Comparison of Ultrasound-Guided to Fluoroscopy-Guided Biceps Tendon Sheath Therapeutic Injection

Fluoroscopy-guided injections of the upper extremity: pearls and pitfalls

Fluoroscopy guidance is commonly utilized for injections in the upper extremity, with increased accuracy for injection placement compared to blind injection. Injection of the glenohumeral joint is the most commonly performed upper extremity procedure. However, there are a number of other sites which can be easily injected under fluoroscopy including the acromioclavicular joint, subacromial subdeltoid bursa, biceps tendon sheath, scapulothoracic bursa, elbow, wrist, first CMC joint, and pisotriquetral joint. Fluoroscopy can be used to guide injections into the glenohumeral, elbow, or wrist joints preceding MR arthrography. While there are technique similarities when injecting any of these sites, some particular approaches and pitfalls are unique to each anatomic site.

ACR Appropriateness Criteria® Chronic Shoulder Pain: 2022 Update

Chronic shoulder pain is an extremely common presenting complaint. Potential pain generators include the rotator cuff tendons, biceps tendon, labrum, glenohumeral articular cartilage, acromioclavicular joint, bones, suprascapular and axillary nerves, and the joint capsule/synovium. Radiographs are typically the initial imaging study obtained in patients with chronic shoulder pain. Further imaging may often be required, with modality chosen based on patient symptoms and physical examination findings, which may lead the clinician to suspect a specific pain generator. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

The long head of biceps at the shoulder: a scoping review

BACKGROUND

This review aimed to explore the available literature to update our understanding of the long head of biceps (LHB) at the shoulder. Synthesise our findings to identify emergent themes and knowledge gaps to inform future research and management directions.

METHODS

PubMed, Embase, Cinahl, SportDiscus, CENTRAL, and Web of Science were searched from inception to 31st December 2021. Articles were included if they referenced adult participants > 18 years of age and were written in English.

RESULTS

214 articles were included in the final analysis, and results were categorised into six emergent themes: (1) Anatomy - Normal anatomical variation of the biceps from aberrant origins, third and fourth accessory heads, and an absence of the LHB tendon (LHBT) are not necessarily benign, with shoulder pain and instability a commonly reported theme. (2) Function - Bicep's role in glenohumeral elevation and stability in healthy shoulders is minimal. In contrast, LHB has a more significant role in shoulder stability and humeral head depression in subjects with rotator cuff failure or an absent LHBT. (3) Pathology - There is an association between LHB tendinopathy, rotator cuff disease, LHBT instability and occult rotator cuff tears. Early recruitment and hyperactivity of the LHB in subjects with symptomatic rotator cuff tears and instability suggest a potential compensatory role. (4) Assessment - The limited diagnostic utility of special orthopaedic tests in assessing LHBT pathology was a consistent theme. The utility of magnetic resonance imaging and ultrasound to identify full-thickness tendon tears and instability of the LHBT was moderate to high. However, the utility of clinical tests and imaging may be underestimated due to arthroscopy's limitations in fully visualising the proximal LHBT. (5) Non-Surgical Management - Ultrasound-guided injections into the biceps sheath show greater accuracy and patient outcomes than blinded injections; however, the entry of injectate into the intraarticular glenohumeral joint may have unwanted complications. (6) Surgical management - For the surgical management of biceps pathology with or without rotator cuff pathology, both biceps tenodesis and tenotomy report similar improvements in pain without any significant adverse effect on strength or function. Tenodesis favoured higher overall constant scores and a lower incidence of Popeye deformity and cramping arm pain, with tenotomy trending to be more cost and time effective. For patients with a healthy LHBT, rotator cuff repair with adjunctive tenodesis or tenotomy fails to provide additional clinical improvements compared to rotator cuff repair in isolation.

