Outcome After Reconstruction of the Proximal Humerus for Tumor Resection: A Systematic Review

Teun Teunis MD, Sjoerd P. F. T. Nota MD, Francis J. Hornicek MD, PhD, Joseph H. Schwab MD, MS, Santiago A. Lozano-Calderón MD, PhD

Tumors of the appendicular skeleton commonly affect the proximal humerus, but there is no consensus regarding the best reconstructive technique after proximal humerus resection for tumors of the shoulder.

Relative Fixation Strength of Rabbit Subscapularis Repair Is Comparable to Human Supraspinatus Repair at Time 0

Karimdad Otarodifard MD, Jeffrey Wong MD, Charles F. Preston MD, James E. Tibone MD, Thay Q. Lee PhD

Recent evidence suggests that the rabbit subscapularis tendon may be anatomically, biomechanically, and histologically suitable to study rotator cuff pathology and repair. However, biomechanical comparisons of rotator cuff repairs in this model have not been evaluated and compared to those in human cadaveric specimens.

Remplissage Versus Latarjet for Engaging Hill-Sachs Defects Without Substantial Glenoid Bone Loss: A Biomechanical Comparison

Ryan M. Degen MD, Joshua W. Giles BESc, James A. Johnson PhD, George S. Athwal MD, FRCSC

Recurrent shoulder instability is commonly associated with Hill-Sachs defects. These defects may engage the glenoid rim, contributing to glenohumeral dislocation. Two treatment options to manage engaging Hill-Sachs defects are the remplissage procedure, which fills the defect with soft tissue, and the Latarjet procedure, which increases glenoid arc length. Little evidence exists to support one over the other.

External Rotation Immobilization for Primary Shoulder Dislocation: A Randomized Controlled Trial

Daniel B. Whelan MD, MSc, Robert Litchfield MD, Elizabeth Wambolt BSc(HK), CCRP, Katie N. Dainty PhD

The traditional treatment for primary anterior shoulder dislocations has been immobilization in a sling with the arm in a position of adduction and internal rotation. However, recent basic science and clinical data have suggested recurrent instability may be reduced with immobilization in external rotation after primary shoulder dislocation.

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.
