Ultrasonographic characteristics of the shoulder in patients with shoulder pain: A retrospective study comparing younger and older age groups

Background Shoulder pain can be caused by structures within the shoulder joint or external structure to shoulder and the prevalence of shoulder pain is high. Objective The purpose was to investigate the ultrasonographic characteristics of patients with shoulder pain and to study the association between age groups (less than 60 years vs. 60 years and above) and commonly found abnormal ultrasonographic findings. Methods A retrospective study was conducted on 253 patients experiencing shoulder pain over a month. Data included gender, age, side of pain, pain duration, painful area, previous treatments, clinical assessment of shoulder pain. The abnormal findings in shoulder ultrasound images were reported, and the association between age group with common ultrasound abnormalities were analyzed using the chi-square test. Results Common abnormal ultrasound findings included subdeltoid bursitis (82.7%), biceps tendon effusion (48.7%), and supraspinatus tendinosis (44.2%). Moreover, patients aged 60 years and above had a significantly higher prevalence of biceps tendon effusion (53.6% vs 36.0%), supraspinatus tendon tear (19.3% vs 8.6%) and subscapularis tendon tear (6.1% vs 1.4%) compared to those aged less than 60 years. Conclusion The common abnormal ultrasound findings in patients with shoulder pain were subdeltoid bursitis, biceps tendon effusion and supraspinatus tendinosis. Patients aged 60 years and above had a significantly higher prevalence of biceps tendon effusion and tears in the supraspinatus and subscapularis tendons.

Musculoskeletal ultrasound of the shoulder in patients with adhesive capsulitis.

Adhesive capsulitis is a common pathological condition of the shoulder that affects the general population. The aim of the present study was to explore shoulder ultrasonographic findings in patients with adhesive capsulitis. A cross-sectional descriptive study was conducted on 96 patients with adhesive capsulitis. Abnormal shoulder ultrasonographic findings were found in all participants. The top three abnormal ultrasonographic imaging features were biceps tendon effusion (71.8%), positive dynamic supraspinatus impingement (56.2%) and subdeltoid-subacromial bursitis (47.9%). By assessing the relationship between limited functional shoulder range of motion (ROM) and abnormal shoulder ultrasonographic findings, limited passive ROM (PROM) with shoulder flexion of ≤120 degrees was found to be significantly associated with positive dynamic supraspinatus impingement. Similarly, limited PROM in shoulder abduction of ≤130 degrees was found to be significantly associated with subdeltoid and subacromial bursitis, as well as positive dynamic supraspinatus impingement. In addition, limited PROM with shoulder internal rotation of ≤60 degrees was significantly associated with positive dynamic supraspinatus impingement. Varying abnormal shoulder ultrasonographic findings were obtained in patients with adhesive capsulitis. Therefore, it should be cautioned that relying solely on physical examination may not accurately indicate true shoulder pathology and it is suggested that the final diagnosis should be based on a combination of the patients' clinical and overall ultrasonographic findings.

Musculoskeletal Pathologies Affecting Shoulder Girdle: A Systematic Review with Anatomical and Radiological Validation

Abstract Musculoskeletal pathologies affecting shoulder girdle joints, other than gleno-humeral joint such as acromioclavicular joint arthritis, tendonitis, subacromial bursitis, subdeltoid bursitis, and osteochondritis dissecans, are relatively rare. In Middle East and Asian countries, public health services are generally availed by a large number of patients in primary health centres, rural hospitals, and district hospitals, but the scarcity of specialist orthopaedic surgeons in such hospitals usually leads to misdiagnosis of rare musculoskeletal pathologies, which may result in complications and morbidity. The study aims to determine the presentation, progression, diagnostic evaluation, and treatment of musculoskeletal pathologies affecting the shoulder girdle and develop an algorithm to screen such pathologies. A systematic literature search of four medical databases (PubMed, Scopus, Web of Science and Google Scholar) was conducted, from 1st January 1950 to 31st December 2022. Studies (case reports, prospective studies, review articles) reporting pathological conditions affecting shoulder girdles, with a focus on clinical presentation, physical examination tests required for diagnostic evaluation, and management, were included. The relevant data was extracted from the selected studies and tabulated for analysis. Seventeen studies were included in the final analysis. Several case reports, case series and review articles showed that very few musculoskeletal conditions can be correctly diagnosed based on only physical examination tests. Radiological and anatomical basis of each of the cases were discussed. An algorithm was prepared to help diagnose shoulder girdle pathologies based on clinical presentation and examination findings.

