Short Stay After Shoulder Arthroplasty Does Not Increase 90-Day Readmissions in Medicare Patients Compared to Privately-Insured Patients.

J Shoulder Elbow Surg 2021 Jun 9. Epub 2021 Jun 9.

Department of Orthopaedic Surgery, Duke University Medical Center, Durham, NC 27710, USA.

Background: As of January 1, 2021 total shoulder arthroplasty was removed from the Medicare inpatient-only list, reflecting a growing belief in the potential merits of same-day discharge regardless of insurance type. It is yet unknown whether Medicare populations, who frequently have more severe comorbidity burdens, would experience higher complication rates relative to privately-insured patients who are often younger with fewer comorbidities. Given the limited number of true outpatient cohorts available to study, discharge at least by postoperative day 1 may serve as a useful proxy for true same-day discharge, and we hypothesized that these Medicare patients would have increased 90-day readmission rates compared to their privately-insured counterparts.

Changes in Scapular Bone Density Vary by Region and are Associated with Age and Sex.

J Shoulder Elbow Surg 2021 Jun 9. Epub 2021 Jun 9.

Department of Orthopaedics and Sports Medicine, University of Washington, Seattle WA, USA.

Background: Decreases in bone density of the scapula due to age and disease can make orthopedic procedures such as arthroplasty and fracture fixation challenging. There is limited information in the literature regarding the effect of age and sex on the patterns of these density changes across the bone. Characterizing these changes could assist the surgeon in planning optimal instrumentation placement. Read More

Anesthesia or analgesia? New block for shoulder surgery: pericapsular nerve group block.

Braz J Anesthesiol 2021 Jun 9. Epub 2021 Jun 9.

Kocaeli Derince Training and Research Hospital, Anesthesiology Department, Kocaeli, Turkey. Electronic address:

Interscalene brachial plexus (ISB) block is considered the analgesic technique of choice for shoulder surgery. However, the hemidiaphragmatic paresis that may occur after the block has led to the search for an alternative to the ISB block. In this case report, the pericapsular nerve group (PENG) block was performed for both surgical anesthesia and postoperative analgesia in two patients who underwent shoulder surgery. Read More

Suprascapular nerve block is a clinically attractive alternative to interscalene nerve block during arthroscopic shoulder surgery: a meta-analysis of randomized controlled trials.

J Orthop Surg Res 2021 Jun 11;16(1):376. Epub 2021 Jun 11.

Department of Orthopedic, Beijing Tsinghua Changgung Hospital, School of Clinical Medicine, Tsinghua University, No. 168 Litang Road, Dongxiaokou Town, Changping District, Beijing, 102218, China.

Background: The interscalene brachial plexus block (ISB) is a commonly used nerve block technique for postoperative analgesia in patients undergoing shoulder arthroscopy surgery; however, it is associated with potentially serious complications. The use of suprascapular nerve block (SSNB) has been described as an alternative strategy with fewer reported side effects for shoulder arthroscopy.

PLoS Genet 2021 Jun 10;17(6):e1009577. Epub 2021 Jun 10.

Shoulder Unit, Princess Elizabeth Orthopaedic Centre, Royal Devon and Exeter Hospital, Exeter, United Kingdom.

Frozen shoulder is a painful condition that often requires surgery and affects up to 5% of individuals aged 40-60 years. Little is known about the causes of the condition, but diabetes is a strong risk factor. To begin to understand the biological mechanisms involved, we aimed to identify genetic variants associated with frozen shoulder and to use Mendelian randomization to test the causal role of diabetes.
