reverse TSA).

Peripheral Nerve Blocks in Shoulder Arthroplasty: How Do They Influence Complications and Length of Stay?

Ottokar Stundner MD, Rehana Rasul MA, MPH, Ya-Lin Chiu MS, Xuming Sun MS, Madhu Mazumdar MA, MS, PhD, Chad M. Brummett MD, Reinhold Ortmaier MD, Stavros G. Memtsoudis MD, PhD, FCCP

Regional anesthesia has proven to be a highly effective technique for pain control after total shoulder arthroplasty. However, concerns have been raised about the safety of upper-extremity nerve blocks, particularly with respect to the incidence of perioperative respiratory and neurologic complications, and little is known about their influence, if any, on length of stay after surgery.

How Does External Rotation Bracing Influence Motion and Functional Scores After Arthroscopic Shoulder Stabilization?

Bob Yin MD, David Levy MD, Molly Meadows MD, Todd Moen MD, Prakash Gorroochurn PhD, Edwin R. Cadet MD, William N. Levine MD, Christopher S. Ahmad MD

After arthroscopic shoulder stabilization, the loss of motion or delayed recovery of motion remains a clinical problem and may lead to poor patient satisfaction. There remains no consensus regarding the optimal position for postoperative immobilization and it is not known whether the position for shoulder immobilization has an effect on motion and functional recovery.

Axillary View: Arthritic Glenohumeral Anatomy and Changes After Ream and Run

Frederick A. Matsen MD, Akash Gupta MD

The technique and results of shoulder arthroplasty are influenced by glenohumeral pathoanatomy. Although some authors advocate a routine preoperative CT scan to define this anatomy, ordering a CT scan substantially increases the cost and the radiation exposure for the patient.

Assessing Shoulder Motion in Children: Age Limitations to Mallet and ABC Loops

Michael L. Pearl MD, Fabian Bunt BS, Michaela Pearl BS, Nina Lightdale-Miric MD, Susan Rethlefsen PT, DPT, Jennifer Loiselle OTRL

Shoulder ROM and function of the shoulder are difficult to evaluate in young children. There has been no determination of the age at which children can comply with the current assessment tools in use, but doing so would be important, because it gives us more accurate insight into the development and assessment of shoulder functional ROM in young children.

Rotator Cuff Tear and Glenohumeral Instability

M. Mustafa Gomberawalla MD, Jon K. Sekiya MD

The rotator cuff plays a significant role in the static and dynamic stability of the glenohumeral joint. Rotator cuff tears may occur after shoulder dislocations, whether in younger athletes or older patients with age-related tendon degeneration. Untreated tears may cause persistent pain, dysfunction, instability, and degenerative changes. A thorough understanding of when to look for rotator cuff tears after shoulder dislocations and how best to manage them may decrease patients’ pain and improve function.

The Detrimental Effects of Systemic Ibuprofen Delivery on Tendon Healing Are Time-Dependent

Brianne K. Connizzo BS, Sarah M. Yannascoli MD, Jennica J. Tucker BS, Adam C. Caro DVM, Corinne N. Riggin BS, Robert L. Mauck PhD, Louis J. Soslowsky PhD, David R. Steinberg MD, Joseph Bernstein MD

Current clinical treatment after tendon repairs often includes prescribing NSAIDs to limit pain and inflammation. The negative influence of NSAIDs on bone repair is well documented, but their effects on tendon healing are less clear. While NSAIDs may be detrimental to early tendon healing, some evidence suggests that they may improve healing if administered later in the repair process.
