Sonography of the biceps tendon of the shoulder: normal and pathologic findings.

Abnormalities of the tendon of the long head of the biceps brachii muscle commonly associate with other lesions about the shoulder, especially rotator cuff rupture, and are a frequent cause of a painful shoulder. As pathognomonic clinical signs of these lesions are often lacking, noninvasive imaging techniques are practical and valuable. In this report the anatomy of this tendon is described, correlating with sonographic images. Examination technique and typical sonographic findings in pathologic conditions affecting the long bicipital tendon sheath, the substance of the tendon, and the position of the tendon are illustrated. Their distinction is important to proper patient management.

Corticosteroid injections for shoulder pain.

BACKGROUND: While many treatments, including corticosteroid injections in and around the shoulder, are advocated to be of benefit for shoulder pain, few are of proven efficacy. This review of corticosteroid injections for shoulder pain is one in a series of reviews of varying interventions for shoulder disorders. OBJECTIVES: To determine the efficacy and safety of corticosteroid injections in the treatment of adults with shoulder pain. SEARCH STRATEGY: MEDLINE, EMBASE, CINAHL, Central and Science Citation Index were searched up to and including June 2002. SELECTION CRITERIA: Randomised and pseudo-randomised trials in all languages of corticosteroid injections compared to placebo or another intervention, or of varying types and dosages of steroid injection in adults with shoulder pain. Specific exclusions were duration of shoulder pain less than three weeks, rheumatoid arthritis, polymyalgia rheumatica and fracture. DATA COLLECTION AND ANALYSIS: Trial inclusion and methodological quality was assessed by two independent reviewers according to predetermined criteria. Results are presented separately for rotator cuff disease, adhesive capsulitis, full thickness rotator cuff tear and mixed diagnoses, and, where possible, combined in meta-analysis. MAIN RESULTS: Twenty-six trials met inclusion criteria. The number, site and dosage of injections varied widely between studies. The number of participants per trial ranged from 20 to 114 (median 52 participants). Methodological quality was variable. For rotator cuff disease, subacromial steroid injection was demonstrated to have a small benefit over placebo in some trials however no benefit of subacromial steroid injection over NSAID was demonstrated based upon the pooled results of three trials. For adhesive capsulitis, two trials suggested a possible early benefit of intra-articular steroid injection over placebo but there was insufficient data for pooling of any of the trials. One trial suggested short-term benefit of intra-articular corticosteroid injection over physiotherapy in the short-term (success at seven weeks RR=1.66 (1.21, 2.28). REVIEWER'S CONCLUSIONS: Despite many RCTs of corticosteroid injections for shoulder pain, their small sample sizes, variable methodological quality and heterogeneity means that there is little overall evidence to guide treatment. Subacromial corticosteroid injection for rotator cuff disease and intra-articular injection for adhesive capsulitis may be beneficial although their effect may be small and not well-maintained. There is a need for further trials investigating the efficacy of corticosteroid injections for shoulder pain. Other important issues that remain to be clarified include whether the accuracy of needle placement, anatomical site, frequency, dose and type of corticosteroid influences efficacy.

Work-related musculoskeletal symptoms among sheet metal workers.

We report results of two pilot studies of the relationship between musculoskeletal disorders and work tasks in sheet metal workers. These two studies were undertaken as pilot investigations to determine if symptoms of carpal tunnel syndrome or other work-related musculoskeletal symptoms are present in sheet metal workers, and to determine if we could begin to identify the factors in sheet metal work that cause them. In the first study, telephone interviews were conducted with 18 disabled sheet metal workers; the second survey entailed self-administered questionnaires completed by 47 active and retired sheet metal workers. Among the disabled workers, rotator cuff cases reported the greatest percent of time spent hanging duct, an overhead task commonly carried out during field work. Carpal tunnel cases reported more hand tool use than the rotator cuff cases. The questionnaire survey of active and retired workers found the proportion of time spent in a sheet metal shop (contrasted with field work) to be positively associated with hand symptoms; sheet metal workers who spent at least 65% of their time in the shop had an odds ratio of 3.4 for symptomatic hand cumulative trauma disorder (CTD) (p = 0.12). The proportion of time spent hanging duct was positively associated with both neck and shoulder symptoms, with odds ratios of 7.9 (p = 0.08) and 2.7 (p = 0.16), respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

Editorial Commentary: Stiff Patients After Rotator Cuff Repair: How Many Had Underrecognized Preoperative Adhesive Capsulitis?

