Chest wall deformities such as pectus excavatum can cause the sternum to invert, thus increasing the index. Hi is defined as the ratio of transverse to anteroposterior chest wall diameters, determined from a single axial computed tomography (ct) scan at the point of maximal pectus deformity.

The haller index (hi), also known as the pectus index, is a simple mathematical way to assess and describe the chest cage on ct of the thorax and is used in the detection and pre/postoperative assessment of pectus excavatum 1,5. The haller index (hi), or pectus index, was proposed by haller et al 1 in 1987 as an objective measure of pectus excavatum severity.

They Designed A Novel Computerized Approach Involving Three Steps:

For consistency, therefore, it is recommended to calculate the largest haller index in pectus excavatum patients by obtaining the ap diameter at the deepest point of the sternum 1. Therefore, we performed a diagnostic analysis to assess the ability of hi to separate patients with pectus excavatum from healthy controls compared to a novel index. Chest wall deformities such as pectus excavatum can cause the sternum to invert, thus increasing the index.
