Intervertebral hernias are a common manifestation of degenerative spinal diseases .
The main symptoms of spinal hernia
- pain in the neck or lower back that radiates to the arm or leg,
- predominantly of a pulling nature,
- increases in an upright position and when leaning forward,
- numbness in the limb,
- a decrease in strength in it.
The above symptoms are observed when a herniated disc compresses a nerve root.
Sometimes a herniated disc does not compress a nerve, but it can cause constant “mechanical” pain in the spine. It is worse in an upright position and when leaning forward. It is caused by direct damage to the disc by the degenerative process.
To date, a number of studies have been conducted on the safety and effectiveness of the DIAM device in the treatment of spinal canal narrowing and herniated intervertebral discs at the lumbar level .
The DIAM device consists of a silicone part in the shape of the letter H and a polymer coating. It is installed between the spinous processes in the lumbar spine, relieving the posterior parts of the intervertebral disc. This device helps to reduce pressure on the nucleus pulposus and the likelihood of recurrence of herniated discs after surgery, enlarge the intervertebral foramina through which the nerve roots exit, and reduce the negative impact of rotational movements in the lumbar spine on the fibrous rings. Evidence-based medicine data confirm a significant reduction in recurrence of herniated discs after the installation of such prostheses and an improvement in the biomechanical properties of the operated segment.
DIAM is a kind of movable disc prosthesis and interspinous ligament substitute at the same time. The device is easily installed through a small skin incision and has virtually no complications or side effects when properly selected indications.
