This study reviews medical records of children and adolescents treated for idiopathic scoliosis (a sideways curve of the spine with no known cause) using the REFLECT™ Scoliosis Correction System.

Inclusion Criteria:

Subjects must meet all of the following criteria to be included in the study:

1. Requires surgical treatment to obtain and maintain correction of idiopathic scoliosis
2. Skeletally immature
3. Major Cobb angle of 30° and 65°
4. Bone structure adequate to safely accommodate screw fixation
5. Failed bracing treatment and/or intolerant to brace wear
6. Treated with the REFLECT™ Scoliosis Correction System, using single or dual REFLECT cord(s) per curve
7. Availability of medical and radiographic records evaluating the product under study preoperatively through a minimum of 12 months postoperative

Exclusion Criteria:

Patients were excluded from the study if they met any of the following conditions:

1. Presence of any systemic infection, local infection, or skin compromise at the surgical site
2. Prior spinal surgery at the level(s) to be treated
3. Known poor bone quality, defined as a T-score of -1.5 or less
4. Any other medical or surgical condition which would preclude the potential benefit of spinal surgery, such as coagulation disorders, allergies to the implant materials, or patient unwillingness or inability to cooperate with postoperative care instructions

The study population consists of skeletally immature pediatric and adolescent patients with progressive idiopathic scoliosis who were treated surgically with the REFLECT™ Scoliosis Correction System as part of routine clinical care. Eligible patients had a major spinal curve between 30° and 65°, required surgical correction after failing or being unable to tolerate bracing, and had adequate bone quality to support screw fixation.

This is a multicenter, international retrospective cohort including approximately 100 patients treated at participating institutions in Germany, Turkey, and the United States. The cohort includes patients treated with either 4.0 mm or 5.0 mm REFLECT cords, using single or dual cords per curve, with at least 12 months of postoperative clinical and radiographic follow-up available for review.
