[Reconstruction of a metadiaphyseal bone defect after open comminuted fracture of the proximal femur using a modified Masquelet technique]. / Rekonstruktion eines metadiaphysären Knochendefekts nach offener, mehrfragmentärer Fraktur des proximalen Femurs in modifizierter Masquelet-Technik.

ABSTRACT

The reconstruction of segmental bone defects after surgical treatment of infected delayed unions as well as nonunions, places the highest demands on the surgical technical implementation. After treating the fracture-related infection, guaranteeing biomechanical stability is crucial for the success of the treatment. The presented case describes the successful treatment of an infected delayed union after an open metadiaphyseal comminuted fracture of the proximal femur using a modified Masquelet technique. A solid allogeneic bone graft in combination with autologous cancellous bone were inserted into a 7 cm subtrochanteric defect zone and stabilized with a combined plate and nail osteosynthesis.
