This study aims to assess the feasibility, safety, and accuracy of a robotic arm-assisted carpal tunnel injection in comparison with the conventional ultrasound-guided method, prior to conducting a larger-scale study.
The use of a robotic arm to maintain the ultrasound probe in position could provide valuable assistance to the physician. The procedure would no longer require the involvement of a third person in addition to the physician. To date, no study has compared these two approaches.
Age ≥ 18 and ≤ 75 years.
Clinical diagnosis of carpal tunnel syndrome.
Indication for corticosteroid injection as determined by investigator.
Moderate to severe carpal tunnel syndrome defined by a pain score on the Visual Analogue Scale (VAS) ≥ 4 (at baseline and on day 0).
Known allergy to corticosteroids or povidone-iodine (Betadine)
Probable or ongoing systemic or local infection
History of injection in the affected wrist within the last 6 months
Thenar eminence atrophy
