Subacromial bursa

Shoulder injury related to vaccine administration (SIRVA) is a prolonged episode of shoulder dysfunction that commences within 24 to 48 hours of a vaccination. Symptoms include a combination of shoulder pain, stiffness, and weakness. There has been a recent rapid increase in reported cases of SIRVA within the literature, particularly in adults, and is likely related to the mass vaccination programmes associated with COVID-19 and influenza. The pathophysiology is not certain, but placement of the vaccination in the subdeltoid bursa or other pericapsular tissue has been suggested to result in an inflammatory capsular process...

Teaching Point: Leakage of fluid or intra-articular contrast from the subacromial bursa through the acromioclavicular joint, also known as the 'geyser sign', is an uncommon presentation of chronic rotator cuff injury and acromioclavicular joint degeneration.

UNLABELLED: Rotator cuff injuries result in over 500,000 surgeries performed annually, an alarmingly high number of which fail. These procedures typically involve repair of the injured tendon and removal of the subacromial bursa. However, recent identification of a resident population of mesenchymal stem cells and inflammatory responsiveness of the bursa to tendinopathy indicate an unexplored biological role of the bursa in the context of rotator cuff disease. Therefore, we aimed to understand the clinical relevance of bursa-tendon crosstalk, characterize the biologic role of the bursa within the shoulder, and test the therapeutic potential for targeting the bursa...

A 68-year-old male patient came to the orthopedics department because of swelling and pain in his left shoulder joint. He received more than 15 intraarticular steroid injections in the shoulder joint at a local private hospital. MRI showed that the synovial membrane of the joint capsule was thickened and swollen, and there were extensive "rice body-like" low T2 signal shadows filling. Arthroscopic removal of rice bodies and subtotal bursectomy were performed. The observation channel was placed through the posterior approach, and a large amount of rice bodies in yellow bursa fluid were observed to flow out...

PURPOSE: To quantify cellular senescence in supraspinatus tendon and subacromial bursa of humans with rotator cuff tears and to investigate the in vitro efficacy of the senolytic dasatinib+quercetin (D+Q) to eliminate senescent cells and alter tenogenic differentiation. METHODS: Tissue was harvested from 41 patients (mean age 62 years) undergoing arthroscopic rotator cuff repairs. In part 1 (n=35), senescence was quantified utilizing immunohistochemistry and gene expression for senescent cell markers (p16 & p21) and the senescence-associated secretory phenotype (SASP) (interleukin [IL]-6, IL-8, matrix metalloproteinase [MMP]-3, monocyte chemoattractant protein [MCP]-1)...

OBJECTIVE: To compare the effectiveness of intra-bursal injection of single-dose platelet-rich plasma (PRP) against corticosteroids under ultrasonography guidance in shoulder impingement syndrome (SIS). MATERIALS AND METHODS: This single-blind randomized controlled trial was conducted on 60 participants with a clinical diagnosis of SIS from a selected orthopedic clinic. Thirty participants in each arm were given a single dose of either PRP or triamcinolone acetonide into the subacromial sub-deltoid bursa (SASD) under ultrasonography guidance...

BACKGROUND: Individuals with paraplegia and coexisting trunk and postural control deficits rely on their upper extremities for function, which increases the risk of shoulder pain. A multifactorial etiology of shoulder pain includes "impingement" of the supraspinatus, infraspinatus, long head of the biceps tendons, and/or subacromial bursa resulting from anatomic abnormalities, intratendinous degeneration, and altered scapulothoracic kinematics and muscle activation. Targeting serratus anterior (SA) and lower trapezius (LT) activation during exercise, as part of a comprehensive plan, minimizes impingement risk by maintaining optimal shoulder alignment and kinematics during functional activities...

OBJECTIVE: To compare the diagnostic performance of standard MRI and standard MRI + ZTE images for the detection of rotator cuff calcific tendinopathy (RCCT) and to describe the artifacts encountered with ZTE images, using computed radiography (CR) as a reference. METHODS: In a retrospective study, patients with suspicion of rotator cuff tendinopathy who underwent standard MRI + ZTE images after radiography were enrolled between June 2021 and June 2022...

INTRODUCTION: The aim of this study is to compare the preservation of bursal tissue and microfracture techniques and to examine the effectiveness of the combination of the two methods in rotator cuff tear healing in the rat shoulder. HYPOTHESIS: Bursal tissue preservation combined with microfracture is more effective in the rotator cuff repair. MATERIALS AND METHODS: Twenty-three Male Sprague-Dawley rats were randomly divided into two groups...

