Jacky, a male Rottweiler age 11, suffered from tetraplegia that also restricted his mobility at the cervical spine and was associated with pain. MRI found a disc-protrusion with dynamic compression of the spinal cord at the C6-7 level. He was diagnosed with chronic progressive Caudal Cervical Spondylomyelopathy.
Jacky was treated with a 12mm x 5mm ACIF/ACDF cage, in ostaPek® carbon composite which is normally used in humans and designed for optimal space to carry living bone. Additional stabilization was also performed using Compact UniLock plates. The surgeon harvested cancellous bone graft from the dog’s humeral head, placing it inside the ostaPek® cage and anterior to the plate. Jacky recovered completely.
At 6 and 12 months, post-op x-ray images show progressive bony fusion growing through the ostaPek® carbon composite cage. Two years after surgery, Jacky was diagnosed with an aggressive bone tumor in one pelvic limb. He underwent euthanasia and his owner allowed this study.
The specimen shows that living bone spans through the ostaPek® carbon composite cage in complete ossification, linking the C6-C7 vertebrae of the cervical spine.
ostaPek® ACIF/ACDF cervical interbody fusion
ostaPek® ACIF/ACDF implants are made of ostaPek® carbon composite which is intrinsically osteophilic, no coatings required and its mechanical properties are tailored to ensure primary stability and promote remodeling.
The thin wall cage design enables unparalleled graft to cage volume ratio and the open three-strut cage architecture matches vertebral endplates and lowers the risk of subsidence whilst the large lateral and transverse bone ports allow for optimal fusion.
The ostaPek® ACIF/ACDF cage is available in a number of sizes to provide ease of use, flat or domed, lots of space for graft and optimal match of intervertebral space. Just select the right sized trial, verify the fit and then place the ACIF/ACDF implant filled with the medium of choice.
Gold-markers confirm the implant position and the material is fully radiolucent for high quality diagnostic follow up with CT, MRI and plane x-ray.
