NCT05503719

Brief Summary

The study compares two widely used treatments in closing the wound after open carpal tunnel release surgery: absorbable and non-absorbable sutures. It is conducted as a randomized controlled trial, where the participants are divided into two research groups. The visual outcome of the scar will be evaluated a year after the surgery.

Outcome Measures

Primary Outcomes (1)

  • Visual outcome (VAS) of the scar (nice and ugly) as evaluated by the patient

    The subjective aesthetics of the scar evaluated by the patient on a 10 cm visual analog scale (VAS) ranging from "the ugliest scar possible" to "the most beautiful scar possible". The proportion of ugly and nice scars will be reported. Outcome will be collected at one year time point.

    1 year

Secondary Outcomes (6)

  • Visual outcome (VAS) of the scar (nice and ugly) as evaluated by an outcomes assessor

    1 year

  • Pain (VAS) experienced by the patient from the sutures

    2 weeks

  • The Boston Carpal Tunnel Questionnaire

    1 year

  • The Net Promoter Score

    1 year

  • Costs

    1 year

  • +1 more secondary outcomes

Study Arms (2)

Absorbable Suture

EXPERIMENTAL

Surgical wounds of this arm will be closed with an absorbable suture.

Procedure: Surgical wound closed with an absorbable suture

Non-absorbable suture

ACTIVE COMPARATOR

Surgical wounds of this arm will be closed with a non-absorbable suture.

Procedure: Surgical wound closed with a non-absorbable suture

Interventions

Patients undergoing median nerve release surgery will get their surgical wound closed with an absorbable suture according to their respective study group.

Absorbable Suture

Patients undergoing median nerve release surgery will get their surgical wound closed with a non-absorbable suture according to their respective study group.

Non-absorbable suture
