Bone Remodeling

Bone Remodeling

Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Virtual Work for a System of Connected Rigid Bodies

Virtual Work for a System of Connected Rigid Bodies

Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.
Next,...

Bone Structure

Bone Structure

Within the skeletal system, the structure of a bone, or osseous tissue, can be exemplified in a long bone, like the femur, where there are two types of osseous tissue: cortical and cancellous.

Frictional Forces on Screws

Frictional Forces on Screws

Screws are characterized by a helical ridge known as a thread wrapped around a cylindrical shaft. They are commonly used as fasteners to hold objects together or to transmit power and motion in machines. One type of screw that is particularly useful for transmitting power is the square-threaded screw.
A jack with a square-threaded screw is a mechanical device used to lift heavy loads by applying a force at its handle. When the force is applied, the screw turns, raising the load. The screw can...

Background:

Accurate simulation of bone machining is essential for effective surgical training.
Existing methods often lack precise force feedback, limiting realism.
Understanding bone material properties is key to simulating machining forces.

Purpose of the Study:

To develop a physics-based training simulator for bone machining.
To model the forces involved in bone material removal during milling.
To implement real-time haptic feedback for enhanced surgical simulation.

Main Methods:

Utilized a physics-based approach where the energy required to remove unit volume of bone is constant.
Modeled milling tool blades as small cutting elements to calculate interaction forces.
Employed a voxel representation for virtual bone and removed chips, incorporating material properties.
Integrated differential forces over engaged cutting elements to determine total machining force.

Main Results:

The physics-based force model accurately predicts forces during bone machining.
Experimental validation with real bone samples confirmed the model's efficacy.
A real-time haptic implementation was successfully developed for a dental training simulator.

Conclusions:

The developed physics-based simulator provides a realistic and accurate representation of bone machining.
The force model, based on material properties and voxel representation, is robust and experimentally validated.
