Spinal implants are incredibly important components of modern medical care. They are crucial in providing both acute and long-term support to those recovering from injuries, chronic back pain, or other degenerative conditions of the spine. This guide will discuss the different kinds of spinal implants, their purposes and the causes they can be used to address.
Types of Spinal Implants
Rod & Screw System
The rod and screw system is a frequently used spinal implant used to stabilize areas of the spine. It is composed of rods that are designed to support the curvature of the spine, and screws that are drilled into the vertebrae and connected to the rods. This system allows for a more dynamic and adaptable movement, allowing patients to still engage in normal motions like bending and stretching.
Interbody Fusion Cage
Interbody fusion cages are commonly used for a technique of spinal surgery called Interbody fusion. This technique is used to join two disconnected vertebrae for spinal stability. The cage itself acts as a stabilizing spacer, keeping both vertebrae in place after the procedure is complete. Interbody fusion cages can be made of titanium and other synthetic materials.
Artificial Disc
Artificial discs are used to replace natural disc, which hold vertebrae together while allowing movement between discs. When replaced due to injury, disease, and age-related degeneration, an artificial disc is used as a substitute. Artificial discs are made of synthetic materials, generally a combination of steel, carbon fiber, and hard plastic, and act a joint between vertebrae, allowing for a more natural movement compared to other spinal implants.
Dynamic Stabilization Systems
Dynamic stabilization systems are designed to hold the vertebrae of the spine firmly in place, providing relief from pain and reducing unwanted motion. The system is mostly composed of lightweight parts and wires that are attached with screws and anchors to the affected vertebrae. This provides a flexible and adjustable support for the spine.
Kyphoplasty
Kyphoplasty is a procedure designed to relieve pain in patients suffering from spinal compression fractures. Unlike other surgery techniques, kyphoplasty is a minimally-invasive surgery, meaning that instead of a large incision, small punctures are made. A balloon is then inserted into the spine and inflated to restore the lost vertebrae height, followed by injecting a cement-like mixture into the space to provide additional stability.
Spinal Cord Stimulators
Spinal cord stimulators are electronic devices implanted directly into the spine which emit electrical signals in order to block pain signals. These stimulators are used to treat a broad range of chronic pain conditions, including back pain and neck pain. Additionally, it can often achieve therapeutic effects without an associated increase in pain medication.
Cervical Artificial Disc
A cervical artificial disc is a device specifically designed for the neck and cervical vertebrae, allowing for mobility in the area while still providing support and preventing unwanted motion. This device is often used to treat conditions resulting from herniated discs or other disc-related injuries, in addition to chronic neck and arm pain.
Vertebral Body Tethering
Vertebral body tethering is a method of spinal injury treatment intended to prevent unwanted spinal movements that occur in symptomatic patients. The device consists of a strong flexible cable connected to a single vertebra, preventing it from shifting or bending in an unnatural position.

What is the most common spinal implant?
The most common spinal implant is the rod and screw system, which is composed of rods to support the curvature of the spine and screws drilled into the vertebrae to connect the rods.
Are spinal implants safe?
Spinal implants are generally considered to be safe and effective, and many have a track record of successful use in medical practice.
How long do spinal implants last?
Spinal implants are designed to last for long periods of time, although their longevity is largely dependent on the implant material. Generally, they can last anywhere from 10-20 years depending on the type of implant and individual patient usage.

Final Words
Spinal implants are vital components of modern medical care, and they can be used to help patients recover from injuries and manage a number of chronic pain conditions.
