Title : Computer Aided Orthopaedic Surgery
Project detail : IRPA-EA no: 04-02-04-0496-EA001
Amount : RM 204,560.00
Period : 36 month

This study is focused on the decision support system (DSS) for assisting the orthopedic surgeon in determination of the best of the Cobb angle correction and the force to be used for rotating and straightening the deformed thoracic spine. The result of the study will provide a DSS for assisting the surgeon in determine the degree of the thoracic curve fixation, and also as a guide to reduce the failure of the scoliosis operation through the calculation of the force to be used for rotating the vertebrae, straightening the vertebrae, and the maximum degree to be corrected. Basically the system development will be separated into four phases:

First Phase: Information Collection

-the x-ray images will be collected from Hospital Kuala Lumpur and the interview with orthopedic surgeon will be done.

Second Phase: 3D Backbone Simulation

-Mainly focused on the 3D backbone simulation from two x-ray images that are taken from posteroanterior (P-A) and lateral view.

-The edge will be joined from the perpendicular to simulate the 3D bone. The technique involves including noise eliminating, blending, smoothing, and texture mapping.Third Phase: Spine Fixation

focused on the thoracic bone fixation. The thoracic vertebrae from T1 until T12 will be define their x, y, z coordinate accordingly at the middle of the vertebra.

-The x, y, z coordinate will be selected from the middle of the vertebrae.

-Before the operation, the Cobb angle will be calculated to ascertain the deformation of the thoracic spine. The most tilted upper and lower vertebra will be selected to calculate the Cobb angle using the Cobb Method.

-The surgeon will be asked to select the best location for placing the pedicle screws on the vertebrae. The hook will be installed base on the location that the surgeon has pre-selected.

Fourth Phase: User Interface Design

-The result can be used by the orthopedic surgeon to predict the best correction on the deformed spine thus to increase the reliability and obtain the best result of fixation. Please refer to http://fsktm.upm.edu.my/~cga2004/

Title : Surface Design of Total Knee Replacement Using Virtual Manufacturing
Project detail : IRPA-EA no: 04-02-04-0592-EA001
Amount : RM 156,360.00

Total Knee Replacement (TKR) is a surgical procedure involved in replacing deformed knee joints with artificial knee surfaces. Particularly, the artificial knee surfaces or material is called “prosthesis”. Mostly one part of the prosthesis is metal, and the medial part in between is a plastic material called polyethylene. TKR surgery is needed for various reasons, like one of these complications of arthritis, rheumatism, fractures of accident and so on. The purpose of surgery is to enable the patients suffering from severe joint pain, disabling and stiffness to return to active and rewarding lives. Nowadays, there are several methods using different materials and methods of implementing TKR. In general this study will propose a fully automated approximation system, which able to accurately measured the lost volume of the knee joint prosthesis, so that minimal changes of the surface can be detected. A variety of research has been done regarding this problem, but sometimes the researchers did not have any or enough information on the original design or blueprint of the knee joint. By approximating the original surface geometry of the Knee Prosthesis implant before wear and determining the differences, the volume of material lost can be calculated.

CAOS
Computer Aided Orthopaedic Surgery

The purpose Of The Computer Assisted Orthopedic Surgery Research group is to bring together those individuals throughout Malaysia, who, by their contributions and activities in the areas of research, clinical study, and use, technical activities have indicated or are indicating interest in computer assisted orthopedic surgery

The Research group aims to promote a new partnership between orthopedic surgeons and technologists as necessary basis for the successful integration of computer assisted surgical tools and techniques into the daily clinical routine.

CAOS will seek to accomplish these goals by holding a few related research and workshop and by disseminating information to it as an organization either at meeting or independently. By stimulating basic and clinical research, and by organizing postgraduate full time research the CAOS group hopefully can accomplish and assist the Universities in developing graduate and postgraduate teaching programs in this areas. The Group shall collaborate and co-operate with other associations and bodies whose efforts are directed at the same objective and whose interest are allied with or are similar to those of those of the Group itself.
