The thumb plays an important role in the function of the hand. Sensate reconstruction of the pulp is important in restoring function to the thumb. The aim of this study is to present outcomes of a sensate islanded first dorsal metacarpal artery (FDMA) flap used for the reconstruction of skin defects of the thumb. Patients who had a FDMA flap reconstruction of thumb pulp defects in the orthopaedics and traumatology clinic of affiliated hospital were included in the study. This included eight thumbs of eight patients. The range of motion, sensation and cosmetic satisfaction in the donor and recipient areas were evaluated at a minimum of 2-year follow-up. There were no partial or complete flap failures. The mean static 2-point discrimination was 15 mm and the mean Semmes-Weinstein monofilament test score was 3.93. Cortical re-orientation was observed in 65% of patients. Near normal range of motion and Kapandji scores were regained in all patients. Excellent motion and sensory outcomes were obtained following the FDMA flap reconstruction of thumb pulp defects. The donor morbidity of the flap is minimal, and this flap can be considered as one of the primary options for reconstruction of thumb pulp defects. Level V (Therapeutic).
拇指在手的功能中起着重要作用。感觉重建对于拇指功能的恢复很重要。本研究旨在介绍用于拇指皮肤缺损重建的感觉性岛状第一背侧骨间动脉（FDMA）皮瓣的结果。 在附属医院骨科和创伤科接受 FDMA 皮瓣拇指指腹缺损重建的患者被纳入研究。共包括 8 例 8 个拇指。在至少 2 年的随访中，评估供区和受区的运动范围、感觉和美容满意度。 无部分或完全皮瓣失败。平均静态 2 点辨别觉为 15mm，平均 Semmes-Weinstein 单丝试验评分为 3.93。65%的患者观察到皮质重新定向。所有患者均恢复了接近正常的活动范围和 Kapandji 评分。 FDMA 皮瓣重建拇指指腹缺损可获得良好的运动和感觉效果。皮瓣的供区并发症发生率较低，可将该皮瓣视为拇指指腹缺损重建的主要选择之一。 五级（治疗性）。
