Background: Very little comparative information is available regarding the demographic and morphological characteristics of asymptomatic and symptomatic rotator cuff tears. This information is important to provide insight into the natural history of rotator cuff disease and to identify which factors may be important in the development of pain. The purpose of the present study was to compare the morphological characteristics and prevalences of asymptomatic and symptomatic rotator cuff disease in patients who presented with unilateral shoulder pain.
Background: Shoulder pain is a common cause of morbidity in the general adult population. Magnetic resonance imaging (MRI) is a sensitive and accurate non-invasive tool in investigating rotator cuff pathology and adjacent bone, because of its Multiplanar capability and excellent soft tissue resolution. Hence; the present study was undertaken for assessing MRI imaging of adjacent bone in patients of rotary cuff tendon. Methods: A total of 112 patients were enrolled. A Performa was made and complete demographic and clinical details of all the patients were recorded. MRI procedure was carried out in all the patients. All the MRI procedures were carried out by skilled and experienced radiologists. The acromial shapes were classified into type I (flat), type II (curved), type III (hooked) and type IV (convex). All the results were recorded in Microsoft excel sheet excel sheet and were analysed by SPSS software. Results: Type I acromion was found to be present in 21 patients, while type II acromion was found to be present in 65 patients. After analysing joint effusion on MRI in patients with rotator cuff tendon pathologies, it was seen that tear was found to be present in 62.5 percent of the patients while Tendinosis was present in 17.86 percent of the patients. While analyzing the association of acromio-humeral distance and supraspinatus tendon pathology, significant results were obtained. While adjacent bone changes associated with rotator cuff pathologies, it was seen that edema/contusion of humeral head was present in 33.04 percent of the patients. Subchondral cyst/ geode was present in 16.96 percent of the patients. Conclusions: MRI is the preferred test and significantly efficacious in evaluating shoulder bones in patient with rotator cuff pathology. We recommend that state-of-the-art conventional MRI, including fat-suppression sequences.

The imaging modalities used for evaluation of rotator cuff pathologies are USG and MRI.USG is less time consuming and cost effective modality for detection of rotator cuff pathologies. This study is done to compare the efficiency of USG in detection of shoulder pathologies when compared to MRI.
Mri in the Evaluation of Rotator Cuff Tendons in Chronic Shoulder Pain
Journal of Chitwan Medical College
Background: Shoulder pain is the third most common cause of non- traumatic musculoskeletal pain with rotator cuff pathology being the most common cause. Magnetic Resonance Imaging (MRI) is the imaging modality of choice which helps in accurate diagnosis for making a treatment plan as wrong treatment strategy may lead to poor prognosis. Methods: A descriptive prospective study conducted in 100 individuals with non-traumatic chronic shoulder pain referred to referred to Department of Radiodiagnosis and Imaging, Dhulikhel Hospital, Kavre between 27th August 2020 to 29th August 2021. MRI images were acquired and analyzed by using IBM SPSS 21.0 version Pearson correlation coefficient, Spearman correlation and chi square tests were used for statistical analysis. Results: Rotator cuff pathology was most commonly encountered with supraspinatus being the most frequently involved tendon seen in 28(63.6%), followed by subscapularis 10(22.7%), infraspinatus 4(9%) and teres minor 2(4.5%).Similar...
Assessment Acromion Morphology Association Shoulder Impingement Syndrome MRI
Society for Scientific Research, 2023
Background: The third most common musculoskeletal symptom in orthopaedic clinical practice is a sore shoulder, which can cause significant morbidity. It has been reported that 7–27% of the general population has it, and 36–66% of overhead arm athletes have it. Pathophysiology includes functional, degenerative, and mechanical factors. Most shoulder pain is subacromial pain syndrome (SAPS), often known as ‘shoulder impingement syndrome’. Impingement hypothesis: shoulder joint structures mechanically clash. SAPS accounts for 36–48% of shoulder discomfort. Methods: This observational study was conducted in the Department of Orthopaedics, MKCG Medical College and Hospital, Berhampur, among Eastern Indian outpatients. The study included adult patients (ages 18–75) of both sexes who presented to MKCG Medical College and Hospital's OPD with shoulder pain from December 2020 to November 2022 and were diagnosed with Shoulder Impingement Syndrome (SIS). Thorough histories and clinical exams were done. The Department of Radiology, MKCG Medical College and Hospital, Berhampur, performed conventional shoulder MRIs on the selected participants. Results: Most cases and controls were Type-II (43.3%), followed by Type-I (28.3% and 30%, 29.2% of the total group). The study's least common acromial shape was type-IV, seen in 5% of cases and 10% of controls (7.5% of the sample). Fisher's exact test showed no significant connection between subacromial impingement and acromial shape (p=0.65). With a p-value of 0.045, cases had a significantly greater acromial width (8.12±2.16 mm) than controls (7.51±0.81 mm). Conclusion: Sub-acromial impingement was unrelated to acromion morphology. There was no correlation between acromial morphology and rotator cuff injuries.
