A detailed understanding of lumbar spine anatomy and perioperative care requirements of rabbits is imperative for correct execution of the model both scientifically and ethically.

Medical records from a single research facility were retrospectively reviewed for adult NZW rabbits that underwent single level PLF (L4\u2010L5) between January 2016 and December 2019. The number of lumbar vertebrae per rabbit, fusion rates at 12\u2009weeks using iliac crest autograft and complications are reported.

Fusion rates at 12\u2009weeks for PLF using iliac crest autograft as assessed by manual palpation and radiographic assessment was 76.9% and 70.0%, respectively.
