BackgroundThe reverse sural artery flap (RSAF) is widely used to reconstruct foot and ankle defects. Although it is commonly used in a nonsensate type, there has been controversy as to whether it provides sufficient stability and durability when applied to weight-bearing heels. The aim of this study was to evaluate patient outcomes after weight-bearing heel coverage using a nonsensate RSAF.MethodsTwenty-three patients who underwent reconstruction surgery of the weight-bearing heel with RSAF from 2004 to 2018 in a tertiary hospital were retrospectively reviewed. All surgeries were performed without a sensate procedure. The patients' experience of pressure sore on the flap area and the ability to use normal footwear were investigated. Light touch, Semmes-Weinstein test (SWT), and two-point discrimination tests were assessed, along with postoperative wound complications.ResultsHeel damage etiologies included malignant tumors in 14 (61%), trauma-related in 7 (30%) and diabetic ulcers in 2 (9%) patients. Patient mean age was 58 years (range, 18-93 years) and the mean follow-up period was 57 months (range, 12-185 months). The mean size of the flap was 64.1 cm2 (range, 20-169 cm2). All flaps healed without major complications. All returned to daily living activities and 20 (86%) patients were able to use normal footwear. Of the 11 patients who had available measurement records, 8 (73%) showed a light touch sense. The mean SWT value was 4.31 (range, 3.61- 4.56). Two-point discrimination was not observed in any of the patients. Two patients had experienced superficial ulcers on the flap within a one-year postoperative period, which spontaneously healed and did not recur. No full-thickness ulcers were observed during the follow-up period.ConclusionsThe results of this study suggest that patients who underwent nonsensate RSAF for the reconstruction of the heel could expect to maintain the property for stable weight-bearing without pressure sore.Copyright © 2021.
