US-guided percutaneous release of the first extensor tendon compartment using a 21-gauge needle in de Quervain's disease: a prospective study of 35 cases

A new high-frequency ultrasound classification of De Quervain tenosynovitis

PURPOSE

This study aimed to introduce a new high-frequency ultrasound classification of De Quervain tenosynovitis based on a large group of patients. Detailed characteristics of classification are also reported.

METHODS

From January 2014 to February 2024, patients diagnosed with De Quervain tenosynovitis were retrospectively reviewed. High-frequency ultrasound (7-14 MHz) scanning was performed to identify the anatomy of the extensor pollicis brevis and abductor pollicis longus tendons, presence of intertendinous septa, and pathologic changes. The affected wrist was compared to the contralateral wrist.

RESULTS

453 patients were included: 65 male and 388 female; mean age, 46 ± 27 years (range, 24-65 years). Symptom duration was 14 ± 27 weeks. Disease types were type 0 (n = 5), type 1 (n = 195), type 2a (n = 72), type 2b (n = 18), type 2c (n = 50), type 3 (n = 59), type 4 (n = 45), and type 5 (n = 9). Mean retinacular thickness was 2.1 ± 0.5 mm in affected wrists and 0.4 ± 0.1 mm in contralateral wrists (p < 0.01). The intercompartmental septum was significantly thicker on the affected side (1.2 ± 0.7 mm) than on the asymptomatic side (0.1 ± 0.4 mm) (p < 0.01).

CONCLUSIONS

This novel classification provides detailed ultrasonographic characteristics of De Quervain tenosynovitis, based on a large population of patients. It may help in selecting treatment and predicting outcome. However, relevance and therapeutic significance remain to be demonstrated.

LEVEL OF EVIDENCE

Three-Month Complication Rate of Ultrasound-Guided Soft Tissue Surgical Procedures Across Six Sports Medicine Clinics

OBJECTIVES

To 1) determine the types and frequency of complications within 3 months following ultrasound-guided surgical procedures, and 2) identify any patient demographics, co-morbidities, or procedural characteristics that were associated with an increased risk of complications.

METHODS

A retrospective chart review was performed at six Sports Medicine clinics across the United States. The Clavien-Dindo classification was used to categorize procedural complications on a 5-point scale from 1, representing any deviation in post-procedure care without requiring pharmacological or invasive treatment to 5, representing death. Generalized Estimating Equations for binomial outcomes with a logit link were used to estimate the overall and procedure-specific 3-month complication rates.

RESULTS

Among 1902 patients, 8.1% (n = 154) had diabetes and 6.3% (n = 119) were current smokers. The analysis included 2,369 procedures, which were performed in either the upper extremity (44.1%, n = 1045) or lower extremity (55.2%, n = 1308) regions. The most common procedure was ultrasound-guided tenotomy (69.9%, n = 1655). Additional procedures included, trigger finger release (13.1%, n = 310), tendon scraping (8.0%, n = 189), carpal tunnel release (5.4%, n = 128), soft tissue release (2.1%, n = 50), and compartment fasciotomy (1.6%, n = 37). Overall, there was a complication rate of 1.2% (n = 29 complications; 95% CI: 0.8-1.7%). Individual procedures had complication rates that ranged from 0 to 2.7%. There were 13 Grade I complications in 13 patients, 12 Grade II complications in 10 patients, 4 Grade III complications in 4 patients, and 0 Grade IV or V complications. No associations between complication risk and any patient demographics (age, sex, BMI), co-morbidities (diabetes, smoker), or procedure characteristics (type, region) were identified.

CONCLUSION

This retrospective review provides an evidence-based estimate supporting the low level of risk associated with ultrasound-guided surgical procedures for patients from a variety of geographical settings who are seeking care at private and academic-affiliated clinics.

