Method:A subject living with below-knee prosthetic socket for 5 years was recruited,and the original data of the stump was obtained through 3-D measuring and MRI.

This paper expounds particularly the selections of amputative sectio ns,the innovations of the modern amp utative technologies,the particul ar of children amputation,the oper-ational particular of thigh amputation,and the rehabilitation of the non-ideal stumps impairing.

Objective: To provide a scientific basis for prosthetic socket design,and to find the biomechanical interaction between the residual limb and prosthetic socket,the idea of reconstructing the residual limb and prosthetic socket and performing mechanical analysis was proposed.

This paper developed a three dimension finite element model to analyze stress distribution on residual limb of crus under lumped loads with different displacement constraint conditions.

Taking a transtibial residual limb as object,three dimensional finite element(FE) models of the residual limb and prosthetic socket were constructed.
