Abstract
INTRODUCTION Shoulder ultrasonography is revised in the evaluation of complete rotator cuff tears. Also another technique known as artro-ultrasonography, which consist of a 10 mL solution injection inside the articular capsule to observe its escape to the subacromial-subdeltoidea bursae which implicates rotator cuff tear. It is compared against multiple standards like surgery, magnetic resonance, arthrography and rehabilitation to include positive and negative cases. MATERIAL AND METHODS 181 consecutive cases were studied with ultrasonography, 27 with artro-ultrasonography. The criteria for tear is the absence of the hyper-ecogenicity in the tendon, hypo-ecogenic gaps inside the rotator cuff and distention of the bursae due to the presence of liquid. RESULTS 69% sensibility and 71% specificity for ultrasonography. 92% sensibility and specificity for artro-ultrasonography. The area under the COR curve is 70% for ultrasonography and 93% for artro-ultrasonography. The artro-ultrasonography modified the diagnosis in nine cases, the majority from normal to tear. Three Radiologists proved the agreement with good results. DISCUSSION The study contributes to evaluate the performance of ultrasound against multiple standards to correct the great variability in results observed in literature. The contribution of artro-ultrasonography to diagnosis is evaluated. It can be useful in places where accuracy is important and more sophisticated methods like magnetic resonance are not available.

Abstract
INTRODUCTION Arthroscopic repair of the rotator cuff have shown have shown encouraging clinical results. However, few authors have assessed integrity of repair with ultrasound. The presence of re-rupture by ultrasonography in a rotator cuff repair may not relate to the patient's functional status. OBJECTIVE We used ultrasonography to assess the prevalence of re-rupture in rotator cuff repairs and its clinical relevance with minimum 1 year postoperatively. MATERIALS AND METHODS Evidence level IV (Case series). We evaluated 27 shoulders that underwent arthroscopic rotator cuff repair. Clinical evaluation was performed using UCLA functional scale, visual analogue scale (UCLA, VAS). Post-operative ultrasound was performed at least 1 year postoperatively. Statistical analysis was done with the SPSS 11.0 software. RESULTS We examined 27 shoulders, mean age 56.4 (41-78), mean postoperative follow-up 19.6 (12 m-88 m). Clinical assessment with UCLA functional scale results were: good-excellent (77.4%); fair (22.2%). VAS results showed that 44.4% reported VAS of 0; in the range of 1-3 VAS was 55.5% of the patients. Ultrasound evaluation showed no injury in 37%; partial lesion 51.9%, and a total lesion 11.1%. Thirty-three % of the patients with VAS of 0 showed no injury when evaluated by ultrasonography, injury by ultrasound 33.3% with VAS (1-3) 22.2%. UCLA (good-excellent) without injury by ultrasound 33.3% with a 44.4% degree of injury, UCLA (Fair) without injury 3.7%, with some degree of lesion 18.5%. Results no statistically significant difference (p > 0.05). CONCLUSIONS In our series, we find that integrity of rotator cuff postoperative ultrasound, it has no effect on the functional status of patients with postoperative follow-up of at least 1 year, with UCLA and VAS.

Abstract
Results of arthroscopic management of chronic, recalcitrant calcific tendinopathy of the shoulder in 28 patients were evaluated. Twenty-six patients (average age, 44 years) were ultimately enrolled in the study. Postoperative radiographs were performed to determine the amount of calcium deposit removal. Radiographic examination 2 months after surgery was performed to evaluate further deposit changes. The Constant score showed a statistically significant improvement in all patients. Better results were obtained when complete removal of the calcifications was achieved. On radiographic examination, performed two months after surgery, no calcification deposit increased in size and no translucent deposit changed into a dense deposit. Most of the dense deposits, partially removed, changed into translucent deposits. In this series, we found arthroscopic management was effective in treating calcific tendinopathy.

