Patient example. This patient is a 10-year-old female who was Risser 0 with open tri-radiate cartilage at brace initiation. Her thoracic curve measured 44° initially (a). In her brace, her curve decreased to 9.9°, a 77.6% correction from her original curve (b). Thirteen months later, the patient was fitted for a second brace, but new in-brace x-rays were not taken. She was fitted for a third brace 15 months later without confirmation x-rays. This patient was compliant with bracewear; however, for 57.5% of her treatment time, she had an unknown in-brace correction. She ultimately discontinued brace use with a final curve of 63.8°, requiring surgery (c)
