Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
