Delayed elective total shoulder arthroplasty: causes and eventual outcomes.

Purpose: The purpose of this study is to identify risk factors for delays in planned total shoulder arthroplasty (TSA) and determine the perioperative outcomes of TSAs that experienced a delay.

Methods: The American College of Surgeons National Quality Improvement Program (NSQIP) database was queried from 2006 to 2019 for primary TSA. Delayed TSA was defined as surgery that occurred greater than one day after hospital admission.

Perioperative complications and outcomes in patients with paraplegia undergoing rotator cuff repair.

Background: Patients with paraplegia often experience chronic shoulder pain due to overuse. We sought to determine if these patients have an increased prevalence of perioperative complications and higher rates of re-admissions and rotator cuff re-tears relative to able-bodied controls following rotator cuff repair (RCR).

Methods: We queried the NRD (2011-2018) to identify all patients undergoing primary RCR (n = 34,451) and identified cohorts of matched paraplegic and non-paraplegic patients (n = 194 each).

Comparison of Reverse and Anatomic Total Shoulder Arthroplasty in Patients With an Intact Rotator Cuff and No Previous Surgery.

Introduction: This study's purpose is to compare clinical and radiographic outcomes of primary anatomic total shoulder arthroplasty (aTSA) and primary reverse total shoulder arthroplasty (rTSA) patients with osteoarthritis (OA) and an intact rotator cuff with no previous history of shoulder surgery using a single platform TSA system at a minimum follow-up of 2 years.

Methods: A total of 370 aTSA patients and 370 rTSA patients matched for age, sex, and length of follow-up from an international multi-institutional Western Institutional Review Board approved registry with a minimum 2-year follow-up were reviewed for this study. All patients had a diagnosis of OA, an intact rotator cuff, and no previous shoulder surgery.

Clinical and radiographic outcomes following reverse total shoulder arthroplasty in patients 60 years of age and younger.

Background: Although initially indicated for use in older patients, reverse total shoulder arthroplasty (rTSA) is being increasingly used in younger patients. The purpose of this study is to compare the clinical and radiographic outcomes of patients aged <60 years to those aged 60-79 years following primary rTSA.

Methods: 154 patients aged <60 years and 1763 patients aged 60-79 years were identified from an international multi-institutional Western Institutional Review Board-approved registry with a minimum 2 years' follow-up.

Clinical and radiographic outcomes after reverse total shoulder arthroplasty in patients 80 years of age and older.

Background: Previous studies have found less favorable outcomes for patients aged 80 years and older after primary reverse total shoulder arthroplasty (rTSA). However, they are based on small sample sizes with no control group for comparison. The purpose of this study is to compare the clinical, functional, and radiographic outcomes after primary rTSA in patients aged 80 years and older with a younger cohort of patients aged 60-79 years.
