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.

Ultrasound-guided needle-knife for De Quervain's disease: A protocol for systematic review and meta-analysis

BACKGROUND

De Quervain's disease is a kind of aseptic inflammation caused by repeated frictions of tendons in the tendon sheath of the styloid process of the radius. The main symptoms are protuberance and pain of the styloid process of the radius, accompanied by aggravation of pain during the movement of the wrist and thumb. The advantages of needle-knife are simple operation, obvious therapeutic effect and high safety. It can also be used to treat De Quervain's disease. Ultrasound gives a precise visualization of the thickness. The purpose of this study is to evaluate the efficacy and safety of ultrasound-guided needle-knife in the treatment of De Quervain's disease and to provide the latest basis for clinical application.

METHODS

The computer will be used to search all randomized controlled trials (RCTs) about ultrasound-guided needle-knife treatment of De Quervain's disease in the following database: PubMed, Web of Science, Cochrane Library, Cochrane Central controlled Trials Registry (CENTER), EMBASE, China National knowledge Infrastructure (CNKI), Wanfang data, Chinese Biomedical Literature Database (CBM), VIP Database (VIP). The effectiveness and safety of ultrasound-guided needle-knife in the treatment of De Quervain's disease were evaluated with pain intensity, wrist function as the main index and wrist range of motion, adverse events and quality of life as the secondary index. Revman5.3 software was used for data processing.

RESULTS

This study will provide the latest evidence for the Ultrasound-guided needle-knife for De Quervain's disease.

CONCLUSION

The conclusion of this study is to evaluate the effectiveness and safety of ultrasound-guided needle-knife in the treatment of De Quervain's disease.

Anomalous course and stenosing tenosynovitis of the extensor pollicis longus tendon at the radial styloid process: A case report

RATIONALE

Anomalous course and tenosynovitis of extensor pollicis longus (EPL) tendon is a rare condition that presents clinical symptoms very similar to de Quervain's disease. Herein we report a case of anomalous course and tenosynovitis of the extensor pollicis longus (EPL) tendon associated with symptoms of de Quervain's disease.

PATIENT CONCERNS

A 44-year-old right-handed man visited the clinic because of radial pain associated with the left wrist, which was aggravated during the previous 10 days. The patient tested positive on the Finkelstein's test and displayed a limited range of motion of the left wrist. Motion of the thumb and wrist aggravated pain.

DIAGNOSES

Magnetic resonance imaging (MRI) of the left wrist suggested mild tenosynovitis at the third extensor compartment and intersection syndrome. However, clinical symptoms failed to match the MRI findings.

INTERVENTIONS

A zig-zag skin incision on the radial styloid process was made. The operative findings revealed stenosing tenosynovitis with partial tearing. Retraction of the tendon extended the thumb interphalangeal joint, suggesting that the tendon was the EPL tendon rather than EPB tendon. After operation, we reviewed the MRI of the patient, which revealed that the oblique course of the EPL tendon originated from the ulnar side of the forearm to the radial styloid at the radial and proximal site of Lister's tubercle. No EPB tendon was present.

OUTCOMES

At 12 months of follow-up, the patient's radial styloid process was completely asymptomatic and resumed full daily activities.

LESSONS

Anomalous course of the EPL tendon is rarely reported associated with similar symptoms of de Quervain's disease. However, the knowledge and understanding of this potential anomaly in the course of EPL tendon is very important for the treatment of de Quervain's disease to decrease patient dissatisfaction after surgery.
