Posterolateral Lumbar Disc Bulge

Posterolateral bulges are among the most common imaging findings in patients with low back pain? and sciatica?, since this location lies adjacent to the neural foramen and lateral recess, where nerve roots exit the spinal canal USA Spine CareAO Foundation Surgery Reference.

Anatomy? of the Lumbar Intervertebral Disc

Gross Structure

Each lumbar intervertebral disc is a fibrocartilaginous joint between adjacent vertebral bodies, consisting of:

1. Annulus fibrosus: Concentric lamellae of type I collagen fibres arranged at alternating angles (~60° to the vertical axis) providing tensile strength.

2. Nucleus pulposus: Central gelatinous core rich in proteoglycans and water (70–90% in youth), evenly distributing axial loads.

3. Vertebral endplates: Thin hyaline cartilage? layers (<1 mm) anchoring the disc to vertebral bodies and mediating nutrient diffusion Wheeless’ Textbook of OrthopaedicsRadiopaedia.

Location

Lumbar discs lie between the bodies of L1–L2 through L5–S1, making up ~25–33% of spinal column height and contributing to lumbar lordosis Wheeless’ Textbook of OrthopaedicsPhysiopedia.

Origin and Insertion

• Origin: Embryologically derived from the notochordal and surrounding mesenchyme; annular lamellae begin forming by week 10 of gestation?.

• Insertion: Annulus fibres anchor into the epiphyseal rings at the vertebral endplates; nucleus pulposus interfaces with endplates but has no direct bony insertion Wheeless’ Textbook of OrthopaedicsDeuk Spine.

Blood Supply

Intervertebral discs are largely avascular.

• Outer annulus: Supplied by small branches from segmental arteries? at the disc–bone junction.

• Inner annulus & nucleus: Rely entirely on diffusion across endplates from vertebral body capillaries? KenhubSamarpan Physiotherapy Clinic.

Nerve Supply

• Recurrent? meningeal (sinuvertebral) nerves: Innervate outer annulus and posterior longitudinal ligament?.

• Sympathetic fibres: Provide minor innervation near anterior annulus.
  Only the outer 1–3 lamellae of the annulus contain nociceptive fibres, explaining why deep disc lesions may be painless Via Medica JournalsScienceDirect.

Functions

1. Shock? absorption: Nucleus resists compressive forces, converting them into radial stresses.

2. Load distribution: Evenly transmits axial loads across vertebral endplates.

3. Spinal mobility: Permits flexion, extension, lateral bending, and rotation.

4. Spacing: Maintains intervertebral foramen height to protect nerve roots.

5. Energy storage: Acts like a hydrostatic cushion, returning to shape after loading.

6. Stability: Alongside facet joints, resists shear forces and torsion Wheeless’ Textbook of OrthopaedicsPhysiopedia.

Types of Disc Bulges

Disc bulges can be classified by shape and extent:

1. Circumferential (diffuse) bulge

   Involves ≥50% of the disc circumference, uniformly extending beyond vertebral margins Radiopaedia.

2. Broad-based bulge

   Involves 25–50% of the circumference, often asymmetrically thickened annulus Radiopaedia.

3. Focal bulge

   Involves <25% of the circumference but extends >3 mm beyond vertebral margins, more likely to impinge nerve roots RadiopaediaVerywell Health.

4. Posterolateral bulge

   Localized? to the posterolateral quadrant, most common, with high risk of lateral recess or foraminal nerve compression USA Spine CareAO Foundation Surgery Reference.

FAQs

1. What exactly causes a posterolateral disc bulge?
