Editorial Commentary: Magnetic Resonance Imaging Reveals Rotator Cuff Tear Size, Retraction, Length, and Geometry; Muscle Volume and Degeneration; and Tendon Quality.

Magnetic resonance imaging (MRI) of the shoulder is commonly used for evaluating muscle bulk and fatty degeneration, as well as tendon tear size, geometry, retraction, and length. However, MRI can also be used to evaluate tendon quality. Increased rotator cuff tendon signal on T2-weighted fat-suppressed MRI appears to be a marker of tendon degeneration and potentially of impaired healing potential.

Untwining the intertwined: a comprehensive review on differentiating pathologies of the shoulder and spine.

Background: The anatomic interplay and overlap between the cervical spine and the shoulder constitutes a challenge for shoulder and spine surgeons, as symptoms of spine and shoulder pathologies are often similar and may lead to entity misdiagnosis.

Methods: PubMed, Cochrane, and Google Scholar (page 1-20) searches were updated to October 2023 in search of the qualified papers. Boolean Operators were used with a combination of the keywords "spine" OR "neck" And "Shoulder".

Arthroscopic Removal of Loose Glenoid Component in Anatomic Total Shoulder Arthroplasty.

Aseptic glenoid component loosening after anatomic total shoulder arthroplasty remains an important cause of late clinical failure and revision surgery. We present here the surgical technique of all-arthroscopic removal and glenoid bone grafting. Arthroscopic removal of a loose glenoid component and bone grafting of the glenoid defect without dermal allograft preserves glenoid bone stock and obviates the need for multiple suture anchors to hold the graft in place.

Arthroscopic Repair of Retracted Large and Massive Rotator Cuff Tears With and Without Augmentation With a Bio-Inductive Collagen Implant Reveals Substantial and Comparable Clinical Improvement.

Purpose: To compare clinical and imaging results after repair of retracted large and massive full-thickness rotator cuff tears, including revision repairs, with and without augmentation with a bio-inductive collagen implant.

Methods: The study group comprised 24 patients (17 male subjects) with retracted 2 or 3 tendon rotator cuff tears undergoing arthroscopic repair followed by onlay augmentation with a bio-inductive collagen implant. The control group comprised 24 patients (19 male subjects) matched by tear size undergoing repair without augmentation.

Editorial Commentary: Avoiding Complications in Elbow Arthroscopy: Know the Indications, Learn the Anatomy, and Master a Safe Technique.

Elbow arthroscopy enables surgeons to treat a vast range of elbow injuries and pathologies in a minimally invasive manner. It has a lower morbidity rate and is often followed by a faster recovery than traditional open surgery unless it is followed by a serious complication. Although most complications are minor and transient, the incidence of both minor and major complications is considerably higher than that after arthroscopy of other joints, specifically the risk of neurovascular injury including permanent nerve injury because of the proximity of neurovascular structures.

Total shoulder arthroplasty in patients aged 80 years and older: a systematic review.

Background: Elderly patients and their surgeons may eschew shoulder arthroplasty due to concerns over patient safety and longevity. The purpose of this study was to review the current literature evaluating the clinical and radiographic outcomes of shoulder arthroplasty performed in patients 80 years and older.

Methods: A literature search of the Embase, PubMed, Medline, and Cochrane databases was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

Adult appendicitis score versus Alvarado score: A comparative study in the diagnosis of acute appendicitis.

Background: Acute Appendicitis (AA) is the most common abdominal surgical emergency. It requires proper management to decrease mortality and morbidity. Clinical scoring systems for diagnosing AA aimed to decrease the use of radiological scans and the rate of negative appendectomies (NA).

Editorial Commentary: Superior Capsular Reconstruction Employing Allograft Heals and Functions Well if the Graft Is Sufficiently Thick and Stiff.

