Management of Thoracolumbar Spine Pain in a 16-Year-Old
For a 16-year-old with thoracolumbar spine pain without trauma, red flags, or neurological symptoms, imaging is not indicated initially—proceed directly with conservative management including physical therapy and NSAIDs. 1
Initial Clinical Assessment
Determine if this is traumatic or non-traumatic pain:
- If there is any history of trauma (fall, sports injury, motor vehicle collision), this patient requires imaging evaluation per trauma protocols 1
- If there is no trauma history, this is atraumatic back pain and imaging is typically not warranted initially 1
Red Flags Requiring Immediate Imaging
Screen for these specific red flags that mandate early imaging: 1
- Neurological deficits: Weakness, numbness, bowel/bladder dysfunction, or myelopathy
- Cancer history or suspicion: Known malignancy, unexplained weight loss, night pain
- Infection signs: Fever, recent bacterial infection, immunosuppression, IV drug use
- Inflammatory arthritis symptoms: Morning stiffness >30 minutes, improvement with exercise, alternating buttock pain (suggesting spondyloarthritis)
- Prior thoracic spine surgery or fusion
- Chronic steroid use (increases fracture risk even without significant trauma)
Non-Traumatic Back Pain Without Red Flags
This represents the most common scenario and does not require imaging: 1
- Thoracic back pain without red flags is typically self-limiting and responsive to conservative management 1
- Imaging provides no clinical benefit in this population and often reveals incidental findings that do not correlate with symptoms 1
- Thoracic disc abnormalities (herniations, bulges, annular fissures) are commonly seen in asymptomatic patients and do not predict pain 1
- Facet joint degenerative changes on imaging do not correlate with pain presence or severity 1
Conservative management approach: 1
- NSAIDs or acetaminophen for pain control
- Physical therapy with focus on posture, core strengthening, and range of motion
- Activity modification avoiding prolonged static positions
- Reassurance about the benign, self-limiting nature of most thoracic back pain
When to Consider Imaging After Conservative Trial
If pain persists beyond 4-6 weeks despite conservative management AND there are minor risk factors, consider imaging: 1
- Minor risk factors include: age-inappropriate pain patterns, pain that awakens from sleep, or subtle constitutional symptoms
- In this scenario, MRI thoracic spine without contrast is the preferred modality for evaluating soft tissue, disc, and bone marrow pathology
Traumatic Mechanism Present
If trauma history exists, imaging indications differ significantly: 1
- High-risk criteria requiring imaging: Midline thoracolumbar tenderness, high-energy mechanism (motor vehicle collision, fall from height), or inability to perform adequate examination (altered consciousness, intoxication, distracting injury) 1
- CT thoracic and lumbar spine without contrast is the gold standard for traumatic injury with 94-100% sensitivity for fractures 1, 2
- Clinical examination has only 48-75% sensitivity for thoracolumbar fractures, making imaging essential in high-risk trauma patients 1
- Screen the entire spine when trauma is present, as 20% of spine injuries have a second noncontiguous fracture 1
Common Pitfalls to Avoid
- Do not order imaging for uncomplicated thoracic back pain without red flags—this leads to unnecessary radiation exposure, cost, and often incidental findings that complicate management 1
- Do not assume all back pain in adolescents is musculoskeletal—always screen for red flags including infection, malignancy, and inflammatory conditions 1
- Do not miss referred pain from visceral sources—thoracic pain can originate from intrathoracic, renal, vascular, or gastrointestinal pathology 1
- Do not apply adult osteoporotic fracture risk criteria to this age group—the 16-year-old does not have age-related fracture risk unless on chronic steroids or has underlying bone disease 1
Specific Pain Pattern Considerations
Thoracolumbar junction pain (T12-L2 region): 3, 4
- Can present with referred pain to the posterior iliac crest or pseudo-visceral symptoms
- Diagnosed clinically by tenderness over spinous processes or facet joints at the thoracolumbar junction
- May respond to targeted interventional treatments if conservative management fails after appropriate trial
