Abstract
- Purpose: This paper proposes a method to convert the measurement of the humerus from conventional two-dimensional (2D) to three-dimensional (3D) measurements and apply it to clinical environments for diagnosis and surgery to improve results. Materials and Methods: In the developed software application, reflection and registration functions were implemented to quantify the difference between both sides of the humerus. Consistent measurements of the humerus were taken by defining the reference axis based on the Principal Component Analysis and aligning the humerus model with respect to the reference axis. Subsequently, the length, volume, the largest cross-sectional area in the head and condyle region, the position ratio of the largest cross-sectional area compared to the longitudinal length in the head and condyle region, and length and angle measurement between markups determined in the head and condyle region were examined. In addition, the automatic extraction of the head and groove, landmarks of the humerus proximal, was implemented. This study applied 40 humerus models (20 males and 20 females) to evaluate the measurements and automatic landmark-determination methods for humerus. Results: The measurements by this software application could provide consistent measurements of the same humerus. In addition, the position ratio of the largest cross-sectional area compared to the longitudinal length in the head and condyle region, proposed through this study, provides a similar ratio regardless of gender and side. Conclusion: The software application developed in this study could measure the humerus and analyze its shape using an objective, reliable, and automatic method in a 3D environment. If the results of this study are applied to real clinical trials, diagnosis, and surgery could be conducted based on objective measurements, and improved results would be achieved. In addition, the study method could be expanded to other fields, such as orthopedics. [ABSTRACT FROM AUTHOR]
