| Summary: | Study of the wrist kinetics is important role in progressive of pathology and researches hope to develop new therapies for reduce the pains and restore the functional ability in the wrist joint. The aim of this study is investigating and comparing the peak contact pressure in radio-scaphoid articular joint with regard to finite element method & Rigid Body Spring Model method. With RBSM technique the structure of the wrist is represented in a model as a collection of rigid bodies, representing the bones, interconnected by compressive and tensile spring elements, representing cartilage and ligaments. This Method includes mathematical formula that calculated the stress & strain in regard to impact load in the Radio-Scaphoid joint. Results for joint model indicate that these two methods predict similar peak contact pressure on joint surface. But the RBSM is relatively simple and effective in predicting joint contact pressure under symmetric and non-symmetric loading. The computational efficiency of the RBSM method is particularly attractive for pre-operative planning of reconstructive surgical procedures in orthopedics. |
