Acromial and scapular fractures after reverse shoulder arthroplasty: comparison of 3018 reverse total shoulders by inlay and onlay humeral component design.

Background: Periscapular fractures, specifically acromial and scapular spine fractures, have been identified as one of the leading complications of reverse total shoulder arthroplasty (rTSA). However, very little is known of the etiology of these postoperative fractures, or how variations in humeral designs correlates with the risk of postoperative fracture development. Therefore, the purpose of this study was to analyze the prevalence, timing, and relationship of humeral component design to acromial or scapular spine fractures.

Internal Rotation Measurements: Correlation between Vertebral Body Level and Goniometer Measurements on Functional Outcome Scores.

Objectives: Reverse total shoulder arthroplasty (rTSA) has shown success in the treatment of end-stage glenohumeral pathology. However, one major shortcoming has been the lack of internal rotation (IR), which can have significant functional consequences. Much research has been conducted to maximize IR after rTSA, but the literature is unclear which measurement of IR represents the "gold standard" between vertebral level and goniometer-based measurements.

Outpatient versus inpatient shoulder arthroplasty outcomes using an updated patient-selection algorithm: minimum 2-year follow-up.

Background: Previous studies have demonstrated the safety and cost-effectiveness of outpatient total shoulder arthroplasty (TSA), with the majority of studies focusing on 90-day outcomes and complications. Patient selection algorithms have helped appropriately choose patients for an outpatient TSA setting. This study aimed to determine the outcomes of TSA between outpatient and inpatient cohorts with at least a 2-year follow-up.

Patients undergoing reverse total shoulder arthroplasty have less pain and require fewer opioid pain medications compared to anatomic total shoulder arthroplasty in the early postoperative period: a retrospective review.

Background: Recovery after anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) has many similarities; however, recently surgeons have suggested patients undergoing rTSA have a less difficult postoperative course with less pain compared with aTSA patients. Given the heightened awareness to postoperative pain control and opioid consumption, as well as the expanding indications for rTSA, we sought to determine the differences in pain and opioid consumption between aTSA and rTSA patients in a 12-week postoperative period.

Methods: A retrospective chart review was performed to identify all patients who underwent a primary aTSA or rTSA from January 2013 to April 2018 at a single institution.

A Systematic Review of Patient Selection Criteria for Outpatient Total Shoulder Arthroplasty.

The utilization of total shoulder arthroplasty (TSA) is increasing, driving associated annual health care costs higher. Opting for outpatient over inpatient TSA may provide a solution by reducing costs. However, there is no single set of accepted patient selection criteria for outpatient TSA.

Diagnostic Evaluation of Prosthetic Joint Infections of the Shoulder: What Does the Literature Say?

The total number of patients with a total shoulder arthroplasty (TSA) is increasing, and the number of patients experiencing a (TSA) prosthetic joint infection (PJI) also will increase. It is important that physicians know how to identify signs of infection, know the common pathogens, and know how to work up a shoulder PJI. This publication reviewed the current literature about presenting signs and symptoms, common shoulder pathogens and how they differ from total knee and hip pathogens, and what images, tests, and procedures can aid in identification of infection.

Grit Score is Predictive of Increased Risk for Opioid Prescription Refill Following Primary Arthroscopic Rotator Cuff Repair.

The grit score is used to measure passion and perseverance for long-term goals. We hypothesized that higher grit scores would predict improved 90-day outcomes and reduced opioid requirements after primary arthroscopic rotator cuff repair (RCR). Included were 103 patients.

Muscle activation patterns during active external rotation after reverse total shoulder arthroplasty: an electrophysiological study of the teres minor and associated musculature.

Background: Preoperative teres minor insufficiency has been identified as a risk factor for poor restoration of external rotation (ER) after reverse total shoulder arthroplasty (RTSA). However, there has been little investigation regarding muscle activation patterns generating ER. This prospective study sought to determine the timing and activation levels of the shoulder girdle musculature during ER in well-functioning RTSAs with an intact teres minor using a lateralized design.

Superior humeral head osteophytes are associated with rotator cuff insufficiency in glenohumeral osteoarthritis: a retrospective analysis.

