    Abstract:
    BACKGROUND: Soft-tissue defects of the foot and lower leg caused by traumatic injury, tumor ablation, or infection associated with osteomyelitis often require coverage by flaps. One excellent option for reconstruction of these defects is the distally based neurofasciocutaneous sural flap. It allows rapid and reliable coverage of defects from the distal third of the lower leg to the forefoot without significant functional donor-site morbidity. However, the maximal size of the flap is limited by the delicate perfusion of the arterial network associated with the superficial sensory nerve. Delay procedures may increase the reliability of large sural flaps. METHODS: The authors successfully used delayed sural flaps based on a two-step procedure for the treatment of 11 patients (three women and eight men, age 50.1 +/- 20.0 years) with osteomyelitis (n = 3), melanoma (n = 3), sarcoma (n = 1), squamous cell carcinoma (n = 1), posttraumatic defects (n = 2), and recurrent gouty ulcer (n = 1). The delay period ranged from 7 to 15 days (9.7 +/- 3.1), the length of the flap was from 9 to 19 (14.8 +/- 3.0) cm, and the width of the flap from 7 to 12 (9.2 +/- 1.3) cm. Temporary wound coverage was achieved by vacuum-assisted closure during the delay period. RESULTS: All defects were covered successfully without major complications. CONCLUSIONS: The delay procedure positively affects the viability of large sural neurofasciocutaneous flaps. The authors recommend this modification for patients with large defects at the distal third of the lower leg or foot, requiring a two-step surgical approach due to the underlying disease.