Abstract
INTRODUCTION The aim of this study was to evaluate whether aspiration affects patient outcome during ultrasound-guided needle puncture treatment for calcifying supraspinatus tendinitis. METHODS Eighty-one patients with calcifying supraspinatus tendinitis received needle puncture therapy under ultrasonography guidance. Group A received ultrasound-guided percutaneous needle punctures and aspiration of calcareous deposits, while Group B received ultrasound-guided punctures only. Patients were evaluated using a visual analog scale (VAS) for pain, shoulder function, and satisfaction 1, 2, 3, 6, 12, 24, and 36 weeks after treatment. The different VAS parameters were combined and the differences between groups were analyzed. RESULTS In both groups, VAS scores significantly decreased over the 36 weeks following treatment (P<0.05). Overall, the majority (6/7) of the VAS scores were not statistically different between groups. CONCLUSION The results of the study suggest that aspirating calcified deposits do not affect patient outcome. Puncturing the calcified deposits (without aspiration) appears to be an effective treatment method for calcifying supraspinatus tendinitis.

Abstract
The rotator interval corresponds to a defined triangular shaped anatomical region at the anterosuperior portion of the shoulder where specific pathological processes may occur. First, the morphological and functional anatomy of the region will be reviewed. Then, the role of different imaging modalities will be described along with pathological imaging features. Normal structures of the rotator interval may be imaged with modern techniques, including MR and CT arthrography. On the other hand, clinical evaluation of rotator interval pathology remains difficult; and no consensus exists concerning their management. Imaging characterization of rotator interval pathology could be a key factor for pre-therapeutic work-up.

Abstract
BACKGROUND We have introduced a one-stop clinic for the diagnosis and management of rotator cuff tears (RCTs). The aim of the study was to determine the effect of the one-stop clinic on the interval and delay in management for patients with suspected rotator cuff pathology. PATIENTS AND METHODS Seventy-four patients were reviewed retrospectively; 39 had an ultrasound of the shoulder before (group 1), and 35 patients after (group 2) the new protocol was introduced. Patients in group 2 had a shoulder ultrasound scan (USS) on the day of their clinic appointment or beforehand based upon the General Practitioners (GP) letter. Indications included patients over the age of 30, or patients with a history of trauma or a painful shoulder. RESULTS Twenty-four patients were diagnosed with RCTs on USS with an overall sensitivity of 93.75%, specificity 100% and accuracy of 91% for full thickness tears. Clinical detection alone had an overall sensitivity of 80%, a specificity of 91% and accuracy of 87%. Mean time from GP referral to definitive management plan was 6.49 months (SD 2.74) in group 1, compared with 4.63 months (SD 1.43) in group 2 with an overall reduction in half the number of clinic appointments. This was statistically significant (p < 0.001). CONCLUSIONS Ultrasound scan of the shoulder is an accurate and reliable method of detecting full thickness RCTs. The one-stop clinic significantly shortened the interval between GP referral and definitive management.

Abstract
BACKGROUND Rotator cuff tear--diagnosis; comparison of MRI, ultrasonographic and arthroscopic findings. MATERIALS AND METHODS Retrospective study--20 patients treated for shoulder pain due to rotator cuff tear, initially conservatively and after more than 6 months by arthroscopic shoulder surgery. Comparison of intraoperative findings with preoperative US and MRI images. RESULTS Sensitivity of USG--1.0, specificity 0.9. Sensitivity of MRI--0.92, specificity 1.0. DISCUSSION Clinical examination and physical tests are not fully reliable diagnostic tools in patients with shoulder pain, because symptoms of different conditions overlap. Using ultrasound to visualize the shoulder area has some advantages to other imaging techniques such as CT scan or MRI, and has a very good sensitivity and good specificity. Many authors agree that MRI is one of the most effective methods for the diagnosis of rotator cuff tear. CONCLUSIONS Ultrasound and magnetic resonance imaging are both very sensitive techniques for diagnosis of rotator cuff abnormalities. Ultrasonography can be used as a primary method owing to its fast procedure and affordable cost.<br />