CONCLUSIONS

The scoping review highlights the variability of biceps anatomy, which is not necessarily benign and suggests a minimal role of the LHB in shoulder elevation and stability in healthy individuals. In contrast, individuals with rotator cuff tears experience proximal humeral migration and demonstrate hyperactivity of the LHB, suggesting a potential compensation role. The observed prevalence of LHBT pathology with rotator cuff tears is well established; however, the cause-and-effect relationship between LHBT pathology and rotator cuff disease is undetermined. The diagnostic utility of clinical tests and imaging to exclude LHBT pathology may be understated due to the limitations of arthroscopy to visualise the proximal LHBT fully. Rehabilitation programs for the LHB are understudied. Similar post-surgical clinical outcomes are observed for tenodesis and tenotomy for biceps and rotator cuff-related shoulder pain. Subjects undergoing biceps tenodesis are less likely to have cramping arm pain and a Popeye deformity than patients undergoing biceps tenotomy. The significance of routine surgical removal of the LHBT and sequelae on rotator cuff tear progression to failure and long-term shoulder function is unknown, and further research is required.

Interventional Radiology Procedures of the Shoulder

Using imaging guidance to perform procedures around the shoulder girdle has become established practice in musculoskeletal radiology. Whether it be therapeutic injections for intra-articular pathology, rotator cuff or subacromial/subdeltoid bursal pathology, or injections for diagnostic purposes, such as magnetic resonance or computed tomography arthrography, a range of techniques and imaging modalities can be used. This article discusses the techniques for commonly performed procedures.

The Effectiveness of Ultrasound-Guided Subacromial-Subdeltoid Bursa Combined With Long Head of the Biceps Tendon Sheath Corticosteroid Injection for Hemiplegic Shoulder Pain: A Randomized Controlled Trial

Background

Subacromial-subdeltoid (SASD) bursa and long head of the biceps tendon (LHBT) sheath corticosteroid injection are commonly used to treat shoulder pain associated with arthritic shoulder conditions, but effectiveness in the stroke population is unclear. This study aimed to investigate the clinical effectiveness of ultrasound-guided SASD bursa combined with LHBT sheath corticosteroid injection for hemiplegic shoulder pain (HSP) compared with SASD bursa injection alone.

Methods

60 patients with HSP were randomly allocated to the dual-target group (n = 30) and single-target group (n = 30). The single-target group received SASD bursa corticosteroid injection alone, and the dual-target group received SASD bursa and LHBT sheath corticosteroid injection. The primary endpoint was pain intensity measured on a visual analog scale (VAS). The secondary endpoint was passive range of motion (PROM) of the shoulder, Upper Extremity Fugl-Meyer assessment (UEFMA) score, and Modified Barthel Index (MBI) score. PROM and pain intensity VAS were assessed at baseline and weeks 1, 4, and 12 post-treatment. UEFMA and MBI were recorded at baseline and weeks 4 and 12 post-treatment.

Results

A total of 141 patients with HSP were screened, and 60 patients were included. Significant differences in the VAS, PROM, UEFMA and MBI were observed at all follow-ups in both groups. The dual-target group showed a significant difference in VAS score compared with the single-target group (3.3 vs. 3.7, p = 0.01) at week 4 and week 12 (2.5 vs. 3.2, p < 0.001). Moreover, the dual-target group showed statistically significant differences in flexion (p < 0.001) at week 12, extension rotation (p < 0.001) at week 12, and abduction at week 1 (p = 0.003) and weeks 4 and 12 (p < 0.001) compared with the single-target group. There were significant differences in FMA and MBI scores in the two groups before and after treatment (p < 0.001), with a more significant increase in the dual-target group compared with the single-target group (p < 0.001) at week 12.

Conclusion

The combination of SASD bursa and LHBT sheath corticosteroid injection is superior to SASD bursa injection alone in reducing shoulder pain and improving functional activities in patients with HSP.

The Effectiveness of Dry Needling Combined With Therapeutic Exercises in Treating Tendinopathy Conditions: A Systematic Review

CONTEXT

Approximately 70,000 Americans miss work annually due to tendinopathies causing pain, disability, and lower quality of life. Various conservative treatments have been demonstrated to improve outcomes in these conditions. Dry needling (DN) and therapeutic exercise are 2 such interventions that have been proposed to be a positive intervention for addressing tendinopathy.

