Ultrasound Imaging and Guidance in the Management of Adhesive Bursopathy of the Shoulder: A Video Demonstration

Fibro-adhesive Bursitis: A Novel Sonographic Finding in Adhesive Capsulitis Patients and a Proposal of Management

INTRODUCTION

Adhesive capsulitis, also known as "frozen shoulder," is a debilitating shoulder condition increasingly linked to fibroadhesive bursitis, particularly after COVID-19 and related vaccinations. There is no definitive gold standard for its treatment, the primary therapeutic objectives of which are the reduction of pain and the restoration of shoulder range of motion. The aim of our study was to analyze treatment outcomes based on quantitative measures of shoulder function and symptom relief.

METHOD

Conducted between January 2022 and April 2023, the research involved 45 patients initially diagnosed with adhesive capsulitis and associated fibroadhesive bursitis. After excluding nine patients for other concomitant pathologies (five for calcific tendinopathy and four for rotator cuff injury), 36 patients were randomized into two groups: one group was treated with glenohumeral hydrodistension, the other with glenohumeral hydrodistension combined with bursal injection. Assessments were conducted at baseline and then 2, 4, and 6 months after treatment, focusing on changes in pain levels, functional scores, and range of motion in all planes. Each group followed a home-based rehabilitation protocol.

RESULTS

Significant improvements were observed in both treatment groups, with the combined hydrodistension and bursal injection group showing notably superior outcomes. Specifically, the range of motion in flexion improved from an initial median of 80° to 155° in the combined treatment group, compared to an increase from 75.5° to 129° in the group treated with hydrodistension alone. This enhancement was statistically significant (p < 0.001). Regarding pain reduction, the combined treatment group demonstrated a dramatic decrease in visual analogue scale (VAS) scores, from a baseline median of 7 to 1 at the 6-month follow-up. In contrast, the hydrodistension-only group showed a reduction from 7 to 3, with these differences also proving statistically significant (p < 0.001).

CONCLUSIONS

Ultrasound-guided hydrodistension of the glenohumeral joint, if combined with bursal injection and specific exercises, effectively reduces pain, decreases disability, and improves range of motion in patients with second-stage adhesive capsulitis. This study highlights the importance of a combined approach in the management of this complex condition, especially after the histological changes that occurred after COVID-19 and related vaccinations.

Musculoskeletal disorders in padel: from biomechanics to sonography

Padel is a racket sport, combining high-frequency and low-intensity athletic gestures, that has been gaining growing scientific interest in recent years. Musculoskeletal injuries are very common among padel players with an incidence rate of 3 per 1000 h of training and 8 per 1000 matches. To the best of our knowledge, a comprehensive collection describing the most common sonographic findings in padel players with musculoskeletal injuries is lacking in the pertinent literature. In this sense, starting from the biomechanical features of padel-specific gestures we have reported the ultrasonographic patterns of most frequent injuries involving the upper limb, the trunk, and the lower limb. Indeed, comprehensive knowledge of the biomechanical and clinical features of musculoskeletal injuries in padel is paramount to accurately perform a detailed ultrasound examination of the affected anatomical site. So, the present investigation aims to provide a practical guide, simple and ready-to-use in daily practice, to optimize the sonographic assessment of padel players by combining it with the clinical findings and the biomechanical features of athletic gestures.

Adhesive capsulitis after COVID-19 vaccine injection: a peculiar case treated with combined bursa distention and glenohumeral capsular hydrodilatation