Abstract
Rotator cuff tears are a common injury that affect a significant percentage of the population over age 60. Although it is widely believed that the rotator cuff's primary function is to stabilize the humerus against the glenoid during shoulder motion, accurately measuring the three-dimensional (3D) motion of the shoulder's glenohumeral joint under in-vivo conditions has been a challenging endeavor. In particular, conventional motion measurement techniques have frequently been limited to static or two-dimensional (2D) analyses, and have suffered from limited or unknown in-vivo accuracy. We have recently developed and validated a new model-based tracking technique that is capable of accurately measuring the 3D position and orientation of the scapula and humerus from biplane X-ray images. Herein we demonstrate the in-vivo application of this technique for accurately measuring glenohumeral joint translations during shoulder motion in the repaired and contralateral shoulders of patients following rotator cuff repair. Five male subjects were tested at 3-4 months following arthroscopic rotator cuff repair. Superior-inferior humeral translation was measured during elevation, and anterior-posterior humeral translation was measured during external rotation in both the repaired and contralateral shoulders. The data failed to detect statistically significant differences between the repaired and contralateral shoulders in superior-inferior translation (p=0.74) or anterior-posterior translation (p=0.77). The measurement technique overcomes the limitations of conventional motion measurement techniques by providing accurate, 3D, in-vivo measures of glenohumeral joint motion during dynamic activities. On-going research is using this technique to assess the effects of conservative and surgical treatment of rotator cuff tears.

Abstract
Diagnosing shoulder pathology accurately requires both clinical expertise and the ability to interpret and correlate radiographic studies. Variational anatomy of the shoulder combined with the complexity of physical examination makes this difficult. Physical examination of the shoulder often leaves the surgeon with more than one working diagnosis. Imaging studies of the shoulder are more valuable if used to confirm a working diagnosis as opposed to reading the study in a vacuum. Clinical correlation should also be considered for any and all findings on an imaging study. Collaboration of the surgeon and the radiologist is essential in reducing the number of over-reported findings that are clinically insignificant. The surgeon should directly communicate with the radiologist as to his or her working diagnosis and the goal of the study. In this way the surgeon and radiologist become superior diagnosticians.

Abstract
Surface replacement arthroplasty of the shoulder offers the ability to restore anatomy and biomechanics of the glenohumeral joint, if sufficient humeral bone stock of at least 60% of the humeral head is preserved and no severe deformity is present. The implantation following the individual anatomy helps to avoid complications such as prosthetic malpositioning and periprosthetic fractures. While the use of a glenoid component is technically demanding, revision to a stem prosthesis is relatively easy because of bone stock preservation. Indications for humeral head resurfacing are osteoarthritis (OA), rheumatoid arthritis (RA), avascular necrosis stages 2-4, and stable forms of cuff tear arthropathy (CTA). Published results for OA and RA are comparable to those obtained with modern modular stem prostheses; the use in CTA appears promising under "limited goals criteria."

Abstract
The treatment of cuff tear arthropathy (CTA) of the shoulder is based on the patient's subjective complaints, functional deficits, and the treatment goals that result from both. Only in the second line is the radiologic morphology of joint destruction important for the surgeon's decision. Based on these aspects it is possible to discriminate three types of CTA that obviously have similar functional deficits and radiological characteristics. This symptom-based classification can offer decision guidelines for the choice of an appropriate joint replacement.For the most frequent, stable, and osteoarthritic type with pain during motion and a tolerably restricted active and passive range of motion (ROM) surface replacement or hemiarthroplasty can lead to reasonable results. In the unstable type with only minimal radiological changes of the humeral head and the chief complaint of severe restriction of active ROM and in some cases recurrent shoulder dislocations, hemiarthroplasty with a glenoid reconstruction shell or reversed prosthesis are promising. A reverse prosthesis is the implant of choice for the necrotic type of CTA with extensive destruction of the humeral head, the glenoid, and the adjacent bony structures.

Abstract
Ultrasound has been widely used for the evaluation of the shoulder, mainly for rotator cuff pathology. Developments in technology, as well as better knowledge of the pathology and the anatomy make this examination one of the most useful in the exploration of the shoulder, especially in the hands of the experienced radiologist. Ultrasound is low-cost, readily available and should be considered with plain films as the first step examination of the shoulder. Ultrasound is not only useful for the evaluation of the rotator cuff pathology and impingement syndrome, but is also performing in the evaluation of non rotator cuff pathology such as biceps tendon pathology, shoulder instability, mass evaluation, infection, degenerative and inflammatory arthropathies and nerve entrapment syndromes. Making a complete evaluation of the shoulder helps to differentiate between rotator cuff pathology and others that can mimic rotator cuff disorders. This article will review shoulder anatomy and examination technique and the different pathologies that can be assessed by ultrasound.

