Purpose:
The purpose of this study is to measure the effectiveness of compressive orthotic brace therapy for the treatment of pectus carinatum using an adjusted Haller Index (HI) measurement calculated from 3D body scan (BS) images.
Methods:
Pediatric patients with pectus carinatum were treated with either compressive orthotic bracing or observation. An adjusted BS Haller index (HI) was calculated from serial 3D BS images obtained on all patients. Medical records were evaluated to determine treatment with bracing and brace compliance more than 12hours daily. Compliant patient measurements were compared to non-compliant and non-brace groups.
Results:
Forty patients underwent compressive orthotic bracing, while ten were observed. Twenty-three patients were compliant with bracing, and seventeen patients were non-compliant. Compliant patients exhibited an 8.2% increase, non-compliant patients had a 1.5% increase, and non-brace patients exhibited a 2.5% increase in BS HI. The change in BS HI of compliant patients was significantly different compared to non-brace patients (p=0.004) and non-compliant patients (p<0.001).
Conclusions:
Three dimensional BS is an effective, radiation free, and objective means to evaluate patients treated with compressive orthotic bracing.