Tendon injections - upper extremity

Imaging-guided tendon procedures aim to reduce pain and increase function by controlling inflammation and stimulating healing. Ultrasound is the preferable guiding modality due to its high resolution and real-time demonstration of the tendinous anatomy and needle positioning. The technique includes appropriate patient positioning, which varies depending on the targeted tendon, as well as sterile and proper draping. For most procedures, we prefer the "in-plane" approach, which demonstrates the entire needle as it advances through different tissue layers. Upper limb injections commonly use corticosteroids and anesthetics with different reported short- and long-term results depending on the tendon treated; better results are obtained in the treatment of tenosynovitis (sliding tendons such as trigger finger and De Quervain's tenosynovitis). Shoulder and elbow tendinopathies (anchor tendons) may also benefit from injections containing irritants or healing stimulants such as dextrose (prolotherapy) and platelet-rich plasma or by the stimulation of healing via tendon perforations (fenestration). The hyaluronic acid injection has also been used in the treatment of both tenosynovitis and tendinopathies. For tendons passing through osteofibrous tunnels, an additional release may be performed, and the techniques are discussed in this review. Therefore, this article provides practicing musculoskeletal radiologists and trainees with a comprehensive review of tendon injection musculoskeletal image-guided procedures.

A Retrospective Case Series Study on a Minimally Invasive Ultrasound-Guided First Dorsal Compartment Release Technique for Refractory De Quervain Tenosynovitis

OBJECTIVE

The aim of this study was to evaluate the outcomes of patients treated with a novel minimally invasive complete release of the first dorsal compartment percutaneously under ultrasound guidance using an 18-gauge needle with an 18 blade at the tip.

DESIGN

This was a retrospective case series. Nine adults (ten wrists) were included in the study of this technique. All patients had failed conservative care and had tenderness to palpation over the first dorsal compartment, a positive Finklestein test, and confirmed tenosynovitis with ultrasound imaging before the procedure. The main outcome measures were reduction in pain as determined by the numeric rating scale and improvement of function determined by the Nirschl Phase scale at both short- and long-term follow-up.

RESULTS

There was 100% follow-up, with mean (SD) follow-up occurring at 23.1 (9.8) mos (range, 9-42 mos). From preprocedure to follow-up, numeric rating scale pain decreased from 4.1 (SD, 2.5) to 0.0 (SD, 0.0) ( P < 0.001), and Nirschl phase improved from 2.5 (SD, 1.9) to 0.2 (SD, 0.4) ( P = 0.03). No patients required revision open-release surgery or suffered neurovascular complications.

CONCLUSION

This technique resulted in significant improvement of pain and function for all patients and no short- or long-term neurovascular complications were seen.

The ultrasound-guided percutaneous release technique for De Quervain's disease using an acupotomy

Background

This study aimed to compare the effectiveness and safety of the percutaneous first extensor compartment performed by acupotomy procedure with or without ultrasonic (US) guidance.

Methods

The percutaneous release was performed with an acupotomy on 40 wrists of cadavers, which was divided into US guidance operation and blind operation. Each arm was dissected and assessed regarding the amount of release and the extent of neurovascular and tendon injury. An analysis of finite biomechanical elements based on wrists specimen data is analyzed to observe the stress of the first extensor tendon compartment. A prospective study observed the pain visual analogue score(VAS) and Patient-Rated Wrist Evaluation (PRWEB) changes after the ultrasound guidance or blind acupotomy treatment in 30 dQD patients.

Results

The success rate in the ultrasound-guided technique was 85%, and the blind technique was 70% in the cadaver study, both techniques without neurovascular injury. There was no statistically significant difference between the two groups in measuring the distance from the incision marks to the blood vessels and nerves (P > 0.05). According to the biomechanical analysis, the tendon friction rubs when the wrist is upright. When the wrist is flexed, the tendon and tendon sheath is stressed in the bone ridges. In this prospective study, both ultrasound guidance and blind acupotomy treatment achieved well improvements in pain and function (P < 0.05), but the results with no statistically significant between groups (P > 0.05).

Conclusion

Both blind and US-guided percutaneous release by acupotomy of the first extensor tendon compartment can get a good result. US-guided techniques can improve the success rate during acupotomy operations, especially for beginners and followers.

Percutaneous Release of the First Extensor Tendon Compartment in De Quervain's Disease by Acupotomy with US-Guidance: A Cadaveric Study

Background

De Quervain's disease is a painful stenosing tenosynovitis of the first dorsal compartment of the hand affecting the tendons of the abductor pollicis longus and extensor pollicis brevis. This study aimed to evaluate the safety and efficacy of percutaneous first extensor compartment releases performed on embalmed cadaveric models by acupotomy operation with or without US guidance.

