The Microsurgical Calcaneus Osteocutaneous Fillet Flap After Traumatic Amputation in Lower Extremities: Flap Design and Harvest Technique
2019
BACKGROUND: Attempts to salvage upper and lower extremities have performed more frequently in recent decades, although there are clear cases that cannot be salvaged. The purpose of this retrospective study was to present our experience in using free calcaneus osteocutaneous fillet flap for preserving below-knee amputation stump after traumatic amputations or functional preserving after nonsalvageable lower extremities. METHODS: Between January 2012 and May 2017, 11 free calcaneus osteocutaneous fillet flap were used to preserving or lengthening below-knee amputation stump secondary to amputation on 8 males and 3 females. Patients' information and postoperative data were collected, including age of patient, sex, amputation site, flap survival, sensation recovery, and number of complications. RESULT: All amputations were trauma related and secondary to motor vehicle accidents (n = 8) and industrial accidents (n = 3). The age of the patients ranged from 16 to 59 years, with a mean of 34.4 years. Free calcaneus osteocutaneous fillet flap were designed and harvested from all patients. All flaps survived and 2 complications developed in 2 patients. Nine of 11 patients obtained protective sensory recovery during the period of follow-up. CONCLUSIONS: The free calcaneus osteocutaneous fillet flap harvested from the amputated limb provides reliable and robust tissue for reconstruction of large defects of the residual limb without additional donor-site morbidity.
