Macrodactyly是一种严重且罕见的疾病，被认为是最难以治疗的病症之一。没有规则，每个病人的治疗必须是量身定制的，取决于宏观的位置和程度。虽然截肢是成年患者的有效选择，指甲保存和重建是重要的，对治疗结果有直接影响，在审美和病人的自尊。我们使用了广泛的，与指甲象限的保留相关的Z形指尖皮瓣，骨缩短和远端指间关节固定术。通过这种“象限皮瓣”技术，我们获得了良好的功能和美学效果。该技术允许减小手指的大小和体积，并重建指甲复合体和指腹。证据等级：V级（治疗）。
Macrodactyly is a serious and rare disease and considered one of the most difficult pathologies to treat. There is no rule and the treatment for each patient must be tailor-made, depending on the location and degree of macrodactyly. Although amputation is a valid option for adult patients, nail preservation and reconstruction are important and has a direct impact on the treatment outcome, both aesthetically and on the patient\'s self-esteem. We have used a wide, z-shaped fingertip flap associated with the preservation of a nail quadrant, bone shortening and distal interphalangeal arthrodesis. We have obtained good functional and aesthetic outcomes with this \'quadrant flap\' technique. The technique allows decreasing digit size and volume and reconstruction of the nail complex and finger pulp. Level of Evidence: Level V (Therapeutic).
