Paediatric Post Burn Flexion Contracture Release: Early Outcomes Using Two Bloodless Techniques.

Abstract

Post burn flexion contracture of the hand in children constitutes a significant proportion of post burn complications. We compared the early clinical outcomes of reconstruction of pediatric post burn flexion contracture of the digits of the hand using tourniquet or tumescent technique. A prospective randomised study of pediatric patients requiring contracture release and wound resurfacing with full thickness skin graft between September 2020 and August 2021. Patients were randomised into groups of either tourniquet or tumescent technique for contracture release. The surface area of graft take and total active motion across joints were the outcome measures. Student t-test, and Chi-squared test were performed. Twenty-two (22) patients were randomised into either group. The mean age of the participants was 6.09 ± 2.41 years, mostly males 31 (72.1%). A grade three (3) flexion contracture was the most common (72.1%). Ninety four (94) digits and one hundred and seventy eight (178) joints were operated on with the proximal interphalangeal joint (PIPJ) being the most common (48.9%). The mean surface area of graft take on post operative day ten (10) was significantly higher for the tumescent group than the tourniquet group, p =0.001. The total active motion across the joints at six (6) and nine (9) weeks post operative showed a strong correlation between the total active motion across joints and the technique of release, p=0.004 and 0,001 respectively. Tumescent technique is a feasible alternative to the tourniquet method for post burn flexion contracture release of the digits in the pediatric burned hand.