Purpose: The primary goal of this study was to investigate whether superior humeral head osteophyte (SHO) size is associated with rotator cuff insufficiency, including rotator cuff tear (RCT), supraspinatus tendon thickness, and fatty infiltration of the rotator cuff muscles.

Methods: Patients  ≥ 18 years who were diagnosed with glenohumeral osteoarthritis were retrospectively reviewed. SHO size was determined by radiograph.

Patient-selection algorithm for outpatient shoulder arthroplasty in ambulatory surgery center: a retrospective update.

Background: Outpatient total shoulder arthroplasty (TSA) presents a safe alternative to inpatient arthroplasty, while helping meet the rapidly rising volume of shoulder arthroplasty needs and minimizing health care costs. Identifying the correct patient for outpatient surgery is critical to maintaining the safety standards with TSA. This study sought to update an ambulatory surgery center (ASC) TSA patient-selection algorithm previously published by our institution.

Comparison of triamcinolone and methylprednisolone efficacy and steroid flare reaction rates after shoulder corticosteroid injection: a prospective interrupted time series study.

Background: A corticosteroid flare reaction is a well-described phenomenon that causes significant pain and dysfunction. The paucity of literature impedes decision making regarding which corticosteroid to use for shoulder injection. The purpose of this study was to compare methylprednisolone acetate (MPA) and triamcinolone acetonide (TA) injections in the glenohumeral joint and/or subacromial space in terms of efficacy and the incidence of steroid flare reactions.

Postoperative Rehabilitation After Shoulder Arthroplasty.

Total shoulder arthroplasty (TSA), including anatomic TSA (aTSA) and reverse TSA (rTSA), has increased in popularity due to reliably good patient outcomes. Postoperative physical therapy (PT) is considered essential to the success of this operation and has become standard practice. The authors present general rehabilitation principles as well as preferred postoperative PT protocols for aTSA and rTSA, which are based on evidence-based literature and the different early postoperative concerns for each of these procedures.

Emerging Technologies in Shoulder Arthroplasty: Navigation, Mixed Reality, and Preoperative Planning.

Shoulder arthroplasty is a rapidly improving and utilized management for end-stage arthritis that is associated with improved functional outcomes, pain relief, and long-term implant survival. Accurate placement of the glenoid and humeral components is critical for improved outcomes. Traditionally, preoperative planning was limited to radiographs and 2-dimensional computed tomography (CT); however, 3-dimensional CT is becoming more commonly utilized and necessary to understand complex glenoid and humeral deformities.

Reliability Testing of the Mayo Elbow Performance Score in Post-operative Patients.

This study aimed to determine intra-observer and inter-observer reliability of the Mayo Elbow Performance Score (MEPS). Patients undergoing elbow surgery completed a MEPS questionnaire initially and another 2-3 weeks later. During the second interview, patients completed the Oxford Elbow Score (OES) for comparison.

Acute, Traumatic Rotator Cuff Tears Have Smaller Critical Shoulder Angles Than Degenerative Tears.

Purpose: To determine whether the critical shoulder angle (CSA) in acute, traumatic rotator cuff tears (RCTs) is consistent with the previously described CSA in chronic degenerative RCTs.

Methods: We performed a multicenter retrospective analysis of 134 patients presenting to 5 surgeons fellowship trained in shoulder and elbow or sports. Preoperative imaging was used to measure the CSA and tear characteristics.

The Incidence of Posterolateral Tibial Plateau and Central Lateral Femoral Condylar Impaction Fractures in a Pediatric and Young Adult Population.

Background: Posterolateral tibial plateau and central lateral femoral condylar impaction fractures are known to occur in the setting of anterior cruciate ligament (ACL) tears. There have been no prior investigations into the incidence and morphology of posterolateral tibial plateau impaction fractures in the setting of ACL injury in a pediatric population.

Methods: Patients between 9 and 22 years of age with knee magnetic resonance imagings (MRIs) performed demonstrating complete or partial ACL tear were included in this study.

Skeletally Immature Patients With Classic Anterior Cruciate Ligament Bone Bruise Patterns Have a Higher Likelihood of Having an Intact Anterior Cruciate Ligament Compared With Skeletally Mature Patients.