Superior capsular reconstruction (SCR) has fallen into disrepute, and the numbers performed appear to be on the decline because it is technically demanding and time-consuming, requires a long postoperative recovery, and does not always heal or function as expected. In addition, two "new kids on the block," the subacromial balloon spacer and the lower trapezius tendon transfer, have emerged as viable alternatives for low-demand patients who cannot tolerate a lengthy recovery and for high-demand patients who lack external rotation strength, respectively. However, carefully selected patients continue to do well after SCR, when surgery is meticulously performed using a graft that is sufficiently thick and stiff.

Prosthetic shoulder arthroplasty in patients 40 years or younger: outcomes stratified by diagnosis and surgery.

Background: The outcomes of patients 50-55 years old or younger undergoing prosthetic shoulder arthroplasty (PSA) may not generalize to younger patients. We report outcomes following PSA in a consecutive series of patients 40 years or younger. We hypothesize that total shoulder arthroplasty (TSA) provides better outcome and durability than resurfacing hemiarthroplasty (RHA).

Due to the COVID-19 epidemic and the curfew caused by it, many people have sought to find an ADPS on the internet in the last few years. This hints to a new age of medical treatment, all the more so if the number of internet users continues to expand. As a result, automatic illness prediction online applications have attracted the interest of a large number of researchers worldwide.

Addressing Arthroscopic-Assisted Acromioclavicular Joint Reconstruction in the Beach Chair Position With Concomitant Labral Pathology in the Lateral Decubitus Position.

High-grade Acromioclavicular (AC) injuries are complete dislocations, involving ruptures of the AC and coracoclavicular ligaments. They occur following trauma after a fall, direct-blow to an adducted arm, or indirectly by falling onto an abducted, outstretched extremity. Given this traumatic etiology, additional intra-articular pathologies can arise and may go unnoticed because of the painful and prominent AC joint (ACJ).

Reverse shoulder arthroplasty in patients 85 years and older is safe, effective, and durable.

Background: Reverse shoulder arthroplasty (RSA) was originally indicated for older adults, but outcomes in the oldest patients have not been studied. The purpose of this study was to report on patients aged ≥85 years undergoing RSA. We hypothesized that RSA would be safe, effective, and durable.

Editorial Commentary: A Consensus of Experts Complements the Clinical Evidence on Diagnosis and Treatment of Anterior Glenohumeral Instability.

The current diagnostic and treatment strategies for anterior glenohumeral instability have been refined by high-quality clinical and basic science studies, but many controversies remain. These include the bone loss threshold for arthroscopic Bankart repair and the influence of other clinical factors on this decision, the optimal bracing position following anterior glenohumeral dislocation, and the optimal coracoid graft orientation during the Latarjet procedure. Randomized clinical trials often present conflicting results, and many of these are small-sample and fragile studies.

Editorial Commentary: Monitoring Tendon and Muscle Recovery After Rotator Cuff Repair Using Diagnostic Ultrasound Demonstrates that Early Repair is Beneficial for Many Patients With Reparable Tears.

Rotator cuff repair is performed to effect healing of the enthesis; to restore shoulder comfort, strength, and function; to prevent tear propagation; and to prevent progression of atrophic muscle changes (fatty degeneration, fatty infiltration, and fatty atrophy) that eventually occur. Non-retracted and moderately retracted rotator cuff tears usually heal after repair, and muscle atrophy may recover over time. It follows that early rotator cuff repair is beneficial for many patients with chronic but reparable rotator cuff tears.

Shoulder Hemiarthroplasty with Nonprosthetic Glenoid Arthroplasty: The Ream-and-Run Procedure.

»: Glenoid component wear and loosening are the principal failure modes of anatomic total shoulder arthroplasty (aTSA).

»: The ream-and-run (RnR) procedure is an alternative glenohumeral arthroplasty for patients who wish to avoid the risks and limitations of a prosthetic glenoid component.

»: During the RnR procedure, the arthritic glenoid is conservatively reamed to a single concavity, while the prosthetic humeral component and soft tissues are balanced to provide both mobility and stability of the joint.

Editorial Commentary: Superior Capsular Reconstruction Works Biomechanically but Should Be Used Selectively for Genuinely Irreparable Tears.

