Treatment Plan for Adolescent Thoracolumbar Scoliosis at 19 Degrees
For adolescent thoracolumbar scoliosis with a curvature of 19 degrees, observation and monitoring is the recommended approach, with bracing only indicated if there is documented progression. 1, 2
Initial Assessment and Management
- Upright posteroanterior (PA) and lateral spine radiographs are essential for diagnosing and classifying scoliosis, as recommended by the American College of Radiology 1, 2
- For a 19-degree curve, initial management consists of regular clinical and radiographic monitoring to assess for curve progression 2
- Physical examination should include assessment for shoulder height asymmetry, neurological abnormalities, and skin examination for cutaneous stigmata that might suggest underlying spinal dysraphism 2
Monitoring Protocol
- For skeletally immature patients (Risser 0-3), radiographic follow-up should be performed every 6-12 months to monitor for curve progression 2
- For more skeletally mature patients (Risser 4-5), radiographic follow-up can be extended to every 12-18 months 2
- Limit spine radiographs to once every 12 months for patients at Risser stages 0-3 and every 18 months for patients at Risser stages 4-5 to reduce radiation exposure 2
Indications for Bracing
- Bracing is indicated only if there is documented progression of the curve to 20-25 degrees or more in a skeletally immature patient 2, 3
- Skeletally immature individuals with Cobb angles >20° have >70% likelihood of curve progression, making them candidates for bracing 2
- The literature supports that with proper indications (growing patients with progressive curves between 20° and 45°), a well-designed and adapted brace providing a correction of 50% can stop curve progression in most cases 3
Brace Options If Progression Occurs
- For thoracolumbar curves that progress to >20 degrees, both thoracolumbosacral orthosis (TLSO) and lumbosacral orthosis (LSO) may be considered 4
- LSO demonstrates comparable effectiveness to TLSO in treating main thoracolumbar/lumbar curves, making it a viable clinical option for thoracolumbar scoliosis 4
- TLSO is typically worn 22 hours/day, while Providence orthosis (a nighttime brace) is worn 8-10 hours/night 5
Red Flags Requiring Further Evaluation
- Left thoracic curve, short segment curve, absence of apical segment lordosis/kyphosis, rapid curve progression (more than 1° per month), functionally disruptive pain, focal neurological findings, and male sex are red flags requiring urgent evaluation 1, 2
- Development of new neurological symptoms warrants MRI evaluation 6
- Absence of neurological symptoms does not rule out intraspinal abnormalities, particularly in congenital scoliosis 2
Long-term Considerations
- Even after skeletal maturity, curves exceeding 50 degrees may continue to progress at approximately 1 degree per year, requiring continued monitoring 6, 2
- For curves that remain under 25 degrees through skeletal maturity, the risk of progression in adulthood is minimal 7
- Physical therapy focusing on core strengthening and postural awareness can help manage any symptoms that may develop 6
Common Pitfalls to Avoid
- Excessive radiation exposure from too-frequent radiographs should be avoided by following recommended monitoring intervals 6
- Assuming no progression due to the absence of symptoms and delaying evaluation of new or worsening symptoms 6
- Initiating bracing without documented progression can lead to unnecessary treatment and potential psychological impact 8