Ultrasound imaging in spinal cord injury patients with shoulder pain

Objective To examine shoulder ultrasound imaging in both tetraplegic and paraplegic spinal cord injury (SCI) patients with shoulder pain. Methods All 28 individuals with SCI with shoulder pain were enrolled in this study. Fifty-six shoulders were evaluated by ultrasound (US) imaging. Results Fourteen tetraplegics and 14 paraplegics were enrolled (age 45.4 ± 13.8 years [mean ± SD]). Median time post-SCI was 8.6 years. Twenty-three individuals (82.1%) were independent in transfer and four individuals (14.3%) were partially independent in transfer. The prevalence of shoulder pain was 78.6% in manual wheelchair ambulators, 10.7% in gait aids users, 7.1% in wheelchair sitters, and 3.6% in no assistive device individuals. Abnormal US imaging was found in 24/28 (85.7%) individuals. Total shoulder US abnormalities were 38 units. Most common abnormal US imaging was supraspinatous tendinosis (42.1%), biceps tendon effusion (23.7%), positive dynamic supraspinatus impingement (21.1%), and subdeltoid bursitis (18.4%). Conclusions Shoulder ultrasonographic abnormalities were common in the patients with SCI with shoulder pain. The supraspinatus tendinosis is the most common abnormal US imaging in patients with SCI with shoulder pain.

Pattern of Radiographic and Sonographic Findings of Adult Patients Presented with Shoulder Pain at Tikur Anbessa Hospital, Addis Ababa, Ethiopia.

Shoulder pain is one of the most common presentations in the orthopedic clinic. Multiple factors have been found to cause shoulder pain. Radiographs and ultrasound are widely available, relatively cheap modalities in assessing shoulder pain. The aim of this study is to assess the radiographic and sonographic imaging patterns of shoulder pain. A descriptive prospective cross-sectional hospital-based study was conducted at the Department of Radiology of Tikur Anbessa Specialized Hospital among patients with shoulder pain that came for imaging from August 2021-January 2022. Of the 73 patients with shoulder pain included in the study, 67% were females while 33% males. The mean age was 51.7 years. Radiographs found pathology in 53% of the cases. Acromioclavicular joint osteoarthritis, greater tuberosity degenerative changes, rotator cuff calcification were common radiographic findings. Ultrasound detected pathologies in 87% of the cases. The common pathologies were rotator cuff pathologies, biceps tendon pathologies, acromioclavicular joint degeneration, greater tuberosity degenerative changes, subacromial subdeltoid bursitis, and adhesive capsulitis. There was a significant association between greater tuberocity degenerative changes and supraspinatous pathologies with age, greater tuberocity degenerative changes with supraspinatous pathologies, acromiohumeral distance of <7mm with supraspinatous pathology. Radiographs and ultrasound are valuable imaging modalities for shoulder pain. Low acromiohumeral interval, greater tuberosity degenerative changes, and acromioclavicular joint osteoarthritis are associated with rotator cuff tears. Rotator cuff pathologies are the most common pathologies observed in ultrasound. We recommend ultrasound to be second step after radiograph due to its low cost and wide availability.

Ultrasound Findings in Adult Patients with Chronic Shoulder Pain Having No History of Trauma

