PurposeThe aim of the soft tissue reconstruction of plantar forefoot should yield weight-bearing function and aesthetic contour, which poses a significant challenge for reconstructive surgeons to provide an appropriate flap according to the "like for like" reconstructive principle. Local flaps and pedicled flaps have been described for the reconstruction of small- to medium-sized defects of plantar forefoot and achieved optimal results. However, reconstruction of extensive defects of plantar forefoot is rarely investigated. In this study, we present our experience using the free anterolateral thigh (ALT) flap in the reconstruction of extensive defects of plantar forefoot.MethodsBetween November 2011 and April 2017, 9 patients were treated for extensive soft tissue defects in the plantar forefoot areas with ALT flaps. The mean age at the time of surgery was 39.3 years (range, 25-64 years).ResultsThe follow-up period ranged from 12 to 77 months, with a mean of 31 months. All flaps survived well, and the patients were satisfied with the aesthetic and functional results. The size of the flaps ranged from 63 to 455 cm, with a mean of 197.7 cm. Seven patients with no bony involvement began to gradually weight-bear at 3 weeks postoperatively. During the follow-up time, postoperative ulceration at the reconstructed weight-bearing areas was not encountered.ConclusionThe ALT flap is a reliable option for treatment of extensive defects of plantar forefoot, resulting in an optimal functional and aesthetic outcome. Even when a total plantar loss exits, excellent results can be achieved.
