Greater Tuberosity Fractures: Does Fracture Assessment and Treatment Recommendation Vary Based on Imaging Modality?

Stein J. Janssen MD, Hugo H. Hermanussen BSc, Thierry G. Guitton MD, PhD, Michel P. J. Bekerom MD, Derek F. P. Deurzen MD, David Ring MD, PhD

For greater tuberosity fractures, 5-mm displacement is a commonly used threshold for recommending surgery; however, it is unclear if displacement can be assessed with this degree of precision and reliability using plain radiographs. It also is unclear if CT images provide additional information that might change decision making.

Is Arthroscopic Technique Superior to Open Reduction Internal Fixation in the Treatment of Isolated Displaced Greater Tuberosity Fractures?

Weixiong Liao PhD, Hao Zhang PhD, Zhongli Li PhD, Ji Li MD

Arthroscopic double-row suture-anchor fixation and open reduction and internal fixation (ORIF) are used to treat displaced greater tuberosity fractures, but there are few data that can help guide the surgeon in choosing between these approaches.

Open Surgical Treatment for Snapping Scapula Provides Durable Pain Relief, but so Does Nonsurgical Treatment

Martti Vastamäki MD, PhD, Heidi Vastamäki MD, PhD

Resection of the medial upper corner of the scapula is one option for treating patients with a painful chronic snapping scapula. However, the degree to which this procedure results in sustained relief of pain during long-term followup, and whether surgical treatment offers any compelling advantages over nonsurgical approaches at long-term followup, are not known.

Obesity is Not Associated with Increased Short-term Complications After Primary Total Shoulder Arthroplasty

Jimmy J. Jiang MD, Jason R. Somogyi MD, Pranay B. Patel MD, Jason L. Koh MD, Douglas R. Dirschl MD, Lewis L. Shi MD

Few studies have analyzed the association between elevated BMI and complications after total shoulder arthroplasty (TSA). Previous studies have not consistently arrived at the same conclusion regarding whether obesity is associated with a greater number of postoperative complications. We used a national surgical database to compare the 30-day complication profile and hospitalization outcomes after primary TSA among patients in different BMI categories.

No Differences in Early Results of a Hybrid Glenoid Compared With a Pegged Implant

Lawrence V. Gulotta MD, K. Lauchlan Chambers MD, Russell F. Warren MD, David M. Dines MD, Edward V. Craig MD, MPH

Glenoid component loosening after total shoulder arthroplasty is one of the most common causes of failure. A hybrid glenoid that uses peripherally cemented pegs and a central press-fit post may improve implant longevity.

Implant Design Variations in Reverse Total Shoulder Arthroplasty Influence the Required Deltoid Force and Resultant Joint Load

Joshua W. Giles PhD, G. Daniel G. Langohr MASc, James A. Johnson PhD, George S. Athwal MD

Reverse total shoulder arthroplasty (RTSA) is widely used; however, the effects of RTSA geometric parameters on joint and muscle loading, which strongly influence implant survivorship and long-term function, are not well understood. By investigating these parameters, it should be possible to objectively optimize RTSA design and implantation technique.

One-year Patient-reported Outcomes After Arthroscopic Rotator Cuff Repair Do Not Correlate With Mild to Moderate Psychological Distress

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

Patients with shoulder and rotator cuff pathology who exhibit greater levels of psychological distress report inferior preoperative self-assessments of pain and function. In several other areas of orthopaedics, higher levels of distress correlate with a higher likelihood of persistent pain and disability after recovery from surgery. To our knowledge, the relationship between psychological distress and outcomes after arthroscopic rotator cuff repair has not been similarly investigated.

Posterior Glenoid Wear in Total Shoulder Arthroplasty: Eccentric Anterior Reaming Is Superior to Posterior Augment

Tim Wang MD, Geoffrey D. Abrams MD, Anthony W. Behn MS, Derek Lindsey MS, Nicholas Giori MD, Emilie V. Cheung MD

Uncorrected glenoid retroversion during total shoulder arthroplasty may lead to an increased likelihood of glenoid prosthetic loosening. Augmented glenoid components seek to correct retroversion to address posterior glenoid bone loss, but few biomechanical studies have evaluated their performance.
