Description
Summary:	Antegrade homodigital neurovascular island flap (AHIF) is one of the methods used in fingertip amputations to cover the defect area, preserve finger length and obtain a painless and sensitive fingertip. The aim of this study was to evaluate the functional and sensory outcomes in patients who underwent AHIF for fingertip amputation and to analyze the relationship between patient satisfaction and outcome measures. Twenty patients with a mean age of 37 (18–63) years were analyzed retrospectively. The patients were evaluated in terms of hook nail development, active interphalangeal joint movements, cold intolerance, and sensory function of the flap covered area. Static two-point discrimination test and Semmes Weinstein monofilament test were performed for sensory evaluation. All flaps survived completely at the end of follow-up (mean, 36 months; range 11–64 months). Five patients had cold intolerance and two had hook nails. In total, proximal interphalangeal or distal interphalangeal joint flexion contracture developed in 25 % of the patients. The mean static two-point discrimination score was 4.6 ± 1.6 (2–8) and Semmes–Weinstein monofilament test score was 3.48 ± 0.6 (2.44–4.17). Subjective satisfaction levels of the patients were found to be high and did not show a statistical relationship with the measured clinical outcome parameters (p > 0.05). Since AHIF contains a solid and continuous neurovascular pedicle, the probability of necrosis and loss of sensation is low in AHIF. In addition, the graft need of the donor area is not high. Its disadvantage is the rate of restriction of joint movements. IV.
