The incidence of pediatric treadmill hand friction burns has been increasing every year. The injuries are deeper than thermal hand burns, the optimal treatment remains unclear. This was a retrospective study of children who received surgery for treadmill hand friction burns from January 1, 2015, to December 31, 2019, in a single burn center. A total of 22 children were surveyed. The patients were naturally divided into two groups: the wound repair group (13 patients), which was admitted early to the hospital after injury and received debridement and vacuum sealing drainage initially, and a full-thickness skin graft later; and the scar repair group (nine patients), in which a scar contracture developed as a result of wound healing and received scar release and skin grafting later. The Modified Michigan Hand Questionnaire score in the wound repair group was 116.31 ± 10.55, and the corresponding score in the scar repair group was 117.56 ± 8.85 (p > .05), no statistically significant difference. The Vancouver Scar Scale score in the wound repair group was 4.15 ± 1.21, and the corresponding score in the scar repair group was 7.22 ± 1.09 (p < .05). Parents were satisfied with the postoperative appearance and function of the hand. None in the two groups required secondary surgery. If the burns are deep second degree, third degree, or infected, early debridement, vacuum sealing drainage initially, and a full-thickness skin graft can obviously relieve pediatric pain, shorten the course of the disease, and restore the function of the hand as soon as possible.

Summary Purpose: To present a surgical regimen based on nail morphology for Wassel-Flatt type IVh thumb polydactyly with a floating ulnar digit. Methods: Cases within six years were retrospectively analyzed and followed up for an average of 18 months. Three types of classifications were defined based on nail morphology - ulnar nail dominant type with two subtypes of nail lateral fold symmetric or asymmetric, radial nail dominant type, and equal nail size type. One out of three procedures, on-top plasty ( I ), soft tissue augmentation ( II ), and the combination of the above two ( III ), was performed. The Tada scoring system was used to evaluate the results. Results: Sixty-three thumbs were enrolled, forty-one of better ulnar nail type underwent top transposition, and in cases of asymmetric nail lateral fold subtype, the result of procedure III was better than that of procedure I , thirteen of the radial nail dominant type and nine of equal nail size type both had procedure II . The equal nail size type was the least effective among groups, with an average Tada of four points. Six cases underwent secondary revision surgery. According to the Tada scoring system, the results were excellent in 61, fair in two. Conclusions: Classifications based on the morphology of the nail can guide surgical planning. On-top plasty is suitable for symmetric nail lateral fold subtype. Soft tissue augmentation is ideal for radial nail dominant type and equal nail size type, and the combination of the two procedures is a better option for asymmetric nail lateral fold subtype.
