Palmar crease release and secondary full-thickness skin grafts for contractures in primary full-thickness skin grafts during growth spurts in pediatric palmar hand burns.

Pediatric palmar hand burns are a difficult problem because of the serious hand deformity, with functional impairment resulting from rapid growth. In cases of severe pediatric palmar hand burns, a secondary full-thickness skin graft after a primary full-thickness skin graft offers a reliable way of obtaining the required functional and aesthetic outcomes.This study retrospectively evaluated 28 children who required palmar crease releases and secondary full-thickness skin grafts during the past 12 years. The case records were reviewed for sex and age distributions, injury mechanism, and time interval between the primary and secondary full-thickness skin grafts. Surgical procedures included secondary full-thickness skin grafts and incisional releases of grafted skin on the involved creases. There were 19 men and 9 women. The mean age at the time of the burn injury was 10.1 months (range, 5-19 months). The mean age at the time of the secondary full-thickness skin graft was 8.3 years (range, 3-17 years). The most common mechanism of burn injury was steam (n = 24). The median time interval from the primary to the secondary full-thickness skin graft was 67 months (range, 8-156 months). The number of released creases was 81. The number of palmar web contractures in 23 patients was 52. A secondary full-thickness skin graft was more frequently necessary in patients with a primary full-thickness skin graft in the proximal digital crease and palmar web areas. All patients achieved adequate digital length and palmar web contour after surgery. Our patients should be observed until the rapid pubertal growth period.
