ABSTRACT

A savannah monitor, Varanus exanthematicus, presented with a history of anorexia and constipation. After not responding to medical therapy, an exploratory coeliotomy revealed normal viscera with compression of the pelvic canal. There was instability of the pelvis on digital cloacal exam, with bilateral sacroiliac luxation diagnosed on radiographs. The luxations were repaired via arthrodesis and stabilization using two type I external skeletal fixators. Necropsy was performed three months after surgery. The left sacroiliac luxation healed without complications. The right sacroiliac luxation, which was still unstable after surgery, had evidence of bacterial and fungal osteomyelitis.