Methods

Percutaneous release was performed with an acupotomy on 59 wrists of cadavers; 23 wrists were operated with US guidance, and 39 wrists were operated without US guidance. Each arm was dissected and assessed regarding the amount of release as well as the extent of neurovascular and tendon injury. Anatomical structures were also observed in this study.

Results

Twenty cases (87%) were successfully released with ultrasound-assisted techniques, and 27 cases (75%) were successfully released with blind techniques. No neurovascular injury occurred in any arm, regardless of technique. No significant tendon injury was seen in any arm. Although minor surface scratches were visualized in 11 cases, they occurred in 3 cases (13.04%) with ultrasound assistance and in 8 cases (22.22%) with blind techniques. There was no statistically significant difference between the two groups in the measurement of the distance from the incision marks to the blood vessels and nerves. A fibrous septum and bony protrusions were found in the first dorsal compartment, which may be anatomical factors affecting the success of treatment.

Conclusion

Both traditional and US-guided percutaneous release by acupotomy of the first extensor tendon compartment can be performed for all wrists. US-guided techniques can improve the success rate and reduce damage during acupotomy operations.

Utility of Ultrasonography and Significance of Surgical Anatomy in the Management of de Quervain Disease: A Systematic Review and Meta-Analysis

BACKGROUND

The role of ultrasound in plastic surgery practice has grown significantly over the past decade, with notable applications for conditions of the upper extremity. Its utility for the management of de Quervain disease, however, remains to be established, and the prevalence of first dorsal compartment anatomical variations needs to be adequately assessed.

METHODS

A systematic review was performed to evaluate the role of ultrasound in the diagnosis, anatomical characterization, and clinical management of de Quervain disease. A meta-analysis was conducted to establish the prevalence of first dorsal compartment anatomical variations in the de Quervain disease and general population, along with the diagnostic accuracy of ultrasound for their detection. Outcomes were documented and compared to alternative treatment options.

RESULTS

Extensor retinaculum thickening, tendon sheath swelling, peritendinous edema, and tendon enlargement were the most common sonographic features of de Quervain disease. The prevalence of an intercompartmental septum in the de Quervain disease surgical population was shown to be significantly greater than in the general cadaveric population (67 percent versus 35 percent, respectively). Although the efficacy of energy-based therapeutic ultrasound remains elusive, ultrasound-guided corticosteroid injections were shown to be more accurate than manual injections (90 to 100 percent versus 40 to 100 percent), and to confer significantly better treatment outcomes (73 to 100 percent versus 59 to 83 percent success rates, respectively).

CONCLUSIONS

Ultrasound use is essential to achieve the best evidence-based outcomes in the management of de Quervain disease. The varied prevalence of first dorsal compartment anatomical variations and high accuracy of ultrasound for their detection carry significant prognostic implications.

Management of de Quervain Tenosynovitis: A Critical Analysis Review

»

Most cases of de Quervain tenosynovitis can be managed with nonoperative measures, and the mainstay of treatment is corticosteroid injection (CSI). The use of ultrasound may improve the accuracy of injections and can help to identify and localize injections to separate subcompartments.

»

For patients who are in the third trimester of pregnancy or breastfeeding, there is no contraindication to CSI as studies have shown that it can provide optimal symptomatic relief to the mother without impacting the baby.

»

When nonoperative treatment is unsuccessful, surgical release of the first dorsal compartment (FDC) can provide excellent symptom relief. Open release performed through a longitudinal incision allows for better visualization of the underlying anatomy, resulting in fewer injuries to underlying structures and a lower incidence of hypertrophic scarring compared with a transverse incision.

»

For surgeons who are comfortable performing endoscopic techniques, endoscopic FDC release can result in quicker symptom improvement, superior scar cosmesis, and a lower incidence of radial sensory nerve injury.

»

Studies have shown that FDC release can safely and effectively be performed using the WALANT (wide-awake local anesthesia no tourniquet) technique, which has the potential for cost savings without compromising quality or patient comfort.

