NCT07175675

Brief Summary

The goal of this interventional study is to find out whether conservative treatment with semi-occlusive film is superior to surgical treatment in single finger amputations in adult population. The main question it aims to answer is: Is PRWHE (Patient Reported Wrist and Hand Evaluation) total score measured at 12 months after injury better in conservatively or operatively treated patients?

Outcome Measures

Primary Outcomes (1)

  • PRWHE

    Our primary outcome measure is PRWHE mean difference (MD) between treatment arms in each stratum with the associated 95% confidence interval (CI) at 12 months post-randomization. Patient-Reported Wrist and Hand Evaluation (PRWHE) was chosen, because it covers both pain and loss of function which are the main symptoms after a digital amputation, has evidence of reliability, validity and responsiveness in hand and wrist trauma population, and is considered slightly more responsive than DASH. As a patient reported outcome, it is prone to ascertainment bias - especially since in this study setting it is not possible to blind the participant to given treatment. To overcome this, we have included several objective outcome measures as secondary outcomes. Nevertheless, Patient-Reported Outcome Measures are considered the most meaningful instruments for outcome evaluation in musculoskeletal conditions, because those assess patient-perceived important symptoms and disability.

The film is placed on a cleansed wound surface. bone is shortened to the level of injury. Visible nerves, arteries and tendons are cut and allowed to retract. The film is to be changed once weekly until the wound has closed.
