Study of Fingertip Reconstruction Using Cross Finger Flap and FTG

Abstract

Objectives: Fingertip injuries are frequent and there are many techniques used for reconstruction fingertip injuries. The authors reviewed the outcomes of fingertip reconstruction, including sensation and shape, using the combined technique of the cross-finger flap and full thickness skin graft and defined the optimal dimensions of fingertip defect that is applicable to this technique. Between 2019 and 2021, 40 cases, aged 3-60 years (mean, 28.1 years), who hadMethods: undergone fingertip reconstruction using a combination of the cross-finger flap and full thickness skin graft were reviewed. The presence of fingertip and nail deformity and the results of the Semmes-Weinstein (S-W) monofilament and static two-point discrimination tests were analyzed. Fingertip deformities were noted in 12 cases whereResults: the defect was more than 50% of the Tamai zone I or extended to zone II. Mild nail plate deformity was found in 12 cases with more than 40% of the nail bed defect. 8 out of these 12 cases presented with partial phalangeal tuft defects. 32 fingers were examined using the Semmes-Weinstein test, and their scores were between 2.83 and 4.31 in 20 fingers and 4.56 in 12 fingers. 24 were examined for static two-point discrimination, with 5 mm in 12, 6 mm in 4, and 10 mm in 2. The color and contour of all donor fingers were almost typical. The combination of the cross-finger flap andConclusions: full-thickness full thickness skin graft is applicable to around 50% of fingertip defect within the Tamai zone I, achieving a satisfactory shape and regaining more than protective sensation.
