Division of tibia and fibula with electric saw. Care is taken to smooth medially and posteromedially on the bone end. The bone is rounded rather than simply beveled. Beveling and meticulous rounding of distal tibia. The use of a reciprocating power saw makes the transection of the fibula considerably easier and less traumatic to surrounding tissue.
Some surgeons prefer sectioning the fibula first.
The stability provided by the intact tibia makes fibula division easy. When power equipment is used, fibular instability has not presented a problem. The fibula is left somewhat longer than in previously described amputation techniques because the modern total-contact socket depends upon the more cylindrical, broad stump for rotary stability. Except in children and adolescents, no attempt is made to gain tibiofibular bone bridging. Fibular instability has not proven to be a significant problem in prosthetic fit.
