The Basic Anatomy of Our Lower Back

The lower back is composed of several muscles, nerves, and ligaments that protect your spine and help you keep your balance. The sacroiliac joints connect the base of the spine (sacrum) to the hip bones (pelvis). The lower back’s strong ligaments and muscles support these joints.

Ligaments in the lumbar area are located between the vertebrae and connect the muscles to the spine and hip bone:

  • Sacrotuberous ligaments: Connects the legs with the trunk, biceps femoris, and perineum to the thoracolumbar fascia, and spine. It also assists in pelvic stability and prevents the tipping of the sacrum.

Soft tissues in the lower back are mostly composed of vertebral discs that protect our spine and give it mobility. However, in the lower back you can find the thoracolumbar fascia. It consists of multiple layers of crosshatched collagen fibres that cover the back muscles in the lower thoracic and lumbar area before passing through these muscles to attach to the sacrum.

Muscles in the lumbar area include the piriformis, deep gluteal muscles, gluteus, hip external rotators, hamstrings, and latissimus dorsi.

Several nerves coincide in the lumbar area:

  • L1 spinal nerve: provides sensation to your groin regions and contributes to the movement of your hip muscles.
  • L2, L3, and L4 spinal nerves: provide sensation to the frontal part of your thigh and the inner side of your lower leg. These nerves also control movements of your hip and knee muscles.
  • L5 spinal nerve: provides sensation to the outer side of your lower leg, the top part of your foot, and in between your first and second toes. This nerve also controls your hip, knee, foot, and toe movements.

Typical Causes of Lower Back Injuries and Pain

Unfortunately, due to the natural movement of the hips, we may not notice when we are overworking our lower back. Force placed on the various components of the lumbar area–muscles, nerves, ligaments, and other connective tissues–due to inadequate movement can lead to lower back pain.

The most common lower back injuries that lead to lower back pain include sprains, strains, and tears. Alongside pain, individuals may also experience stiffness, restricted movements, difficulty in performing routine activities, and pain down your leg.

Lower back injuries can take many forms; sometimes an injury happens suddenly or gradually after years of overuse. Causes of lower back injury and pain include:

I. Overuse Injuries

Overuse injuries occur when continued stress is placed on a specific joint, muscle, or other tissue in the lumbar area, often caused by repetitive activities such as sports or even manual labor. Examples of overuse injuries include:

  • Inflammation
  • Muscle strain
  • Nerve strain

II. Sudden (Acute) Injuries

Sudden injuries can occur at any moment, whether because of a fall, a direct blow to the hip, or any sort of improper movement of the hip can cause severe pain suddenly.

Acute injuries include:

  • Bruises
  • Contusions
  • Pulled muscles (strains)
  • Broken bones including fractures or breaks
  • Nerve damage or pinching
  • Ligament injuries

III. Other Causes of Lower Back Pain

Alongside sudden injuries or overuse injuries, individuals may deal with muscle pain as a result of:

  • Poor posture
  • Sitting for too long
  • A breakdown of the cartilage in your hip
  • Calcium buildup in the hip
  • Herniated discs in the lumbar spine
  • Leg strain that pulls muscles affecting the lower back
  • Pinched nerves
  • Infections in the bone or joints
  • Abuse
  • Osteoporosis

More on the Various Types of Lower Back Injuries a Pain Management Clinic Treats

Lumbar Strain

A lumbar strain is an injury to the lower back. This results in damaged tendons and muscles that can spasm and feel sore. These types of lower back injuries are common in those who play sports.

Soft Tissue Damage

Soft tissue injuries are the most common in the lumbar area. Most of the time, these injuries involve strain and sprains in the lower back muscles but can also include herniated discs.


Direct blows to the lower back, such as those suffered from a traumatic event or a fall on a hard surface, can lead to fractures or breaks in the sacrum and hip bones.


Usually caused when a herniated disc or bone spur in the spine presses on the nerve.
Pain originates in the spine and radiates down the back of the leg. Sciatica typically affects only one side of the body.
