Long-Term Outcomes of Atasoy Flap in Children With Distal Finger Trauma.

Distal finger trauma is one of the most frequent emergencies in children and has the potential for functional and cosmetic damage to the hand. The Atasoy flap (AF) is a vascularized, subcutaneous pedicle V-Y advancement flap used to cover a loss of distal finger substance. Our hypothesis was that the AF is a safe, reliable flap that results in few complications and gives satisfactory functional and cosmetic results in children. We retrospectively assessed children with distal finger trauma and AF pulp reconstruction in our pediatric orthopedic department between 2008 and 2017. The lesion zone was classified, and we also evaluated necrosis, infection, the shape of the pulp, pulp sensitivity (Weber test), hyponychial scarring, and the presence of a hook nail deformity. Lastly, we compared patients who developed a hook nail with those who did not. Thirty children were included (mean age at trauma, 6.4 years [range, 1.3-15.7 years]). In 21 cases, the finger damage was located in Ishikawa subzone II. No cases of necrosis or infection were reported. Epicritical tactile sensitivity was good in 20 patients (67%). A hook nail deformity was observed in 15 children (50%) and hyponychial scarring in 22 patients (73%). The pulp had a normal shape in 13 children (43%). The hook nail group displayed more hyponychial scarring, greater nail dystrophy, and lower pulp sensitivity. The AF yielded contrasting results. High reliability, good coverage, and minimal donor-site morbidity were compromised by suboptimal tip length/shape, nail appearance, and sensitivity. Therapeutic IV.
