The Effect of Granulocyte-colony Stimulating Factor on Rotator Cuff Healing After Injury and Repair

David Ross MD, Tristan Maerz MS, Michael Kurdziel MS, Joel Hein MD, Shashin Doshi MD, Asheesh Bedi MD, Kyle Anderson MD, Kevin Baker PhD

The failure rate of tendon-bone healing after repair of rotator cuff tears remains high. A variety of biologic- and cell-based therapies aimed at improving rotator cuff healing have been investigated, and stem cell-based techniques have become increasingly more common. However, most studies have focused on the implantation of exogenous cells, which introduces higher risk and cost. We aimed to improve rotator cuff healing by inducing endogenous stem cell mobilization with systemic administration of granulocyte-colony stimulating factor (G-CSF).

What Are Risk Factors for 30-day Morbidity and Transfusion in Total Shoulder Arthroplasty? A Review of 1922 Cases

Chris A. Anthony MD, Robert W. Westermann MD, Yubo Gao PhD, Andrew J. Pugely MD, Brian R. Wolf MD, MS, Carolyn M. Hettrich MD, MPH

Total shoulder arthroplasty (TSA) is an effective treatment for end-stage glenohumeral joint pathology with good long-term results. Previous descriptions of morbidity and blood transfusion in TSA are limited by preoperative risk factors and postoperative complications considered and single-center studies.

Can the Ream and Run Procedure Improve Glenohumeral Relationships and Function for Shoulders With the Arthritic Triad?

Frederick A. Matsen MD, Winston J. Warme MD, Sarah E. Jackins PT

The arthritic triad of glenoid biconcavity, glenoid retroversion, and posterior displacement of the humeral head on the glenoid is associated with an increased risk of failure of total shoulder joint replacement. Although a number of glenohumeral arthroplasty techniques are being used to manage this complex pathology, problems with glenoid component failure remain. In that the ream and run procedure manages arthritic pathoanatomy without a glenoid component, we sought evidence that this procedure can be effective in improving the centering of the humeral head contact on the glenoid and in improving the comfort and function of shoulders with the arthritic triad without the risk of glenoid component failure.

Preoperative Deltoid Size and Fatty Infiltration of the Deltoid and Rotator Cuff Correlate to Outcomes After Reverse Total Shoulder Arthroplasty

Brett P. Wiater MD, Denise M. Koueiter MS, Tristan Maerz MS, James E. Moravek MD, Samuel Yonan DO, David R. Marcantonio MD, J. Michael Wiater MD

Reverse total shoulder arthroplasty (RTSA) allows the deltoid to substitute for the nonfunctioning rotator cuff. To date, it is unknown whether preoperative deltoid and rotator cuff parameters correlate with clinical outcomes.

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.