INTRODUCTION: Intramuscular administration of vaccines into the deltoid muscle is the recommended route for most vaccines in adults. Ectopic injection into the subdeltoid/subacromial bursa can produce an inflammatory bursitis that is associated with significant long-term morbidity. CASE REPORT: We describe a novel approach to treatment of this condition: ultrasound-guided administration of dexamethasone by the emergency physician within six hours of vaccine administration...

The pathogenesis of subacromial impingement syndrome is controversially discussed. Assuming that bursal sided partial tears of the supraspinatus tendons are rather the result of a direct subacromial impact, the question arises whether there is a morphological risk configuration of the acromion and its spatial relation to the glenoid. Patients who underwent arthroscopic repair of either a partial articular supraspinatus tendon avulsion (PASTA) or bursal-sided supraspinatus tear (BURSA) were retrospectively allocated to two groups...

In this randomized controlled study, we aimed to assess the effects of US-guided injections of the subacromial bursa followed by a personalized rehabilitation program for breast cancer (BC) survivors. We assessed patients with subacromial pain syndrome without tendon lesions and with a history of post-surgical non-metastatic BC. Thirty-seven patients were enrolled and randomly assigned 1:1 to receive US-guided corticosteroid injections combined with a personalized rehabilitation program (Group A; n: 19) or US-guided corticosteroid injections alone (Group B; n: 18)...

BACKGROUND: The authors aimed to compare the effects of a one-time ultrasound (US)-guided subacromial corticosteroid injection and three-time ozone (O2 -O3 ) injection in patients with chronic supraspinatus tendinopathy. METHODS: Participants were randomly assigned to the corticosteroid group (n = 22) or ozone group (n = 22). Injections in both groups were administered into subacromial bursa with an US-guided in-plane posterolateral approach. Primary outcome measure was the change in the Western Ontario Rotator Cuff Index (WORC) score between baseline and 12-weeks post-injection...

PURPOSE: To compare the effects of anatomical preservation (AP) and interpositional preservation (IP) of subacromial bursa tissue on tendon-to-bone healing in a rat model of rotator cuff tear. METHODS: In this study, 48 male Sprague-Dawley rats (average weight 283 g) underwent bilateral supraspinatus tendons severed by sharp incision and repaired immediately. The subacromial bursa tissues were completely removed in 16 rats, who served as the control (CON) group...

This study aimed to evaluate the reliability, overall quality, and educational value of online videos for learning the techniques related to shoulder injection treatments and analyzing the usability of video evaluation tools for musculoskeletal injections. Online video searches were performed in February 2022 using the terms "shoulder injection", "glenohumeral joint injection", "acromioclavicular joint injection", and "subacromial bursa injection." Included videos were scored by modified DISCERN (mDISCERN), global quality score (GQS), and shoulder injection score (SIS)...

Background A glenohumeral (GH) joint disease, such as adhesive capsulitis, causes the shoulder capsule's fibrosis and adhesion to restrict mobility. Collagen and growth factors can be produced by platelet-rich plasma (PRP), which promotes stem cells and, as a result, improves the healing process. This study was done to determine the role of PRP injection in the treatment of adhesive capsulitis in terms of improvement in pain. Methodology This prospective cohort study was conducted at the Department of Orthopedics, Mayo Hospital, Lahore, Pakistan, from February 2022 to July 2022...

CME-Sonography 106: Subacromial Bursa - A Myth Abstract. In everyday clinical practice, we frequently encounter bursitis. It can occur in practically any joint region, for example in local mechanical overload situations, after a trauma or in the context of an inflammatory systemic disease. In this review we focus on the location of bursitis in the shoulder region and would like to contribute to get away from the "myth" called subacromial bursitis.

Background: To investigate the clinical value of ultrasound (US)-guided intervention for frozen shoulder (FS) in the frozen stage. Methods: This study included 40 patients who had primary FS in the frozen stage and were evaluated by US. These 40 patients have all received conservative treatment elsewhere, and no satisfactory results have been achieved, with no improvement in active and passive movement angles, and no improvement in scores within 3 months. Therefore, their previous treatment was set as comparison...

INTRODUCTION: The subacromial/subdeltoid bursa can develop inflammation and effusion related to autoimmune, infectious, and musculoskeletal disorders. Rice bodies, or loose bodies within bursa, have been described as an uncommon complication of bursitis and have been the subject of case studies over a number of years. However, they have not been described in anatomical or physical therapy-related literature. METHODS: A donor body dissected for a physical therapy anatomy course was found to have an enlarged subacromial/subdeltoid bursa...
