Fingertip injuries remain as one of the most common injuries in the hand. The ideal reconstruction for such injuries is to provide abundant tissue with similar qualities, preserve the length, maintain joint motion and restore fingertip sensation. Although many reconstructive methods are described in the literature, many disadvantages can be associated with these procedures.
An island skin on the side of the proximal phalanx, based on the ipsilateral digital artery, was elevated to resurface the defect of the fingertip. Six male patients with fingertip injuries were treated by using this flap from August 1993 to January 1994. Their ages ranged from 20 to 55 years. The average follow-up time was 8.5 months.
Three of the six flaps were involved the middle fingers; two, for the index fingers and one, for the small finger. The sizes of the flaps varied from 1.5 by 2.0 to 2 by 3;. all the flaps survived. There was no vascular disturbance nor neurological deficit, and no limitation of joint motion. All the patients were pleased with the results.
The advantages of the reverse digital artery island flap include using a single operative field on the injured digit, allowing for treatment of single or multiple fingertip injuries, providing abundant tissue with similar qualities and aesthetic improvement.
指尖损伤仍然是手部最常见的损伤之一。此类损伤的理想重建方法是提供大量质地相似的组织，保留长度，维持关节活动并恢复指尖感觉。尽管文献中描述了许多重建方法，但这些手术可能存在许多缺点。
以同侧指动脉为蒂，掀起近节指骨侧面的岛状皮瓣，用于修复指尖缺损。1993年8月至1994年1月，6例男性指尖损伤患者采用该皮瓣治疗。年龄20～55岁。平均随访时间8.5个月。
6个皮瓣中，3个用于中指，2个用于示指，1个用于小指。皮瓣大小为1.5×2.0至2×3；所有皮瓣均存活。无血管危象及神经损伤，关节活动无受限。所有患者对结果满意。
逆行指动脉岛状皮瓣的优点包括：在损伤手指上采用单一术野，可用于治疗单个或多个指尖损伤，提供大量质地相似的组织并改善美观。