Frozen shoulder is a common and self-limiting condition affecting the soft tissues of the shoulders, characterized by severe pain, impaired range of motion (ROM) and limitation of daily activities. Its prevalence is 5% and it occurs most commonly in the fifth and sixth decades of life; women are more affected [DePalma in Clin Orthop Relat Res 466:552-560, 2008]. It can be idiopathic or associated with other conditions such as metabolic disorders, diabetes, thyroid diseases, prolonged immobilization, trauma [DePalma in Clin Orthop Relat Res 466:552-560, 2008], or complications after vaccine administration known as SIRVA (Shoulder injury related to vaccine administration). SIRVA is not caused by the vaccine itself but by inappropriate vaccination techniques [Martín Arias et al. in Vaccine 35:4870-4876, 2017]. The natural history of the frozen shoulder is a progression through three stages based on clinical and arthroscopic presentations: freezing, frozen and thawing [DePalma in Clin Orthop Relat Res 466:552-560, 2008; Do et al. in Orthop J Sport Med 9:232596712110036, 2021]. The onset is characterized by disabling pain, that worsens at night; it is induced by inflammation and hypervascularity and lasts from 10 to 36 weeks [Do et al. in Orthop J Sport Med 9:232596712110036, 2021]. The second stage is predominated by stiffness and severe reduction of ROM. This phase typically lasts from 9 to 12 months [Do et al. in Orthop J Sport Med 9:232596712110036, 2021]. Eventually, a recovery phase occurs, with a gradual recovery of the ROM that can last between 12 and 42 months. Ultrasound is an emerging diagnostic tool that contributes to differential diagnosis and treatment [Zappia et al. in Insights Imaging 7:365-371, 2016; Ricci et al. in J Ultrasound Med 39:633-635, 2020]: signs of adhesive capsulitis consist of thickening of the inferior recess of the glenohumeral joint capsule, thickening of the coracohumeral ligament and soft tissue structures in the rotator cuff interval, with hypervascularity. An unspecific sign is increased fluid in the tendon sheath of the long head of the biceps [Martín Arias et al. in Vaccine 35:4870-4876, 2017; Tandon et al. in J Ultrasound 20:227-236, 2017].

Ultrasound-Guided Infiltrative Treatment Associated with Early Rehabilitation in Adhesive Capsulitis Developed in Post-COVID-19 Syndrome

Background and Objectives: Post-COVID-19 syndrome is commonly used to describe signs and symptoms that continue or develop after acute COVID-19 for more than 12 weeks. The study aimed to evaluate a treatment strategy in patients with adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome. Materials and Methods: The method used was an interventional pilot study in which 16 vaccinated patients presenting with the clinical and ultrasound features of adhesive capsulitis (phase 1) developed during post-COVID-19 syndrome were treated with infiltrative hydrodistension therapy under ultrasound guidance associated with early rehabilitation treatment. Results: Sixteen patients with post-COVID-19 syndrome treated with ultrasound-guided infiltration and early rehabilitation treatment showed an important improvement in active joint ROM after 10 weeks, especially in shoulder elevation and abduction movements. The VAS mean score before the treatment was 6.9 ± 1.66. After 10 weeks of treatment, the VAS score was 1 ± 0.63. Conclusions: The study demonstrated that the management of adhesive capsulitis (phase 1) developed in post-COVID-19 syndrome, as conducted by physiotherapists in a primary care setting using hydrodistension and a rehabilitation protocol, represented an effective treatment strategy.

The Value of Percutaneous Ultrasound-Guided Subacromial Bursography for Rotator Cuff Tear in Elderly Patients with Shoulder Pain

Objective

Based on the analysis of the images of acromial slide, we explored the application of percutaneous ultrasound-guided subacromial bursography (PUSB) on rotator cuff tear (RCT) in diagnosing elderly patients with shoulder pain.

Methods

Eighty-five patients who were clinically diagnosed with RCT and underwent PUSB examination in the department of ultrasound in our hospital were enrolled as the subjects. Independent samples t-test was used to analyze the general characteristics. Based on the gold standard of shoulder arthroscopy, the diagnostic efficacy of ultrasound, magnetic resonance imaging (MRI), and PUSB was evaluated. The sensitivity, specificity, positive and negative predictive values, and accuracy were calculated as well. The consistency of these techniques with shoulder arthroscopy in diagnosing the RCT stage was additionally compared using Kappa test.

Results

In patients with large full-thickness RCT, the 100% detection rate was achieved by the techniques of ultrasound, MRI, and PUSB. For patients with small full-thickness RCT, the detection rate of PUSB (100%) was evidently higher than those of ultrasound and MRI. Similar results were shown in the detection rates of patients with bursal-side partial-thickness RCT (90.5%) and articular-side partial-thickness RCT (86.9%). More importantly, the sensitivity, specificity, and accuracy of PUSB in patients with both full-thickness RCT and partial-thickness RCT were significantly better than those of ultrasound and MRI.

