Summary

The goal of this randomized clinical trial is to compare two surgical techniques used for skin coverage after surgical correction of camptodactyly, a condition in which one or more fingers remain bent and cannot be fully straightened. The study will include children and adolescents with camptodactyly who have a proximal interphalangeal joint flexion contracture of 30 degrees or more and an indication for surgical treatment.

The main question the study aims to answer is:

\- Does a radial longitudinal flap provide better gain and maintenance of finger extension six months after surgery compared with a full-thickness skin graft?

The study will also evaluate:

* Movement of the affected finger;
* Recurrence of the deformity;
* Surgical complications;
* Hand function;
* Patient and/or parent or caregiver satisfaction;
* Adherence to rehabilitation and nighttime splint use;
* Overall surgical outcome.

Researchers will compare radial longitudinal flap and full-thickness skin graft to determine whether the radial longitudinal flap provides better maintenance of finger correction.

Participants will:

* Undergo the surgical treatment indicated for camptodactyly, with skin coverage using either a radial longitudinal flap or a full-thickness skin graft, according to randomization;
* Be evaluated before surgery and at 2, 4, 8, and 12 weeks and 6 months after surgery;
* Have movement of the affected finger assessed using standardized goniometry;
* Follow the postoperative rehabilitation protocol, including occupational therapy and nighttime extension splint use;
* Complete assessments of hand function and satisfaction at the scheduled evaluation periods.
* Approximately 42 eligible fingers will be randomized, with 21 fingers allocated to each treatment group. If a participant has more than one eligible finger, each eligible finger may be randomized independently.

Conditions

  • Camptodactyly

Interventions

PROCEDURE

Radial Longitudinal Flap

Surgical coverage of the skin defect created after standardized release of the contracted structures in patients with camptodactyly, using a radial longitudinal flap raised from the radial aspect of the affected finger and transposed to cover the resulting volar defect.

PROCEDURE

Full-Thickness Skin Graft

Surgical coverage of the skin defect created after standardized release of the contracted structures in patients with camptodactyly, using a full-thickness skin graft. The graft will be harvested from the wrist flexion crease or hypothenar region according to the standardized surgical protocol.