Stiffness after rotator cuff repair is one of the most common sources of disability and one of the most common complications. Smoking, diabetes, Workers' compensation status, and traumatic tears are among the strongest risk factors. This is important information in setting appropriate expectations for both the patient and the surgeon preoperatively. Some of these factors are also associated with preoperative stiffness, so surgeons should maintain a high index of suspicion for concomitant adhesive capsulitis in patients presenting with limited motion, particularly in diabetic and non-English speaking populations. In cases where both a rotator cuff tear and adhesive capsulitis coexist, performing a concurrent capsular release or manipulation during the index procedure may improve functional outcomes and reduce the necessity for secondary surgical intervention.

Comparison of clinical and patient-based measures to assess medium-term outcomes following shoulder surgery for disorders of the rotator cuff.

OBJECTIVE: To compare different assessments following shoulder surgery for impingement syndrome with or without rotator cuff tear or repair. METHODS: A prospective study of 93 patients was conducted. Standard assessments were performed before, at 6 months, and at 4 years following shoulder surgery using the patient-based Oxford Shoulder Score (OSS), the Medical Outcomes Study Short Form-36 (SF-36) questionnaire, and a surgeon-assessed Constant Shoulder Score. Patients were categorized according to the surgery received in relation to the presence of cuff tears: full repair, partial repair, cuff tear/no repair, no tear/no repair. RESULTS: Most patients (57%) received subacromial decompression for impingement with no cuff tear. This group had the fewest pre- and postoperative symptoms. The category of patients who received only partial repair of a cuff tear had worse scores on all outcome assessments compared with other groups. Patient-based measures were more stable over time than the Constant. CONCLUSION: The shoulder-specific measures had greater sensitivity than the SF-36 in registering significant differences in outcomes between comparison groups at 6 months and 4 years.

Feeling good rather than feeling better matters more to patients.

OBJECTIVE: To determine the most appropriate means to assess the response to treatment in terms of pain and functional impairment in a chronic rheumatic condition (knee osteoarthritis [OA]) and an acute rheumatic condition (rotator cuff syndrome [RCS]). METHODS: Two prospective studies were conducted consisting of 1,019 outpatients with knee OA and 271 patients with acute RCS. The minimal clinically important improvement and the patient acceptable symptom state were determined for knee OA pain using a visual analog scale, and for knee OA function using the Western Ontario and McMaster Universities Osteoarthritis Index function subscale; for acute RCS pain, a numeral rating scale was used, and the Neer function subscale was used for RCS function. RESULTS: The minimal clinically important improvement was shown to be the change required to achieve the patient acceptable symptom state, whatever the baseline level of symptom, the outcome (pain or function), or type of condition (chronic or acute). This acceptable state for pain was higher for chronic (27.0-36.4 across the baseline score) than acute (16.7-24.1) conditions. The level of functional impairment considered satisfactory by patients with knee OA was higher for more disabled patients (43.1) than for less disabled patients (20.4). CONCLUSION: Patients consider that they experienced an important improvement only if this improvement allowed them to achieve a state they consider satisfactory. The most appropriate means to assess the response to therapy seems to be to assess whether patients feel good (i.e., achieve the patient acceptable symptom state).

Quantitative morphology of full thickness rotator cuff tears.

