J Shoulder Elbow Surg 2023; 32:2467-2472. [PMID: 37290637 PMCID: PMC10698205 DOI: 10.1016/j.jse.2023.05.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 04/20/2023] [Accepted: 05/02/2023] [Indexed: 06/10/2023]
Abstract
BACKGROUND In the presence of an isolated supraspinatus tear, the force applied to the greater tuberosity is reduced, which may lead to bony morphologic changes. Thus, diagnostic or surgical identification of landmarks to properly repair the torn tendon might be difficult if the anatomy of the greater tuberosity is altered. The objectives of the study were to assess the presence of the superior, middle, and inferior facets of the greater tuberosity in individuals with symptomatic isolated supraspinatus tendon tears and the associations between tear size, tear location and presence of each facet. METHODS Thirty-seven individuals with symptomatic isolated supraspinatus tendon tears were recruited to participate in the study. Individuals underwent a high-resolution computed tomography scan of the involved shoulder and images were segmented to generate subject specific models of each humerus. The vertices comprising each facet were identified; however, if even a single vertex comprising the facet was missing, the facet was considered altered. Percentage agreement for correctly identifying the presence of each facet was determined using 2 additional observers and 5 randomly selected humeri. Ultrasonography was performed to assess anterior-posterior (AP) tear size and tear location. Outcome parameters included presence of the superior, middle, and inferior facets; AP tear size; and tear location. Point-biserial correlations were used to determine the associations between AP tear size, tear location, and presence of the superior, middle, and inferior facets. RESULTS Supraspinatus tear size and tear location was 13.1 ± 6.1 mm (range, 1.9-28.3 mm) and 2.0 ± 4.4 mm from the posterior edge of the long head of the biceps tendon (range, 0.0-19.0 mm), respectively. Overall, the superior, middle, and inferior facets were not altered in 24.3%, 29.7%, and 45.9% of individuals, respectively. Percentage agreement between observers was 83.4% on average. No associations were found between tear size or tear location and presence of the superior, middle, or inferior facet (P values ranged from .19 to .74). CONCLUSION Individuals with symptomatic isolated supraspinatus tears experience significant alterations in the bony morphology of the greater tuberosity that were irrespective of supraspinatus tear size and location. This information is useful for radiologists and orthopedic surgeons as the altered anatomy may influence the ability to identify important anatomic landmarks during diagnostic imaging or surgical procedures.

Ultrasound Features Associated With Shoulder Complaints: Calcifications Larger Than 6 mm in Young Patients and Positive Doppler Are Associated With Pain. Front Med (Lausanne) 2021; 8:715423. [PMID: 34869414 PMCID: PMC8639518 DOI: 10.3389/fmed.2021.715423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2021] [Accepted: 10/28/2021] [Indexed: 11/13/2022] Open
Abstract
Objectives: To identify ultrasound (US) features associated with the presence of shoulder complaints. Methods: This observational, case-control study, compared US findings between participants with and without shoulder complaints, matched for age, sex, and dominancy. Data was collected from February 2018 to June 2020. Two-tailed Fisher's and Mann-Whitney U-tests were used, with p-values < 0.05 considered significant. Results: A total of 202 participants were enrolled (median age 56 years, range 18–70, 155 women), comprising 140 cases and 62 controls. A calcification size ≥6 mm, when age < 56 (p = 0.02), and a distance to tendon insertion ≥6 mm, when age ≥56 (p = 0.009), were only found in symptomatic shoulders. Color Doppler in rotator cuff (RC) tendons predominated in the presence of symptoms (26/140 vs. 2/62, p = 0.003). An algorithm also combining the number of calcifications, tendon echotexture and insertional thickening, osseous irregularity, cuff tears, and subacromial effusion showed a 92% (57/62) specificity for shoulder pain on this study sample. Conclusion: Calcification diameter of 6 mm or more is associated with shoulder pain in patients younger than 56 years. A distance from calcification to tendon insertion of 6 mm or more is related to pain in older patients. Doppler signal also is associated with shoulder pain. An algorithm based on a set of specific ultrasonographic criteria have a strong association with the presence of symptoms.

