Abstract:

This year we finalized testing of the external fixator and instrumented it with a strain gauge. We also initiated sheep surgeries. Three sheep have been operated so far. Two were unsuccessful but the third sheep is doing well in the immediate post-operative period. The surgeries themselves have been unproblematic, but the first sheep had to be euthanized because of hardware failure 4 days post-operatively. The reason for this is unknown, but there appears to have been a discrete, high-impact event. In response to this, we have installed CCTV cameras for constant surveillance and re-designed the sling for post-operative support. The second sheep died during the anesthesia recovery process. Despite thorough necropsy, the cause of death remains unknown.
