Four cases are described in which the opposite ring finger was used for finger reconstruction in transmetacarpal hand amputations. Thumb reconstruction was required in three of these four cases. This was achieved by hallux transfer, tube pedicle combined with an innervated first foot web neurovascular free flap, and second toe transfer respectively. In the fourth case, where a thumb was not required, double finger reconstruction was performed by the use of a second toe combined with a ring finger. This case highlights the limitations of the second toe for finger reconstruction, particularly in achieving palmar-digital grip. The advantages of the ring finger are length and mobility, especially sophisticated intrinsic muscle movement, sensory capacity, strength, wider span, and esthetic excellence.
本文描述了4例经掌骨手部截肢后使用对侧环指进行手指重建的病例。这4例中有3例需要进行拇指重建，分别通过拇趾移植、带蒂皮管联合带神经支配的第一足蹼游离皮瓣以及第二足趾移植完成。在第4例中，由于不需要拇指，故采用第二足趾联合环指进行双指重建。该病例突出了第二足趾用于手指重建的局限性，尤其是在实现掌指抓握方面。环指的优点包括长度、活动度，特别是复杂的内在肌运动、感觉功能、力量、更大的跨度以及美观性。
