We report the use of obliquely oriented V-Y advancement pulp flaps to reconstruct 17 consecutive, lateral oblique fingertip traumatic defects over a 2-year period. All flaps survived completely with no bone protuberance, prominent scar or neuroma evident at an average follow-up of 11 months (range 7 to 19). Although there was no incidence of severe hook nail deformities, there were two patients who had residual mild hook nails, two with pulp/nail asymmetries and one with an ingrown nail. The mean static two-point discrimination was 3.6 mm (range 3 to 8) and the mean Semmes–Weinstein monofilament test score 3.9 g (range 2.44 to 4.56). No correlation was found between the flap obliquity angle and sensory test results. We recommend the obliquely oriented V-Y pulp flap as a reliable reconstructive option for the cover of lateral oblique fingertip defects. Level of evidence: IV

We used bipedicle V-Y ‘cup’ flaps to reconstruct 13 consecutive volar oblique fingertip amputations encountered in a nearly 2-year period. All flaps survived completely with no bone protuberance, scarring or neuroma evident at the end of follow-up (mean, 7 months; range 4–13 months). Two of the 13 patients had moderate or severe tenderness, three had moderate or severe cold intolerance and two had noticeable hook nails. There were no significant (≥10°) flexion contracture in the interphalangeal joints. The mean static two-point discrimination score was 4 mm (range 3–6) and the modal Semmes–Weinstein monofilament test score was 3.6 g (range 3.2–4.2). All patients were satisfied with their surgical outcomes. The bipedicle V-Y ‘cup’ flap provides good results in terms of fingertip contour, padding and sensation, and has a low complication rate when used to treat volar oblique fingertip amputations.
