Objective To investigate the clinical results of allograft and sural neurovascular flap in repairing calcaneus and skin defects.Methods From February 1996 to December 2002, allograft and sural neurovascular flap were used to repair calcaneusand skin defects in 6 cases. The causes included road accident in 3 cases, strangulation in 2 cases and crashing object in 1 case. The defect locations were at theback of the calcaneus( 1/3, 1/2 and 2/3 of calcaneus in 3 cases, 2 cases and 1case respectively). The flap area ranged from 6 cm×7 cm to 12 cm×17 cm. Results The flaps survived completely in 4 cases; the distal flaps necrosed partly in 2 cases and the wound healed by dressing. The postoperative X-ray films showed that the repaired bone and joint had normal position and the arcus plantaris recovered. After a follow upof 6 months to 3 years all the patients were achieved bone union in allograft and had no complications of absorption, infection and repulsion. The weightbearing and walking functions were restored and the injured foot obtained a satisfactory contour. After 36 months of operation, the sensory recovery of foot occurred. Conclusion The used-allograft iseasy to be obtained and arcus plantaris is easy to recover. The reversesural neurovascular- flap in repairing calcaneus and skin defects has the following advantages: the maintenance of blood supply for injured foot, the less dangerous operation, the simple procedure, the recovery of walking function, and the good appearance and sensation.
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.
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.
Objective To discuss the surgery procedure and the cl inical effectiveness of repairing skin and soft tissue defects in the lateral foot and the heel with the abductor digiti minimi muscle flap. Methods Between July 2002 and October 2010, 8 patients with skin and soft tissue defects in the lateral foot and the heel were treated. There were 6 males and2 females with an average age of 42 years (range, 28-65 years). The locations were the left foot in 5 cases and the right foot in 3 cases. Defects were caused by ulcer of the heel in 2 cases, by poor heal ing of incision after calcaneus fracture surgery in 1 case, and by crushing in 5 cases. The defect size ranged from 1.5 cm × 1.0 cm to 8.0 cm × 2.6 cm. The disease duration was 30 minutes to 26 months. The result of bacterial culture was positive in 2 cases. After 9 to 15 days of debridement and dressing change, defects were repaired with the abductor digiti minimi muscle flap of 5.6 cm × 1.5 cm to 7.6 cm × 1.8 cm at size. The donor sites were sutured directly. Results Partial necrosis of muscle flap occurred in 1 case at 4 days after operation, which was cured by symptomatic treatment, and the other muscle flaps survived. All incisions of the donor sites healed by first intention. The muscle flaps survived and the granulation grew well at 9-21 days after operation, and the muscle flap wounds were repaired by free leg edge thickness skin grafting. Wounds were repaired by one-stage free skin grafting in 1 case and by two-stage free skin grafting in 7 cases; all skin flaps survived and wounds healed by first intention. Seven patients were followed up 9-18 months (mean, 11 months). The appearance, texture, and sensation were satisfactory. The two-point discrimination was 16-23 mm (mean, 19.5 mm). Epidermal abrasion occurred in 1 case of heel ulcer after weigt-bearing walking. Hallux valgus and muscle weakness occurred in 1 case of necrosis of the peroneus length tendons; and the satisfactory results were achieved in the other patients. Conclusion It has satisfactory effectiveness to use the abductor digiti minimi muscle flap for repairing skin and soft tissue defects in the lateral foot and the heel, which has the advantages of easy-to-operate, safe, less injury at donor site, goodappearance and texture, and good recovery of sensation.
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.
