OBJECTIVE: To explore the anatomical basis of blood supply and heel reconstruction by reversed island fibular musculocutaneous flap. METHODS: The blood supply of fibular musculocutaneous flap and the biomechanical characteristics of heel were studied by anatomical examination. One case with right heel full defect because of explosion injury was repaired by transfer of reversed island fibular vessels. The fibular flap was 14 cm in length with part of peroneus muscle and long flexor muscle of great toe. RESULTS: The lower part of fibular artery had plentiful anastomosis with anterior tibial artery and posterior tibial artery, which could provide ideal reversed blood supply. The rotatory point of vessel pedicle could be chosen according to the need of operation. The lowest site might be above 6 cm to lateral malleolus, and the vessel pedicle was 20 cm in length. The morphological feature of the reversed island fibular musculocutaneous flap was suitable to the biomechanical character of heel. The patient achieved satisfactory clinical result, the musculocutaneous flap survived well for 10 months of follow-up. CONCLUSION: The reversed island fibular musculocutaneous flap provide a new method for repairing the severe heel defect, especially in full defect of calcaneus and cuboid bone.
OBJECTIVE To investigate the repairing method of soft tissue defect of heel, pedicled island myocutaneous flap of flexor digitorum brevis was designed. METHODS From 1984 to 1997, 26 cases with soft tissue defect of heel were adopted in the clinical trial. Among them, the were 18 males, 8 females and the age ranged from 15 to 60 years old. The area of wound ranged from 2.5 cm x 1.5 cm to 8.0 cm x 6.0 cm. RESULTS After operation, all of the flaps survived. They were followed up for 9 to 72 months. All of the flaps had primary healing except in one there was infection of peripheral of the flap. The contour of heel was satisfactory the sensation of flap was good and the weight-bearing function was also successful. CONCLUSION It was concluded that the myocutaneous flap of flexor digitorum brevis could be used to repair the soft tissue defect of heel because of its nearby position, hidden location, good recovery of skin sensation and weight-bearing function, Besides, the procedure of this operation was simple and the anti-inflammatory potential of the flap was high. However, Because of the limited donor area, the pre-operative design was important.

Methods From September 1998 to March 2009, skin defects of the heelstick of 42 patients were repaired with the perforator artery flap of medial plantar. Adequate preparations were given on the wound before operation. Based on the results of color Doppler ultrasound of the medial plantar vascellum before or during the operation, the flap was designed according to the size of the defect and transferred to repair the defect. Results All the flaps survived completely except two flaps were partial lynecrotic in the distal, which healed after change of dressing. Conclusion Perforating artery flap of medial plantar is an ideal way to repair skin defect of the heelstick.
OBJECTIVE The repair of soft tissue defect of heel by traditional operation did not restore the sensation of the heel. METHODS In order to solve this problem, the saphenous neurovascular skin flap reinnervated by end-to-side neuro-anastomosis was designed and 3 male patients with soft tissue defects of the heel were so treated. Grossgraft of saphenous neurovascular skin flap was employed for repairing the soft tissue defects of heel and the pedicle was divided at 21 days after operation. The end-to-side neuro-anastomosis was used to reinnervate not only the skim flap, but also the skin area of the medial malleolus, medial aspect of the foot and the big toe of the donor limb. RESULTS After follow-up of 6-12 months, the walking and weight bearing functions of the affected limbs were good, the contour of the grafted area was satisfactory, and the recovery of sensation of the skin flap, the medial malleolus, the medial aspect of the foot and the big toe was observed. CONCLUSION 1. Crossgraft of the saphenous skin flap was an effective method to repair the soft tissue defect of the heel; 2. End-to-side neuro-anastomosis could restore the sensation of the skin flap.
Objective To compare the cl inical effectiveness of the medial plantar flap, the retrograde posterior tibial vascular flap, and the reverse sural neurocutaneous flap in repairing defect caused by resection of cutaneous mal ignant melanoma (CMM) in the heel region. Methods The cl inical data were retrospectively analysed from 24 patients with defect who had CMM in the heel region and were treated by radical excision and flap repairing between March 2007 and March 2010. Defects were repaired with the reverse sural neurocutaneous flaps of 8 cm × 7 cm-14 cm × 12 cm at size in 12 patients (groupA), with the medial plantar flaps of 6 cm × 5 cm-8 cm × 7 cm at size in 7 patients (group B), and with the retrograde posterior tibial vascular flaps of 9 cm × 7 cm-15 cm × 13 cm at size in 5 patients (group C). There was no significant difference in gender, age, duration of illness, cl inical stage, and size of CMM among 3 groups (Pgt; 0.05). The donor site was sutured directly or by free skin graft. Results No significant difference was found in the operation time and the intraoperative blood loss among 3 groups (P gt; 0.05). All skin flaps or grafts survived and wounds healed by first intention. The patients were followed up 1-3 years. The flaps had normal texture and color with no ulcer in 3 groups. At 1 year after operation, the sensory recovery rates of the flaps were 0, 100%, and 20% in groups A, B, and C, respectively, showing significant difference among 3 groups (P=0.001). The patients had normal appearance of heel and pain-free walking [10 (83%) in group A, 6 (86%) in group B, and 4 (80%) in group C] of heel region, showing no significant difference among 3 groups (χ2=40.000, P=0.135). Heel pain existed in weightbearing walking of 3 groups, and there were significant differences in visule analogue scale (VAS) score (Plt; 0.05). There was no significant difference in range of motion of ankle joint among 3 groups (P gt; 0.05). Except 1 patiant of relapse in group A at 1 month after operation, no relapse was observed in the other patients during follow-up. Conclusion The medial plantar flap, the retrograde posterior tibial vascular flap, and the reverse sural neurocutaneous flap can achieve the good cl inical effectiveness in treating heel defect caused by the resection of CMM. And the medial plantar flap is the first choice in small skin defect of heel area.
OBJECTIVE: Soft tissue defect of heel is not uncommon. Transplantation of free cutaneous flap and transfer of axial cutaneous flap have been used in treating such defect successfully, but both of them are somewhat complicated. Local plantar rotatory flap might show great importance in this field. METHODS: Since March 1993 to March 1998, 9 cases with soft tissue defect of heel were repaired by local plantar rotation flaps. The size of defect ranged from 2 cm x 4 cm to 6 cm x 8 cm, and it was designed superficial to plantar fascia. The flap was medially based, and nutrilized by proximal plantar subcutaneous plexus of blood supply as well as lateral and medial plantar nerve. RESULTS: Followed up 4 months to 2 years, all the flaps were survived. Sensation of the flap was preserved in 7 patients, who had normal sensation of the donated area preoperatively. The transferred flap was endurable to body bearing. CONCLUSIONS: The flap is easily prepared with reliable blood supply and sensation of the flap preserved. The method is worthy to be recommended for widely use because of its advantages over other methods.
Three cases of the defects of theskin and soft tissuess of the heel orsole complicated with defect of thecalcaneus bone from trauma weretreated. Primary replantation andreconstruction surgery was applied.The author believed that the recon-struction of the defect of the heelshould include the repair of the heelstructures and the sensation of the sole.
