Brief Summary:
The aim of the study is to evaluate the outcomes of coverage of soft tissue defects of leg and foot by modified sural flap versus anterolateral thigh flap
Detailed Description:
The leg and foot contain a thin subcutaneous layer and few muscles, thus the tibia and tendons can easily become exposed due to trauma. Therefore leg and foot injuries are often associated with a loss of soft tissues and exposed fractures.
one of the following reconstructive options are chosen:
1. The defect is allowed to heal by secondary intention.
2. The wound is closed primarily.
3. A split or full thickness skin graft and or neodermis is applied.
4. A local random flap or propeller flap is transposed or advanced.
5. A pedicled or island flap is transferred.
6. A microvascular free flap is transferred. The method of soft tissue reconstruction chosen hinges on the patient's medical condition, the surgeon's experience, the size of the wound, the vascular status of the foot and the exposed structures the skin in this region has low flexibility and the subcutaneous circulation does not allow the use of long randomized flaps, the task of finding flaps to cover bones or tendons in wounds with cutaneous loss in the legs and feet is difficult.
The sural flap acts as an axial flap and has 3 sources of nutrition,the vascular plexus of the deep fascia, the medial superficial sural artery which follows the medial sural nerve and the arteries that follow the minor saphenous vein. Venous return is ensured by the minor saphenous vein which may be used as a distal pedicle to provide reverse flow.
sural flap has the advantages of easy and quick harvesting without sacrificing major arteries and can be done in one stage operation.
In the other hand,Since introduction of the anterolateral thigh flap in 1984 by Song et al it has gained widespread popularity, especially in Asian countries, where it has replaced the radial forearm flap as being the workhorse in head and neck surgery.
Anterolateral thigh flaps have been introduced also in lower extremity reconstruction.