Abstract
The rotator cuff is a group of four muscles and tendons surrounding the shoulder joint providing it strength and stability. The rotator cuff consists of the subscapularis, supraspinatus, infraspinatus and teres minor. Many shoulder complaints are caused by rotator cuff pathology such as impingement syndrome, tendon tears and other diseases e.g. calcific tendonitis. Diagnosis starts with clinical history and physical examination, after which imaging is often used to help confirm clinical findings depending on the differential diagnosis. The aim of the article is to review the frequently used imaging modalities to assess the rotator cuff and cuff-related disease, specifically focusing on radiography, ultrasonography and magnetic resonance imaging. This article will outline the advantages and disadvantages for each modality and illustrate typical radiological findings of common rotator cuff pathologies.

Abstract
Imaging evaluation of the shoulder is performed using multiple modalities, including ultrasound (US) and MR imaging. Clinicians often wonder which modality to use to work up their patients with shoulder pain. Although MR imaging has remained the workhorse of shoulder imaging, US has increased in popularity among academic and private institutions. Both modalities offer similar diagnostic information in regards to rotator cuff pathology and other soft tissues, although they differ in their technique, indications, and interpretation. A thorough understanding of these differences is imperative to appropriately use these modalities in clinical practice, including the unique interventional opportunities available with US.

Abstract
PURPOSE The purpose of this study is to identify radiographic risk factors (RRFs) and radiographic signs of abductor tendon tears. METHODS Between April 2008 and October 2015, patients with intraoperative diagnosis of partial- or full-thickness abductor tear noted at the time of open or endoscopic treatment were included in this study. Exclusion criteria included lack of preoperative standard supine pelvic radiograph, lack of preoperative magnetic resonance imaging (MRI), or abductor tear not present at the time of operative intervention. Patients were matched by age ±5 years, gender, and body mass index ±5 with patients with no abductor pathology by clinical exam and MRI. A standardized supine anterior-posterior pelvis radiograph was performed on all patients. The radiographs were evaluated for RRF (pelvic width, body weight moment arm, abductor moment arm, abductor angle, pelvic height) and signs of abductor tendon pathology (greater trochanteric enthesophyte). Femoral version was measured on MRI when images were available. Statistical analysis was performed and included bivariate and multivariate analyses. RESULTS There were 152 patients with abductor tears identified at the time of surgery out of 2,838 eligible patients matched with 125 patients without abductor tendon pathology. The study institution was unable to perform a 1:1 match because of the advanced age of the abductor tendon group, which led to a greater age in the abductor group (n = 58) versus the control group (n = 54; P = .01. In abductor group the average age was 58, and 137 of 152 (90%) patients were female; in the control group the average age was 54, with 111 of 125 (89%) patients being female. Abductor tear patients were treated with surgical repair. The RRFs found with bivariate analysis were an increased pelvic width (14.8 cm for abductor tears vs 14.3 cm for control; P < .001), body weight moment arm (11.1 cm vs 10.9 cm; P < .001), and abductor moment arm (7.8 cm vs 7.6 cm; P < .001); decreased femoral anteversion (7.6° vs 10.6°; P = .045); and enthesophyte presence (41% vs 3%; P < .001). Multivariate regression analysis of all variables showed that teardrop distance and enthesophyte presence were the 2 variables most predictive of abductor tears, and other variables did not significantly increase or decrease the likelihood of tear when these 2 variables were considered. The presence of an enthesophyte on the greater trochanter was notable for an odds ratio of 20.7 of having an abductor tear. CONCLUSIONS Patients with abductor tears have a wider pelvis, longer abductor moment arm, and longer body weight moment arm and have greater trochanteric enthesophyte as noted on nearly half of patients with an abductor tear. Presence of an enthesophyte was noted to have an odds ratio of 20.7 and a positive predictive value of 94% for having an abductor tendon tear. The 2 variables predictive of abductor tendon tear when controlling for all variables were enthesophyte presence and teardrop distance, with no other variables significantly increasing or decreasing the likelihood of tear when these 2 variables were considered. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
Shoulder pain is one of the most common musculoskeletal conditions encountered in primary care and specialty orthopedic clinic settings. Although magnetic resonance (MR) imaging is typically the modality of choice for evaluating the soft-tissue structures of the shoulder, ultrasonography (US) is becoming an important complementary imaging tool in the evaluation of superficial soft-tissue structures such as the rotator cuff, subacromial-subdeltoid bursa, and biceps tendon. The advantages of US driving its recent increased use include low cost, accessibility, and capability for real-time high-resolution imaging that enables dynamic assessment and needle guidance. As more radiologists are considering incorporating shoulder US into their practices, the development of a standardized approach to performing shoulder US should be a priority to facilitate the delivery of high-quality patient care. Familiarity with and comfort in performing a standardized shoulder US examination, as well as knowledge of the types of anomalies that can be evaluated well with US, will enhance the expertise of those working in musculoskeletal radiology practices and add value in the form of increased patient and health care provider satisfaction. This review describes the utility and benefits of shoulder US as a tool that complements MR imaging in the assessment of shoulder pain. A standardized approach to the shoulder US examination is also described, with a review of the basic technique of this examination, normal anatomy of the shoulder, common indications for shoulder US, and characteristic US findings of common shoulder diseases-with select MR imaging and arthroscopic correlation.

