Rotator cuff impingement

OBJECTIVE: Rotator cuff (RC) tears often necessitate surgery, with acromioplasty being frequently performed alongside RC repair. However, the impact of acromioplasty on clinical outcomes remains a subject of discussion. The current study aimed to investigate the effect of acromioplasty during RC repair on clinical outcomes in patients with type 3 acromion. MATERIALS AND METHODS: Eighty-five patients, who underwent RC repair between January 2016 and December 2020, were categorized into two groups: Group 1, comprising 40 patients without acromioplasty, and Group 2, including 45 patients who received acromioplasty...

A comprehensive review of scapular pathologies and their effect on shoulder function is necessary to determine the best treatment options. The coordinated motion between the scapulothoracic and glenohumeral joints is essential for shoulder motion and depends on the balanced activity of the periscapular muscles. Disruption in these muscles can cause abnormal scapular motion and compensatory glenohumeral movements, leading to misdiagnosis or delayed diagnosis. Scapular pathologies can arise from muscle overactivity or underactivity/paralysis, resulting in a range of scapulothoracic abnormal motion (STAM)...

INTRODUCTION: Shoulder pain is one of the most frequently reported musculoskeletal conditions that approximately 6.9 to 26% of people experience. Numerous etiologies have been linked to causing shoulder pain, with the most frequent one being rotator cuff tendinopathy. Work-related musculoskeletal pain is prevalent in the medical field in general, but orthopaedic surgeons account for the majority of cases overall. The pain experienced is usually caused by many attributing factors that all relate to either the long hours and physically intensive procedures or the unnatural positions orthopaedic surgeons are put in during their surgeries...

BACKGROUND: Rotator cuff injury occurs over tendons that insert into the humeral tuberosity. Ultrasonography detects the size and extent of tendon tears. Its sensitivity and specificity range from 91-100% and 85-86%, respectively. It has been shown that a trained orthopedic surgeon can perform shoulder ultrasonography for the accurate diagnosis of rotator cuff pathology. OBJECTIVE: To determine the concordance between ultrasound-arthroscopy of the shoulder in rotator cuff injuries at the Unidad Médica Atención Ambulatoria No...

Subacromial impingement syndrome (SIS) is one of the most common causes of shoulder pain in adults and is caused by muscle imbalance around the shoulder joint, which is referred to as secondary SIS. Centralization of the glenohumeral joint (CGH), one of the intervention methods for this, targets strengthening the control ability of the rotator cuff. Dynamic humeral centering (DHC) targets the learning of selective contractile function of the pectoralis major and latissimus dorsi as depressors of the humeral head...

Exercise therapy for individuals with rotator cuff tears fails in approximately 25.0 % of cases. One reason for failure of exercise therapy may be the inability to strengthen and balance the muscle forces crossing the glenohumeral joint that act to center the humeral head on the glenoid. The objective of the current study was to compare the magnitude and orientation of the net muscle force pre- and post-exercise therapy between subjects successfully and unsuccessfully (e.g. eventually underwent surgery) treated with a 12-week individualized exercise therapy program...

BACKGROUND: The bone morphology of the greater tuberosity and lateral acromion plays a central role in subacromial impingement syndrome. The critical shoulder angle (CSA) and greater tuberosity angle (GTA) are two-dimensional measurement parameters that have been validated to evaluate it radiologically. These markers are, however, static and don't consider the dynamic effect of glenohumeral motion. OBJECTIVES: This study aimed to better understand the biomechanics in subacromial impingement with a dynamic simulation based on a validated 3D biomechanical model coupling joint kinematics and 3D reconstructed computed tomography...

Overhead throwing, particularly in baseball, subjects the shoulder and elbow to various unique injuries. Capsular contracture following repetitive external rotation shifts the humeral head posterosuperiorly, predisposing to glenohumeral internal rotation deficit (GIRD), Bennett, posterosuperior internal impingement (PSI), and superior labrum anterior-posterior (SLAP) lesions. GIRD represents loss of internal rotation at the expense of external rotation. Bennett lesion represents ossification of the posteroinferior glenohumeral ligament due to repetitive traction...

Objective  The objectives of this study are to compare absolute values of acromial index (AI) and critical shoulder angle (CSA) obtained in both radiographs and magnetic resonance image (MRI) of the shoulder; and to compare the interobserver and intra-observer agreement for AI and CSA values measured in these image modalities. Methods  Patients who had medical indication of investigating shoulders conditions through radiographs and MRI were included. Images were taken to two fellowship-trained shoulder surgeons, which conducted measurements of AI and CSA in radiographs and in MRI...

BACKGROUND: Systematic analysis of compensation claims following patient injuries is helpful in improving patient safety. The objective of the current study was to assess compensation claims after arthroscopic treatment of rotator cuff ruptures, impingement, and acromioclavicular joint osteoarthritis reported to the Norwegian System of Patient Injury Compensation and evaluate if there was regional variation on the risk of patient injuries leading to an accepted compensation claim. METHODS: Data from the Norwegian System of Patient Injury Compensation and the Norwegian Patient Registry (NPR) from 2008 to 2018 were collected...

