BackgroundPseudarthrosis can develop as a complication after conservative or operative fracture treatment and after elective orthopedic surgery. The treatment is challenging and is made more difficult when accompanied by large soft tissue defects or impairments in wound healing. In this case close and early coordination between trauma and plastic surgeons is crucial in order to develop a coherent and interdisciplinary treatment plan.MethodsDue to the positive effects on bone consolidation and osteomyelitis, timely soft tissue reconstruction via a pedicled vascularized flap or free flap coverage should be preferred. If blood circulation in the affected extremity appears to be compromised, this should first be optimized by vascular intervention or bypass surgery. In atrophic, aseptic pseudarthrosis, bone and soft tissue reconstruction can be performed consecutively in one single procedure, whereas septic pseudarthrosis always require complete resection of all infected debris prior to wound closure. Examples of two commonly used free flaps are the latissimus dorsi muscle flap and the fasciocutaneous anterolateral thigh (ALT) flap. As multiple variations have been described for both procedures, the reconstructive portfolio lists many additional options available for soft tissue reconstruction. Fasciocutaneous flaps should be preferred whenever bone consolidation requires additional surgical interventions in the future.
