THE distinction between flaps with an axial pattern and those with a random pattern has been made (McGregor, 1972) and the implications of this distinction in terms of flap design has been discussed by Smith (1973).It has been shown (McGregor and Jackson, 1970, 1972) that the presence of an axial vascular pattern in a flap frees it from many of the restrictions normally associated with flaps, allowing it to be raised without prior delay despite a single pedicle and length considerably in excess of breadth.The two flap types might be defined in such terms as:Axial Pattern Flap-a single pedicled flap which has an anatomically recognised arterio-venous system running along its long axis.Such a flap, because of the presence of its axial arterio-venous system, is not subject to many of the restrictions which apply to flaps in general.Random Pattern Flap-a flap which lacks any significant bias in its vascular pattern.Such a flap, because it lacks an axial arterio-venous system, is subject to the restrictions hitherto generally accepted in flap practice.