OBJECTIVE: To evaluate the frequency of non-traumatic chronic shoulder pain sonographically in the local population. METHODOLOGY: This cross-sectional study was conducted at the Department of Radiology, Combined Military Hospital Malir, from March to October 2020. A history of shoulder pain of more than one month duration was included. Patients with a History of shoulder dislocation, neurological, renal, hepatic and cardiac diseases were excluded. The sample size was 196. A non-probability consecutive sampling technique was employed. SPSS version 23 was used for statistical analysis. RESULTS: 196 patients (69.9% males and 30.1% females) with non-traumatic shoulder pain (56.4 % right side and 43.4% left) were scanned. The mean age was 42.80±11.20 years. Out of 196, 118(60.2%) were having complaints in dominant limbs (right 51.0% and left 9.2%); 78(39.8%) were having pain in non-dominant limbs (right 6.6% and left 33.2%). Significant findings were supraspinatus partial tear (46.9%), sub-acromial sub-deltoid bursitis(8.2%), and biceps tenosynovitis(6.1%), adhesive capsulitis, a complete tear of supraspinatus tendon, impingement syndrome, joint effusion, subscapularis tendon tear and tenosynovitis. 44(22.4%) patients had two pathologies, and 31 (15.8%) patients had three pathologies, respectively. Significant co-existent findings were biceps tenosynovitis (13.8%), Impingement syndrome (9.2%), bursitis (8.2%) and joint effusion (7.1%). Age and number of pathological were moderately positively correlated, r (194) = 0.46, p &lt; 0.01 and keeping CI = 95%. CONCLUSION: Partial tears of the supraspinatus tendon were the most common pathology in non-traumatic shoulder myalgia, diagnosed on ultrasound, followed by sub-acromial sub-deltoid bursitis and biceps tenosynovitis, having moderate linear relation with age.

Chronic shoulder injury related to vaccine administration following coronavirus disease 2019 vaccination: a case report

BackgroundShoulder injury related to vaccine administration, defined as shoulder pain and limited range of motion occurring after administration in the upper arm, has been previously reported. The symptom resolved completely after treatment with oral nonsteroidal anti-inflammatory drugs or an intraarticular steroid injection, however there have been few reports of long-term symptoms following coronavirus disease 2019 vaccination. This case report describes a healthy, middle-aged, healthcare worker who developed post-vaccination subacromial–subdeltoid bursitis that lasted for more than 6 months after Pfizer–BioNTech coronavirus disease 2019 vaccination.Case presentationA 55-year-old Japanese woman with no significant medical history was vaccinated in the standard site, with the needle direction perpendicular to the skin. Within a few hours after the second vaccination, severe shoulder pain and limited range of motion appeared. Although shoulder range of motion improved, her shoulder pain did not improved for several months, and she consulted an orthopedic doctor 5 months later. Radiographs of her left shoulder did not provide helpful diagnostic information. High intensity in the subacromial–subdeltoid space was seen on short TI inversion recovery of magnetic resonance imaging, showing subacromial–subdeltoid bursitis. She was diagnosed with a shoulder injury related to vaccine administration. The patient was started on an oral anti-inflammatory drug, and the left subacromial space was injected with 2.5 mg of betamethasone with 3 ml of 1% lidocaine without epinephrine every 2 weeks. One month after starting this treatment, since her shoulder pain had not improved, the oral anti-inflammatory drug was switched to tramadol hydrochloride acetaminophen. However, 3 months after switching medication, the shoulder pain continued, and she worked so as to have minimal impact on her shoulder.ConclusionA case of subacromial–subdeltoid bursitis following a second dose of the Pfizer–BioNTech coronavirus disease 2019 vaccine that lasted many months is reported. Injection technique is a modifiable risk factor, the adverse effects of which could potentially be mitigated with appropriate and relevant training of healthcare providers. To prevent this type of case, the appropriate landmark, needle length, and direction should be confirmed.

Clinical Impairments and Rotator Cuff Tendon Pathology in Primary and Intrinsic Secondary Adhesive Capsulitis.

This study was conducted to compare the differences in clinical impairments between patients with primary and intrinsic secondary adhesive capsulitis and confirm rotator cuff tendon pathology in intrinsic secondary adhesive capsulitis. This study included 130 patients with unilateral adhesive capsulitis in freezing or frozen stages. Clinical impairment was evaluated using visual analog scale score, shoulder passive range of motion, Cyriax stage, and Constant-Murley score. Plain radiography, ultrasonography, single-contrast arthrography, and intravenous gadolinium-enhanced magnetic resonance imaging were performed in all patients. Among 130 patients, 77 patients were diagnosed as primary adhesive capsulitis and 53 patients as intrinsic secondary adhesive capsulitis. Among intrinsic secondary adhesive capsulitis patients, 44 rotator cuff tendon tears, 6 calcific tendinitis, and 3 rotator cuff tendon tears with calcific tendinitis were observed. No significant intergroup difference was observed in all clinical parameters, including shoulder passive range of motion, visual analog scale, Cyriax stage, and Constant-Murley score. The prevalence of subacromial subdeltoid bursitis was significantly higher in intrinsic secondary adhesive capsulitis compared with primary adhesive capsulitis. There was no significant difference in all clinical parameters investigated between patients with primary and intrinsic secondary adhesive capsulitis caused by rotator cuff tendon pathology.