Ultrasound-guided musculoskeletal interventional procedures around the elbow, hand and wrist excluding carpal tunnel procedures

Ultrasound is a fast, reliable and radiation-free method for the assessment of a wide range of pathological conditions, as well as for the guidance of percutaneous interventional procedures around the elbow, hand and wrist. Intraarticular and periarticular interventional procedures can be easily performed under continuous ultrasound monitoring to ensure correct needle positioning and medication delivery to a specific target. The most common ultrasound-guided procedures performed around the elbow, wrist, and hand are described in this review, excluding carpal tunnel procedures. Specifically, elbow steroid injections are performed in patients with inflammatory disorders, while hyaluronic acid can be administered in case of osteoarthritis. Septic olecranon bursitis requires percutaneous drainage for diagnosis and appropriate treatment. Dry needling and injection of regenerative medications, such as blood derivatives, are among the treatment options for lateral epicondylosis. Steroid injections are performed to give symptom relief in patients with ulnar neuropathy at the elbow. Hand and wrist steroid injections are performed in case of osteoarthritis, subsequently followed by hyaluronic acid injections, and in inflammatory disorders. Wrist ganglia can be safely aspirated and injected with steroids under ultrasound guidance. De Quervain’s tenosynovitis and trigger finger are chronic tenosynovitides of the wrist and digits, respectively, which can be treated with steroid injections, subsequently followed by hyaluronic acid injections. In conclusion, proper knowledge of the musculoskeletal disorders around the elbow, hand and wrist, as well as US-guided treatment options and operator training, are prerequisites to achieve good outcomes.

Back to the roots of rheumatology - Imaging of regional pain syndromes

Musculoskeletal regional pain syndromes (RPS) often lead to patient referrals in general and rheumatological practice. Detailed history taking and clinical examination can, in most cases, reveal the cause for pain and direct the subsequent management of the conditions. Yet, when in doubt, imaging methods, such as ultrasound (US) may support the clinical assessment. This paper reviews the underlying pathologies of some of the most frequently encountered RPS and the role of musculoskeletal US imaging for their diagnosis and treatment. If available, data on diagnostic accuracy and comparisons with gold standards are reported. The article stresses the importance of anatomical and sonoanatomical knowledge for the proper interpretation of the US images, points out the advantages and disadvantages of this imaging tool, and suggests the future research agenda.

Can Ultrasonography Be Useful in Planning Surgery for De Quervain Tenosynovitis?: A Prospective Study With Emphasis on Detection of the Superficial Radial Nerve and Dominant Pathologic Tendon

OBJECTIVES

We performed preoperative ultrasonography (US) to detect the anatomic course of the superficial radial nerve (SRN) and dominant pathologic tendon of the first extensor compartment in de Quervain tenosynovitis.

METHODS

We prospectively studied 27 patients (29 wrists) with de Quervain tenosynovitis who underwent surgical release of the first extensor compartment. Preoperatively, US was performed to evaluate the presence of the dominant pathologic tendon and the septum in the subcompartment, number of SRNs in the area of the surgical incision, and anatomic running course of the SRN. These variables were also checked intraoperatively. Cohen κ statistics were calculated to investigate agreement between US and surgical field findings.

RESULTS

There were 7 men and 20 women (mean age, 47.8 years; range, 26-67 years). For the dominant pathologic tendon, there were 2 cases (6.9%) of an abductor pollicis longus, 11 cases (37.9%) of an extensor pollicis brevis, and 16 cases (55.2 %) of a nondominant tendon (κ = 0.94). For the subcompartment, there were 10 cases (34.5%) without a septum, 8 (27.6%) with an incomplete septum, and 11 (37.9%) with a complete septum (κ = 0.95). Most SRNs crossed over the first extensor compartment (κ = 0.78).

CONCLUSIONS

Preoperative US can be useful in detecting the anatomic running course of the SRN and dominant pathologic tendon before surgery for de Quervain tenosynovitis. Classifying the anatomic course of the SRN could be essential to planning surgery, and it could be helpful to prevent injury of the SRN during surgery.

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 II, elbow and wrist

BACKGROUND

Although image-guided interventional procedures of the elbow and wrist are routinely performed, there is poor evidence in the literature concerning such treatments. Our aim was to perform a Delphi-based consensus on published evidence on image-guided interventional procedures around the elbow and wrist and provide clinical indications on this topic.