Abstract
BACKGROUND The incidence of asymptomatic rotator cuff tears has been reported to range from 15% to 39%, but the influence of asymptomatic rotator cuff pathology on shoulder function is not well understood. This study assessed the effects of asymptomatic rotator cuff pathology on shoulder kinematics, strength, and patient-reported outcomes. METHODS A clinical ultrasound examination was performed in 46 asymptomatic volunteers (age: 60.3 ± 7.5 years) with normal shoulder function to document the condition of their rotator cuff. The ultrasound imaging identified the participants as healthy (n = 14) or pathologic (n = 32). Shoulder motion was measured with a biplane x-ray imaging system, strength was assessed with a Biodex (Biodex Medical Systems, Inc., Shirley, NY, USA), and patient-reported outcomes were assessed using the Western Ontario Rotator Cuff Index and visual analog scale pain scores. RESULTS Compared with healthy volunteers, those with rotator cuff pathology had significantly less abduction (P = .050) and elevation (P = .041) strength, their humerus was positioned more inferiorly on the glenoid (P = .018), and the glenohumeral contact path length was longer (P = .007). No significant differences were detected in the Western Ontario Rotator Cuff Index, visual analog scale, range of motion, or acromiohumeral distance. CONCLUSIONS The differences observed between the healthy volunteers and those with asymptomatic rotator cuff pathology lend insight into the changes in joint mechanics, shoulder strength, and conventional clinical outcomes associated with the early stages of rotator cuff pathology. Furthermore, these findings suggest a plausible mechanical progression of kinematic and strength changes associated with the development of rotator cuff pathology.

Abstract
Radiography remains pivotal to the workup of instability lesions of the shoulder, both in the acute as well as the chronic settings. The goal of radiography is to detect osseous abnormalities and locate them in order to determine the direction of instability. In antero-inferior instability, Hill-Sachs lesions are often visible at radiography and should not be confused with various differential diagnoses, which are usually more laterally located. Bankart lesions are more difficult to detect on conventional radiography, but there are less false positives than for Hill-Sachs lesions. The Garth view represents an excellent radiographic view to detect antero-inferior instability impaction fractures at both the humeral and glenoid sides. Accurate quantification of bony abnormalities and detection of lesions to the soft-tissue stabilizers of the shoulder however require advanced cross-sectional imaging techniques.

Abstract
BACKGROUND Disorders of the long head of the biceps (LHB) tendon contribute to anterior shoulder pain. Although LHB tendon disorders are associated with rotator cuff disease, distinguishing between biceps and rotator cuff pathology is difficult. The objective was to identify the predictors of LHB tendon disorders associated with a supraspinatus tear. METHODS In 55 patients (average age, 65 years) undergoing arthroscopic rotator cuff repair, bicipital groove morphology were assessed using computed tomography, and subscapularis tear and bicipital groove effusion were assessed using magnetic resonance imaging, retrospectively. The LHB tendon was evaluated arthroscopically according to the Lafosse classification. Univariate and multivariate ordinal logistic regression analyses were conducted for injury grade with all covariates. RESULTS The arthroscopic evaluation of the LHB tendon showed that there were 23 shoulders classified as grade 0, 15 as grade 1, and 17 as grade 2. Univariate logistic regression analysis showed that the width and depth, a medial spur of the bicipital groove, and a subscapularis tear were significantly associated with LHB tendon disorders. Multivariate ordinal logistic regression analysis identified a medial spur and subscapularis tear as significant predictors of LHB tendon disorders. CONCLUSIONS The preoperative computed tomography and magnetic resonance images, notably the presence of a spur on the bicipital groove or a subscapularis tear, were useful for identifying LHB tendon disorders. When these are found in preoperative images, the clinician should evaluate the patient for the presence of an LHB tendon disorder as a pain generator.

