Comparison of Injection Techniques in Carpal Tunnel Syndrome
Sponsor: Ankara Etlik City Hospital
Summary
The aim of this study is to compare the effects of ultrasound-guided hydrodissection with 5% dextrose and perineural corticosteroid injection on the clinical parameters of carpal tunnel syndrome, as well as to evaluate the long-term efficacy of these treatments.

Conditions
Interventions
5% Dextrose
Ultrasound-guided hydrodissection is performed using a 12 MHz linear transducer (GE Logiq P9, GE Healthcare) via an in-plane ulnar approach under sterile conditions. 2.5 ml of 5% dextrose will be injected via an in-plane ulnar approach to mechanically separate the median nerve from the transverse carpal ligament. Subsequently, an additional 2.5 ml of 5% dextrose will be administered to separate the nerve from adjacent flexor tendons. The total injection volume will be 5 ml.
Betamethasone and local anesthetic
Ultrasound-guided perineural injection is performed using a 12 MHz linear transducer (GE Logiq P9, GE Healthcare) via an in-plane ulnar approach under sterile conditions. A total of 2 ml solution (1 ml betamethasone and 1 ml 2% lidocaine) is injected perineurally around the median nerve under ultrasound guidance at the scaphoid-pisiform level.
