Reconstruction of Ankle and Foot Defects

Not Applicable

• Conditions: Foot Injury
• Interventions: Procedure: medial plantar artery flap; Procedure: Distally based sural artery flap

• Registration Number: NCT04967040
• Lead Sponsor: Sohag University

Brief Summary

Reconstruction of soft tissue defects around the foot and ankle region is a challenging problem for reconstructive surgeons due to the lack of locally available tissues for transposition, the relatively poor skin circulation, and the special structural characteristics of this area, bones and tendons can easily become exposed due to trauma. so foot injuries are often associated with a loss of soft tissues and exposed bones . The plantar skin is thick, with solid anchorage to the deep structures. Therefore, the reconstructive aim is to restore the stability of the foot skin to adapt to weightbearing and to resist shearing forces. In addition, good sensibility should be considered in the reconstruction. Additional considerations the ankle region has great tension during movement, and good stability is required for shoes wearing. The medial plantar flap has been effectively used in the reconstruction of soft tissue defects localized to the plantar foot, forefoot, posterior heel, and ankle in small to medium sized defects . This flap can be transferred to the defect as a proximally or distally pedicled island flap . The distally based sural artery flap frequently used for reconstruction of soft tissue defects of the lower leg, foot and ankle in medium and large sized defects .Fascio-cutaneous flaps are highly effective and easy to perform.

This study is a comparative study designed for assessment of the clinical applications of distally based sural flap versus medial plantar artery flap regarding the size of the defect , operative technique and their outcomes (success and complications) as a reconstructive option for foot and ankle defects.

group 1 : medial plantar artery flap	medial plantar artery flap	-
group 2 : distally based sural artery flap	Distally based sural artery flap	-

Primary Outcome Measures

Name	Time	Method
Difference in functional outcome between group 1 and group 2	Difference in functional outcome between group 1 and group 2 is measured at 4 months postoperative	The functional outcomes are graded as excellent, good, and poor. The criteria for excellent results are the survival of the flap without any flap loss and walking without any aids . Survival of the flap with minimum complications and walking with aids are the criteria for good results. A result is considered poor when an alternative reconstructive procedure is considered
