Scoliosis Detection and Assessment

Primary Screening Tests

The American College of Radiology recommends the Adams forward bend test combined with scoliometer measurement for detecting spinal curvature, as these together provide the most reliable clinical assessment, with the Adams Forward Bend Test having a sensitivity of 84.37% and specificity of 93.44%, and the Scoliometer Measurement having a sensitivity of 90.62% and specificity of 79.76% 1, 2

A standing posture assessment should evaluate for shoulder height asymmetry, which is a key indicator of potential scoliosis, according to the American College of Radiology 2
A neurological examination is critical to rule out underlying neurological causes, and should assess for focal neurological deficits, abnormal reflexes, muscle weakness, and pes cavus (high-arched feet), with the American College of Radiology recommending a thorough evaluation 1, 2, 3
A skin examination should check for cutaneous stigmata that might suggest underlying spinal dysraphism, including hemangiomas, hairy patches, dermal appendages, and sinus tracts, as recommended by the American College of Radiology 1

Red flags requiring urgent evaluation include left thoracic curve (atypical pattern), short segment curve, absence of apical segment lordosis/kyphosis, long thoracolumbar curve, rapid curve progression (>1° per month), functionally disruptive pain, focal neurological findings, and male sex, according to the American College of Radiology 1, 2, 4

The differential diagnosis should help distinguish between idiopathic scoliosis (diagnosis of exclusion), syndrome-related scoliosis (Marfan syndrome, Ehlers-Danlos syndrome), and secondary scoliosis (from tumors like osteoid osteoma), with the American College of Radiology recommending a thorough evaluation to determine the underlying cause of scoliosis 1

The American College of Radiology recommends radiography for definitive diagnosis, classification, and treatment planning of scoliosis, as clinical examination alone cannot determine the exact curve magnitude, classify the type of scoliosis, assess for vertebral anomalies, or evaluate curve progression over time 5
Radiography is essential for assessing curve severity, evaluating the risk of curve progression, and differentiating between idiopathic and congenital scoliosis 5
The American College of Radiology suggests that CT may be preferred for visualization of bony malformations and presurgical planning 5
Serial monitoring with radiographs is necessary for skeletally immature patients to evaluate curve progression, with a recommended frequency of no more than once every 6 months 5
