Versatility and Modifications of the Cross-finger Flap in Hand Reconstruction
Journal Title: INTERNATIONAL JOURNAL OF SCIENTIFIC STUDY - Year 2017, Vol 5, Issue 6
Abstract
One of the most common soft-tissue defects encountered in hand surgery is the soft-tissue defect on the volar aspect of the finger. There are many reconstructive options for such a defect. Starting from full-thickness grafts, which may not be very reliable in providing a stable skin cover, to microvascular flaps such as arterialized venous flap, superficial palmar branch of the radial artery flap, posterior interosseous perforator flap, and ulnar artery perforator free flap, groin flap, venous flap, and toe pulp transfers exist. Need for expertise, inherent technical problems, and unpredictability of survival of these flaps have restricted the use of these microvascular flaps in reconstruction of such defects on the fingers. In such situations, the cross-finger flap still remains as the workhorse flap. The cross-finger flap is an established method of reconstruction of defects on the volar aspect of the fingers. The reason it became popular was because of the technical ease and safety in the harvest and reliability of the flap. However, defects on the finger were not confined only to the volar aspect. Dorsal defects, defects on the stump of the fingers, and defects on the radial and ulnar borders of the fingers were encountered frequently in hand surgery. Furthermore, the adjoining finger was always not available for the harvest of the cross-finger flap. In an effort to make the flap suitable for cover of many different sites of defects on the fingers, many modifications have been made. The modifications included changes in the donor finger, changes in the technique, and changes in the design. This review paper analyzes the different uses of the flap and the modifications made in the technique.
