Current and Future Central Nervous System Surgery-Part 1: Cervical Spinal Cord Compression.

Current surgical treatments for cervical spinal cord compression in horses predominantly use ventral cervical stabilization, but new imaging technologies and surgical methods are expanding and improving options for addressing various spinal cord problems.

Overview of Current Surgical Approaches

• Ventral cervical stabilization is currently the primary surgical approach for horses suffering from spinal cord compression.
• This method focuses on stabilizing the cervical vertebrae from the ventral (front) side to relieve pressure on the spinal cord.

Advancements in Imaging

• Volumetric imaging techniques, such as 3D CT or MRI, provide a more comprehensive visualization of the central nervous system structures.
• These imaging advances reveal that spinal cord compression may occur in more varied ways than previously thought, not only through ventral compression.
• This enhanced diagnostic capability allows for better identification of compressive lesions and their exact locations and characteristics.

Emerging Surgical Technologies

• Minimally invasive instrumentation is being developed to reduce surgical trauma and recovery time while maintaining procedural effectiveness.
• Computer-assisted surgery offers precise guidance in placing implants and performing decompression, improving accuracy and safety.
• Such approaches expand the surgical options for conditions like cervical vertebral compressive myelopathy (spinal cord disease due to vertebral compression), radiculopathy (nerve root compression), vertebral fractures, and masses within or around the spinal canal.

Novel Surgical Techniques and Implant Systems

• Articular process joint fixation targets specific joints within the cervical vertebrae to stabilize and decompress affected areas.
• Targeted decompression techniques focus on precise relief of pressure on the spinal cord or nerve roots rather than broad or generalized decompression.
• Innovative implant designs are being introduced to better accommodate varied spinal pathologies and spinal anatomy.

Future Directions and Potential Benefits

• As new technologies and surgical methods are validated through research and clinical use, they have the potential to offer more tailored and effective treatments for spinal disorders in horses.
• The combination of advanced imaging and precise surgical tools may broaden treatment options beyond traditional ventral stabilization to address complex or atypical cases.
• Ultimately, these advancements aim to improve surgical outcomes by reducing complications, speeding recovery, and better preserving neurologic function in horses with cervical spinal cord compression.