Glenoid axis is not related with rotator cuff tears—a magnetic resonance imaging comparative study
International Orthopaedics, 2012
Purpose The relationship between glenoid version angle and rotator cuff pathology has been described. However, the effect of glenoid version angle on rotator cuff pathology is still unknown. The aim of this study was to investigate whether there is an impact of glenoid version angle on rotator cuff pathology. Methods All shoulder MRI examinations performed in the study centres between August 2008 and August 2009 were evaluated retrospectively. Shoulder MRI examinations having rotator cuff pathology such as trauma, degeneration, and acromion type 2-3-4 reported in previous studies were excluded from the study. Sixty-two shoulder MRIs with rotator cuff pathology having type 1 acromion morphology and 60 shoulder exams without rotator cuff pathology were included in the study. Glenoid version angle was calculated in axial images. Rotator cuff was evaluated in fatsuppressed T2-weighted and proton density-weighted images.
Evaluation of non-articular causes of shoulder pain
International journal of health sciences
Background: To evaluate the accuracy of high resolution ultrasound (USG) and MRI in the diagnosis of rotator cuff tears (RCT) and to determine if high resolution USG compares favorably in sensitivity and specificity to MRI in the diagnosis of non-articular causes of joint pain. Material/Methods: In this prospective comparative study, 52 patients with clinically suspected rotator cuff tears underwent both ultrasound and MRI of the shoulder. The USG and MRI were interpreted by two radiologists experienced in musculoskeletal radiology and blinded to findings of each other. Comparison was done using MRI as a standard reference. Results: The agreement between USG and MRI for diagnosis of RCTs was statistically significant ; USG showed a sensitivity of 90.6% and a specificity of 75% for tendinopathy, a sensitivity of 64.3% and a specificity of 81.6% for partial-thickness tears, a sensitivity of 41.7% and a specificity of 90% for complete width full-thickness tears and a sensitivity of 40%...
Role of Magnetic Resonance Imaging in the Evaluation of Rotator Cuff Tears
Cureus, 2022
Background Magnetic resonance imaging (MRI), with the advent of surface coils, is becoming the modality of choice for imaging soft tissues around the shoulder joint. Good knowledge regarding the MR characteristics of rotator cuff tendons, acromion, and the abnormalities in these tendons is necessary for appropriate diagnosis. Methods This was a hospital-based descriptive, analytical and prospective study conducted at our tertiary care hospital. The study was performed on 50 patients with rotator cuff lesions detected on MRI of the shoulder joint. Results The age distribution found in the study is between 19 and 66 years with mean being 43 ± 14.8 years. The peak incidence was found in the fifth and sixth decades of life. Gender-wise distribution of rotator cuff pathologies has shown no significant gender variation. The pain was the most common presenting complaint. An abnormal supraspinatus tendon was seen in 82% of the 50 study patients, making it the most commonly affected tendons, followed by subscapularis and infraspinatus tendons. No apparent teres minor pathology was identified in the study patients. The most common pathology affecting the supraspinatus tendon was tendinosis (38%) closely followed by a partial tear (36%). Among the partial tears, the articular surface type of tear was the most common. About 52% patients had type II (curved) acromion; making it the most common type of acromion followed by type III (hook), supraspinatus tendinopathy was more common in type II acromion. A reduction in the acromiohumeral distance can cause supraspinatus tendinosis and also makes it more susceptible to tear. About 45.5% showed supraspinatus tendon tears when the acromiohumeral distance was less than 8mm as compared to 13.6% when more than 10mm. Only 4.2% had normal supraspinatus tendon in patients with this distance less than 7mm. Conclusion MRI provides valuable information to the orthopaedic surgeon regarding the status of tendons, bones, and joints. In order to choose the appropriate course of action, it is crucial first to identify the issue and report relevant data from rotator cuff imaging. A full grasp of the rotator cuff's architecture and function, as well as the repercussions of rotator cuff diseases, is required.
