Über dieses Buch

This book provides an in-depth review of state-of-the-art orthopaedic techniques and basic mechanical operations (drilling, boring, cutting, grinding/milling) involved in present day orthopaedic surgery. Casting a light on exploratory hybrid operations, as well as non-conventional techniques such as laser assisted operations, this book further extends the discussion to include physical aspects of the surgery in view of material (bone) and process parameters.

Featuring detailed discussion of the computational modeling of forces (mechanical and thermal) involved in surgical procedures for the planning and optimization of the process/procedure and system development, this book lays the foundations for efforts towards the future development of improved orthopaedic surgery.

With topics including the role of bone machining during surgical operations; the physical properties of the bone which influence the response to any machining operation, and robotic automation, this book will be a valuable and comprehensive literature source for years to come.



Chapter 1. Introduction

Orthopedic surgery is the operational procedure employed for dealing with problems associated with bones, joints. Orthopedic surgeries are becoming important part of the human life. As a result of advances in medical field, the number of people seeking orthopedic treatments has been increasing. Some of the major contributors towards increasing number of orthopedic surgeries are old age, injuries related to sports, and military. The field of orthopedics has become very important in day to day life.

Chapter 2. Fundamental Operations of Bone Machining

Currently, the majority of conventional orthopedic surgeries adopted for shaping and forming bones involve the contact methods based on controlled mechanical fracturing (chipping) of the bones.

Chapter 3. Non-conventional and Hybrid Methods of Bone Machining

Having explored the basics of important fundamental contact (mechanical) and non-contact (thermal) operations involved in machining of the bones, the discussion will proceed towards some of the non-conventional techniques.

Chapter 4. Attributes of Bone Machining

Any machining operation has certain key attributes depending upon the material undergoing the process, the type of process, and choice of process parameters. In case of bones and hard tissues, which are composite materials, these attributes very much characterize the uniqueness of their machining operations. Having discussed the basics about state of the art of orthopedic surgery, nature of bones, and fundamentals of various machining processes (conventional and non conventional ), the current chapter takes the discussion ahead with attributes of machining process.

Chapter 5. Temperature Evolution During Bone Machining

The heat evolved during any machining operation as a secondary effect (in mechanical machining) and/or primary or inherent effect/source (in beam based machining) results in temperature increase of the bone.
Narendra B. Dahotre, Sameehan S. Joshi

Chapter 6. Computational Modeling in Bone Machining

In general machining of materials is a complex process involving several process and material parameters. During machining, multiple physical phenomena are associated with combination of these process and material parameters. These physical phenomenon may occur simultaneously or in sequence rendering the process of machining very complex.
Narendra B. Dahotre, Sameehan S. Joshi

Chapter 7. Potential Automation of Bone Machining

The ultimate aim of research related to surgery is to reduce human dependency during operational procedures. The current chapter focuses on such automation efforts undertaken in the field of bone machining. State of the art in the field has been presented. The need for such efforts arises from the fact that involvement of human being in the surgery as an operator requires a lot of experience to develop the precise skills and it always involves a risk of human error. Another important aspect is the constraint on geometry which can be machined in manual operation. With this background, the efforts related to automation and robotics in the field of bone machining are described.