Objective To study the surgical resection and reconstruction methods of mal ignant melanoma on the heel. Methods Between July 2007 and June 2009, 15 cases of mal ignant melanoma on the heel were treated. There were 9 males and 6 females, aged from 32 to 71 years with a mean age of 47.2 years. Of them, 13 patients were initially treated, and 2 patients received repair after local excision. Tumor thickness was from 0.6 mm to 7.2 mm, and the size of the lesion was from 1.3 cm × 0.5 cm to 5.0 cm × 3.5 cm. According to the American Joint Committee on Cancer (AJCC) stage system, there were 1 case of IA, 2 cases of IB, 3 cases of IIA, 5 cases of IIB, 1 case of IIC, and 3 cases of III. Wide excision was performed in all cases. Defects were repaired by medial pedal skin flap (5 cases), lateral pedal skin flap (2 cases), and retrograde skin flap suppl ied by sural nutrition blood vessels (8 cases), and the flap size ranged from 7 cm × 5 cm to 12 cm × 8 cm. Inguinal lymph node dissection was performed in 3 patients. Wounds of donor site were repaired by skin graft. Results One case had marginal necrosis of lateral pedal skin flap and 2 cases had local necrosis of medial pedal skin flap on the skin graft; the other flaps and skin grafts survived and incisions healed by first intention. All patients were followed up from 12 to 36 months (mean, 21 months). Considering the recovery of the function and sense, the best result was acquired in the lateral pedal skin flap, followed by the medial pedal skin flap, and the poor result in the retrograde skin flap suppl ied by sural nutrition blood vessel. No patient had local recurrence at follow-up. Five patients had inguinal lymph node metastasis, and 1 patient died of lung metastasis. Conclusion Wide resection can provide satisfactory local control for mal ignant melanoma on the heel. Local flap can cover the wound safely, but the retrograde skin flap suppl ied by sural nutrition blood vessel has poor sensory recovery.
OBJECTIVE: To investigate the efficacy of different flaps in the treatment of skin defect of hell. METHODS: Forty-six patients with skin defect of hell were adopted in this study. There were 39 males and 7 females, 29 years old in average. Six different flaps were applied in the reconstructive operation, 14 plantaris medialis flaps, 4 flexor digitorum brevis muscle flaps, 3 abductor hallucis flaps, 7 latissimus dorsi flaps, 16 distal medialis flaps of leg pedicled with the cutaneous branch of posterior fibial artery, 2 foot dorsum flaps. RESULTS: All the flaps survived, primary healing of the wound in 45 cases and secondary healing in 1 case. Followed up for 3 months to 4 years, 43 patients obtained good flap sensation, the function of weight bearing were satisfied in 43 patients. CONCLUSION: The six different flaps should be applied according to patient’s condition individually. The sensation of flap is very important to the function of weight bearing.
To introduce the experience and comprehend of appl ication of many kinds of skin flaps in repair of heel skin and soft tissue defect. Methods From August 1993 to April 2007, 242 cases of skin and soft tissue defect on heel were treated. There were 157 males and 85 females aged 27-76 years. There were 35 cases of unstable scar, 46 cases ofchronic ulcer, 57 cases of squamous cell carcinoma, 72 cases of mal ignant melanoma and 32 cases of injury. The defect area ranged from 2 cm × 2 cm to 8 cm × 14 cm, wound was with low-grade infection in 51 cases. The course of disease was 1 hour to 5 years. The lateral calcaneal flaps (34 cases), the dorsum pedis flaps (15 cases), the medial plantar artery island flaps (108 cases), the sural neurovascular flaps (36 cases), the saphenous neurocutaneous vascular flaps (26 cases) and free (myocutaneous) skin flaps (23 cases) were used to repair heel wounded surface according to specific location of heel wounded surface, range of skin and soft tissue defect. The size of the (myocutaneous) skin flap was 3.0 cm × 2.5 cm to 15.0 cm × 9.0 cm. The donor area was directly sutured or covered with skin grafts. Results In 242 cases, 235 cases achieved heal ing by first intention, 5 cases had partial necrosis of flaps, 2 cases had mild infection. The donor area healed by first intention. A total of 217 patients were followed up for 1 month to 60 months. The color of flaps were normal and the texture of flaps were softer than that of normal heel tissue; the flaps were wearable, the shape of flaps were satisfactory. The patients can walk after 6 months of operation, andthe gait was normal. In 118 cancer patients, no local tumor recurrence occurred, and distant metastatic lesions were observe in 22 mal ignant melanoma patients. In 32 cases of mal ignant melanoma followed up 60 months, no distant metastatic lesions were found. Conclusion In base of following the primary disease treatment, heel function reconstruction and contour structural feature remodel ing, we adopted some kind of island or free (myocutaneous) skin flap can be used to repair heel wound. The ideal effect in heel function reconstruction and contour structural feature remodel ing were obtained.