Abstract
PURPOSE To re-evaluate the relationship between os acromiale and rotator cuff tears. METHODS We retrospectively analyzed 84 magnetic resonance imaging studies of the shoulder. Forty-two subjects with os acromiale (n = 42; 32 men and ten women, age 25-81 years, mean 47.6 years) were compared with age- and gender-matched subjects with no evidence of os acromiale (controls). Arthroscopy data were available in 19 os acromiale and 12 control subjects. Statistical analyses were performed to determine differences between groups regarding rotator cuff tears affecting the supraspinatus and infraspinatus tendons detected by magnetic resonance imaging and arthroscopy. Analysis of os acromiale type, ossicle synchondrosis edema, acromioclavicular joint degenerative changes and step-off deformity at the synchondrosis were tabulated. RESULTS No statistically significant difference between the os acromiale and control groups was noted, either on magnetic resonance imaging or arthroscopy, with regard to tears of the supraspinatus (P = 1.000 and 0.981, respectively) and infraspinatus (P = 1.000 and 0.667, respectively) tendons. There was a statistically significant increased number of supraspinatus (P = 0.007) and infraspinatus (P = 0.03) tears in a comparison of subjects with os acromiale and step-off deformity (10/42) vs os acromiale without step-off deformity (32/42). CONCLUSION The presence of os acromiale may not significantly predispose to supraspinatus and infraspinatus tendon tears. However, subjects with step-off deformity of an os acromiale are at greater risk of rotator cuff tears than are similar subjects without such deformity.

Abstract
BACKGROUND The shoulder's subacromial space is of significant clinical interest due to its association with rotator cuff disease. Previous studies have estimated the subacromial space width to be 2-17 mm, but no study has measured in vivo subacromial space width during shoulder motion. The purpose of this study was to measure the in vivo subacromial space width during shoulder elevation in patients following rotator cuff repair. METHODS Biplane X-ray images were collected during shoulder elevation of 11 patients who had undergone rotator cuff repair. Glenohumeral joint motion was measured from the biplane X-ray images for each subject's repaired and asymptomatic, contralateral shoulders. The joint motion data were combined with subject-specific CT models to measure the subacromial space width during shoulder motion. FINDINGS Subacromial space width decreased with shoulder elevation, ranging from 2.3 to 7.4 mm in the repaired shoulder and 1.2-7.1 mm in the contralateral shoulder. Subacromial space width in the repaired shoulder was only 0.5 mm less than the contralateral shoulder when averaged over 10-60 degrees of glenohumeral elevation. INTERPRETATION The results indicate that the humerus in the repaired shoulder is positioned more cranially on the glenoid than in the contralateral shoulder. It is unclear if these subtle differences in subacromial space width are due to the surgical procedure or post-operative stiffness, or if subacromial impingement contributed to the development of the rotator cuff tear. Future research will ascertain if these results represent a transient response to the surgery or a more fundamental difference in rotator cuff function between repaired and contralateral shoulders.

Abstract
The objectives of this study were: 1) to identify the ultrasonographic (US) abnormalities and 2) to compare the findings of physical examination with US findings in rheumatoid arthritis (RA) patients with shoulder pain. We studied 30 RA patients. Physical examination was performed systemically as follows: 1) area of tenderness; 2) range of passive and active shoulder motion; 3) impingement tests; 4) maneuvers for determining the location of the tendon lesions. US investigations included the biceps, the supraspinatus, infraspinatus, and subscapularis tendons; the subacromial-subdeltoid bursa; and the glenohumeral and acromioclavicular joints. Thirty RA patients with 35 painful and 25 non-painful shoulders were examined. The range of motion affected the most by shoulder pain was abduction. The most frequent US finding of shoulder joint was effusion in the long head of the biceps tendon. Among the rotator cuff tendons, subscapularis was the most frequently involved. Tendon tear was also common among non-painful shoulders. Physical examination used for the diagnosis of shoulder pain had low sensitivity and specificity for detecting abnormalities in the rheumatoid shoulder joint. In conclusion, US abnormalities showed frequent tendon tears in our RA patients. Physical examination had low sensitivity and specificity for detecting rotator cuff tear in the rheumatoid shoulder joint.

