Study finds, Lack of in-brace x-rays in compliant AIS patien
In-brace correction and brace compliance with thoraco-lumbo-sacral orthotic (TLSO) braces are associated with successful treatment of adolescent idiopathic scoliosis (AIS). This paper compares patients who had consistent radiographic documentation of in-brace correction to those who did not.

All skeletally immature (Risser 0-2) patients were treated for AIS (25-45°) with full-time TLSO braces that had compliance temperature monitors. All patients wore their braces at least 12 h a day. Brace failure was defined as curve progression to a surgical magnitude (more than 50°). All patients were followed until brace discontinuation.

--90 patients with an average age of 12.1 years, Risser grade 0 (0-2), BMI percentile 48.5, and daily brace wear of 16.5 h/day were treated for 24.3 months.

--Patients went through 1.7 braces on average. 42 patients had some amount of brace time with an unknown in-brace correction, which, on average, was 66.1% of their total treatment course.

--On univariate analysis, patients that did not have a repeat in-brace x-ray with major brace adjustments or new brace fabrication tended to be more skeletally immature, wear more braces throughout their treatment, were treated for a longer period of time, and failed bracing more often.

Finally, patients who did not have fresh in-brace x-rays with major brace changes and/or new brace construction were 3.1 times more likely to fail bracing than those who did.
