With the exception of distinguishing partial- from full-thickness rc tears and identifying the side of partial thickness tears (articular versus bursal rc classification systems have little interobserver agreement even among experienced shoulder surgeons.55. Classification of rotator cuff tears, numerous rotator-cuff-tear classification systems have been proposed.56-60 Though several are highly accurate, they are similarly complex and lack intraobserver and interobserver agreement. With an increasing emphasis on evidence-based medicine, mri descriptions of rc tears need to be accurate, simple, and precise with high interobserver agreement.61 Common pathology of the rc tendons includes full thickness tears, partial thickness tears, and tendinosis. Full thickness tears, an abnormality of the rotator cuff is considered a full thickness tear if it results in a connection between the articular and bursal surfaces of the cuff tendon. The most specific sign of a full thickness rc tear is visualization of a complete defect in the tendon, extending from the articular surface completely through to the bursal surface. This defect is usually fluid signal intensity as it is filled with fluid, organizing granulation tissue, myofibroblastic proliferation, chondroid metaplasia and/or hemorrhage.26,62 Fortunately, this appearance of full thickness tears is also the most common, seen approximately 87 of the time.63 Less commonly, full thickness defects. Secondary signs of a full thickness rc tear — fluid in the subacromial-subdeltoid bursa, muscle atrophy, intramuscular cysts, superior humeral migration, and retraction of the musculotendinous junction — used to be more heavily relied upon prior to higher-resolution mr capabilities and the routine use. Its worth mentioning that literature has demonstrated each of these secondary findings with partial thickness tears and even in patients without a tendon defect.68-71 to adequately detail full thickness rc tears, two descriptors should be used: the anteroposterior extent of the tear and the amount. Precise measurements for the anteroposterior extent of full thickness tears have been abandoned because of subjective variability and lack of reproducibility.
While nonoperative rehabilitation is successful in certain patient subgroups — predominately elderly patients with a sedentary lifestyle — early surgical repair is indicated in other patients, usually younger and more active individuals.34 Despite good to excellent results of surgical repair in a high percentage. Mri plays a significant role in evaluating the stage and prognosis of rc disease: tear size, tendon retraction, and the extent of muscle atrophy, each of which negatively impacts the functional outcome. The clinical function and mri appearance of rc tears deteriorate with time.30,37 Partial thickness tears of the anterior supraspinatus fibers increase strain upon the remaining supraspinatus fibers and intact arthritis infraspinatus tendon, leading to tear propagation and potentially impacting the decision to operate sooner as opposed. They added that tear size appears to have the most influential effect on repair integrity.41 Fatty degeneration of the rc is closely associated with tear size and location. In particular, integrity of the anterior supraspinatus tendon seems to be the most important variable related to fatty degeneration.42 A natural history of fatty infiltration relative to onset of shoulder symptoms was suggested by melis et al, with moderate fatty infiltration at 3 years and.hand
Diagnostic imaging, even though shoulder radiographs in acute rotator cuff tears are usually normal, they remain the appropriate first line of imaging to evaluate osseous structures and exclude common fractures and dislocations.45-47 While multiple radiographic maneuvers and techniques have been suggested to help diagnose. Mri can evaluate the size and shape of the tear, the amount of tendon retraction, the prominence of muscle atrophy, and the quality of remaining rc tendon. In addition, it can accurately evaluate other potential causes of shoulder pain that may mimic rc tears.48. Shoulder mri can detect full thickness rc tears with high sensitivity and specificity, but mri diagnosis of partial thickness tears is less sensitive and accurate. A large meta-analysis compiled in 2009 used a surgical reference standard and found pooled mri sensitivity and specificity for full thickness tears.1 and.9; for partial thickness tears.6 and.7; and for full or partial thickness tears.0 and.7. In 2006, magee reported sensitivity and specificity of 98 and 96, respectively, for full thickness supraspinatus tears and, even more impressive,.5 and 90, respectively, for partial thickness supraspinatus tears.52 The diagnostic accuracy of shoulder mri improves with experience and training.53,. Finally, the often-utilized gold standard of rotator cuff disease diagnosis — shoulder arthroscopy — is not without similar flaws.