Abstract
Posterior or lateral dislocation of the long head of biceps is a rare complication of shoulder dislocation that can result in inability to relocate the humerus. The diagnosis should be suspected when certain radiographic features are present at the initial presentation. Other imaging modalities can aid diagnosis when clinical management is unsuccessful or protracted. We present a case of surgically proven posterior dislocation of the biceps tendon with conventional radiographic, computed tomography and magnetic resonance imaging assessment. The literature on this subject is reviewed, and imaging features associated with the diagnosis are described.

Abstract
BACKGROUND Prevalence of rotator cuff tears increases with advancing age. Despite proximal humeral fractures being common in the elderly, the influence of a coexistent rotator cuff tear on outcome has, to our knowledge, not been previously investigated. This study prospectively assessed whether the presence of a rotator cuff tear in association with a proximal humeral fracture influences functional prognosis. METHODS Eighty-five patients treated conservatively for proximal humeral fractures were evaluated prospectively with ultrasonography to determine the status of the rotator cuff. Every patient was managed by immobilization in an arm sling for 2 weeks followed by physiotherapy. Functional outcome was measured using the Constant and the Oxford shoulder score, at 3 and 12 months postinjury. RESULTS There were 43 patients with full-thickness cuff tears and 42 patients with no cuff tear or a partial-thickness tear. Full thickness cuff tears were more frequent in patients more than 60 years old. The outcome scores at 3 and 12 months showed no statistically significant difference for either the Constant or the Oxford shoulder score with regard to cuff integrity. Analysis of these scores showed no correlation between presence or absence of a full-thickness cuff tear and shoulder function. CONCLUSION The results indicate that rotator cuff integrity is not a predictor of shoulder function at 12 months after proximal humeral fracture, as measured by outcome scores and therefore there is no clinical indication for routine imaging of the rotator cuff in patients for whom conservative management is the preferred treatment option.

A total of 120 patients with shoulder pain were prospectively studied. The physical examination of shoulders was performed as follows: (1) the area of tenderness; (2) the range of passive and active motion for abduction, forward flexion, external rotation, and internal rotation; (3) Neer and Hawkins's tests for shoulder impingement; and (4) maneuvers for determining the location of the tendon lesions. Transverse and longitudinal planes from the long head of the biceps, supraspinatus, infraspinatus, and subscapularis tendons, the subacromial-subdeltoid bursa, and the glenohumeral and acromioclavicular joints were included for US examination. The range of motion most affected by shoulder pain was abduction, followed by external rotation and forward flexion. The most frequent US finding was effusion in the long head of the biceps tendon. Among the rotator cuff tendons, supraspinatus was the most frequently involved. Physical examination had low sensitivity and specificity for the detection of tendon tear. US examination leads to an anatomical diagnosis of shoulder pain in many patients. Whether the US examination of the painful shoulder improves its treatment should be investigated.

Abstract
Both diagnostic ultrasound and magnetic resonance imaging (MRI) are used for investigation of the presence and severity of rotator cuff lesions. There is no consensus as to which is the more accurate and cost-effective study. We sought to examine the sensitivity of ultrasound, when used by one experienced radiologist with modern equipment. We compared the ultrasound and surgical results obtained from 68 patients. Ultrasound showed a sensitivity of 89% and specificity of 100% (Positive Predictive Value 100%) for full-thickness tears, and a sensitivity of 79% and specificity of 94% (Positive Predictive Value 87%) for partial-thickness tears. We found that shoulder ultrasound, in the hands of an experienced radiologist with the use of modern high-resolution equipment, is highly sensitive in differentiating complete tears and partial-thickness tears. Our results are similar to the best published results for MRI and given that ultrasound is significantly cheaper and more available, ultrasound by an experienced radiologist should be considered as a primary diagnostic tool for imaging the rotator cuff.