METHODS

A board of 45 experts in image-guided interventional musculoskeletal procedures from the European Society of Musculoskeletal Radiology were involved in this Delphi-based consensus study. All panelists reviewed and scored published papers on image-guided interventional procedures around the elbow and wrist updated to September 2018 according to the Oxford Centre for Evidence-based Medicine levels of evidence. Consensus on statements drafted by the panelists about clinical indications was considered as "strong" when more than 95% of panelists agreed and as "broad" if more than 80% agreed.

RESULTS

Eighteen statements were drafted, 12 about tendon procedures and 6 about intra-articular procedures. Only statement #15 reached the highest level of evidence (ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement). Seventeen statements received strong consensus (94%), while one received broad consensus (6%).

CONCLUSIONS

There is still poor evidence in published papers on image-guided interventional procedures around the elbow and wrist. A strong consensus has been achieved in 17/18 (94%) statements provided by the panel on clinical indications. Large prospective randomized trials are needed to better define the role of these procedures in clinical practice.

KEY POINTS

• The panel provided 18 evidence-based statements on clinical indications of image-guided interventional procedures around the elbow and wrist. • Only statement #15 reached the highest level of evidence: ultrasound-guided steroid wrist injections result in greater pain reduction and greater likelihood of attaining clinically important improvement. • Seventeen statements received strong consensus (94%), while broad consensus was obtained by 1 statement (6%).

Tendoscopic versus open release for de Quervain's disease: earlier recovery with 7.21 year follow-up

Purpose

To compare the time return to work and long-term results of tendoscopic versus open technique for de Quervain’s disease.

Methods

From 2005 to 2013, either tendoscopic or open decompression was performed on 56 consecutive patients (56 wrists) with symptomatic de Quervain’s disease despite a minimum of 3 months non-operative treatment. Of the 50 patients who met the inclusion criteria, 41 patients were followed-up for a mean of 7.21 years postoperatively. Among these 41 wrists, 20 underwent tendoscopic release (group A), and 21 underwent open release (group B). The clinical evaluations were performed preoperatively, 1 month postoperatively and at last follow-up visit, using visual analog scale (VAS); the Disabilities of the Arm, Shoulder and Hand (DASH) Outcome score; and the Finkelstein’s test. The Patient and Observer Scar Assessment Scale (POSAS) was used as an esthetic evaluation tool of the scar at last follow-up.

Results

No significant baseline differences were found between two groups. The average time return to work in group A was less than in group B (P < 0.05), The mean VAS and DASH scores improved significantly in both groups at 1 month and last follow-up visit (P < 0.001). At 1 month, the scores in group A were significantly better than in group B (P < 0.05 and P < 0.001, respectively). There was no difference between groups at last follow-up. In addition, the improvement of the mean DASH score was significantly greater in group A than in group B (34.74 ± 10.99 in group A and 23.58 ± 12.01 in group B, P < 0.01) at 1 month. For POSAS scale, both the OSAS and PSAS scores were significantly better in group A. One patient in group A had cephalic vein injury and 3 patients in group B was involved with radial sensory nerve injury. All patients showed negative on Finkelstein’s test at last follow-up.

Conclusions

The results of this study suggest that tendoscopic technique for de Quervain’s disease could provide earlier symptom relief and earlier recovery with fewer complications and more desirable scar, as well as equivalent successful long-term outcome, when compared with traditional open release technique.

Ultrasound-Guided First Dorsal Compartment Release for Refractory de Quervain Tenosynovitis: A Case Report

De Quervain tenosynovitis is an overuse syndrome associated with inflammation of the tendons in the first dorsal compartment of the wrist. Management includes activity modification, splinting, and corticosteroid injections. In refractory cases, surgical release may be performed, which may be complicated by incomplete release, tendon subluxation, or radial nerve injury. Alternatively, ultrasound-guided release may improve patient satisfaction and outcomes through faster recovery time as well as improved visualization of subcompartments and neurovascular structures. To the best of the authors' knowledge, this is the first case in the literature describing a novel technique for ultrasound-guided first dorsal compartment release for refractory de Quervain tenosynovitis.