The occurrence of full thickness rotator cuff tears (RCTs) at time of death, the size and distribution of those tears among the tendons of the rotator cuff, and the anterior to posterior and medial to lateral dimensions of the RCTs were determined. A subset of 57 shoulders from a group of 414 were found to have full thickness rotator cuff tears. The three-dimensional coordinates of specific bony landmarks and points defining the circumference of the RCT were digitized using a Flock of Birds DC electromagnetic tracking device. Bony landmarks were used to determine the separation between adjacent tendons of the rotator cuff. Points describing the circumference of the RCT were used to calculate the area of the tear. The majority of tears occurred in the supraspinatus tendon alone (25), or in both the supraspinatus and infraspinatus tendons (22). The areas of the RCTs ranged from 0.07 cm(2) to 19.17 cm(2) with an average of 4.43 cm(2). The mean anterior to posterior length was 1.95 cm. The mean medial to lateral length was 1.98 cm.

Correlation between the four types of acromion and the existence of enthesophytes: a study on 423 dried scapulas and review of the literature.

The purpose of this study was to correlate the four types of acromial shape with the existence of enthesophytes, which together comprise two important parameters for subacromial impingement syndrome and rotator cuff tears. In addition, a review of the literature was carried out. Four hundred twenty-three dried scapulas were studied at the Department of Anatomy in the University of Cologne, Germany. Four types of acromion were found: the three classical ones as described by Bigliani et al. ([1986] Orthop Trans 10:216) and a fourth one, where the middle third of the undersurface of acromion was convex (Gagey et al. [1993] Surg Radiol Anat 15:63-70). The correlation between the four types of acromion and the presence of enthesophytes at its anterior undersurface was also recorded. The distribution of acromial types was as follows: type I, flat, 51 (12.1%); type II, curved, 239 (56.5%); type III, hooked, 122 (28.8%); and type IV, convex, 11 (2.6%). Enthesophytes were found in 1 of type I (2%), in 19 of type II (7.9%), in 46 of type III (37.7%), and in 0 (0%) of type IV acromions. Overall, 66 (15.6%) out of 423 scapulas had enthesophytes. In all cases, they were localized at the site of the coracoacromial ligament insertion on the acromion. Enthesophytes were significantly (P < 0.05) more common in type III acromions and this combination is particularly associated with subacromial impingement syndrome and rotator cuff tears. In type I and in type IV acromions, the incidence of enthesophytes is very small and, according to other studies, with these two acromial types rotator cuff tears are also rare.

Sonography of the shoulder after arthrography (arthrosonography): preliminary results.

PURPOSE: The purpose of this study was to verify whether arthrosonography improves diagnostic accuracy in diseases of the shoulder and provides additional information for therapeutic planning, compared with conventional sonography. METHODS: We prospectively studied 113 consecutive patients with chronic shoulder pain. Sonography was performed before and after arthrography, with the radiologist blinded to the results of arthrography. When a rotator cuff tear was detected sonographically, its type, location, and size were recorded; we also evaluated any changes in the subacromial-subdeltoid bursa and any abnormalities in the biceps tendon sheath. The diagnostic accuracy of conventional sonography and arthrosonography was compared with that of arthrography for rotator cuff tear. Changes in the subacromial-subdeltoid bursa and biceps tendon sheath seen on conventional sonography were also compared with those seen on arthrosonography. RESULTS: The sensitivity and specificity of conventional sonography in the diagnosis of rotator cuff tear were 86% (25/29) and 95% (80/84), respectively; for arthrosonography, the values were 97% (28/29) and 95% (80/84), respectively. The differences in sensitivity and specificity for the 2 sonographic techniques were not statistically significant (p > 0.05). The accuracy in localizing the tear was also not significantly different between the 2 sonographic techniques. Synovial proliferation was more easily detected with arthrosonography than it was with conventional sonography in the subacromial-subdeltoid bursa (p < 0.01) and in the biceps tendon sheath (p < 0.0001). CONCLUSIONS: Our preliminary results suggest that although arthrosonography was not superior to conventional sonography in the diagnosis of rotator cuff tears, it may provide a better assessment of the size of tears and additional information about synovial proliferation in the subacromial-subdeltoid bursa and the biceps tendon sheath.

