Computer aided modelling of spastic hip joint based on CT date.
BACKGROUND
The main subject of the paper is development of three-dimensional numerical modelling method of children's hip joint. Anatomically correct as well as deformed due to cerebral palsy joints were taken into consideration.


METHODS
The modelling process was carried out on data obtained from X-ray computer tomography. Specialized software was used to develop three-dimensional models of particular objects (e.g. pelvis, thigh bone) of hip joint.


RESULTS
The CT-data of two patients from Clinic of Children Orthopaedics and Rehabilitation of Lublin Medical University was used to perform three - dimensional geometrical models of hip joints. Finite element models were prepared also taking into account inhomogeneity of the bone tissue.


CONCLUSIONS
RESULTS of our researches clearly show that three-dimensional, computer modelling of the children hip joint can be performed based on CT-data. Use of these methods will enable us to gain a better understanding of children hip joint deformation process and facilitate planning of therapy.