Abstract
BACKGROUND AND OBJECTIVES This study aims to compare the findings of the shoulder ultrasonography (US) of patients with a supraspinatus (SS) tendon rupture with those of the shoulder arthroscopy, to determine the reliability and diagnostic performance of the shoulder US in the algorithm of the SS tendon pathologic lesions and their secondary ultrasonographic findings. DESIGN AND SETTINGS A prospective study conducted with patients scheduled for arthroscopy of the shoulder due to an SS tendon rupture in Yildirm Beyazit Education and Research Center and Gazi University, Ankara, Turkey. MATERIALS AND METHODS Fifty patients scheduled for an arthroscopy of the shoulder due to an SS tendon rupture were evaluated by shoulder US 1 week before the surgery. SS tendon pathologic lesions (tendinosis, partial tears, and full-thickness tears) and humeral degeneration were recorded, and the results of shoulder US were compared with those of arthroscopy. RESULTS With reference to the arthroscopic data, the sensitivity of the ultrasonographic evaluation for the diagnosis of a full-thickness SS tendon rupture was 91%, with a specificity of 88%; the sensitivity for the diagnosis of a partial-thickness rupture was 86%, with a specificity of 82%; and the sensitivity for the diagnosis of a tendinosis was 98%, with a specificity of 71%. With reference to the arthroscopic data, the sensitivity of US for the diagnosis of humeral degeneration was 93%, with a specificity of 91%. CONCLUSION The high sensitivity and specificity rates of US in detecting SS tendon rupture and its secondary imaging findings make it an efficient and reliable diagnostic modality, which should be preferred to other more expensive and more invasive methods in the algorithm.

Abstract
BACKGROUND Although findings of conventional radiography seem nonspecific, it is still the first imaging modality used to evaluate patients with rotator cuff tears. The purpose of this study is to determine whether the true anteroposterior (AP) view of the glenohumeral (GH) joint (the thorax is rotated to the affected shoulder for 35°-45°) is more sensitive than the conventional shoulder AP view (the beam and cassette are perpendicular to the torso but oblique to the glenohumeral joint) in terms of detecting rotator cuff tears. MATERIALS AND METHODS Intermixed GH AP and conventional AP views of 160 consecutive shoulders, which were repaired by arthroscopic surgery, were reviewed in a blinded fashion. The detection rate of 5 pathognomonic signs for rotator cuff tear were determined by use of both radiographs: greater tuberosity (GT) sclerosis, GT osteophyte, subacromial (SA) osteophyte, GT cyst, and humeral head osteophyte. An additional comparison according to the tear size was performed. RESULTS The detection of all radiographic findings was significantly greater on the GH AP view than on the conventional AP view (P < .001 for GT sclerosis, P = .003 for GT osteophyte, P = .013 for GT cyst, P < .001 for SA osteophyte, and P = .002 for humeral head osteophyte). In subgroup analysis by tear size, GT sclerosis was identified significantly more on the GH AP view for all tear sizes, GT osteophytes showed a higher detection rate, especially in medium-sized tears, and SA osteophytes showed a higher detection rate in medium and large to massive tears. CONCLUSION The GH view is more sensitive than the conventional AP view for detecting pathognomonic findings of rotator cuff tear. In particular, the superiority of the GH AP view in detecting abnormal radiographic findings seemed prominent in medium-sized tears.

Abstract
Ultrasonography is a well-established and widely accepted modality for the evaluation of rotator cuff tears and injury to the biceps brachii tendon. Ultrasonography and magnetic resonance imaging have comparable sensitivity and specificity for diagnosing both full-thickness and partial-thickness rotator cuff tears. This article addresses the ultrasonographic diagnosis of abnormalities of the rotator cuff, rotator interval, and biceps brachii, with magnetic resonance imaging and arthroscopic correlation. Characteristic ultrasonographic findings as well as imaging pitfalls are reviewed.

