| Abstract | The morphologic study of the proximal radius was performed with CT scans and reversed engineering teclmiques to measure the anatomical dimensions of the proximal radius in 3D image. The measuring data are derived from 24 Thai cadaveric radii specimens from Siriraj hospital, Bangkok. The proximal radius parameters and new methods of measuring each parameter in 3D-computer graphics were proposed in this study. The statistical and correlation analysis was performed to test morphometric data and study the association between each parameter. According to morphologic analysis in this study based on the parameter used in implant design, the average head diameter of the radial head was about 20 mm. (ranging from 16 mm. to 24 mm.) and diameter of intramedullary canal was about 7 mm. (with ranging from 5 mm. to 9 mm.). The strong correlation coefficients were presented between head diameter and head thickness (r = 0.667) and between head diameter and depth of the concavity surface (r = 0.661 ). Therefore, these parameters were predictable from the value of the head diameter. Categorizing of the standardized radial head implant was performed by means of statistical and correlation analysis. The statistical data at a 95% confidential interval are divided into 5 groups based on the value of parameters. These groups can be utilized for design and manufacturing the radius head prostheses. The evaluation was performed to validate the accuracy and reliability of the measurement and to estimate the deviation of the implant geometry to the real radial head geometry. This study would be the guideline for further development of methods to derive the radius bone parameter based on the 3D model and standardized components design for joint arthroplasty. The resultant design appears to be an alternative for radial head replacement with symmetric shape. However, we still believe that more anatomic consideration would lead to improve elbow joint function after reconstruction. |
