Chapter Summary

The book is a single-author treatment of biocompatibility, defined broadly as the biological performance of materials used in medical devices. After a short introductory part, it is organised in three sections: how materials respond to the body, how the body responds to implants, and how both are tested. Two short "Interparts" summarise implant materials and their clinical performance, and a glossary closes the volume.

General Considerations: Biocompatibility and the Biological Environment

The opening part contains two chapters: "Biocompatibility: Definitions and Issues" (consensus definitions, the discipline of biomaterials, and an afterword on a paradigm shift) and "Introduction to the Biological Environment" (a comparison of external and internal conditions, the elements of the biological environment, the life history of an implant and preimplantation handling effects). Together they set the vocabulary and frame the rest of the book.

Material Response: Function and Degradation of Materials In Vivo

This section looks at what the body does to the material. "Swelling and Leaching" covers diffusion, absorption, osmotic equilibrium and planned leaching such as drug release. "Corrosion and Dissolution" is the longest treatment: the chemistry of corrosion, Pourbaix diagrams, the electrochemical series, corrosion rate, forms of corrosion, corrosion in implant applications and the dissolution of ceramics and polymers. "Reactions of Biological Molecules with Biomaterial Surfaces" addresses denaturation, interfacial adhesion and charged interfaces. "Mechanics of Materials: Deformation and Failure" and "Friction and Wear" bring in elastic modulus, yield and fracture strength, friction, lubrication and wear.

Interpart 1: Implant Materials: Properties

A reference chapter that surveys the properties of metals, polymers, ceramics and composites used for implants, to be consulted alongside the material-response chapters.

Host Response: Biological Effects of Implants

The largest section turns to what the implant does to the body. It begins with "The Inflammatory Process" (the inflammatory response, infection and the effects of implant degradation products) and "Coagulation and Hemolysis" (the coagulation cascade and approaches to thromboresistant materials). "Adaptation" and "In Vitro Tissue Growth and Replantation" cover tissue growth strategies and a critical look at tissue engineering, including the cell-receptor paradigm, matrices and cell sources. "Allergic Foreign Body Response" deals with immune mechanisms and hypersensitivity reactions associated with implants, and "Chemical and Foreign-Body Carcinogenesis" with the evidence for implant carcinogenesis in humans.

The section then follows degradation products through the body: "Mineral Metabolism" (iron and chromium metabolism, dietary metal intake), "Systemic Distribution and Excretion" (movement of solid bodies and transport of dissolved species) and "Effects of Degradation Products on Remote Organ Function". "Interpart 2: Implant Materials: Clinical Performance" uses total hip replacement as its worked example.

Methods of Testing for Biological Performance

The final section covers how biological performance is established. "In Vitro Test Methods" (test strategies, tissue-culture and blood-contact tests), "In Vivo Implant Models" and "Clinical Testing of Implant Materials" (the goal and design of clinical trials and the decision for general clinical use) move from the laboratory to the patient. "Standardization and Regulation of Implant Materials" gives the historical perspective and the U.S. federal regulation of devices, and "Design and Selection of Implant Materials" discusses the design process. The last chapter, "Clinical Performance of Biomaterials", treats device retrieval and analysis, a proposed national implant retrieval programme and autopsy retrieval studies, followed by a glossary.

Key Concepts

General Considerations

• Biocompatibility as biological performance: the opening chapter works through consensus definitions and treats biocompatibility in terms of how a material performs in the biological environment.
• Implant life history: the sequence from handling before implantation through residence in the body, which determines what the material meets.

Material Response

• Swelling and leaching: uptake of fluid and loss of components governed by diffusion.
• Corrosion and dissolution: electrochemical degradation of metals, together with the dissolution of ceramics and polymers.
• Deformation, friction and wear: mechanical behaviour of materials in service.

Host Response

• Inflammation and foreign-body response: the body's reaction to an implant and to its degradation products.
• Coagulation and hemolysis: blood-material interactions and thromboresistant materials.
• Systemic effects: distribution, excretion and remote-organ effects of released species, including carcinogenesis and hypersensitivity.

Testing and Regulation

• In vitro, in vivo and clinical testing: the three levels at which biological performance is evaluated.
• Standardization and regulation: how consensus standards and federal regulation shape implant materials.
• Device retrieval and analysis: studying explanted devices to learn about clinical performance.

Critical Analysis

Strengths

• A deliberate two-sided structure. The publisher's description presents material response and host response as parallel sections, so a reader sees degradation of the implant and the body's reaction as one interaction.
• Fundamental level of treatment. The publisher states that the book concentrates on principles of biological performance at a relatively fundamental level, drawing on the author's decades of teaching, research and consultancy. The corrosion chapter, for example, builds from the chemistry of corrosion and Pourbaix diagrams to implant-specific factors.
• Coverage from bench to clinic. Testing is treated in three stages (in vitro, in vivo, clinical), followed by standardization, regulation and device retrieval, which suits readers preparing for device-industry work.
• Practical summaries. The two Interparts summarise the physical properties of commonly used metallic, polymeric and ceramic biomaterials and use a clinical case (total hip replacement) to connect the principles to implant performance.

Limitations

• A single reference-style volume from the mid-2000s. The fourth edition dates from 2005–2006, so it does not cover later developments in the field; it should be paired with a current source on regulation and tissue engineering.
• Materials are not the main subject. Material families are summarised in the Interparts rather than taught in depth, so readers without a prior materials course will need a separate introduction to polymers, metals and ceramics.
• Reference-style organisation. Chapters are short topical treatments grouped into sections rather than a single teaching sequence, so the book suits reading and reference more than a semester-long course built around it.

Where It Fits in the Course

Within the biomaterials course, this book is a specialist companion to the broader texts. Biomaterials: A Basic Introduction and Biomaterials: The Intersection of Biology and Materials Science are introductory textbooks that teach the field from the ground up, and Introduction to Biomaterials: Basic Theory with Engineering Applications is a concise course text; each of these is the better first book. Biomaterials Science: An Introduction to Materials in Medicine is the large multi-author reference that surveys material classes, applications and tissue engineering across hundreds of pages.

Black's volume sits after those. It is the book to take down when the question is why an implant degrades, what the body does in response, and how that is tested and regulated. Its focus on biological performance complements, rather than replaces, the material-class and application coverage of the multi-author handbook.

How to Use This Book

The book suits graduate students and advanced undergraduates who already know basic materials science and some biology, and engineers or regulatory staff who need the mechanisms behind biocompatibility. It is not a first introduction to biomaterials.

A practical plan for a course or self-study:

• Core: the two chapters of the opening part, then the Corrosion and Dissolution, Inflammatory Process, and Coagulation and Hemolysis chapters, which carry the central argument about degradation and host response.
• Read selectively: the mechanics chapters (Mechanics of Materials; Friction and Wear) if a mechanics course has covered the material; the carcinogenesis, mineral metabolism and systemic distribution chapters for toxicology-oriented work.
• For design and industry use: the testing section, Standardization and Regulation of Implant Materials, and Design and Selection of Implant Materials, read with a current regulatory source.
• Reference use: Interpart 1 for implant material properties and the glossary for terminology.

Pair each section with a concrete case: a specific implant, its likely failure mode and the test that would detect it.