Shoulder ultrasound imaging in the post-stroke population: a systematic review and meta-analysis.

Post-stroke shoulder pain is a serious challenge for stroke survivors. The aim of this meta-analysis was to review the literature to confirm information on structural changes in post-stroke shoulders detected by ultrasound examination. PubMed, Embase, Web of Science and ClinicalTrials.gov were searched until 7 December 2022, for studies describing shoulder sonographic findings in stroke patients. Two independent authors selected the studies, extracted the data, and performed the critical appraisal. A total of 23 clinical studies were included. The most prevalent pathologies in hemiplegic shoulders pertained to the biceps long head tendon (41.4%), followed by the supraspinatus tendon (33.2%), subdeltoid bursa (29.3%), acromioclavicular joint (15.0%), and subscapularis tendon (9.2%). The common pathological findings encompassed bicipital peritendinous effusion (39.2%), biceps tendinopathy (35.5%), subdeltoid bursitis (29.3%) and supraspinatus tendinopathy (24.6%). Biceps long head tendon and supraspinatus tendon abnormalities were observed significantly more in the hemiplegic (vs contralateral) shoulders, with odds ratios of 3.814 (95% confidence interval 2.044-7.117) and 2.101 (95% confidence interval 1.257-3.512), respectively. No correlation was observed between motor function and shoulder pathology. Ultrasonography enabled the identification of common shoulder pathologies after stroke. Further research is needed to establish the association between these changes and the clinical course of stroke patients.

SIRVA: Shoulder injury related to vaccine administration.

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. It has been hypothesized that this is associated with a vaccine injection site that is "too high" and predisposes to the development of SIRVA. Nerve conduction studies are routinely normal, but further imaging can reveal deep-deltoid collections, rotator cuff tendinopathy and tears, or subacromial subdeltoid bursitis. However, all of these are common findings within a general asymptomatic population. Medicolegal claims in the UK, based on an incorrect injection site, are unlikely to meet the legal threshold to determine liability.

External to internal glenohumeral strength ratio in non-traumatic rotator cuff pathologies.

A correct agonist -antagonist strength relationship for shoulder external and internal rotation is necessary for functional stability of the shoulder. This strength relationship is described by the ratio of external to internal strength (ER/IR).The aim of this stydy is to produce comparative data as regards the ER/IR ratio in subjects with different non-traumatic rotator cuff diseases. A cross-sectional study in an outpatient clinic in a tertiary care university hospital. In 55 subjects with rotator cuff disease (confirmed by physical examination and assessed by ultrasound and magnetic resonance arthrography), the ER/IR ratio of the shoulder was isometrically measured with a hand-held dynamometer and compared with values pertaining to the unaffected shoulder of the same individuals. The mean ER/IR values in the overall group were 0.89 (SD 0.18) and 0.94 (SD 0.22) for the affected and unaffected shoulders, respectively. The ratio was 0.87 (SD 0.23) in patients with subdeltoid bursitis, 0.88 (SD 0.16) in rotator cuff tendinopathy and 0.87 (SD 0.22) in patients with rotator cuff tears. The ER/IR ratio appears to be similar between the affected and unaffected shoulders of subjects with nontraumatic cuff pathologies.

