OBJECTIVES: The main purpose of this study was to design, manufacture and implant a customized three-dimensional (3D) printed, intervertebral spacer to treat disc-associated cervical spondylomyelopathy (DACSM) in dogs. This study also used advanced imaging to assess implant movement, subsidence and interbody fusion.

ANIMALS: Two client-owned dogs with DACSM.

Introduction  Biomechanical properties of four different ventral surgical procedures at the canine fourth-fifth cervical (C4–C5) vertebral motion unit (VMU) were assessed and compared with the intact C4–C5 VMU.

Category: Spine

OBJECTIVE: To define boundaries of minimally invasive integrated endoscopic hemilaminectomy at 4 sites in the canine thoracolumbar spine.

STUDY DESIGN: Experimental, randomized cadaveric study.

ANIMALS: Six cadaver dogs that had been humanely euthanized for reasons unrelated to this study.

Category: Spine

OBJECTIVE: To evaluate safety and efficacy of a novel technique for cervical stabilization.

STUDY DESIGN: In vivo experimental.

ANIMALS: Four normal adult quarterhorse crossbreed horses (2-4 years of age, > 250 kg).

Low back pain, related to degeneration of the intervertebral disc (IVD), affects millions of people worldwide. Clinical studies using oral cyclooxygenase-2 (COX-2) inhibitors have shown beneficial effects, although side-effects were reported. Therefore, intradiscal delivery of nonsteroidal anti-inflammatory drugs can be an alternative treatment strategy to halt degeneration and address IVD-related pain.

OBJECTIVES: To describe a surgical technique using bilateral twisted string-of-pearls locking plates for lumbosacral fracture-luxation in dogs and cats.

Notochordal cells (NCs) reside in the core of the healthy disc and produce soluble factors that can stimulate nucleus pulposus cells (NPCs). These NC-derived factors may be applied in intervertebral disc regeneration for treatment of low-back pain. However, identification of the active soluble factors is challenging. Therefore a novel approach to directly use porcine NC-rich NP matrix (NCM) is introduced.
