L2–L3 Discitis

Discitis refers to inflammation and, most often, infection of the intervertebral disc space. When it occurs at the L2–L3 level, it affects the cushion-like disc between the second and third lumbar vertebrae, causing local pain, stiffness, and sometimes nerve irritation. Discitis can arise from bacterial spread via the bloodstream, post-surgical contamination, or nearby bone infection, leading to disruption of disc nutrition and integrity, inflammatory cell infiltration, and pain [Patient Info][pmc.ncbi.nlm.nih.gov].

Pathophysiology

Discitis represents either infectious or non-infectious inflammatory destruction of the intervertebral disc and adjacent endplates. In adults, the avascular nature of the mature disc renders it relatively resistant to infection; however, bacteria (most commonly Staphylococcus aureus) can seed the disc via small nutrient vessels at the endplates, leading to bacterial proliferation, enzymatic digestion of disc fibers, and local immune response. Over days to weeks, inflammatory cells release cytokines and proteolytic enzymes that degrade the disc matrix, erode endplates, and may extend to paraspinal tissues. In non-infectious (aseptic) discitis, autoimmune or degenerative mechanisms trigger a similar inflammatory cascade without a detectable pathogen.

Types of L2–L3 Discitis

1. Acute Pyogenic Discitis
   – Caused by bacterial invasion (often S. aureus) with rapid onset of symptoms over days.

2. Subacute Bacterial Discitis
   – Slower course (weeks), sometimes due to less virulent organisms (e.g., coagulase-negative staphylococci, Enterobacteriaceae).

3. Tubercular Discitis (Pott’s Disease)
   – Mycobacterium tuberculosis involvement; often spreads from vertebral body to disc, more indolent.

4. Fungal Discitis
   – Rare; pathogens include Candida, Aspergillus, especially in immunocompromised.

5. Parasitic Discitis
   – Extremely rare; e.g., Schistosoma species in endemic areas.

6. Aseptic (Sterile) Discitis
   – Autoimmune or degenerative inflammation without identifiable pathogen; may follow discography or endplate injury.

7. Postoperative (Iatrogenic) Discitis
   – Occurs after lumbar surgery, injection, or discography due to direct inoculation.

8. Pediatric (Juvenile) Discitis
   – Often aseptic; children present with refusal to walk, low-grade fever, typically involving L2–L3.

2. Palpation of Spinous Processes
   Applying gentle pressure over L2–L3 spinous processes to elicit focal tenderness.

3. Percussion Tenderness Test
   Lightly tapping the vertebral column over L2–L3; severe pain suggests inflammation.

4. Assessment of Lumbar Range of Motion
   Asking the patient to flex, extend, and laterally bend; reduction indicates pain source.

5. Evaluation of Paraspinal Muscle Tone
   Palpating for muscle spasm or guarding adjacent to the L2–L3 disc.

6. Neurological Screening
   Testing motor strength (especially quadriceps), sensory exam in L3 dermatome, and reflexes (patellar).

B. Manual Provocative Tests

7. Straight Leg Raise (SLR) Test
   With patient supine, lifting the straightened leg to stretch L3 nerve root; pain suggests nerve involvement.

8. Bowstring Test
   Variation of SLR; knee flexion at the point of maximal SLR pain reduces stretch, then re-extension + popliteal pressure reproduces pain.

9. Femoral Nerve Stretch (FNS) Test
   With patient prone, extending the hip to stretch L2–L4 roots; anterior thigh pain indicates nerve irritation.

10. Kemp’s (Quadrant) Test
    Standing patient extends, rotates, and side-bends toward the painful side; reproduction of back or leg pain suggests facet or disc pathology.

11. Slump Test
    Seated patient slumps forward with neck flexion and leg extension; reproduction of symptoms implies neural tension.

    Analysis of biopsy specimen to detect granulomas (tubercular), fungal elements, or neoplastic cells.

D. Electrodiagnostic Studies

19. Electromyography (EMG)
    Detects denervation changes in muscles supplied by L3 root.
