摘要：Pre-operative planning is very important in the process of a Total Hip Arthroplasty (THA) because it is a method for determining the size and optimal implant position. According to experts from Medical Center of Universiti Kebangsaan Malaysia (UKMMC), manual methods are still used to find a suitable implant size for the patient. By using the manual method, any error in template transformation such as rotating and scaling while recording the patient's hip bone radiographs prior to the surgery will lead to errors in determining the size of implant templates. Therefore, a digital method should be developed so that the implant size detection process can be effectively implemented. Manual implant template used by UKMMC is using as the basis for the hip joint implant design. This template is redesign using AutoCAD 2010 software. Template generated in AutoCAD format will be converting to JPEG format so that it can be used in Adobe Photoshop software for colouring and scaling. A total of ten X- ray patients were randomly selected to test the accuracy and effectiveness of the digital implant. Results showed this digital technique predicted stem component size well, with 80% within ±1 size and acetabular component was predicted slightly better with 90% within ±2 component size.
