Fixation of lumbar vertebral fracture-luxation using spinal stapling and tension band wiring in young companion animals

Abstract

Segmental spinal fixation for lumbar spinal injuries was performed in three young companion animals (rabbit, dog, and cat) presented with traumatic posterior limb paralysis. Neurological and radiographic examinations confirmed lumbar vertebral fracture–luxation at L1–L2 (cat), L2–L3 (dog), and L3–L4 (rabbit). Under general anaesthesia, fractures were reduced and stabilized using tension band wiring (dog and cat) and K-wire spinal stapling. K-wires were placed through the base of spinous processes and secured with orthopaedic wires to provide segmental stabilization. Nociception improved within 24 hr in the dog and rabbit. However, the dog and cat later died due to surgical site infection. The rabbit showed improved reflexes and general health but remained paraplegic.
