Rabbit Splay Leg Syndrome – NAVLE Study Guide
Overview and Clinical Importance
Splay leg syndrome is a developmental musculoskeletal condition in rabbits characterized by the inability to adduct one or more limbs, causing them to extend laterally from the body at abnormal angles. This condition represents an important multisystemic disorder affecting rabbits and is frequently encountered in exotic animal practice. Understanding splay leg is essential for NAVLE candidates as it involves genetics, musculoskeletal development, nutrition, and long-term patient management.
Definition and Pathophysiology
Definition
Splay leg (also called splayed leg) is a postural deformity in which a rabbit cannot adduct (draw toward the body) one or more limbs. The affected limb(s) extend laterally from the body, typically at angles ranging from 45 to 90 degrees, resembling a seal's flippers. In severe cases, limbs may even fold backwards.
Underlying Pathophysiology
The pathophysiology of splay leg involves imbalanced development of the neural, muscular, and skeletal systems of the limb. Key anatomical findings include:
