parHipImplant

Below is a demonstration of the features of the parHipImplant function

Syntax

[F,V,C,curveSet]=parHipImplant(hipParStruct);

Description

This function creates a hip implant object based on an input structure containing control parameters. The hip implant does not current represent any particular implant geometry in use in clinical practise. Instead it is currently merely an excercise in the parameterisation of this type of objects and can be used to develop approximate models investigating him implant loading.

Examples

Plot settings

fontSize=20;
lineWidth=5;

%Define the parameter set
hipParStruct.ballRadius=20;
hipParStruct.stickRadius=7;
hipParStruct.stickLength=21;
hipParStruct.stickLengthStraight=hipParStruct.stickLength-6;
hipParStruct.neckRadius=15;
hipParStruct.neckEllipseScale=2;
hipParStruct.collarThickness=3;
hipParStruct.loftOffset=20;
hipParStruct.loftLenght=40;
hipParStruct.stemRadius=8;
hipParStruct.stemLength=50;
hipParStruct.stemAngle=0.25*pi;
hipParStruct.pointSpacing=3;

[F,V,C,curveSet]=parHipImplant(hipParStruct);