Abstract
The Society of Radiologists in Ultrasound convened a panel of specialists from a variety of medical disciplines to reach a consensus about the recommended imaging evaluation of painful shoulders with clinically suspected rotator cuff disease. The panel met in Chicago, Ill, on October 18 and 19, 2011, and created this consensus statement regarding the roles of radiography, ultrasonography (US), computed tomography (CT), CT arthrography, magnetic resonance (MR) imaging, and MR arthrography. The consensus panel consisted of two co-moderators, a facilitator, a statistician and health care economist, and 10 physicians who have specialty expertise in shoulder pain evaluation and/or treatment. Of the 13 physicians on the panel, nine were radiologists who were chosen to represent a broad range of skill sets in diagnostic imaging, different practice types (private and academic), and different geographical regions of the United States. Five of the radiologists routinely performed musculoskeletal US as part of their practice and four did not. There was also one representative from each of the following clinical specialties: rheumatology, physical medicine and rehabilitation, orthopedic surgery, and nonoperative sports medicine. The goal of this conference was to construct several algorithms with which to guide the imaging evaluation of suspected rotator cuff disease in patients with a native rotator cuff, patients with a repaired rotator cuff, and patients who have undergone shoulder replacement. The panel hopes that these recommendations will lead to greater uniformity in rotator cuff imaging and more cost-effective care for patients suspected of having rotator cuff abnormality.

Abstract
Ultrasound is used increasingly in the investigation of the rotator cuff. It is as accurate as magnetic resonance imaging in the detection of rotator cuff tears and the assessment of tear size and can demonstrate atrophy and fatty infiltration in the rotator cuff muscles. This article reviews the anatomy and technique of shoulder ultrasound, the ultrasound findings in rotator cuff disease, the accuracy of ultrasound and magnetic resonance imaging in the assessment of rotator cuff tears and the role of interventional ultrasound of the shoulder.

Abstract
OBJETIVO: Avaliar o ombro de nadadores em nível competitivo, sintomáticos ou não, e quantificar a incidência de lesões do manguito rotador nesses atletas. MATERIAIS E MÉTODOS: Foram estudados, por meio de exame ultra-sonográfico, ambos os ombros de 11 nadadores de nível competitivo (categoria master), sendo oito homens e três mulheres, com idade variando de 28 a 52 anos, tanto sintomáticos quanto assintomáticos, para determinação de alterações e correlação com quadro clínico. Os exames foram realizados avaliando-se os tendões que compõem o manguito rotador em pelo menos dois planos ortogonais distintos, assim como as estruturas não-tendíneas que fazem parte da articulação do ombro. As alterações tendíneas foram classificadas como tendinose, prováveis roturas intra-substanciais e roturas parciais. As lesões não-tendíneas foram classificadas como presentes ou ausentes. Além do exame, foram consideradas, na análise dos resultados, a presença ou ausência de sintomas e a idade dos pacientes. RESULTADOS: A prevalência geral de indivíduos sintomáticos foi de 63,6% (sete atletas). Neste grupo encontravam-se 75% das bursites e 100% das roturas tendíneas parciais. Entre as alterações tendíneas isoladas, o tendão mais freqüentemente acometido foi o supra-espinal, tendo alteração de seu padrão ecográfico em 36,36%. A tendinose foi o achado mais prevalente, estando presente em pelo menos um dos tendões em 50% dos ombros estudados. A incidência de roturas parciais foi semelhante à observada na população geral, sendo de 13%, estando estas, sempre que presentes, na faixa etária acima de 40 anos. CONCLUSÃO: Nadadores não parecem ter maior incidência de roturas ou degenerações tendíneas quando comparados com indivíduos da população geral. A idade dos indivíduos, sendo estes praticantes ou não de atividades que exijam sobrecarga desta articulação, é o fator com maior determinância em relação às lesões do manguito rotador.

