title: Suitability of the scapular flap for reconstructions of the foot.
abstract: Eighteen patients with mainly a traumatic soft-tissue defect of the foot underwent reconstruction with a microvascular free scapular flap. Of the 17 successful transfers, 13 were to the weight-bearing parts of the foot. The stability and contour of the flaps were assessed after an average follow-up time of 3 years (range 1 to 5 years). The thicknesses of the scapular donor site and flap and the recipient site were measured by an ultrasound technique. The resistance of the flap to shear was measured with a dynamometer. The ultrasound measurements aided in refining our operative technique. In early cases, the flap thickness after transfer could be more than double what it was in the donor area. With proper tightening, the thickness could be reduced, with improvement in contour but no increase in soft-tissue stability or shear resistance of the flap. Without proper tightening, the scapular flap tended to be redundant when transferred to the foot. For good results, the patient should be lean, since the optimal thickness of the scapular donor site was less than 6 mm and the maximum thickness should not exceed 8 to 10 mm. The differences in shear resistance between the flaps were not associated with the soft-tissue stability of the reconstruction. The relative laxity of the flap on the plantar surface was found by several patients to be subjectively unpleasant. Although good contour could be achieved when covering the plantar heel, the tendency of the flap to develop abrasions and superficial breakdowns made it unsatisfactory for covering this area.(ABSTRACT TRUNCATED AT 250 WORDS)
