Abstract
To evaluate outcomes after percutaneous application of transilial pinning in dogs with seventh lumbar vertebral body fracture with concurrent lumbosacral luxation. We reviewed the medical records of dogs with seventh lumbar vertebral body fracture stabilized with percutaneous transilial pinning that were treated at our hospital between January 2000 and March 2014. Radiographic measurements were used for comparing craniocaudal and ventrodorsal displacement pre- and postoperatively. Seventeen dogs met the inclusion criteria. The neurological status of the majority of treated dogs improved quickly, with immediate pain reduction after surgery. Implants were well tolerated throughout the application period and were removed at a mean time of 54.4 ± 9.2 days. One dog experienced a major complication (implant failure) and required surgical revision a week after the initial procedure. Minor complications included pin-tract inflammation, signs of back pain lasting five weeks and acute lameness after implant removal. Postoperative radiographic measurements showed shortening of the vertebral body and residual dorsoventral dislocation. Otherwise, functional recovery was good (5 of 17 dogs) to excellent (10 of 17 dogs) in the majority of the patients. The use of two percutaneous transilial pins can be considered as treatment for the management of seventh lumbar fracture-luxation in dogs. Our modified stabilization technique is relatively easy to perform; less invasive on the soft tissues; and uses implants that are versatile, modifiable, and easily removable.