Abstract
PURPOSE To retrospectively determine the frequency of posterior and anterior cystic abnormalities at rotator cuff insertion site on the greater tuberosity and to determine their relationship to patient age and rotator cuff disorders. MATERIALS AND METHODS Institutional review board approval was given; informed consent was waived. The study was HIPAA compliant. In 238 patients with rotator cuff diagnoses at surgery, preoperative magnetic resonance (MR) imaging studies were reviewed to localize osseous cystic changes as anterior (supraspinatus insertion site) or posterior (infraspinatus insertion site) on the greater tuberosity. If rotator cuff tear was present, tendon retraction and location of partial tear (articular or bursal surface) were recorded. Two radiologists reached conclusions by consensus. Locations of cysts were correlated to surgical cuff diagnoses: no tear, tendinopathy, partial-thickness tear, and complete tear. Prospective interpretations from original MR reports were compared with surgical results. Statistical analyses included one-way analysis of variance, chi(2), Fisher exact, and Student t tests, as well as logistic regression and receiver operating characteristic curve comparison. RESULTS There were 238 consecutive patients (150 men, 88 women; mean age, 43 years). Cysts were located at or near footprint of cuff tendon and demonstrated fluid or soft-tissue signal intensities. Posterior cysts occurred in 56.7% of shoulders and showed no statistical correlation to age or cuff diagnosis. Anterior cysts occurred in 22.7% of shoulders and were strongly associated with cuff disorders (P<.001). Controlling for cuff disorders, there was no relationship between anterior cysts and age (P>.50). Anterior cysts were more common in partial-thickness articular (48%) than in bursal (13%) tears (P<.001). CONCLUSION Posterior cysts were more common than anterior cysts and showed nearly random distribution among patients, regardless of age and cuff diagnosis. Anterior cysts were closely associated with cuff disorders.

Abstract
Radiology allows to define etiologies of tendon injuries and authorize a most suitable treatment. For that reason, the use of the sonography has been developed from several years and has four main purposes to define the type of injury and to orient the treatment: to confirm the real existence of the tendon tear, to need the exact location the same one, to determine the gravity of the lesion, and finally, to evaluate its acute or chronic character. In this paper, we will try to define the normal pattern of the tendon and describe the more frequent lesions of the shoulder or the ankle: complete or partial tear, tendinopathy, dislocation and enthesopathy.

Abstract
With recent advances in computer technology and equipment miniaturization, the clinical application of diagnostic ultrasonography (U/S) has spread across various medical specialties. Diagnostic U/S is attractive in terms of its noninvasiveness, lack of radiation, readiness of use, cost-effectiveness, and its ability to make dynamic examinations possible. Dynamic imaging deserves special emphasis because it is useful in differentiating full-thickness from partial-thickness tendon tears, muscle tears, and tendon and nerve subluxations or dislocations. It is also a quick and easy avenue for side-to-side comparisons. When appropriately used, diagnostic U/S can be considered as an extension of one's physical examination. However, there are limitations of U/S, which will be discussed in this review article. This is part 1 of two articles; this first part will focus on the ultrasound examination of the upper extremity, using selected examples relevant to musculoskeletal medicine. Part 2 will cover common pathologies of the lower extremity.

Abstract
OBJECTIVE To evaluate the radiographic and clinical outcome, including the incidence of recurrence, in patients with displaced greater tuberosity (GT) fractures associated with a traumatic anterior shoulder dislocation. DESIGN Retrospective study. SETTING University Hospital (Level 1 trauma center). PATIENTS There were 34 completely evaluated patients (19 male, 15 female) seen between 1993 and 2002 with a displaced GT fracture associated with a traumatic anterior shoulder dislocation. Average age was 52.8 years and the mean follow-up period was 4.8 years (range, 2.0 to 10 years). INTERVENTION All GT fractures were internally fixed solely with heavy non-absorbable sutures and any associate rotator cuff tear was repaired at the same time. A special rehabilitation protocol was administered in all patients. MAIN OUTCOME MEASUREMENTS Functional assessment was obtained using the parameters of the Constant score which grades outcomes as excellent, very good, good and poor. RESULTS Overall, there were 25 (73.5%) excellent, 6 (17.6%) very good, 2 (5.8%) good and 1 (3.1%) poor results, and the average Constant score was 88.4 (range 45.0 to 100.0). All fractures healed radiographically, without evidence of secondary displacement, except in one patient. No case of recurrence of dislocation was noted in any patient. Partial absorption or "lysis" of the GT without significant clinical relevance was detected in 4 cases. CONCLUSIONS Displaced fractures of the GT after traumatic anterior shoulder dislocation may result in limitation of motion and functional disability if they are not treated promptly by surgery. Open reduction and stable fixation of the GT along with rotator cuff repair when present, allows for early passive motion of the joint, and yields excellent final results in approximately three quarters of the patients and restores their ability to return to full activities of daily living. A compliant patient is also necessary for a successful result.

Abstract
The two major imaging modalities used for assessment of soft tissue injuries are ultrasound and MRI. Although ultrasound of the extremities is used only to a limited extent in the United States, it is widely used in many other countries for evaluation of extremity injuries. This article first considers the advantages and disadvantages of MRI and ultrasound. Understanding these differences will help the reader understand the role of ultrasound as compared with MRI in evaluating upper extremity injuries. The uses of ultrasound for evaluating sports medicine injuries in specific regions of the upper extremity are then reviewed. Where the data are available, the reported accuracy of ultrasound is compared with MRI for each type of injury.