Superior capsular reconstruction (SCR) has undergone extensive biomechanical and clinical study. Systematic review of biomechanical studies has shown that SCR functions to depress the humeral head and improve the glenohumeral register, which provides proof of concept. Clinical studies have shown the short-term effectiveness of SCR, but this is influenced by graft type and thickness, as well as surgical technique.

Editorial Commentary: Biology and Biomechanics Must Be Carefully Balanced for a Durable Rotator Cuff Repair.

Arthroscopic rotator cuff repair strategies have evolved over 3 decades, but suture anchor design, anchor configuration, and stitches have been largely driven by repair biomechanics. In recent years there has been a shift toward repair strategies that enhance the biology of tendon repair. Double-row and transosseous equivalent suture anchor repair constructs demonstrate excellent time zero mechanical properties, but the resulting increased repair tension and tendon compression may compromise tendon healing.

Flavonoids in the Treatment of Diabetes: Clinical Outcomes and Mechanism to Ameliorate Blood Glucose Levels.

Background: For thousands of years, natural food products have been used as a medicine for treating diseases that affect the human body, including diabetes mellitus (DM). Lately, several investigations have been performed on the flavonoid derivatives of plant origin, and their biological activity has been extensively studied.

Methods: Given our need to know more mechanisms for treating DM, we performed a thorough research review on treating diabetes mellitus based on flavonoids, their therapeutic potential, and biological action.

Arthroscopic Evaluation and Treatment of Complications That Arise Following Prosthetic Shoulder Arthroplasty.

Arthroscopy may be used to diagnose symptomatic glenoid loosening following anatomic total shoulder arthroplasty (aTSA), and arthroscopic glenoid component removal may suffice as treatment for some patients. Arthroscopy may be used to diagnose shoulder prosthetic joint infection (PJI) following aTSA and reverse shoulder arthroplasty (RSA). Tissues are biopsied from multiple sites within the joint and the subdeltoid or subacromial space, and they are cultured for a minimum of 14 days.

Editorial Commentary: Classic and Congruent-Arc Latarjet Techniques Are Equally Safe and Effective Procedures, so Choose Whichever Technique Works Best in Your Hands for Your Patients.

The classic and congruent-arc Latarjet techniques are equally safe and effective in restoring glenohumeral stability, even when performed as a revision of a failed stabilization. The classic technique provides a broader contact area for healing and facilitates and improves screw fixation. The congruent-arc technique theoretically optimizes glenohumeral contact forces because of the matched radius of curvature, provides better restoration of glenoid depth, and restores larger glenoid defects.

Management of irreparable massive rotator cuff tears: a systematic review and meta-analysis of patient-reported outcomes, reoperation rates, and treatment response.

Background: There is no consensus on the treatment of irreparable massive rotator cuff tears. The goal of this systematic review and meta-analysis was to (1) compare patient-reported outcome scores, (2) define failure and reoperation rates, and (3) quantify the magnitude of patient response across treatment strategies.

Methods: The MEDLINE, Embase, CENTRAL (Cochrane Central Register of Controlled Trials), and Scopus databases were searched for studies including physical therapy and operative treatment of massive rotator cuff tears.

Defining massive rotator cuff tears: a Delphi consensus study.

Background: A standard definition for massive rotator cuff tears (MRCTs) has not been identified. The purpose of this study is to use the modified Delphi technique to determine a practical, consensus definition for MRCTs.

Methods: This study is based on responses from 20 experts who participated in 4 rounds of surveys to determine a consensus definition for MRCT.

Single-Shot Versus Continuous Interscalene Block for Postoperative Pain Control After Shoulder Arthroplasty: A Prospective Randomized Clinical Trial.

Introduction: Continuous catheter infusion of local anesthetics extends the efficacy of regional anesthesia after prosthetic shoulder surgery. Our purpose was to compare continuous interscalene block (CIB) with single-shot interscalene block, and the hypothesis was these would offer similar safety and efficacy in patients with prosthetic shoulder arthroplasty.

Methods: Seventy-six patients were randomized to ropivacaine single-shot interscalene block or CIB after prosthetic shoulder arthroplasty.
