    Abstract:
    The thenar flap is a well-described technique, but reports about its use in patients with multiple fingertip injuries are limited. This study aims to introduce a surgical technique of using an extended thenar flap for two adjacent fingertip amputations and to evaluate the clinical outcomes and related complications. From October 2013 to October 2016, 12 patients (24 fingers) underwent soft tissue reconstruction of two adjacent fingers with an extended thenar flap. At the last follow-up, the patients were assessed for cold intolerance in the reconstructed fingers; two-point discrimination (2PD); range of motion (ROM); functional outcomes using the quick disabilities of the arm, shoulder, and hand (DASH) score; functional and appearance outcomes using the Michigan Hand Outcome Questionnaire (MHQ); and time taken to return to work. The mean follow-up time was 13.5 (range: 12-16) months. All flaps survived. The mean total active ROM in flexion measured at the last follow-up was 255° (range: 245°-260°). Objective sensibility in the flaps was ascertained as an average static 2PD of 6.9 (range: 3-10) mm. The mean quick DASH score was 3.3 (range: 0-9.1). The mean MHQ score was 93.8 (range: 88-100). All patients returned to work within 6.2 weeks on average. There were no complications. The extended thenar flap technique is a good alternative for simultaneous coverage of small-to-large defects in two adjacent fingertips.