Abstract
In the recent years there has been an increase in the number of tendon tears (TT) seen in routine daily outpatient practice secondary to the increasing popularity of sport activities. Tears require early diagnosis to ensure proper treatment and reduce functional impairment. Since local pain, edema and reflex muscle contraction can significantly limit the usefulness of clinical examination, imaging is usually required to confirm the clinical diagnosis, differentiate between partial and complete tear, and localize the retracted tendon stump. Several imaging modalities can be used in the evaluation of TT. Ultrasound is an efficient, dynamic, low cost and non invasive modality that is being increasingly utilized in the evaluation of the musculoskeletal system. It is well accepted by the acutely injured patient. The aim of this review article is to describe the ultrasound findings of the most common tendon tears.

Abstract
The role of ultrasound (US) in assessing musculoskeletal disorders is persistently increasing because of its low cost, readiness, noninvasiveness, and possibility of allowing a dynamic examination. Secondary to increased sport practice, tendon tears are more frequently observed in daily medical practice. They deserve early diagnosis to allow proper treatment that can limit functional impairment. The aim of this review article is twofold: to illustrate the US appearance of normal tendons and to describe the US findings of the most common tendon tears.

Abstract
PURPOSE To determine which US signs are important in the diagnosis of a surgically identifiable supraspinatus tendon tear. MATERIALS AND METHODS Fifty consecutive ultrasonographic (US) studies of the shoulder in patients who underwent arthroscopic follow-up were retrospectively reviewed by a musculoskeletal radiologist. US images of the supraspinatus tendon were evaluated for tendon nonvisualization, abnormal tendon echogenicity, tendon thinning, greater tuberosity cortical irregularity, cartilage interface sign, joint fluid, and subacromial-subdeltoid bursal fluid. US findings were compared with arthroscopic results. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated for each US sign in the diagnosis of full-thickness tendon tear and again for any type of supraspinatus tendon tear. RESULTS Arthroscopy revealed 21 full-thickness tears, five bursal surface partial-thickness tears, 10 articular surface partial-thickness tears, and 14 patients without tear of the supraspinatus tendon. The presence of greater tuberosity cortical irregularity and joint fluid was most important in the diagnosis of full-thickness supraspinatus tendon tear (sensitivity, 60%; specificity, 100%; positive predictive value, 100%; negative predictive value, 78%; accuracy, 84%). For diagnosis of any type of supraspinatus tendon tear (partial or full thickness), tendon nonvisualization, greater tuberosity cortical irregularity, and cartilage interface sign are most important, although a combination of signs did not improve accuracy. CONCLUSION Secondary US signs, such as greater tuberosity cortical irregularity and joint fluid, are most valuable in the diagnosis of supraspinatus tendon tear.

Abstract
This study compared shoulder radiographs of patients with a documented rotator cuff tear with those of asymptomatic age-matched controls. Radiographs of 40 subjects with documented rotator cuff tears were evaluated along with similar films of 84 asymptomatic age-matched controls. Three radiographs were taken of each shoulder: (1) acromioclavicular joint view, (2) anterior-posterior view with 30 degrees of external rotation, and (3) supraspinatus outlet view. Two fellowship-trained radiologists interpreted 14 radiographic areas in a blinded fashion. Inspection of the greater tuberosity showed large positive abnormal ratings for sclerosis, osteophytes, subchondral cysts, and osteolysis. No association was noted between acromial morphology and rotator cuff tears. These results indicate that shoulder radiographs of subjects with a documented rotator cuff tear have greater tuberosity radiographic abnormalities that are not noted in asymptomatic subjects without a rotator cuff tear. No relationship was found between tear length and any of the degenerative conditions.

Abstract
Musculoskeletal sonography has been shown to be effective for many applications related to sports medicine. Some advantages of sonography over MR imaging include portability, accessibility, high resolution, and relative lower cost. More importantly, dynamic imaging under sonography visualization allows diagnoses that cannot be made with routine MR imaging. Additionally, direct imaging correlation with patient symptoms provides important information to the referring clinicians. The disadvantages of sonography include operator dependence and long learning curve. This can be minimized, however, with proper training and standardized technique. Musculoskeletal sonography has proved itself as one of several imaging methods invaluable to the diagnosis of sport medicine-related abnormalities.

