Cutaneous functional units prediction in outcomes of early and intensive splinting following palmar burn injury in young children: a prospective study.

Background: Palmar burn injuries are common in young children and can result in contracture.
Methods: A prospective longitudinal study describes outcomes of palm and digit extension splint use following burn in 75 children (83 hands) aged < 5 years and determines whether specific cutaneous functional units (CFUs) are associated with early signs of contracture (ESC). Outcomes were assessed up to 9-18 months following burn. Routine clinical data was collected at therapy reviews.
Results: Children were splinted > 12 h/day for a mean of 158 days following burn. The mean time to splint cessation was 264 days following burn. Fourteen hands developed ESC (17%): 12 hands had full ROM restored following conservative management, 2 hands (3%) progressed to contracture. Hands that developed ESC had greater healing time (p = 0.002), greater number of CFUs affected (p < 0.001), and greater number of immediate first webspace and extended first webspace CFUs affected (p = 0.002, p < 0.001 respectively). ESC risk increases for each day to heal (odds ratio [OR] 1.1, 95% CI 1.0-1.2) and each CFU in extended first webspace (OR 2.8, 95% CI 1.5-5.0).
Conclusion: Early and intensive splinting following palmar burn results in excellent ROM. Burns involving more CFUs or the first webspace are associated with ESC.