Chronic stage magnetic resonance imaging findings in patients with shoulder injury related to vaccine administration (SIRVA)

PurposeIdentify chronic shoulder MRI findings in patients with known shoulder injury related to vaccine administration (SIRVA).Materials and methodsTwo fellowship-trained musculoskeletal radiologists retrospectively reviewed the MRI of nine patients with clinically established SIRVA. MRI was performed at least 4 weeks after vaccination and included intravenous contrast-enhanced sequences. MRI was reviewed for the presence of erosions, tendonitis, capsulitis, synovitis, bone marrow oedema, joint effusion, bursitis, cartilage defects, rotator cuff lesions, and lymphadenopathy. The number and location of focal lesions were recorded.ResultsErosions of the greater tuberosity were present in 8/9 (89%), tendonitis of the infraspinatus muscle tendon in 7/9 (78%), capsulitis, synovitis, and bone marrow oedema in 5/9 (56%) cases, respectively. Effusion was found in three, and subdeltoid bursitis, rotator cuff lesions as well as cartilage defects in one patient, respectively. None of our included subjects showed axillary lymphadenopathy.ConclusionIn this case series, greater humeral tuberosity erosions, infraspinatus muscle tendonitis, capsulitis, synovitis, and bone marrow oedema were common MRI findings in chronic SIRVA.

Clicking shoulder due to snapping Subacromial subdeltoid (SASD) bursitis: a case report of an unusual presentation in clinical practice with imaging features.

A spectrum of pathologies can cause clicking, popping or snapping of the shoulder joint. These can lead to a patient seeking attention in clinical practice due to pain, discomfort and impact on activities of daily living. Traditionally these can originate from pathologies which involve biceps tendon, tears of the rotator cuff or the glenoid labrum, articular cartilage or due to loose bodies and scapulothoracic joint dysfunction [Guillin et al. in Br J Radiol 85:1343-1353, 2012; Vidoni et al. in Indian J Musculoskelet Radiol 4:61-69, 2022]. Subacromial subdeltoid (SASD) bursitis is a well-described entity and one of the commonest causes of shoulder pain. We present SASD bursitis as an unusual cause of clicking/snapping in the shoulder without associated pain in a healthy young male. The clinical presentation, diagnostic strategy with complementary imaging and the role of interventional radiology in its effective management is highlighted to support clinicians faced with a diagnostic dilemma.

Massive “risotto bursitis” of the great trochanter bursa after proximal femoral varus osteotomy with 5,0 LCP- a case report

The “risotto phenomenon” is a rare pathologic finding, mostly seen as a nonspecific response to chronic inflammation around the shoulder joint- subacromial and subdeltoid bursitis, rheumatoid arthritis, sero-negative inflammatory arthritis, septic arthritis and tuberculous arthritis. A few scientific reports associate rice body formation with the use of different type of osteosynthesis, bony anchors and bioabsorbable sutures. They are usually an incidental asymptomatic finding, requiring no specific treatment, but could be symptomatic demanding surgical excision. We present the clinical case of a 17-year- old female patient with a “risotto bursitis” of the great trochanter bursa, documented during planned surgical removal of a locking compression plate after proximal femoral varus osteotomy for bilateral developmental dysplasia of the hip treatment.

Ultrasonography of Shoulder in Rheumatoid Arthritis: A Reliability Exercise Using Consensual Definitions among Maghrebian Rheumatologists

The shoulder may be affected in a large portion of patients with rheumatoid arthritis (RA) worldwide. However, this joint does not receive the attention required during follow-up. Indeed, although numerous clinical tests for diagnosis of a painful shoulder are available, differentiating articular from peri-articular lesions may be difficult in daily practice. Fortunately, the precise diagnosis of shoulder pain in RA has benefited from a reliable imaging modality used to detect its exact origin-ultrasonography (US). This study was aimed at assessing the intra- and inter-observer reliability of ultrasonographic findings for patients with established RA with shoulder pain in a patient-based exercise as a clinical challenge among Maghrebian rheumatologist experts in US. A total of 7 operators examined 10 patients in two rounds independently and blindly of each other. Before beginning the session, all of the rheumatologists reached a consensus on sites and US settings by performing a brief exercise on a normal shoulder. Outcome Measures in Rheumatology Clinical Trials (OMERACT) definitions of US-detected pathologies were used. Each patient underwent US scanning of the painful shoulder in predefined sites based on US technical guidelines of the European Society of Musculoskeletal Radiology: long head of biceps (LHB), subscapularis recess, posterior recess and axillary recess. The presence of subdeltoid or subcoracoid bursitis or full rupture of the suprasupinatus was identified if present. Intra- and inter-observer reliability measures were calculated using the κ coefficient. Intra-observer reliability was good for gray-scale (GS) synovitis in subscapularis and posterior recesses (κ=0.77 and 0.73, respectively). It was moderate in the presence of GS synovitis and effusion in LHB (κ =0.53 and 0.40, respectively), posterior and subscapularis recess effusion (κ=0.56 and 0.60, respectively) and GS and power Doppler (PD) synovitis in axillary recesses (κ=0.58 and 0.49, respectively). Inter-observer reliability was good for PD for LHB signals (κ=0.78). It was moderate for GS for LHB synovitis (κ=0.54). Inter-observer agreement was poor for effusion and GS synovitis for subscapularis, posterior and axillary recesses, and very poor for PD signals in these recesses. US was a reliable imaging tool for detecting tenosynovitis in the LHB. However, reliability was moderate to poor in detecting synovitis in subscapularis, posterior and axillary recesses. These findings could be optimized by standardization of sites to assess.