Interobserver variation in sonography of the painful shoulder.

PURPOSE: This study was conducted as a prospective assessment of interobserver variability in the sonographic evaluation of the rotator cuff. METHODS: Three musculoskeletal radiologists who had different levels of scanning experience each performed shoulder sonography on 24 consecutive patients during 1 patient visit. The diagnostic criteria full-thickness rotator cuff tear, tendon calcification, tendinosis of the supraspinatus, subacromial fluid, subacromial synovial/bursal thickening, dynamic signs of impingement, and abnormality in the long head of biceps tendon were scored, with independent observers recording the data. Statistical analysis was performed using Cohen's kappa test, with significance assessed at p values of less than 0.05. RESULTS: There was good agreement (kappa >0.60, p <0.01) between the experienced operators for full-thickness rotator cuff tear, tendon calcification, dynamic signs of impingement, and abnormality of the long head of biceps tendon. There was no significant agreement between the experienced operators and the less experienced operator in several categories, including (and importantly) full-thickness rotator cuff tears (kappa=0.18-0.21). CONCLUSIONS: In experienced hands sonography of the rotator cuff is a reproducible diagnostic test, but agreement is poor when there is marked disparity between the operators' experience levels. Our findings suggest a need for a more clearly defined training curriculum for sonography of the shoulder in radiology training programs.

Dynamic ultrasonography of rotator cuff muscles.

PURPOSE: To confirm the neuromuscular integrity of the rotator cuff and to investigate the effect of different contraction patterns on shoulder function, we sonographically analyzed dynamic contraction patterns of this muscle group. METHODS: Fifty supra- and 50 infraspinatus muscle contraction patterns of patients with different shoulder pathologies examined with a 7.5-MHz transducer were recorded and saved as video files. Both data sets were analyzed by 3 independent observers who then assigned a grade to each contraction pattern: normal, slightly disturbed, severely disturbed, or no contraction. Intra- and inter-observer variations were calculated. In 43 patients with isolated supraspinatus tears, the clinical relation to shoulder function as measured with the Constant score was evaluated. RESULTS: In the 100 cases tested, the intraclass correlations for the 3 observers were 0.82, 0.88, and 0.88. The inter-observer reliability was 0.74. No pair of first and second readings for either the supraspinatus or infraspinatus muscle differed by more than 1 grade. In patients with a supraspinatus tear, the contraction type of the supraspinatus correlated significantly with the Constant score (p=0.02). CONCLUSIONS: When dynamic ultrasonography is used to assess the contraction patterns of the supra- and infraspinatus muscles, good intra- and inter-observer reliability is attained. Because a better contraction type correlates significantly with better shoulder function, this new diagnostic criterion may improve decision-making in the treatment of shoulder diseases.

Sonography of the rotator cuff in painful shoulders performed without knowledge of clinical information: results from 58 sonographic examinations with surgical correlation.

PURPOSE: To assess the value of sonography as an isolated diagnostic test for the detection and quantification of rotator cuff tears. METHODS: Preoperative sonographic examination was performed on 58 shoulders. Key biases on sonographic interpretation such as history-taking, physical examination, or concurrent imaging examinations were excluded by way of blinding. Tears of the rotator cuff were the positive findings of interest. Assessment of tear size and localization was done sonographically, and the results were compared with operative findings. RESULTS: All 24 full-thickness tears observed at surgery had been diagnosed correctly via sonography. In 19 of 20 cases with an intact rotator cuff, preoperative sonography was negative. Thirteen of 14 partial-thickness tears were not detected via sonography; 1 was misinterpreted as a full-thickness tear. Location of the tears relative to the rotator cuff tendons was described correctly in 21 of 25 cases. For tear size measurement, the 95% range of agreement was less than +/-1 cm. CONCLUSIONS: Blinded sonographic examination is effective in the detection and quantification of full-thickness tears of the rotator cuff but lacks sensitivity in the detection of partial-thickness tears.

