[Effectiveness of medial ankle branches propeller "Tennis racket-like" flap in repair of heel-ankle tissue defects].

OBJECTIVE

To investigate effectiveness of the medial ankle branches propeller "Tennis racket-like" flap in repair of heel-ankle tissue defect.

METHODS

Between June 2011 and June 2016, 50 patients with heel-ankle tissue defects were treated. There were 40 males and 10 females, with a median age of 35.6 years (range, 6-58 years). The defects were caused by trauma in 44 cases, scar deformity after trauma in 2 cases, chronic ulcer in 2 cases, and squamous cell carcinoma in 2 cases. The defects located at heel in 20 cases, ankle in 15 cases, and heel-ankle in 15 cases. The size of heel-ankle tissue defect ranged from 3.5 cm×2.0 cm to 13.0×10.0 cm. The course of disease ranged from 3 hours to 2 months (mean, 28 days). All wounds were repaired by the medial ankle branches propeller "Tennis racket-like" flap in a size of 3.8 cm×2.2 cm-13.4 cm×10.3 cm. The donor site was directly sutured in 5 cases or repaired by skin grafting in 45 cases.

RESULTS

All flaps survived and wounds healed by first intention. Partial necrosis of skin grafting occurred in 1 case, and the wound recovered by change dressing. The other skin grafting survived and wounds healed by first intention. Forty-eight patients were followed up 12 months after operation. The appearance, sensory, and function of repaired heel-ankle flaps were satisfactory.

CONCLUSION

For heel-ankle tissue defect repair, the medial ankle branches propeller "Tennis racket-like" flap has advantages of the high survival rate, reliable blood supply, and sensory recovery.