Conclusion

PUSB has a better efficacy in the detection of RCT than ultrasound and MRI, showing its feasibility as an important imaging method to evaluate the degree of RCT.

Clinical/Sonographic Assessment and Management of Calcific Tendinopathy of the Shoulder: A Narrative Review

Shoulder disorders are very common in clinical practice. Among several other pathologies, calcific tendinopathy of the rotator cuff tendons is frequently observed during the ultrasound examination of patients with painful shoulder. The deposition of hydroxyapatite calcium crystals should not be considered as a static process but rather a dynamic pathological process with different/possible patterns of migration. In this paper, we have illustrated how and where these calcium depositions can migrate from the rotator cuff tendons to the peri-articular soft tissues. We have also tried to discuss the issue from the clinical side, i.e., how these particular conditions might impact the specific diagnosis, appropriate rehabilitation plan or interventional approach for optimal functional recovery.

Clicking shoulder due to snapping Subacromial subdeltoid (SASD) bursitis: a case report of an unusual presentation in clinical practice with imaging features

A spectrum of pathologies can cause clicking, popping or snapping of the shoulder joint. These can lead to a patient seeking attention in clinical practice due to pain, discomfort and impact on activities of daily living. Traditionally these can originate from pathologies which involve biceps tendon, tears of the rotator cuff or the glenoid labrum, articular cartilage or due to loose bodies and scapulothoracic joint dysfunction [Guillin et al. in Br J Radiol 85:1343-1353, 2012; Vidoni et al. in Indian J Musculoskelet Radiol 4:61-69, 2022]. Subacromial subdeltoid (SASD) bursitis is a well-described entity and one of the commonest causes of shoulder pain. We present SASD bursitis as an unusual cause of clicking/snapping in the shoulder without associated pain in a healthy young male. The clinical presentation, diagnostic strategy with complementary imaging and the role of interventional radiology in its effective management is highlighted to support clinicians faced with a diagnostic dilemma.

A retrospective study of ultrasound-guided intervention for frozen shoulder in the frozen stage

Background

To investigate the clinical value of ultrasound (US)-guided intervention for frozen shoulder (FS) in the frozen stage.

Methods

This study included 40 patients who had primary FS in the frozen stage and were evaluated by US. These 40 patients have all received conservative treatment elsewhere, and no satisfactory results have been achieved, with no improvement in active and passive movement angles, and no improvement in scores within 3 months. Therefore, their previous treatment was set as comparison. All patients underwent US-guided shoulder joint capsule distension by injection of sterilized water. Of these participants, 22 patients with scapulohumeral periarthritis received a compound betamethasone injection, and 14 patients with thickened coracohumeral ligaments (CHLs) underwent acupotomy lysis, and the remaining 4 patients had no extra treatments. The Constant-Murley score (CMS) was evaluated before and after the operation and analysed for each patient.

Results

Before treatment, the indices for the thickening of the subaxillary joint capsule, subacromial bursa (with or without effusion), long head of the biceps brachii tendon (LHBBT) and CHL were 40, 22, 16 and 14, respectively. After treatment, all the indices were significantly decreased (all P < 0.010) except for that of the LHBBT (P = 0.123). The patients' CMSs improved, with the median total CMS increasing from 59 points (interquartile range: 53–64 points) to 86 points (interquartile range: 78–90 points) (P < 0.010). While the internal rotation (Ir) of the shoulder joint did not improve (FDRs < 0.50), abduction, forward flexion (Ff) and external rotation (Er) improved significantly (all FDRs = 1.00).

Conclusion

Compared with conservative treatment, US-guided intervention for FS in the frozen stage is highly effective and of great clinical value.

EURO-MUSCULUS/USPRM Dynamic Ultrasound Protocols for Shoulder

ABSTRACT

In this dynamic protocol, ultrasound examination of the shoulder using different maneuvers is described for several/relevant shoulder problems. Scanning videos are coupled with real-time patient examination videos for better understanding. The authors believe that this practical guide prepared by an international consensus of several experts (EURO-MUSCULUS: European Musculoskeletal Ultrasound Study Group and USPRM: Ultrasound Study Group of ISPRM [International Society of Physical and Rehabilitation Medicine]) will help musculoskeletal physicians perform a better and uniform/standard approach.
