Comparison of Outcomes of V-Y Atasoy vs Pentagonal Advancement Flap in the Management of Fingertip Injuries Allen Type II and III in a Tertiary Hospital

Abstract

Background. Fingertip injuries are the most common traumatic conditions of the hand, affecting productivity and livelihood due to a decrease in manual labor capabilities. The V-Y Atasoy advancement flap is typically effective in managing dorsal or transverse fingertip Allen type II and III injuries but may result in complications like dog ears, flap necrosis, paresthesia, and hook nail deformities. Objective. This paper aimed to describe the assessment, operative technique, and outcomes in patients with fingertip injury Allen type II and type III treated with the V-Y Atasoy advancement flap versus the pentagonal flap. We also aimed to compare the outcomes and complications associated with each technique. Methodology. A randomized controlled trial was done among patients with fingertip injury Allen type II and III who were admitted to a tertiary hospital. Results. There were no significant differences in the rates of immediate complications (flap necrosis, infection, dog ear deformity) or short-term outcomes (two-point discrimination, Semmes-Weinstein monofilament test) between the two groups. Most patients had excellent satisfaction and were able to return to work. Conclusion. Patients of the two groups had good to excellent outcomes and had minimal complications, with no significant differences between the groups. The pentagonal flap can be an alternative to the V-Y Atasoy flap in managing fingertip injuries, especially those with a larger surface area of injury.