Abstract
We examined the location of rotator cuff tears, associated labral injuries, and notches on the greater tuberosity of the humeral head in shoulders of throwing athletes. Arthroscopic findings (rotator cuff tear, labral condition, and greater tuberosity notch) as well as other factors (duration of playing baseball, range of motion, and joint laxity) of 61 baseball players were retrospectively studied. The presence of a greater tuberosity notch was also evaluated for by plain radiographs. Forty patients had articular-side partial rotator cuff tears, most of which occurred in the interval between the supraspinatus and infraspinatus tendons. The existence of a rotator cuff tear was not related to the range of motion, joint laxity, the detachment of the superior glenoid labrum, or posterosuperior labral injury. Greater tuberosity notches were recognized in 38 shoulders by arthroscopy and most were detected on plain radiographs. The presence of a notch was significantly related to the existence of a rotator cuff tear, while the size of the notch was significantly related to the depth and width of the tear. The greater tuberosity notch seems to be one of the most important diagnostic indicators for a rotator cuff tear in throwing athletes.

Abstract
The purpose of this study was to identify early signs of rotator cuff tear and glenohumeral articular cartilage degeneration by using conventional radiography. A non-weighted anteroposterior oblique and a weighted active abduction view were evaluated for superior humeral migration and matching degenerative changes at the inferolateral acromion and superior aspect of the greater tuberosity in 40 patients who underwent shoulder arthroscopy. Measurements of the glenohumeral distance were performed. Surgical reports were reviewed to determine rotator cuff and glenohumeral articular cartilage status. Matching degenerative changes correlate with complete rotator cuff tear (P =.04); superior migration does not. Severe glenohumeral cartilage loss correlates with narrowing of the superior joint space on the anteroposterior oblique radiograph (P =.02) and with narrowing of the mid joint space on the active abduction view (P =.05). Both glenohumeral articular cartilage degenerative change and rotator cuff injury, before formation of typical sequelae of chronic rotator cuff tear, can be detected with the use of conventional radiography.

Abstract
Musculoskeletal ultrasound (MSUS) is an important modality in evaluating shoulder disease. Following a baseline shoulder conventional radiographic examination, MSUS can be used to screen the painful shoulder. It is accurate in diagnosing full- and partial-thickness tears of the rotator cuff. Both types of tears can be further characterized by size, location, and extension. Postoperatively, the rotator cuff can also be evaluated for recurrent full-thickness tears. MSUS is the only modality that can visualize and characterize synovial disease, without radiographic contrast, and when necessary, US-guided aspiration and biopsy can be performed. Real-time scanning shows the actual motion of the shoulder and its parts. Multiple attempts can be made to achieve optimal images for accurate documentation. Accessibility to MSUS facilitates the rapid turnaround of patients. US imagers and bone radiologists would do well to use MSUS to help their referring physicians establish a quick and accurate diagnosis of shoulder disorders. This article presents a comprehensive, pictorial review of the technical aspects of shoulder sonography as well as major types of pathology that can be diagnosed with US.

Abstract
Since the mid 1980s, sonography has been used to evaluate the rotator cuff. It is inexpensive, well tolerated, rapidly performed, and accurate. With the recent improvements in imaging equipment and refinements in scanning technique, an increasing number of radiologists are performing shoulder sonography. This article emphasizes the pertinent musculoskeletal anatomy, sonographic technique, normal sonographic anatomy, pathophysiology of rotator cuff and biceps tendon disease, sonographic findings of rotator cuff tears, and biceps tendon pathology. The accuracy of ultrasound in diagnosing rotator cuff tears and miscellaneous abnormalities that can be detected with ultrasound also are discussed.

Abstract
To successfully examine the musculoskeletal system sonographically, one must understand the normal musculoskeletal anatomy and function and be aware of the abnormal processes that affect the musculoskeletal structures. The goal of this review article is to provide a systematic approach to sonographic examination of the musculoskeletal system. The general sonographic appearances of normal and abnormal muscles, tendons, ligaments, bursae, and nerves are reviewed. The article then applies this general information to specific clinical applications by reviewing the normal anatomy of and specific pathologic conditions that affect the shoulder, elbow, hand, wrist, hip, knee, ankle, and foot.