Background: The incidence of anterior cruciate ligament (ACL) tears in skeletally immature patients with an ACL bone contusion pattern has been sparsely investigated. The purpose of this study is to investigate whether physeal status has an influence on the likelihood of sustaining an ACL tear when classic bipolar ACL bone bruising pattern is present.

Methods: Magnetic resonance imaging reports were queried for "contusion" on all patients between 6 and 22 years between 2015 and 2019.

Delay in Knee MRI Scan Completion Since Implementation of the Affordable Care Act:: A Retrospective Cohort Study.

Introduction: The most impactful resolutions of the Patient Protection and Affordable Care Act (ACA) took effect on January 1, 2014. The clinical and economic effects are widely experienced by orthopaedic surgeons, but are not well quantified. We proposed to evaluate the effect of the ACA on the timing of MRI for knee pathology before and after implementation of the legislation.

Frozen Shoulder Manipulation with the FEAR Technique: A Retrospective Case Series with Minimum Two-Year Follow-up.

Conservative treatment of adhesive capsulitis fails in up to 30% of patients. Manipulation under anesthesia (MUA) has been shown to be safe and effective, although complications (iatrogenic fracture, glenohumeral dislocation, rotator cuff tears, nerve injuries) have been reported. This study details a novel technique, FEAR (Forward elevation, Extension, Adduction/abduction, and internal and external Rotation), and its results.

Opioid-sparing pain management protocol after shoulder arthroplasty results in less opioid consumption and higher satisfaction: a prospective, randomized controlled trial.

Background: The opioid epidemic has become a central focus in health care. In an effort to reduce opioid use, orthopedic surgeons use multimodal strategies to control postoperative pain. However, no clear consensus exists on ideal pain management strategies after shoulder arthroplasty, and most protocols are opioid-driven.

Remplissage for Anterior Shoulder Instability: History, Indications, and Outcomes.

Remplissage is a nonanatomic capsulotenodesis of the infraspinatus tendon used to fill engaging or "off-track" Hill-Sachs lesions in patients at high risk of recurrent instability with isolated Bankart repair. Indications for remplissage are expanding, as the importance of subcritical bone loss and the glenoid track on patient outcomes and recurrence rates continues to be investigated. Remplissage is also suggested in patients at high risk of recurrent instability following isolated anterior labral repair, such as collision and contact athletes with Hill-Sachs lesions that have not reached the threshold of "off track.

Safety and short-term outcomes of anatomic vs. reverse total shoulder arthroplasty in an ambulatory surgery center.

Background: A scarcity of literature exists comparing outcomes of outpatient anatomic (aTSA) and reverse total shoulder arthroplasty (rTSA). This study was performed to compare early outcomes between the 2 procedures in a freestanding ambulatory surgery center (ASC) and to determine if the addition of preoperative interscalene nerve block (ISNB) with periarticular liposomal bupivacaine injection (PAI) in the postanesthesia care unit (PACU) would improve outcomes over PAI alone.

Methods: Medical charts of all patients undergoing outpatient primary aTSA or rTSA at 2 ASCs from 2012 to 2020 were reviewed.

Effect of deltoid volume on range of motion and patient-reported outcomes following reverse total shoulder arthroplasty in rotator cuff-intact and rotator cuff-deficient conditions.

Background: Deltoid muscle function is paramount to the success of reverse total shoulder arthroplasty. The purpose of this study was to investigate the role of deltoid volume on shoulder range of motion and patient-reported outcomes following reverse total shoulder arthroplasty in rotator cuff-intact and rotator cuff-deficient conditions.

Methods: Retrospective review of records identified 107 patients who met inclusion criteria.

Tension Hydrothorax After Attempted Arthroscopic Fixation of Greater Tuberosity Fracture in a Trauma Patient: A Case Report.

Case: We report the case of a 27-year-old man who presented after a 30-foot fall with a hemopneumothorax, multiple rib fractures, and left shoulder dislocation with greater tuberosity fracture. During attempted arthroscopic repair, the patient developed pulseless electrical activity arrest as the result of intraoperative tension hydrothorax. We hypothesize that this was caused by a traumatic soft-tissue communication to his shoulder joint from the apex of his lung.
