[Osteosynthesis with hinge joints and methylmethacrylate (author's transl)]. 1977

D Baumann, and A N Witt

Six cases have been described where an osteosynthesis was performed using the stem of a hinge knee joint in combination with methylmethacrylate and other osteosynthetic devices (screws, wires). Need for an osteosynthesis existed because of pseudarthrosis after supracondylar and high tibial osteotomies, intraoperative fracture for implantation of a total knee, reimplantation after deep infection, and fatigue fracture after a total knee. The advantage of the procedure lies in early mobilisation and weight bearing. We do not believe in reimplantation after an infected prosthesis. Instead, we recommend fusion after implant removal.
