Extensor hallucis longus tendon and soft‐tissue reconstruction with palmaris longus tendon included in a radial forearm free flap: A case report. Issue 3 (12th October 2019) - Lucattelli, Elena
Abstract: Reconstruction of foot structures is challenging because of the need to restore both anatomy and function. Extensor hallucis longus (EHL) excision without reconstruction could result in a flexion deformity of the toe at the interphalangeal joint. In this report, we present a case of the use of a palmaris longus tendon included in a fasciocutaneous radial forearm free flap to reconstruct EHL tendon and soft tissues of the distal foot dorsum. A 41‐year‐old woman presented with a recurrence of myxoinflammatory fibroblastic sarcoma on the medial part of the left foot dorsum. The EHL tendon was sacrificed, leaving a soft‐tissue defect of 14 × 5 cm and 14‐cm tendon gap. A 14 × 5 cm radial forearm flap with a 16‐cm section of palmaris longus tendon was harvested from the left forearm. Radial artery and its comitant vein were anastomosed with dorsalis pedis artery and vein. EHL tendon repair was performed from the composite mass to the proximal and distal stumps. No complication in the postoperative period occurred. At latest follow‐up, 12 months postoperatively, the patient showed a normal joint function and was satisfied with the treatment. Palmaris longus tendon included in a radial forearm free flap could be recommended for combined soft tissue and tendon defects, particularly on the foot dorsum.
