Introduction To
Back Anatomy for Pain Management
An emphasis of our practice is to help each patient understand their body and the pain they are suffering from. Back pain is a condition that will affect 84% of people during their lifetime! Although a vast majority of back pain will resolve within 12 weeks, chronic lower back pain is a condition that can dramatically alter a person’s life. A general approach that I have developed to understand the anatomy is breaking up the body in 4 different buckets:
- Bones
- Nerves
- Muscles
- Tissues
Any of these areas can have pathology or abnormalities that will then cause you pain.

Bones of the Spine (Vertebrae)
The spine (vertebral column) is a complex structure that provides support, movement, and protection for the spinal cord. The bones of the spine include 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 coccyx bones. Most of these bones stack on one another as vertebrae, disk, vertebrae with nerves diving out to innervate the body. These bones are
- Cervical Spine (Neck) – These support the head and allow for movements like nodding and turning.
- Thoracic Spine (Mid-Back) – These vertebrae are unique that they are attached to the ribs
- Lumbar Spine (Lower Back) – There are five vertebrae (L1-L5) in this region and are the largest and bear most of the body’s weight. These are the most affected bones that cause most of the back pain.
- Sacrum and Coccyx (Pelvic Area) – The sacrum consists of five fused vertebrae (S1-S5) that connect the spine to the pelvis, while the coccyx (tailbone) is made of three to five fused bones, providing support when sitting.
Conditions like lumbar spondylosis, scoliosis, compression fracture, and facet joint arthritis can significantly impact these structures, causing chronic pain.
Nerves of the Spine (Spinal Cord and Peripheral Nerves)
The spinal cord is a bundle of nerves that runs through the spinal canal, transmitting messages between the brain and the body.
- Cervical Nerves (C1-C8) – Control movement and sensation in the head, neck, shoulders, arms, and hands.
- Thoracic Nerves (T1-T12) – Control the chest and upper abdominal muscles.
- Lumbar Nerves (L1-L5) – Control the lower abdomen, legs, and parts of the feet.
- Sacral Nerves (S1-S5) – Affect the hips, buttocks, legs, and bladder control.
These spinal nerves branch out from the spinal cord through small openings between the vertebrae called foramina, allowing communication between the brain and different parts of the body. Nerves can be pinched due to herniated disks, facet arthritis, foraminal narrowing etc which will lead to significant pain. These conditions are best treated by our back specialist usually with epidural steroid injection .


Muscles of the Spine
Muscles around the spine help with movement, stability, and posture and can be approached as deep and superficial muscles.
- Deep Muscles – These help with posture and stabilization and include the paraspinals, erector spinae and multifidus.
- Superficial Muscles – These include the trapezius, latissimus dorsi, and rhomboids.
Strong spinal muscles help protect the spine from injury, offload painful pressure to the bones and nerves and support your activities of daily living. Back spasms are common and treated effectively with therapy and muscle relaxant medications. Trigger points can develop in any muscle and oftentimes a trigger point injection can be a useful procedure in relieving pain.
Tissues of the Spine (Discs, Ligaments, and Cartilage)
Several soft tissues help keep the spine flexible and cushioned:
- Intervertebral Discs – These cartilage cushions sit between the vertebrae, absorbing shock and preventing bone-on-bone contact. Each disc has a tough outer layer (annulus fibrosus) and a gel-like inner core (nucleus pulposus).
- Ligaments – These tough bands hold the vertebrae together and maintain spinal stability. Two major structures include anterior longitudinal ligament (which prevents excessive backward bending) and the posterior longitudinal ligament (which limits forward bending).
- Cartilage and Facet Joints – Cartilage lines the small facet joints, allowing smooth movement between vertebrae while preventing excessive twisting or bending.
Discs when weak or damaged can herniate. There are many different types of disc herniation which we will evaluate with MRI imaging. A disc herniation can push on nerves causing significant pain and discomfort. Oftentimes patients will have tremendous benefit from epidural steroid injection to help decrease the swelling and inflammation caused by the disc herniation.

F.A.Q
General Questions
The best treatment depends on the cause of your pain. Our back specialists will evaluate your condition and recommend the most effective non-surgical, minimally invasive options, such as epidural injections, radiofrequency ablation, or spinal cord stimulation.
Yes! Most cases of chronic back pain can be effectively managed with minimally invasive procedures, non-opioid medications, bracing, physical therapy, and lifestyle changes. Surgery is typically considered only when conservative treatments fail or if red flag systems are present.
Treatment effectiveness varies, but many options, such as radiofrequency ablation, nerve blocks, and epidural injections, provide months to years of relief.
You can reduce your risk by maintaining good posture, staying active, strengthening your core muscles, using proper lifting techniques, and avoiding prolonged sitting or heavy lifting without support.