Distribution of normal and abnormal fluid collections in the glenohumeral joint: implications for MR arthrography.

Although magnetic resonance (MR) images of the glenohumeral joint frequently demonstrate intraarticular fluid, no specific criteria have, to the authors' knowledge, been published that allow accurate assessment of the amount of fluid present. Also, despite the increasing use of MR arthrography of the shoulder, the optimal amount of intraarticular fluid that should be used with this technique has not been determined. The authors progressively distended the glenohumeral joint in six cadaveric shoulder specimens with a dilute gadopentetate dimeglumine solution and obtained MR images after injection of 2, 5, 10, 15, and 20 mL of the solution. The pattern of fluid distribution was evaluated, and these results were then used to estimate the amount of fluid that was present in the glenohumeral joint on MR images of 20 shoulders obtained in 12 asymptomatic volunteers. In 14 of these shoulders, intraarticular fluid was present; however, in none was more than 2 mL evident. Results of the cadaveric study also indicated that 15 mL of intraarticular fluid appears to be the optimal amount for MR arthrography.

Comparison of fat-saturation fast spin echo versus conventional spin-echo MRI in the detection of rotator cuff pathology.

The purpose of this study was to compare the diagnostic performance of fat-saturation fast-spin-echo (FSE) T2-weighted (T2W) sequences with conventional spin-echo (CSE) T2W sequences in the detection of rotator cuff pathology using surgery as the reference standard. Oblique coronal dual-echo CSE and FSE T2W images with fat saturation from 50 surgically confirmed MR shoulder examinations were acquired on a 1.5-T MR scanner. Blinded MR readers retrospectively analyzed each imaging sequence separately and ultimately correlated both sequences together with findings at surgery. FSE was 100% sensitive and 94% specific in detection of full-thickness tears (n = 19) and 73% sensitive and 97% specific in the detection of partial-thickness rotator cuff tears (n = 13). There was no statistically significant difference in the performance of FSE with fat saturation compared with CSE. The two discrepancies between imaging sequences related to the extent of partial-thickness tears. Our findings suggest that fat-saturation FSE imaging can effectively replace CSE imaging in the evaluation of rotator cuff pathology.

Assessment of the rotator cuff and glenoid labrum using an extremity MR system: MR results compared to surgical findings from a multi-center study.

PURPOSE: To conduct a multi-center assessment of the use of a 0.2-T, extremity MR system (E-scan; General Electric Lunar Corp. and Esaote, Genoa, Italy) for identifying tears of the rotator cuff and glenoid labrum. MATERIALS AND METHODS: A retrospective study was performed involving 160 patients (age range, 15-84 years old) from five facilities in the United States, comparing shoulder MR imaging to surgical findings. MR imaging of the shoulder was conducted as follows: shoulder coil; T1-weighted spin echo, coronal-oblique and axial images; short Tau inversion recovery (STIR), coronal-oblique images and axial images; and T2-weighted spin echo, coronal-oblique and sagittal-oblique images. The MR examinations were interpreted in an independent, prospective manner by two radiologists with extensive musculoskeletal MRI experience. Arthroscopic (N = 103) or open surgical (N = 57) procedures were performed within a mean of 53 days after MR imaging. RESULTS: Surgical findings demonstrated rotator cuff tears in 131 patients and labral tears in 60 patients. For the rotator cuff, the sensitivity, specificity, positive predictive value, and negative predictive value were 90%, 93%, 98%, and 68%, respectively. For the labrum, the sensitivity, specificity, positive predictive value, and negative predictive value were 55%, 100%, 100%, and 82%, respectively. CONCLUSIONS: There was good agreement when MR results obtained using the extremity MR system were compared to surgical findings for identifying rotator cuff tears, while the sensitivity of MR imaging for determining labral tears was relatively poor. Nevertheless, these findings were comparable to those reported in the peer-reviewed literature for MR systems operating at mid-, and high-field-strengths.
