Scapular Bracing is Effective in Some Patients but Symptoms Persist in Many Despite Bracing

Martti Vastamäki MD, PhD, Veera Pikkarainen MD, Heidi Vastamäki MD, Leena Ristolainen PT, DSc

A scapular-protecting brace is one option for treating patients with a winging scapula in isolated serratus palsy. However, outcomes after brace treatment have been reported in only a few studies, and to our knowledge, none has results reported at long-term beyond 10 years.

Does Rotator Cuff Repair Improve Psychologic Status and Quality of Life in Patients With Rotator Cuff Tear?

Chul-Hyun Cho MD, PhD, Kwang-Soon Song MD, Ilseon Hwang MD, Jon J. P. Warner MD

Recently, psychological status, patient-centered outcomes, and health-related quality of life (HRQoL) in patients with scheduled or who underwent orthopaedic surgeries have been emphasized. The relationship between preoperative psychological status and postoperative clinical outcome in patients with rotator cuff repair has not yet been investigated.

Future Patient Demand for Shoulder Arthroplasty by Younger Patients: National Projections

Eric M. Padegimas MD, Mitchell Maltenfort PhD, Mark D. Lazarus MD, Matthew L. Ramsey MD, Gerald R. Williams MD, Surena Namdari MD, MSc

The outcomes of shoulder arthroplasties in younger patients (55 years or younger) are not as reliable compared with those of the general population. Greater risk of revision and higher complication rates in younger patients present direct costs to the healthcare system and indirect costs to the patient in terms of quality of life. Previous studies have suggested an increased demand for shoulder arthroplasties overall, but to our knowledge, the demand in younger patients has not been explored.

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.