Abstract
BACKGROUND The treatment of rotator cuff tears has evolved from open surgical repairs to complete arthroscopic repairs over the past two decades. In this study, we reviewed the results of arthroscopic rotator cuff repairs with the so-called double-row, or footprint, reconstruction technique. METHODS Between 1998 and 2002, 264 patients underwent an arthroscopic rotator cuff repair with double-row fixation. The average age at the time of the operation was fifty-nine years. Two hundred and thirty-eight patients (242 shoulders) were available for follow-up; 210 were evaluated with a full clinical examination and thirty-two, with a questionnaire only. Preoperative and postoperative examinations consisted of determination of a Constant score and a visual analogue score for pain as well as a full physical examination of the shoulder. Ultrasonography was done at a minimum of twelve months postoperatively to assess the integrity of the cuff. RESULTS The average score for pain improved from 7.4 points (range, 3 to 10 points) preoperatively to 0.7 point (range, 0 to 3 points) postoperatively. The subjective outcome was excellent or good in 220 (90.9%) of the 242 shoulders. The average increase in the Constant score after the operation was 25.4 points (range, 0 to 57 points). Ultrasonography demonstrated an intact rotator cuff in 83% (174) of the shoulders overall, 47% (fifteen) of the thirty-two with a repair of a massive tear, 78% (thirty-two) of the forty-one with a repair of a large tear, 93% (113) of the 121 with a repair of a medium tear, and 88% (fourteen) of the sixteen with a repair of a small tear. Strength and active elevation increased significantly more in the group with an intact repair at the time of follow-up than in the group with a failed repair; however, there was no difference in the pain scores. CONCLUSIONS Arthroscopic rotator cuff repair with double-row fixation can achieve a high percentage of excellent subjective and objective results. Integrity of the repair can be expected in the majority of shoulders treated for a large, medium, or small tear, and the strength and range of motion provided by an intact repair are significantly better than those following a failed repair. LEVEL OF EVIDENCE Therapeutic Level IV.

Abstract
The purpose of our study was to correlate radiographic characteristics with rotator cuff tendon injury on magnetic resonance imaging after fractures of the proximal humerus. We prospectively obtained magnetic resonance imaging on 30 patients with proximal humerus fractures after classifying each fracture radiographically using Neer and AO systems and determining the displacement of the greater tuberosity. Twelve patients (40.0%) had either complete ruptures or avulsions of at least one of the rotator cuff muscles. No abnormality was identified in the rotator cuff musculature in nine patients (29%). Severity of injury to the rotator cuff tendons increased substantially with respect to increasing AO and Neer classes and 5 mm or greater displacement of the greater tuberosity fragment. Additional study is needed to determine the exact role of rotator cuff tendon injury in the ultimate function attained by patients with proximal humerus fractures.

Abstract
PURPOSE OF THE STUDY The goal of this study was to assess the clinical and radiological outcome of bipolar shoulder prosthesis in twelve shoulders with rheumatoid arthritis (RA) and irreparable rotator cuff tears. MATERIAL AND METHODS The follow-up was more than five years (range 2-9 years). In addition, in order to investigate the effect of rheumatoid arthritis on outcome, results were compared with ten bipolar shoulder prostheses implanted for osteoarthritis with massive rotator cuff tears. RESULTS The mean preoperative Constant score was 16.9 points with 2.6 points for pain, 4.2 points for activity, 9.5 points for motion and 0.6 points for force. The preoperative active motion was 63.8 degrees for forward flexion, 45 degrees for abduction and 12 degrees for active external rotation. At last follow-up, the average Constant score was 39.4 points with 10.7 points for pain, 10.8 points for activity, 13.8 points for motion and 4.1 points for force. Regarding the active motion, mean forward flexion was 83.7 degrees, 70.4 degrees for abduction and 29.1 degrees for external rotation. The complication rate was low, mainly superior migration due to infraspinatus tear and glenoid wear. Satisfactory deltoid arm level was achieved in all patients and no loosening was observed. Preoperative and postoperative scores of the rheumatoid group were not significantly different from the arthritis group (p<0.001). DISCUSSION Our findings suggest that bipolar shoulder prosthesis provides a viable replacement alternative in RA combined with massive rotator cuff tear with a low rate of complication. Bipolar shoulder prosthesis demonstrates no clear superiority over conventional hemiarthroplasty regarding improved motion and glenoid wear. In addition, no significant difference with arthritis was observed (p<0.05), assuming that outcome depends principally on the preoperative condition of the rotator cuff. CONCLUSION Some massive tears involving the subscapularis tendon can lead to anterior recurrence after bipolar shoulder prosthesis. They might be a limit to the procedure and require a reversed shoulder prosthesis or a glenohumeral arthrodesis.
