Case studies

We are very proud to post the first case of lumbosacral stabilization using our spinal fixation and distraction system which is designed and manufactured in Italy exclusively for the veterinary world.
The operation was performed by Dott. Massimo Baroni at the ultra-modern Valdinievole Veterinary Clinic in Monsummano Terme.

German shepherd, male, 10.5 y.o.

  • Clinical signs: Lumbosacral pain, moderate urinary incontinence.
  • Diagnosis: degenerative lumbosacral stenosis (DLSS) with joint instability.
  • MRI diagnosis: Lumbosacral compressive disc protrusion, sacral retrolisthesis, bilateral foraminal stenosis
  • Surgery: Dorsal lumbosacral laminectomy, removal of protruded disc material, distraction and insertion of titanium interbody cage, facet joint fixation with 2.7 mm screws, distraction joint fixation with polyaxial pedicle screws.
  • Post. op X-ray: good L7-S1 vertebral alignment and distraction with excellent opening of the lateral foramina.


New case of lumbosacral stabilization using our spinal fixation and distraction system which is designed and manufactured in Italy exclusively for the veterinary world.
The operation was performed by Dott. Massimo Baroni
  Rhodesian Ridgeback, male, 6 year old.

  • Clinical signs: chronic lumbosacral pain.
  • Xrays Diagnosis: mild sacral retro-listhesis with ventral displacement of the dorsal sacral lamina.
  • MRI diagnosis: lumbosacral disc protrusion and ventral displacement of the sacral lamina causing focal spinal canal stenosis.
  • Surgery: lumbosacral dorsal laminectomy, removal of the disc protrusion , dorsal disc fenestration, fixation with transarticular 2,7 mm titanium screws and polyaxial pedicles screws.
  • Post. op X-ray: good L7-S1 vertebral alignment and distraction with excellent opening of the lateral foramina.

 

 

 

 
 


  

 

  

  

 

Clinica veterinaria OL

Relapsing low back pain without response to medical therapies.

Labrador retriever, male, 8 years old 
 

Dr. Raffaele Gilardini 

Medical Director of Clinica Veterinaria Città di Voghera.

 

  • Clinical Signs: Relapsing low back pain without response to medical therapies
  • Radiographic diagnosis: mild spondylolisthesis and spondylosis L7-S1 with increased radiopacity of formina.
  • MRI Diagnosis: severe L7/S1 disc protrusion with compression of the cauda equina nerve roots, bilateral foraminal stenosis and ventral spondylosis. The resonance in traction highlights a lesion of a dynamic type (lumbo-sacral instability).
  • Surgery: L7-S1 laminectomy, dorsal fenestration of the disc and removal of the disc protrusion, distraction and insertion of a cage into the disc space, L7/S1 stabilization with 2.4 mm titanium transarticular screws and 3.5 mm polyaxial pedicle screws.
  • Postoperative radiography: good L7-S1 alignment and vertebral distraction, cage positioned correctly, with opening of the foramina.
  • Postoperative process: The patient gets up 3 hours after surgery and is discharged after 24 hours.
