The durability of thin superficial circumflex iliac artery perforator flap in sole reconstruction: Clinical experience with 18 cases.

BACKGROUND

The superficial circumflex iliac artery perforator flap's overall success in the reconstruction of the lower limb has been acceptable, but the sole of the foot remains more challenging. The purpose of this article is to report our experience employing the SCIP flap and evaluate its durability in reconstructing different units of the foot's sole, heel, middle, and forefoot.

PATIENTS AND

METHODS

This retrospective study reviewed 18 patients with sole defect reconstructed with free SCIP flap from 2017 to 2019. 18 free SCIP flaps were harvested depending on the superficial branch of SCIA (n = 16) or deep branch (n = 2). All flaps were thin and elevated above the scrapa's fascia. The heel (n = 10), middle foot sole (n = 5), forefoot sole (n = 2), and combined heel and midfoot in one patient were among the defect locations. Sole defects were caused by trauma in 10 patients (55.5%), while the rest of the causes were melanoma (three patients, 16.7%), diabetic ulcer (three patients, 16.7%), and unstable scar (one patient), and calcaneal osteomyelitis (one patient). The defect size ranged from 24 to 230 cm2 .

RESULTS

The flap dimensions ranged from 6 × 4 to 18 × 11 cm. Mean follow-up observations were 42.5 months. 72.2% of our patients developed protective sensation between 12-18 months. No ulcerations were observed, and all of the patients had successful functional recoveries with satisfying cosmetic outcomes.

CONCLUSION

The SCIP flap can be an optimal durable skin flap for weight-bearing sole reconstruction. SCIP flap has the advantage of being thin minimizing the problem of shearing, the need for secondary procedures, and the faster recovery of protective sensation that could prevent ulceration.