OBJECTIVE

To summarize the best available evidence on the use of DN and exercise combined to treat tendinopathy.

EVIDENCE ACQUISITION

PubMed, EBSCOHost, and Web of Science were systematically searched from inception to March 2021. Articles were assessed to determine eligibility and evaluated for methodological quality using the PEDro scale. The PRISMA guidelines were used for this review. Inclusion criteria consisted of use of DN in combination with therapeutic exercise, human participants, and active tendinopathy pathology.

EVIDENCE SYNTHESIS

Seven studies met the inclusion and exclusion criteria, which averaged 6/11 on the PEDro scale. The level of agreement of evaluators was 94%. Current evidence supports the use of DN combined with therapeutic exercises, especially those including eccentric exercises, can improve pain and function for various tendinopathies. However, limited evidence exists regarding specific therapeutic interventions to be combined with DN.

CONCLUSION

There is moderate, level B evidence to suggest the use of DN techniques targeted at the tendon and combined with eccentric therapeutic exercise to improve pain and functional outcomes for tendinopathies.

Value of imaging to guide interventional procedures in rheumatic and musculoskeletal diseases: a systematic literature review informing EULAR points to consider

OBJECTIVES

To summarise current data on the value of imaging to guide interventional procedures in patients with rheumatic and musculoskeletal disease (RMDs) informing an European Alliance of Associations for Rheumatology taskforce.

METHODS

A systematic literature review was conducted to retrieve prospective and retrospective studies published in English and comparing different (imaging) techniques, different settings and procedural protocols to guide interventions in patients with RMDs. MEDLINE, EMBASE, the Cochrane Library and Epistemonikos databases were searched through October 2021. Risk of bias (RoB) was assessed using the Cochrane RoB tool for randomised trials V.2 (ROB2), the RoB tool for Non-Randomised Studies of Interventions and the appraisal tool for cross-sectional studies.

RESULTS

Sixty-six studies were included (most with moderate/high RoB); 49 were randomised controlled trials, three prospective cohort studies and 14 retrospective studies. Fifty-one studies compared either one imaging technique with another imaging technique, or with palpation-guided interventions. Ultrasound (US) was most frequently studied (49/51), followed by fluoroscopy (10/51). Higher accuracy was found for US or fluoroscopy compared with palpation-guided interventions. Studies comparing different imaging techniques (12/51) did not endorse one specific method. Different settings/equipment for imaging-guided procedures (eg, automatic vs manual syringes) were investigated in three studies, reporting heterogeneous results. Fifteen studies compared different imaging-guided procedures (eg, intra-articular vs periarticular injections).

CONCLUSION

Higher accuracy of needle positioning at joints and periarticular structures was seen in most studies when using imaging (especially US) guidance as compared with palpation-guided interventions with the limitation of heterogeneity of data and considerable RoB.

A Systematic Review of the Efficacy of Corticosteroid Injections of Tendon Sheaths, Excluding Stenosing Tenosynovitis of the Wrist and Hand

OBJECTIVE

Corticosteroid injections into tendon sheaths are common in clinical practice for treatment of a variety of tendon disorders. Previous systematic reviews have been performed on injections for stenosing tenosynovitis (DeQuervain tenosynovitis and trigger finger), but little high-level evidence remains for other tendon sheath injections. This systematic review analyzes the available literature on improvements in pain and function after these injections.

DESIGN

This systematic review of MEDLINE and Embase databases, as well as article bibliographies, examined studies of adult tendon sheath injections, excluding DeQuervain and trigger finger injections. Studies with and without comparison groups were examined. Risk of bias assessment was additionally performed.

RESULTS

Abstracts from 1293 records were screened, and 187 full-text articles were reviewed. Seven articles met final inclusion criteria, of which five were prospective trials and none were compared with a placebo. The proximal biceps, peroneal, finger flexor, and posterior tibialis tendons were explicitly examined. All articles reported at least short-term improvements in pain, and some reported improvement in function.

