Lower leg

Postoperative problems affecting the lower leg can be remedied as follows

A visible scar. The lower leg does not take a skin graft as well as the arm so scars are more obvious and prominent. Again, scar wound modification with silicone gels, sheets, pressure and massage can help. Formal scar revision or re-grafting may be necessary in the event of complete skin graft loss.
Lifting up of the great toe can be limited when a fibula flap has been used. Physiotherapy helps to a greater or lesser extent, depending on the degree of neuromuscular impairment.
Limping to a greater or lesser degree can occur and is greatly helped by wearing a solid shoe early on in the recovery and rehabilitation phase.
Altered or absent sensation in the area of surgery may be noticeable although this often is not very troublesome, counter-irritation treatments as described for the upper arm are useful.
Complete absence of sensation or sometimes unpleasant altered sensation on the outer surface of the lowest part of the leg and the side of the foot, if a sural nerve graft has been taken to replace missing or damaged nerve elsewhere. Learning to live with the loss of sensation is really the most important solution to this.
Very rarely loss of the foot has been reported when a fibula flap has been used and the remaining blood vessels to the lower leg and foot (the anterior (front) and posterior (back) tibial arteries) have been diseased or absent. Amputation rehabilitation with a prosthesis is the treatment but no-one wants to experience this postoperative problem.
