한국인의 견관절에서 상완골 골두 인공관절 치환술의 3차원 시뮬레이션

Abstract

Introduction: This study was done to evaluate the accuracy of the commercially available prosthetic designs in replicating the Korean humeral head anatomy. Methods: CT scan data of 24 Korean patients was taken and their 3D CAD models were generated. Then humeral head prosthetic design of a Bigliani-Flatow (BF) shoulder system was used to do simulation humeral arthroplasty surgery and the humeral head size having the perfect fit were found out. This data was compared with the known literature. Results: All the Korean heads were perfectly matched by one of the sizes available. The average head size was 48.5mm and the average head thickness was 23.5mm. The results match reasonably well with the previous data available in the literature. Conclusions: Korean humeral head anatomy can be recreated reasonably well by the commercially available humeral head prosthetic designs and their dimensions are similar to that of the published literature.
