Osteosynthesis of a mid-diaphysis femoral fracture by using a type I tie-in fixator in a kookaburra (Dacelo novaeguineae)

Abstract

In this case report, the successful management of a traumatic fracture of the femur in a kookaburra using a type I tie-in-fixator (TIF) is described. A domesticated, five-month-old kookaburra (Dacelo novaeguineae) suffered trauma due to interspecies aggression. Clinical and radiographic examination showed a closed, multiple transverse, spiral femoral fracture, located in the mid-diaphysis. Reduction of the fracture was managed using a type I TIF, combining an intra-medullar (IM) pin in combination with an external skeletal fixator. Postoperative radiographs confirmed an optimal reduction of the fracture and a correct placement of the type I TIF. Recovery was uneventful and correct positioning and normal functioning of the leg were observed immediately following surgery. One week postoperatively, the bird removed the external fixation but this did not interfere with the acquired stability and positioning of the affected leg. Two weeks after the surgery, radiographs confirmed a good healing of the fracture as callus development and bridging of the cortices were present. Based on the clinical and radiographic findings, it was decided to remove the IM pin. During a three-month follow-up period, the kookaburra showed full recovery.
