Brief summary
The trial will evaluate the efficacy of DYNAVISC in subjects with a diagnosis of persistent or recurrent carpal tunnel syndrome. This is a prospective, multicenter, randomized, evaluator-blinded clinical trial. Results will be stratified based on the method used for median nerve coverage: Group 1 (standard of care surgery followed by DYNAVISC surrounding the median nerve, n=25 participants), Group 2 (standard of care surgery followed by coverage of the median nerve with a hypothenar fat pad flap, n=25
Detailed description
The trial will evaluate the efficacy of DYNAVISC in subjects with a diagnosis of persistent or recurrent carpal tunnel syndrome. This is a prospective, multicenter, randomized, evaluator-blinded clinical trial. Results will be stratified based on the method used for median nerve coverage: Group 1 (standard of care surgery followed by DYNAVISC surrounding the median nerve, n=25 participants), Group 2 (standard of care surgery followed by coverage of the median nerve with a hypothenar fat pad flap, n=25 participants). All participants will gently mobilize their wrist and fingers immediately following surgery and multiple times daily thereafter. Strenuous movements will be allowed beginning 6 weeks following surgery. Participant's hand will be evaluated at 1 week, 4 weeks, and 12-weeks following surgery. Pain measurement will be recorded by participant using visual analog scale (VAS Score); hand function measurement will be recorded by participant using Disabilities of the Arm, Shoulder and Hand (Quick DASH Score); neuropathic pain will be measured by DN4 Score; median nerve recovery will be measured by electroneuromyography (sensory conduction speed and distal motor latency); and grip strength will be measured by dynamometer. This information will be obtained and recorded at baseline and at evaluations by a person blinded to treatment assignment.
Interventions
DYNAVISC (1 ml) will be applied over/around the median nerve, including repair site, by the surgeon using the applicator provided with the product.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain using VAS | 12 weeks | Change in pain and paresthesia will be determined by recording VAS Scores at baseline and each Visit following surgery up to 12 weeks following surgery. VAS Score is a 1-10 range, with 1 being the best result. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Evaluation of neuropathic pain using DN4 assessment | 12 weeks | Change in neuropathic pain of the hand and fingers following repair of persistent or recurrent carpel tunnel syndrome will be performed by participant's scoring of DN4. |
| Resumption of hand function using the Quick DASH Score. | 12 weeks | Resumption of hand function following repair of persistent or recurrent carpal tunnel syndrome will be measured by participant using the Quick DASH Score. |
| Grip strength of hand closing | 12 weeks | Grip strength of hand closing is measured by participant using a Jamar Hand Dynamometer as recorded in kilogram-force (kgf). |
| Improvement in nerve conduction and lateral deviation | 12 weeks | Change in velocity of nerve conduction and lateral deviation will be measured by Electroneuromyography (ENMG). |
