Conclusion
De Quervain tenosynovitis is a condition that can be treated non-surgically with thumb spica splint, non-steroid anti-inflammatory drugs, physical therapy and corticosteroid injections. Neural therapy is a safe and effective method for the treatment of De Quervain tenosynovitis. To the best of our knowledge, this is the first study to have evaluated the long-term effect of neural therapy in patients with De Quervain tenosynovitis. Nevertheless, there is a need for further studies with larger sample sizes to confirm the widespread application of these results.