Relationship between shoulder ultrasound findings and disease activity in patients with rheumatoid arthritis: A pilot study.

Objectives The aim of this study was to investigate whether shoulder ultrasound (US) findings were associated with disease activity and pain level in rheumatoid arthritis (RA) patients.Patients and methods Between April 2019 and November 2019, a total of 60 shoulders of 30 female patients with RA (mean age: 53.8±12.0 years; range, 30 to 65 years) were included. The patients were questioned about shoulder pain and their Disease Activity Score-28 (DAS28) was estimated. After clinical examination with shoulder impingement tests, both shoulders were evaluated by US.Results Of 60 shoulders examined by shoulder US, the most common shoulder pathology was supraspinatus tendinopathy (n=33, 55%). The prevalence of subdeltoid bursitis on US was significantly higher in the group with moderate disease activity, compared to the group with low disease activity (p<0.05). There were no significant differences in the physical examination findings of patients with low and moderate disease activity. In terms of US findings, subscapularis tendinopathy, glenohumeral joint and acromioclavicular joint degeneration, and subacromial bursitis were more common in shoulders with a history of pain, compared to non-painful shoulders.Conclusion Shoulder US may be useful for demonstrating shoulder involvement in patients with RA, independent of the presence of shoulder pain.

Subacromial impingement syndrome: association of multiple magnetic resonance imaging parameters with shoulder function and pain

IntroductionShoulder pain is one of the most common complaints in orthopaedics. This study focusses on the relationship between shoulder function in subacromial impingement syndrome and imaging criteria in magnetic resonance imaging (MRI).Materials and methodsThis prospective clinical trial included 69 patients treated for subacromial impingement syndrome. Shoulder function (Constant Score, range of abduction, abduction force) and pain were correlated with the following MRI parameters: tendinosis of the rotator cuff, “halo-sign” around the biceps tendon, subacromial distance, critical shoulder angle, size of subacromial osteophytic spurs and maximum width of subacromial and subdeltoid bursa. Statistical analyses included Pearson’s and Spearman’s coefficients of correlation, multiple regression analysis and Student’s t-test.ResultsThe Constant Score was correlated positively with the critical shoulder angle (r = 0.313; p = 0.009) and inversely with a “halo-sign” around the biceps tendon (rho = −0.384; p = 0.001). There was no significant correlation between spur size and shoulder function, but the size of the subacromial and subdeltoid bursae was positively correlated with the subacromial spur’s size (subacromial bursa: coronal plane: r = 0.327; p = 0.006; sagittal view: r = 0.305; p = 0.011; subdeltoid bursa coronal view: r = 0.333 p = 0.005). The width of the subdeltoid bursa in coronal plane was positively correlated with shoulder pain (r = 0.248; p = 0.004) and negatively with the range of abduction (r = −0.270; p = 0.025), as well as the mean (r = −0.332; p = 0.005) and maximum (r = −0.334; p = 0.005) abduction force.ConclusionsShoulder function and pain in subacromial impingement are best predicted by the width of the subdeltoid bursa measured in the coronal MRI plane as an indicator of bursitis as well as the presence of a “halo-sign” around the biceps tendon indicating glenohumeral joint effusion. Presence of a subacromial spur could lead to subacromial and subdeltoid bursitis, which impairs shoulder function. Shoulder function seems not to be compromised by the presence of a subacromial spur in absence of bursitis.This study was registered at the German Clinical Trials Register on 08 February 2013 (ID: DRKS00011548).