The purpose of this study was to develop a multivariable model to determine the extent to which a combination of etiological factors is associated with supraspinatus tendon tears. Fifty-four asymptomatic individuals (55±4 years) underwent testing of their dominant shoulder. Diagnostic ultrasound was used to assess for a supraspinatus tendon tear. The etiological factors investigated included: demographics (age and sex), tendon impingement during shoulder motion (via biplane videoradiography), glenohumeral morphology (via CT imaging), family history of a tear (via self-report), occupational shoulder exposure (via shoulder job exposure matrix), and athletic exposure (via self-report)...

Subacromial impingement (SAI) is associated with shoulder pain and dysfunction, and is exacerbated by rotator cuff tears; however, the role of acromioplasty in mitigating subacromial contact in the rotator cuff deficient shoulder remains debated. This study aimed to quantify the influence of isolated and combined tears involving the supraspinatus on subacromial contact during abduction; and secondly, to evaluate the influence of acromioplasty on joint space size and subacromial contact under these pathological conditions...

BACKGROUND: The best course of action for massive irreparable rotator cuff tears (MIRCTs) is not universally agreed upon. Numerous surgical techniques have been discussed. The implantation of a biodegradable spacer into the subacromial area has been documented since 2012 by several authors. The implantation method is touted as being simpler, repeatable, and less invasive than other solutions that are now available. The purpose of this systematic review and meta-analysis, being the first of its kind, was to evaluate the literature to see the efficacy of InSpace balloon (ISB) implantation in the management of MIRCTs...

Introduction Subacromial impingement syndrome (SIS) is a common shoulder disorder characterized by pain and limited range of motion in the shoulder joint. It is frequently attributed to the compression or impingement of the rotator cuff tendons and bursa between the humeral head and the acromion process of the scapula during arm elevation. Subacromial impingement syndrome may arise as a result of the morphology of the acromion process, a bony protrusion at the top of the scapula that is important in the biomechanics of the shoulder joint...

BACKGROUND: The purpose of this study was to develop a deep learning approach to automatically segment the scapular bone on magnetic resonance imaging (MRI) images and to compare the accuracy of these three-dimensional (3D) models with that of 3D computed tomography (CT). METHODS: Fifty-five patients with high-resolution 3D fat-saturated T2 MRI were retrospectively identified. The underlying pathology included rotator cuff tendinopathy and tears, shoulder instability, and impingement...

Implantable cardioverter-defibrillators (ICDs) have demonstrated efficacy in the prevention of sudden cardiac death secondary to cardiac arrhythmias in eligible patients. Complications with the subcutaneous ICD (S-ICD) are rarer than with the transvenous ICD but do still exist. Our patient presented four weeks after the insertion of S-ICD with complaints of left shoulder pain radiating to the chest wall and swelling over the S-ICD site. He was initially treated for rotator cuff injury and subacromial impingement syndrome but upon obtaining chest radiography was found to have a lead displacement traversing the splenic flexure of the colon...

Impingement, especially subacromial impingement, is one of the most frequent causes of shoulder pain. It results in soft tissue pathologies due to constriction of the subacromial space. It can lead to tendon pathologies and bursitis. In addition to the clinical examination, imaging methods such as magnetic resonance imaging (MRI), MRI arthrography, ultrasound and X‑ray examinations are helpful in making a diagnosis or evaluating the cause of pain. Conservative treatment approaches, such as rest, medication, physiotherapy, manual therapy and infiltrations should primarily be used...

BACKGROUND: Several surgical techniques are used to treat bursal-side partial thickness rotator cuff tears (PTRCTs). However, use of single knotless-anchor with two Ethicon 2# repair technique for PTRCTs has not been reported. MATERIALS AND METHODS: Bursal-side PTRCTs (Ellman grade III, 75% thickness of tears) were created in the supraspinatus tendon in 16 fresh-frozen cadaveric shoulders. The specimens were randomly assigned to two equal groups: (1) Group A (Transtendon repair), a single knotless-anchor repair with two Ethicon 2#; (2) Group B, Conversion repair (Double-row, DR)...

BACKGROUND: Dislocation is a major complication of reverse total shoulder arthroplasty (RSA). Humeral liner may be changed to the constrained type when stability doesn't improve by increasing glenosphere size or lateralization with implants, and patients, particularly women with obesity, have risks of periprosthetic instability that may be secondary to hinge adduction on the thorax, but there are few reports on its impact on the range of motion (ROM). This study aimed to determine the influence of humeral liner constraint on impingement-free ROM and impingement type utilizing an RSA computer simulation model...

OBJECTIVE: Rotator cuff-related shoulder pain (RCRSP) is the most common form of shoulder pain. Exercise therapy is a first-line recommended treatment for RCRSP. However, the causal mechanisms underpinning the benefits of exercise for RCRSP are not well understood. Moreover, how individuals with lived experience of RCRSP believe exercise helped or did not help them is unknown. This study aimed to gain insights into how individuals with RCRSP believe exercise influenced their shoulder pain and identify the clinical conditions that promoted or inhibited their beliefs...