This muscles attachment to the lesser tuberosity is comma shaped, with a broad proximal and tapering distal footprint.7,8 The subscapularis fibers extend over the bicipital groove, and the superior fibers of the subscapularis tendon interdigitate with the anterior fibers of the supraspinatus tendon over the. Demographics of rotator cuff pathology, shoulder pain is extremely common with reports that approximately half the. Population experiences at least one episode of shoulder pain annually.10 The prevalence of shoulder pain substantially increases with age, and the most common musculoskeletal complaint in patients 65 is shoulder pain.11 As rotator cuff tears are often asymptomatic, their true prevalence remains unknown and reports. Their analysis also suggested risk factors for rc tears: a history of trauma, dominant arm, and older age.13 A high correlation between the onset of rc tears and increasing age has also been reported in several other studies — in one, 50 of patients. More surprising, however, are prevalences of 50 in the seventh decade and 80 in the 9th and 10th decades.16 These studies confirm that rc tears are extremely common, especially in the elderly, and that it is important to remember that their presence does not always. Pathogenesis of rc pathology, although the true pathogenesis of rotator cuff tears remains unclear, mechanisms of rc degeneration are broadly divided into extrinsic and intrinsic factors.
In reality, rc tears are probably a multifactorial byproduct of the interaction of intrinsic and extrinsic causes.18 In 1934, codman espoused the intrinsic theory that age-related tendon damage compounded by chronic microtrauma results in partial thickness tears, which usually then progress to full thickness tears.19. Clinical presentation, evaluation, and management, patients with symptomatic rotator cuff tears usually present with shoulder pain, dysfunction, or both. Classic clinical teaching suggests that these symptoms are more significant in patients with subacromial bursitis and/or partial thickness rc tears compared to those with full thickness tears. Fukuda further reports that bursal-sided tears are more painful than articular-sided tears.30 However, a more recent study by Brownlow et al relates that no statistical difference exists, and that neither pain nor stiffness can reliably differentiate partial and full-thickness tears.31. Clinical evaluation is the first step toward diagnosing rc disease. Clinicians often rely upon a battery of tests to evaluate and classify patients appropriately. A meta-analysis suggests that the diagnostic accuracy of orthopedic shoulder exams is overestimated, and that these exams are only rarely useful to differentiate rc tears. While some shoulder examination tests had high sensitivities and others had high specificities, no single test had both a high specificity and a high sensitivity.32 Further, the lack of precise techniques and subjective interpretation of these exams leads to substantial interobserver variability.33. Management of partial and full thickness rc tears remains largely controversial.
Subchondral cyst acetabulum - things you didnt Know
Much has been written recently about the anatomy of distal rc tendons as they interdigitate to insert upon the 3 facets of the greater tuberosity (superior, middle, and inferior although their location and insertion appear somewhat more arbitrary by mr imaging. Standard landmarks and techniques used in mri to demarcate the tendons will be elaborated upon later. The supraspinatus muscle arises from the posterior aspect of the scapula, just muscle above the scapular spine, and courses horizontally and anteriorly at the level of the acromioclavicular joint, a good landmark for its musculotendinous junction. The subacromial-subdeltoid bursa, which usually contains minimal fluid, if any, drapes over the supraspinatus muscle and tendon and lies just beneath the acromion. While most anatomy laboratories still teach that the supraspinatus has a broad footprint, more recent anatomic and orthopedic literature suggests that it has a relatively small triangular footprint on the superior facet of the greater tuberosity.1,2 Importantly, the larger anterior portion of the supraspinatus muscle. The infraspinatus blood muscle arises from the posterior aspect of the scapula, below the scapular spine. It then courses laterally, with the anterior border of the infraspinatus tendon insertion overlapping the posterior border of the supraspinatus tendon, to attach to the entire middle facet interdigitating with the supraspinatus tendon at the posterior aspect of the superior facet.2 The teres minor muscle. The large, triangular subscapularis muscle arises from the anterior surface of the scapula and courses laterally under the coracoid, with its musculotendinous junction at the level of the glenoid.

The interconnected supraspinatus, infraspinatus, teres minor, and subscapularis musculotendinous complexes constitute the rotator cuff and act as the shoulders primary functional unit. Because of baarmoedermond the rotator cuffs crucial role, rc pathology may lead to considerable limitations in daily routine, work, and leisure/sporting activities. Shoulder magnetic resonance imaging (MRI) improves the sensitivity and specificity of diagnosing rc disorders, reduces unnecessary arthroscopic procedures, and provides important clinical information to guide patient management. This review will cover recent literature regarding rc anatomy and the clinical presentation, evaluation, and management of rc disease. We will discuss new observations about the strengths, inherent blind spots, and diagnostic effectiveness of shoulder mri, and then outline the classification of rotator cuff mri findings and their impact on patient management. Finally, we will present an effective search pattern approach to evaluate the rotator cuff on shoulder mri examinations. Normal anatomy, knowledge of the rc tendinous insertions onto the proximal humerus, an area known as the rotator cuff footprint, makes it easier to determine the extent and location of abnormality.

Linking the axial trunk and upper extremity, the shoulder joint plays an imperative role in most daily activities, allowing us to position our hands in space. Further, the joint acts as a small fulcrum for a long lever arm, predisposing the rotator cuff to injury, especially from the rapid accelerations and decelerations inherent piercing to most sports and even some activities of daily living. Shoulder anatomy and biomechanics, particularly those of the rotator cuff (rc endow the glenohumeral joint with dynamic and static stability throughout a substantial range of motion.

Subchondral cyst humeral head - what are the problems vrouw seen with subchondral cysts on humeral head? If assosciated with pain and limitation of movement of the shoulder then denotes osteoarthritis of the shoulder. We obtained mr images of 140 painful shoulders in 134 patients to determine the relationship between cystic changes of the humeral head and integrity of the rotator cuff. Cystic changes were observed in 49 shoulders (35) and the commonest site was in the bare bone area of the anatomical neck, and the second commonest site was at the attachment of the supraspinatus tendon. Cystic changes of the humeral head.
was in the bare bone area of the anatomical neck, and the second commonest site was at the attachment of the supraspinatus tendon. Cystic changes in the bare bone area were observed equally often in shoulders with or without rotator cuff tears (27 and 18, respectively) and were more frequently observed in the elderly. Cystic changes at the attachment of the supraspinatus and subscapularis tendons were specific to rotator cuff tears: they were observed in 28 of rotator cuff tears, but in none of those with an intact cuff. We conclude that there are two distinct types of cystic changes: one at the attachment of the supraspinatus and subscapularis tendons, which is closely related to tears of these tendons, and the other in the bare bone area of the anatomical neck, which is related.
