Radial Longitudinal Flap vs Full-Thickness Skin Graft after camptodactyly correction
Official title: Treatment of Camptodactyly With Radial Longitudinal Flap Versus Full-Thickness Skin Graft: A Randomized, Parallel, Superiority Clinical Trial
Run by Associação de Assistência a Criança Deficiente · NCT07786701 · Data updated 2026-11-12
This trial tests whether using a radial longitudinal flap to cover the skin after camptodactyly surgery helps fingers stay straighter than a full-thickness skin graft in children and teens.

Is this trial a fit for you?
✓Likely a good fit
Children and adolescents with camptodactyly and a PIP joint flexion contracture of 30° or more who need surgical correction.
✕Probably not a fit
Patients with irreversible fixed joint stiffness, prior finger surgery, or syndromic conditions that affect the hand may not benefit from this approach.

What this trial studies
This is a prospective, randomized, parallel-group trial comparing two surgical skin-coverage approaches after correction of camptodactyly. Participants are children and adolescents with a PIP joint flexion contracture of 30° or more who require surgery. Fingers are assigned 1:1 to radial longitudinal flap or full-thickness skin graft, with computer-generated randomization and allocation concealment. Outcomes include finger extension gain and maintenance at six months, range of motion, deformity recurrence, surgical complications, hand function, patient/parent satisfaction, and adherence to rehabilitation. The study aims to determine which technique provides better lasting correction and functional results, potentially guiding postoperative care and tissue coverage choices.
Why it matters
Potential benefit: If successful, the radial longitudinal flap could improve long-term finger extension and hand function after camptodactyly surgery.
How similar studies have gone: Randomized comparisons of local flap and graft techniques have shown variable results; this study tests a specific flap against a graft in camptodactyly, addressing a gap in evidence.
