Indications and patient selection
The ApiFix system is indicated for use in patients with adolescent idiopathic scoliosis meeting the following criteria:
- Single curves classified as Lenke 1 (thoracic major curve) or Lenke 5 (thoracolumbar/lumbar major curve)
- Cobb angle 35 – 60 degrees
- Curves reduce to ≤ 30 degrees on lateral side-bending x-rays
- Kyphosis < 55 degrees (measured from T5 to T12)
Use of the ApiFix system in patients with curves of lower magnitudes (i.e., < 40 degrees) is based on the risk for curve progression.
