In the treatment of fractures in birds external fixation plays an important role. In birds with a body mass <300 g splints are typically used, whereas in larger birds surgical external skeletal fixation (ESF) is favoured. Type 1 ESF and type 2 ESF are used to treat fractures of ulna and metacarpus and tibiotarsus and tarsometatarsus, respectively. The combination of intramedular pinning and type 1 ESF (IM PIN „Tie in“ ESF) is favoured for the treatment of humeral and femoral fractures. The models of connecting bars used in avian surgery include the Kirschner-Ehmer-System, polymethylacrylates as well as tubular fixators. The F.E.S.S.A. tubular fixator has additional advantages by being especially light weight, having a favourable price and allowing easy addition or removal of pins. The knowledge about the special musculoskeletal anatomy in birds is essential for successful osteosynthesis and includes aspects such as pneumatisation, calcium storage, and an increased tendency for the occurrence of comminuted fractures.