CONCLUSIONS

Low-quality studies exist that suggest tendon sheath injections may provide at least short-term improvement in pain. Controlled studies are required to fully demonstrate efficacy.

Ultrasound-Guided Biceps Tendon Sheath Injections Frequently Extravasate Into the Glenohumeral Joint

PURPOSE

To evaluate the frequency of glenohumeral joint extravasation of ultrasound (US)-guided biceps tendon sheath injections.

METHODS

Fifty shoulders with a clinical diagnosis of bicipital tenosynovitis pain received a US-guided biceps sheath injection with anesthetic, steroid, and contrast (5.0 mL mixture) followed immediately by orthogonal radiographs to localize the anatomic distribution of the injection. Radiographic evaluation of contrast localization was determined and interobserver reliability calculated.

RESULTS

All 50 postinjection radiographs (100%) demonstrated contrast within the biceps tendon sheath. In addition, 30 of 50 (60%) radiographs also revealed contrast in the glenohumeral joint. Interobserver reliability for determination of intraarticular contrast was good (kappa value 0.87).

CONCLUSIONS

US-guided bicipital sheath injections reproducibly result in intrasheath placement of injection fluid. Bicipital sheath injections performed with 5 mL of volume result in partial extravasation into the joint 60% of the time. These data may be useful for surgeons who use the results of diagnostic biceps injections for diagnosis and surgical decision-making.

Ultrasound-guided versus palpation-guided corticosteroid injections for tendinosis of the long head of the biceps: A randomized comparative study

PURPOSE

To compare accuracy, patient discomfort, and clinical outcome of ultrasound-guided versus palpation-guided corticosteroid injections to the bicipital groove in patients with long head of biceps (LHB) tendinosis.

MATERIALS AND METHODS

Forty-four patients with primary LHB tendinosis were randomized into two groups (group A, n = 22; group B, n = 22). All patients underwent treatment with a single corticosteroid injection to the bicipital groove. Injections in group A were performed under ultrasound-guidance, while in group B using a palpation-guided technique. The duration of each procedure was recorded. To assess accuracy, ultrasound examination was performed in both groups after injection. Patient discomfort was evaluated with visual analogue scale (VAS) for pain. The clinical outcome was assessed comparing the VAS, the Single Assessment Numeric Evaluation (SANE) score and the QuickDASH score before treatment and after 4 weeks and 6 months.

RESULTS

The mean duration of the procedure was 64 ± 6.87 s in group A and 81.91 ± 8.42 s in group B (p < 0.001). Injection accuracy in group A was 100% and in group B 68.18%. Discomfort was lower in group A, as compared to group B (22.10 vs. 35.50; p < 0.001). Symptoms, as measured by VAS, SANE and QuickDASH scores, improved in both groups at 4 weeks and 6 months (p < 0.05). Superior clinical improvement was recorded in group A in both time points (p < 0.05).

CONCLUSIONS

Corticosteroid injections are an effective treatment for primary LHB tendinosis. Under ultrasound guidance, injections to the bicipital groove are faster and produce lower discomfort. Superior accuracy and clinical outcomes can be achieved using the ultrasound-guided technique.

Level II; Prospective Randomized Comparative Study.

Ultrasound-Guided Biceps Tendon Sheath Injection: Spectrum of Preprocedure Appearances

OBJECTIVES

To determine the frequency of ultrasound (US) appearances of the extra-articular long head of the proximal biceps tendon in patients referred for US-guided biceps tendon sheath injections.

METHODS

We reviewed our US-guided biceps tendon sheath injections between January 2015 and December 2017, noting the appearance of the biceps tendon and sheath, as well as the needle size used, and what was injected. Clinical electronic medical records were also reviewed to determine safety and patients' responses.

RESULTS

A total of 300 US-guided biceps tendon sheath injections were performed for anterior shoulder pain. Preliminary US evaluations revealed that 129 of 300 (43%) patients had a normal US appearance of the biceps tendon; 110 (36.6%) had tendinosis; 13 (4.3%) had tenosynovitis; 31 (10.3%) had both tendinosis and tenosynovitis; 8 (2.7%) had a biceps tendon tear; and 9 (3%) had a history of a tenodesis. Of 81 patients who had pain relief after the injection, 41 had a normal tendon appearance on US, and 40 had an abnormal US appearance.

