Wound Closure Study in Carpal Tunnel and Trigger Finger Surgery

March 3, 2026 updated by: Peter C. Rhee, Mayo Clinic

Absorbable Versus Non-Absorbable Suture in Carpal Tunnel and Trigger Finger Wound Closure

Does a difference in patient satisfaction and cosmetic outcome exist between wound closure with absorbable or non-absorbable sutures.

Detailed Description

The study will involve randomizing patients to wound closure with absorbable or non-absorbable sutures. We will if scar formation (symptoms and aesthetics) if different between the two types of closures as determined by the patient and observer scar assessment scale version 2.0 (POSAS) and the patient-rated wrist/hand evaluation (PRWHE), between absorbable and non-absorbable suture for wound closure of open carpal tunnel release and trigger finger pulley release.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Scar formation with the Patient and Observer Scare Assessment Scale
Time Frame: 1 year

Blinded scar assessment utilizing the patient and observer scar assessment scale version 2.0 (POSAS).

The POSAS is scored from the perspective of the patient and a blinded observer independently. Scores range from 1 to 10 with 1 indicating normal skin and 10 indicating the worst scar imaginable. The 1 to 10 scoring is performed in 6 domains of various scar characteristics to obtain a total score ranging from 10 to 60. Additionally, there is an overall scar appearance score that ranges from 1 to 10 with 1 indicating normal skin and 10 indicating the worst scar imaginable.
