Partial replantation after traumatic proximal lower limb amputation: a one-stage reconstruction with free osteocutaneous transfer from the amputated limb.

A case of immediate stump reconstruction following proximal leg amputation below the knee is reported. Additional length and sensation are conferred to the stump by free autotransplantation of a composite flap taken from the unsalvageable amputated leg. This flap provided 13 cm of vascularized tibia invested in the skin of the foot. This operative procedure facilitated the fitting of a prosthesis and preserved knee function despite an initial very proximal amputation.
