The Comparative Orthopaedic Surgical Facility was founded by orthopaedic surgeon Dr. John Field. The facility provides animal models of human diseases (primarily in sheep) for the evaluation of new devices and technologies as a prelude to clinical assessment.

This dedicated facility undertakes diverse surgical research on these large animals and consists of an operating theatre, radiology, recovery and minor procedure facilities.

Additionally, this facility acquired a Magnetic Resonance Imaging (MRI) unit during 2007 to enhance its research capability and provide an animal soft tissue diagnosis service to veterinarians throughout South Australia, clinicians and researchers at Flinders Medical Centre (FMC) and the IMVS, Adelaide.

The surgery is coupled with animal holding pens on-site. The facility provides a world-class service to multiple commercial clients in the orthopaedic and pharmaceutical industries around the world. The Laboratory is well supported by the Flinders University Animal House.
