A transfemoral amputation was performed preserving the existing compressive osseointegration device, and limb lengthening was achieved using intercalary and distal femoral segments. 3.5 years after amputation and lengthening, the implant remains well integrated and the patient is ambulatory.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
