Evaluation of Effectiveness of Local Anesthetic Injection in Patients With De Quervain Tenosynovitis

De Quervain tenosynovitis is the most common cause of lateral wrist pain. It occurs with stenosis of the abductor pollicis longus and extensor pollicis brevis tendons in the first dorsal extensor compartment of wrist. When these muscles are contracted, thumb extension is observed, so repeated ulnar deviation and thumb extension exacerbates pain. It is seen more commonly in middle-aged females and in the dominant hand. Although it has been shown that fibrous tissue deposits cause thickening of the tendon sheaths, the etiology of de Quervain tenosynovitis is unclear. The prevalence of de Quervain tenosynovitis has been reported to be 0.5% in males and 1.3% in females. Diagnosis of de Quervain tenosynovitis is based on clinical examination. The Finkelstein test is the provocation of pain with wrist ulnar deviation. Plain radiography may be useful for differential diagnosis. Conservative treatment of rest, non-steroidal anti-inflammatory drugs (NSAID), and physical therapy is applied first, then there may be a need for corticosteroid injections, and in resistant cases, surgery. Neural therapy (NT) is a type of regulatory therapy using local anesthesia for the management of chronic musculoskeletal pain. NT includes local therapy (eg,infiltration of trigger points) and segmental therapy (eg, sympathetic ganglia, nerve roots, and peripheral nerves) . To the best of our knowledge, the effect of neural therapy on patients with De Quervain tenosynovitis has not been previously evaluated. Therefore, the aim of this study was to highlight the effect of neural therapy on this condition.