Role of Magnetic Resonance Imaging and Ultrasonography in Evaluation of Chronic Non osseous Shoulder Pain.

Background: Chronic shoulder pain is a common clinical presentation. It is of osseous or non-osseous origin. In non-osseous shoulder pain, proper diagnosis is critical. Magnetic resonance imaging [MRI] is the standard diagnostic modality. However, it is expensive and not available in many medical centers. Thus, the availability of cheap alternative is crucial. Aim of the work: The current research aimed to assess the diagnostic performance of ultrasonography versus conventional MRI in different causes of chronic non-osseous shoulder pain. Patients and Methods: Fourty patients with chronic shoulder pain due to different causes were participated in the current work. They were selected from Al-Azhar University Hospital [Damietta]. All were assessed on clinical basis [history, physical examination and laboratory investigations]. Then, all were submitted to radiological investigations [Plain X-ray, shoulder ultrasound, and Magnetic resonance imaging]. The diagnostic value of ultrasound was estimated versus that of magnetic resonance imaging. Results: by ultrasound, tendinosis was reported in 55.0%, partial thickness tear in 27.5%, articular surface in 20.0%, full thickness tear in 12.5%, bursal surface [7.5%], neoplastic [2.5%] and infraspinatus tendon full thickness tear [2.5%]. Ultrasound able to diagnose supraspinatus tendinopathy [91.7%], full thickness complete tear [83.3%], supraspinatus impingement [85.3%], subacromial subdeltoid bursitis [92.0%] and long head biceps tenosynovitis [84.2%]. Otherwise, ultrasound specificity is over its sensitivity power for partial thinness tear on articular [80.0%] or bursal surfaces [85.3%], full thickness complete tear [94.1%], shoulder joint effusion [92.3%], LHB tenosynovitis [85.7%] and labral tears [100.0%]. Conclusion: Shoulder ultrasound could be considered as a reasonable alternative to magnetic resonance imaging in the diagnosis of different causes of chronic shoulder pain. However, its value widely different from condition to another. Thus, it could be used as a rapid screening tool, and the use of MRI could be ascribed for specific conditions [cases with lower ultrasound sensitivity].

Are subdeltoid bursitis and polymyalgia rheumatica preferances of COVID-19 vaccine?

COVID-19 vaccine became clear card life-saving medication. Due to over world vaccination a rate of prevalence and incidence of coronal infection is going to back down. However, we meet different side effects of the vaccine. Two cases of subdeltoid bursitis after COVID-19 vaccination discussed.

Ultrasonography as diagnostic tool in rotator cuff injuries of shoulder

Introduction: Rotator Cuff injuries are quite common in adults with or without trauma. These are suspected on clinical history and examination and commonly confirmed by Ultrasonography and MRI of shoulder. This study aims to use Ultrasonography of shoulder as the main diagnostic tool for such injuries. Material and Methods: A total of 30 patients suspected to have complete or incomplete tear of Rotator Cuff were subjected to Clinical Examination of Shoulder including specific tests for Rotator Cuff Muscles, X-ray and Ultrasonography of shoulder. Diagnosis by clinical examination and Ultrasonography was compared. Observation and Results: Out of 30 cases studied, on clinical examination, 10 cases had complete tear of supraspinatus, 19 cases had incomplete tear of supraspinatus with or without subscapularis, and 1 case had isolated subscapularis tear. Ultrasonography noted full thickness tear of supraspinatus in 8 cases, incomplete tear of supraspinatus with or without subscapularis, in 20 cases, bicipital tendinitis in 01 case and subacromial subdeltoid bursitis in 01 case. Conclusion: Ultrasonography confirms the clinical diagnosis of rotator cuff tear with satisfactory sensitivity and specificity. It can be used as a first line diagnostic tool for diagnosis of Rotator cuff tear as it confirms the clinical suspicion and its results are comparable to MRI.
