Evaluation of Shoulder Joint by MRI Through 61 Patients

INTRODUCTION Shoulder joint is a type of ball and socket joint that lies between the scapula and the humerus [1]. It is the most flexible joint in the body[2]. This flexibility provides the upper limbs with marvelous range of motion such as abduction, adduction, flexion, extension, internal and external rotation as well as circular motion. This wide range of movement makes the shoulder joint unstable [2]. This instability is compensated for by rotator cuff muscles, ligaments, tendons, and the glenoid labrum[3, 4, 5, 6, 7]. Shoulder pain is account for 5% of all musculoskeletal consultations [8]. Plain radiography is a useful tool in evaluation of shoulder joint pain [9]. Magnetic resonance imaging (MRI) is the best imaging modality when the plain radiography result is not satisfied. It has replaced all other medical imaging because of excellent soft tissue contrast and provides multiplanar imaging that not exist in other imaging modalities as well as it is a noninvasive tool.

MRI of shoulder instability: state of the art
Current problems in diagnostic radiology
In recent years, our understanding of normal anatomy and traumatic lesions of the glenoid labrum and the associated glenohumeral ligaments and joint capsule have grown substantially. Pathologic abnormalities are generally seen in individuals with an antecedent episode of shoulder trauma, typically involving a dislocation or a subluxation. These lesions can have a wide range of appearances and the radiologist must be familiar with them to make the correct diagnosis and avoid the potential pitfalls related to normal anatomic variations in the glenoid and capsuloligamentous structures. The purpose of this article is to review a variety of traumatic lesions involving the labral ligamentous complex in patients with glenohumeral instability. These lesions predominantly involve the inferior and anteroinferior supporting structures.
Assessment of Correlation Between MRI and Arthroscopic Pathologic Findings in the Shoulder Joint
The archives of bone and joint surgery, 2015
BACKGROUND The objective of this study was to determine the diagnostic value of magnetic resonance imaging for shoulder joint pathologies and then compare the results with arthroscopy, the standard for joint diagnosis. METHODS In this cross-sectional study, 80 patients with shoulder joint disorders, who underwent final arthroscopy, were studied. Based on patients' medical history and physical examinations, shoulder MRI was requested if paraclinical investigations were. If non-surgical therapies failed, arthroscopy of the affected shoulder was done and the same structures were inspected. Subsequently, sensitivity, specificity, and positive and negative predictive values (PPV) and (NPV) of MRI were determined by arthroscopy comparisons. RESULTS The highest sensitivity, specificity, PPV and NPV were found in MRI pathology reports that included: Hill-Sach lesion (0.910), infraspinatus tendon (0.985), supraspinatus tendon (0.930), and biceps tendon (0.954), respectively. Rotator inte...
The spectrum of MRI findings in painful shoulder: A prospective study of 81 cases
Background: Shoulder MRI is now considered the standard among the imaging methods to diagnose the etiology of shoulder pain as MRI allows the direct visualization of the rotator cuff tendons, their tears and abnormalities, their relationship to the undersurface of the acromion and the acromioclavicular (AC) joint and also identifies tears of labro-ligamentous complex. Objective: The purpose of this study was to highlight the MRI spectrum of various non-infective, nonneoplastic pathologies of shoulder joint in patients presenting with pain and to analyse the results statistically.
Selected Unique Clinical Shoulder Signs as Visualized by MRI
Shoulder pain is a common musculoskeletal complaint that if severe enough, can contribute significantly to morbidity due to its debilitating and often disabling nature which may leave patients unable to perform activities of daily living. Various etiologies of shoulder pain exist which present with clinical signs and symptoms based on the source of the pathology. Although most shoulder injuries can be diagnosed with a detailed history and physical exam, magnetic resonance imaging (MRI) has become a well-established technique for confirming pathology

Magnetic resonance imaging has developed as a useful imaging modality in the evaluation of the athlete with shoulder pain. The multiplanar capabilities of magnetic resonance imaging make it ideal for detecting the anatomical variations of the osseous outlet that may contribute to the clinical syndrome of impingement. Its superb soft tissue contrast and spatial resolution allow for accurate differentiation between tendinopathy, partial-thickness tear, and full-thickness tear of the rotator cuff and also allow for detection of the subtle lesions of the capsule and labrum that are associated with shoulder instability. However, to accurately interpret the numerous images and pulse sequences obtained in a standard magnetic resonance examination of the shoulder, it is helpful to have a systematic approach to ensure that each of the pertinent anatomical structures are evaluated. This article will provide a systematic approach to the interpretation of a magnetic resonance examination of the...
Normal anatomy, variants and pitfalls on shoulder MRI
European Journal of Radiology, 2008
MR imaging of the shoulder is widely used for assessment of impingement and instability-related clinical conditions. The following review article demonstrates the normal anatomy, variations and classical pitfalls. In addition to classical pitfalls (sublabral hole, sublabral recess, Buford complex) the authors focus on a number of normal, bony, cartilaginous, ligamentous and tendinous structures that can simulate disease at the shoulder. In addition, ways to distinguish these pitfalls from true shoulder abnormalities are shown.
