Herniated discs, commonly referred to as “slipped discs”, are a prevalent health concern that can lead to a myriad of symptoms including pain, numbness, and inflammation. This occurs when the jelly-like substance inside a spinal disc ruptures and presses against nearby nerves.
Understanding the Spinal Disc
The spine is made up of vertebrae or spinal bones. Between these vertebrae are discs that act as cushions. When the jelly-like filling of a disc breaks through its outer shell, known as the annulus, it can bulge out. This condition is often termed a herniated disc. Another related condition is a bulging disc. This happens when the disc’s outer wall weakens and protrudes, but doesn’t rupture. It’s crucial to know that a herniated disc may actually start as a bulging disc, which later ruptures due to significant pressure.
Symptoms and Diagnosis
When a herniated disc compresses a spinal nerve, symptoms may include pain radiating down the arms or legs, muscle weakness, and difficulty with repetitive motions. For instance, a 28-year-old man once developed pain that radiated down his right leg. His examination revealed weakness in right knee flexion, an absent right ankle reflex, and sensory loss in certain parts of the right foot and leg.
Most herniations occur in the lower spine, specifically between the 4th and 5th lumbar vertebrae and between the 5th lumbar vertebra and the sacrum. Notably, the L5 nerve travels down the central canal at levels L4-5 and above, eventually emerging between the L5 and S1 vertebrae. This anatomical fact is pivotal because a herniation at the L4/5 disc damages the L5 nerve root, and a herniation at the L5/S1 disc affects the S1 root. This is critical knowledge for anyone studying or dealing with spinal health.
Treatment Options
Microdiscectomy is a common minimally invasive surgical procedure for treating herniated discs. It’s particularly useful when a herniated disc leads to nerve compression. Another common treatment method is the use of epidural steroid injections. These injections can be effective in providing permanent pain relief for patients with new disc herniations. For those with chronic pain or recurrent herniations, the goal is to achieve pain relief for a duration of three to six months or even longer. However, like all treatments, there are risks associated with epidural steroid injections, and it’s essential to be informed about them.
