Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Collagenase Injection | This procedure will be performed either in a minor procedure room or the hand clinic as per surgeon's routine practice. Collagenase will be administered with or without local anesthesia. As this is a pragmatic study there may be more than one digit injected at a time just as surgery occurs on more than one digit at a time. A recently published study by Gaston et al confirmed that two concurrent injections of collagenase to 2 affected joints in the same hand are generally well tolerated and the frequency of most adverse events (AEs) is similar to those reported in studies that use single sequential injections.~collagenase injection: injection | 0 | 8 | EG000 |
| Group 2 | Limited Palmar Fasciectomy | The Dupuytren's cord will be excised under local anesthesia in a minor procedure room setting or main operating room under local or general anesthetic depending on the complexity of the disease and the surgeon's routine. As this is a pragmatic study comparison of collagenase injections (novel intervention) to limited palmar fasciectomy as it is actually presently performed in all settings academic or community (local in minor room or general/local anesthetic in the main operating room) will be examined. Surgery will be performed according to the operating surgeon's preferred technique i.e. zig-zag Brunner incision or straight incision with z-plasty closure of the skin.~limited palmar fasciectomy: surgery | 0 | 13 | EG001 |
