The effectiveness of double-bar correction for pectus excavatum: A comparison between the parallel bar and cross-bar techniques.

ABSTRACT:

Purpose

To compare the effectiveness between parallel bar and cross-bar techniques for treating pectus excavatum.

Methods

A total of 80 patients who underwent parallel bar insertion (group 1) or cross-bar insertion (group 2) were evaluated retrospectively. From the pre- and post-operative chest CT images, vertebral-level-specific pectus indices were defined as the ratio of the maximum transverse diameter to the anteroposterior diameter of the thoracic cavity at a specific vertebral level and measured at 3 levels up (3Up-PI, 2Up-PI, 1Up-PI) and 1 vertebral level down (1Down-PI) from the narrowest point. The effectiveness of double-bar correction was compared between the 2 groups using postoperative vertebral level-specific pectus index changes.

Results
