Conversion of Stemmed Hemi- or Total to Reverse Total Shoulder Arthroplasty: Advantages of a Modular Stem Design

Karl Wieser MD, Paul Borbas MD, Eugene T. Ek MBBS, PhD, Dominik C. Meyer MD, Christian Gerber MD, FRCS

If revision of a failed anatomic hemiarthroplasty or total shoulder arthroplasty is uncertain to preserve or restore satisfactory rotator cuff function, conversion to a reverse total shoulder arthroplasty has become the preferred treatment, at least for elderly patients. However, revision of a well-fixed humeral stem has the potential risk of loss of humeral bone stock, nerve injury, periprosthetic fracture, and malunion or nonunion of a humeral osteotomy with later humeral component loosening.

Rotator Cuff Fatty Infiltration and Atrophy Are Associated With Functional Outcomes in Anatomic Shoulder Arthroplasty

Peter L. C. Lapner MD, Liangfu Jiang MD, Tinghua Zhang MSc, George S. Athwal MD

Shoulder arthroplasty provides reliable pain relief and restoration of function. However, the effects of fatty infiltration and atrophy in the supraspinatus and infraspinatus muscles on functional outcomes are not well understood.

Psychological Distress Negatively Affects Self-assessment of Shoulder Function in Patients With Rotator Cuff Tears

Michael Q. Potter MD, James D. Wylie MD, Patrick E. Greis MD, Robert T. Burks MD, Robert Z. Tashjian MD

In many areas of orthopaedics, patients with greater levels of psychological distress report inferior self-assessments of pain and function. This effect can lead to lower-than-expected baseline scores on common patient-reported outcome scales, even those not traditionally considered to have a psychological component.

High Incidence of Hemiarthroplasty for Shoulder Osteoarthritis Among Recently Graduated Orthopaedic Surgeons

Tobias Mann MD, MSc, Judith F. Baumhauer MD, MPH, Regis J. O’Keefe MD, PhD, John Harrast PhD, Shepard R. Hurwitz MD, Ilya Voloshin MD

Primary glenohumeral osteoarthritis is a common indication for shoulder arthroplasty. Historically, both total shoulder arthroplasty (TSA) and hemi-shoulder arthroplasty (HSA) have been used to treat primary glenohumeral osteoarthritis. The choice between procedures is a topic of debate, with HSA proponents arguing that it is less invasive, faster, less expensive, and technically less demanding, with quality of life outcomes equivalent to those of TSA. More recent evidence suggests TSA is superior in terms of pain relief, function, ROM, strength, and patient satisfaction. We therefore investigated the practice of recently graduated orthopaedic surgeons pertaining to the surgical treatment of this disease.

Time-dependent Changes After Latissimus Dorsi Transfer: Tenodesis or Tendon Transfer?

Ali Erşen MD, Hakan Ozben MD, Mehmet Demirhan MD, Ata Can Atalar MD, Mehmet Kapıcıoğlu MD

Transfer of the latissimus dorsi tendon to the posterosuperior part of the rotator cuff is an option in active patients with massive rotator cuff tears to restore shoulder elevation and external rotation. However, it is unknown whether this treatment prevents progression of cuff tear arthropathy.

No Difference in Postoperative Pain After Arthroscopic versus Open Rotator Cuff Repair

Gerald Williams MD, Matthew J. Kraeutler BS, Benjamin Zmistowski BS, John M. Fenlin MD

Rotator cuff repair is a successful treatment in terms of patient satisfaction and pain relief regardless of the repair method. Although arthroscopic repair is commonly thought to be less painful than open or miniopen repair, studies disagree on this point.

Patient and Procedure-specific Risk Factors for Deep Infection After Primary Shoulder Arthroplasty

Jason Richards MD, Maria C. S. Inacio PhD, Michael Beckett MD, Ronald A. Navarro MD, Anshuman Singh MD, Mark T. Dillon MD, Jeff F. Sodl MD, Edward H. Yian MD

Deep infection after shoulder arthroplasty is a diagnostic and therapeutic challenge. The current literature on this topic is from single institutions or Medicare samples, lacking generalizability to the larger shoulder arthroplasty population.

Arthroscopic Bristow-Latarjet Combined With Bankart Repair Restores Shoulder Stability in Patients With Glenoid Bone Loss

Pascal Boileau MD, Charles-Édouard Thélu MD, Numa Mercier MD, Xavier Ohl MD, Robert Houghton-Clemmey FRCS, Michel Carles MD, PhD, Christophe Trojani MD, PhD

Arthroscopic Bankart repair alone cannot restore shoulder stability in patients with glenoid bone loss involving more than 20% of the glenoid surface. Coracoid transposition to prevent recurrent shoulder dislocation according to Bristow-Latarjet is an efficient but controversial procedure.

High-energy Versus Low-energy Extracorporeal Shock Wave Therapy for Calcifying Tendinitis of the Shoulder: Which is Superior? A Meta-analysis

F. U. Verstraelen MD, N. J. H. M. Kleef MD, L. Jansen PhD, J. W. Morrenhof PhD, MD

There are several treatment options for calcifying tendinitis of the shoulder. The next step treatment after conservative treatment fails is still a matter of dispute. Extracorporeal shock wave therapy (ESWT) has been shown to be a good alternative to surgery, but the best treatment intensity remains unknown. High-energy ESWT is much more painful, more expensive, and usually is done in an inpatient setting, whereas low-energy ESWT can be performed in an outpatient setting by a physical therapist.

Hospital Readmissions After Surgical Treatment of Proximal Humerus Fractures: Is Arthroplasty Safer Than Open Reduction Internal Fixation?

Alan L. Zhang MD, William W. Schairer MD, Brian T. Feeley MD

With technologic advances such as locked periarticular plating, hemiarthroplasty of the humeral head, and more recently reverse total shoulder replacement, surgical treatment of proximal humerus fractures has become more commonplace. However, there is insufficient information regarding patient outcomes after surgery, such as the frequency of unplanned hospital readmissions and factors contributing to readmission.
