A new design of the cross-finger flap: the C-ring flap.

A new cross-finger flap, the C-ring flap, is described for repair of degloved amputation stumps and dorsal and volar defects of the fingers. The C-ring flap is an axial pattern cross-finger flap based on one digital vascular bundle either distally or proximally. We used this flap in 12 cases with different types of finger defects. The results were satisfactory. We conclude that the C-ring cross-finger flap had distinct advantages over standard cross-finger flaps. These advantages are discussed.
