Résumé :

The lateral arm flap presents some drawbacks: the vascular pedicle is short (2-6 cm), and the flap is rather thick. An anastomotic network between the posterior radial collateral artery and the recurrent radial artery, demonstrated by our previous anatomical dissections, enables one to locate the skin paddle solely over the epicondylar region and the proximal forearm. Furthermore, since no skin is harvested over the lateral aspect of the arm, a random-type vascularisation for the distal skin can be excluded. This modification increases pedicle length up to 100% and limits the amount of subcutaneous fat. A series of 13 consecutive distally based lateral arm flaps was performed, and eight patients were followed up for a minimum of 12 months postoperatively. Flap size ranged from 8 x 5.5 cm to 23 x 7 cm (average, 14 x 6 cm), and pedicle length ranged from 9 to 14 cm (average, 10.5 cm). No venous grafts were needed. The mean flap harvesting time was 60 minutes. All the donor sites were closed primarily. One flap suffered from an arterial thrombosis and only partially survived, and another healed uneventfully after successful re-exploration of a venous thrombosis. Only one flap had to be partially debulked. The donor site scar was enlarged in one patient. Elbow mobility was unaffected by surgery. Patient self-assessment on the appearance of both the reconstruction and the donor site showed a high satiSfaction rate. The distally planned lateral arm flap presents decreased bulk and a longer pedicle when compared with the classical lateral arm flap with no added technical difficulties or morbidity.
