Treatment for 27-Degree Scoliosis in a 20-Year-Old Woman
For a skeletally mature 20-year-old woman with a 27-degree scoliotic curve and back pain, observation with symptomatic pain management is the appropriate treatment—no bracing or surgery is indicated at this curve magnitude. 1, 2
Treatment Algorithm Based on Curve Magnitude
Why No Active Intervention is Needed
Curves under 40-45 degrees in skeletally mature patients should be observed, as surgical intervention is reserved for curves exceeding 50 degrees due to progression risk. 1, 3
At 27 degrees, this patient falls well below any surgical threshold, which begins consideration only at 45-50 degrees and is typically recommended above 50 degrees. 1, 2
Bracing is not indicated in skeletally mature patients—bracing is a treatment for skeletally immature adolescents with curves between 20-45 degrees who still have growth potential. 2, 4 Since this patient is 20 years old, she is skeletally mature and bracing will not alter curve progression.
Progression Risk at This Curve Magnitude
Curves under 40 degrees in skeletally mature patients have minimal progression risk and do not typically progress at the concerning rate of 1 degree per year seen with curves over 50 degrees. 1, 3
The natural history data shows that curves exceeding 50 degrees may progress at approximately 1 degree per year after skeletal maturity, but curves in the 20-30 degree range are generally stable. 1, 2
Management of Associated Back Pain
Pain is Not an Indication for Surgery at This Curve Magnitude
Back pain alone does not warrant surgical intervention unless the curve exceeds 50 degrees AND pain is intractable despite conservative measures. 1
The presence of pain requires evaluation to ensure it is musculoskeletal in nature and not related to neurological compromise. 5
Red Flags Requiring Advanced Imaging
Obtain MRI of the thoracic/lumbar spine without contrast if any of these features are present: 2, 5
- Focal neurological findings (weakness, abnormal reflexes, sensory changes)
- Myelopathy signs (spasticity, hyperreflexia, positive Babinski, bladder dysfunction)
- Functionally disruptive pain not responding to conservative measures
- Left thoracic curve pattern (atypical)
- Rapid progression of symptoms
If none of these red flags are present, no advanced imaging is needed—plain radiographs are sufficient for monitoring. 5
Monitoring Protocol
Radiographic Surveillance
Serial radiographs every 12-18 months to monitor for any progression, though progression is unlikely at this curve magnitude in a skeletally mature patient. 2, 5
The American College of Radiology recommends limiting radiation exposure by adhering to these maximum surveillance frequencies. 2
When to Escalate Care
Refer to orthopedic spine specialist if: 5
- Curve progresses beyond 40-45 degrees on serial imaging
- Development of new neurological symptoms
- Pain becomes functionally disruptive and unresponsive to conservative treatment
- Documented progression despite skeletal maturity
Conservative Pain Management
Symptomatic treatment with NSAIDs, physical therapy focusing on core strengthening and postural exercises, and activity modification as needed for pain control. 5
Physical therapy and exercises have some evidence for symptom management in adolescent idiopathic scoliosis, though the evidence is not robust. 6
Critical Pitfalls to Avoid
Do not assume pain is solely from the scoliosis—thoracic disc herniations can present with burning pain and may coexist with scoliosis. 5
Do not order MRI routinely without red flags—advanced imaging is not indicated and unlikely to change management in the absence of neurological symptoms. 5
Do not recommend bracing in a skeletally mature patient—this is ineffective after growth plates have closed. 2, 4
Do not consider surgery at 27 degrees—this is far below any accepted surgical threshold and would be inappropriate. 1, 2
