초록

The aim of this study is to develop a humeral Intramedullary fixation nail (HIFN) suitable for Korean people. In this study, CT images were obtained from 72 Korean cadaveric humeral bones and 3D Korean humeral bone models were reconstructed based on the CT images to investigate anatomical characteristics. Major design parameters of HIFN were selected using the morphological measurement information of the Korean humeral bone models. Through finite element analysis and mechanical tests, the developed HIFN prototype was compared with the Polarus HIFN ($ACUMED^{(R)}$, USA), and it was found that the HIFN prototype showed similar and/or superior mechanical performance compared to the Polarus HIFN. Also, clinical validation for the HIFN prototype was carried out to check predictable troubles in surgical operations. Finally, optimal design modification was proposed to prevent the possible axillary nerve injury due to the locking screw system of the HIFN prototype.