CONCLUSIONS

A large minority of patients with anterior shoulder pain clinically suspected to be due to the biceps tendon have a normal-appearing tendon and sheath. This should not dissuade the operator from performing the procedure.

Clinical indications for image-guided interventional procedures in the musculoskeletal system: a Delphi-based consensus paper from the European Society of Musculoskeletal Radiology (ESSR)-part I, shoulder

BACKGROUND

Image-guided interventional procedures around the shoulder are commonly performed in clinical practice, although evidence regarding their effectiveness is scarce. We report the results of a Delphi method review of evidence on literature published on image-guided interventional procedures around the shoulder with a list of clinical indications.

METHODS

Forty-five experts in image-guided musculoskeletal procedures from the ESSR participated in a consensus study using the Delphic method. Peer-reviewed papers regarding interventional procedures around the shoulder up to September 2018 were scored according to the Oxford Centre for Evidence-based Medicine levels of evidence. Statements on clinical indications were constructed. Consensus was considered as strong if more than 95% of experts agreed and as broad if more than 80% agreed.

RESULTS

A total of 20 statements were drafted, and 5 reached the highest level of evidence. There were 10 statements about tendon procedures, 6 about intra-articular procedures, and 4 about intrabursal injections. Strong consensus was obtained in 16 of them (80%), while 4 received broad consensus (20%).

CONCLUSIONS

Literature evidence on image-guided interventional procedures around the shoulder is limited. A strong consensus has been reached for 80% of statements. The ESSR recommends further research to potentially influence treatment options, patient outcomes, and social impact.

KEY POINTS

• Expert consensus produced a list of 20 evidence-based statements on clinical indications of image-guided interventional procedures around the shoulder. • The highest level of evidence was reached for five statements. • Strong consensus was obtained for 16 statements (80%), while 4 received broad consensus (20%).

Ultrasound-guided interventions for painful shoulder: from anatomy to evidence

Shoulder pain is a common musculoskeletal disorder of variable etiology, ranging from rotator cuff pathology to peripheral nerve entrapment. Advances in ultrasound (US) technology have allowed static and dynamic evaluation of shoulder problems and most importantly, offer real-time, radiation-free guidance for interventions. The present review aims to describe shoulder anatomy in detail using information from cadaveric models and to illustrate US-guided techniques using clearly labeled figures and videos. The review will also present evidence of specific US-guided therapies for shoulder pain by summarizing landmark studies, systematic reviews, and meta-analyses. The following shoulder structures will be covered: 1) the biceps long head tendon, 2) the acromioclavicular joint, 3) the subacromial-subdeltoid bursa, 4) the glenohumeral joint, 5) the suprascapular nerve, and 6) the axillary nerve.

Arthrographic Anatomy of the Biceps Tendon Sheath: Potential Implications for Selective Injection

The purpose of this investigation was to better define the anatomical features of the biceps tendon sheath, including the distance the sheath extends below the inferior margin of the subscapularis tendon and below the termination of the bony bicipital groove. A total of 110 magnetic resonance and computed tomography arthrograms performed during 1-year period at our institution were retrospectively reviewed, and the length of the biceps tendon sheath and distances from the inferior margin of the subscapularis tendon and from the termination of the bicipital groove to the inferior margin of the biceps tendon sheath were measured by 3 radiologists. The mean length of the biceps tendon sheath was 47.5mm. The mean distances from the inferior margin of the subscapularis tendon and from the inferior margin of the bicipital groove to the distal extent of the biceps tendon sheath were 24.5mm and 11.9mm, respectively. The relationships among these 3 anatomical measurements and biological confounders of sex and age were investigated while controlling for measurement variability. The anatomical relationships between the biceps tendon sheath and surrounding structures may have implications for needle placement when attempting to inject into the biceps tendon sheath for diagnostic or therapeutic purposes.
