Reconstruction of Plantar Forefoot Area with Lateral Toe Pulp Flap: Case Report and Literature Review.

ABSTRACT

Reconstruction of the plantar forefoot area is challenging because it performs important functions, including carrying the body weight and balancing the ambulation gait, and lacks similar skin and soft tissues to manage the adjacent region. Herein, we shared our experience of using a lateral toe pulp flap and reviewed the relevant literature on this topic. A 33-year-old man presented with a large granuloma in the left plantar forefoot area after undergoing multiple operations owing to the diagnosis of callus. After tumor excision, the wound exhibited tendon exposure and a large infected dead space in the myofascial layer. After serial debridement with negative pressure wound therapy, the wound, which measured ~3.5 × 2.5 cm2, was reconstructed using a lateral toe pulp flap. The flap was transposed to obliterate the dead space; the remaining skin defect (size ~2 × 2 cm2) was resurfaced with a full-thickness skin graft, harvested from the left inguinal region, followed by primary closure of the flap donor site. The flap completely survived. The lateral toe pulp flap is an easy, effective, and reliable option for reconstruction of the defects in the plantar forefoot area.
