  2. Abstract • Man’s intrinsic desire to be active propelled the development of biomaterials. Hip joint replacement surgery is of the most revolutionary advances in modern orthopaedic surgery, which both relieves pain and improves function. The development of metallic biomaterials has emerged as the result of a process of evolution in a Darwinian manner. By the middle of the nineteenth century, physicians began performing systematic studies in order to better understand tissue-metal interaction. Unfortunately, the development of metallic biomaterials was limited by a lack of knowledge about durable and biocompatible materials. This historical review illustrates how surgeon-scientists who used off-the-shelf metallic biomaterials to treat their patients. The modern field of biomaterials science owes a great deal to these pioneering surgeons.

  4. Common Reasons for Hip Replacement Condition Incidence • osteoarthritis 60 percent • fracture-dislocations 11 percent • rheumatoid arthritis 7 percent • aseptic bone necrosis 7 percent • revision of previous hip operations 6 percent

  5. Bone replacement criteria include the following: • 1. Appropriate tissue-material interface • 2. Non-toxic • 3. Non-corrosive • 4. Adequate fatigue life • 5. Proper design • 6. Proper density • 7. Relatively inexpensive • 8. Elastic and mechanical properties comparable to those of bone

  19. Today, there are many new frontiers in biomaterials engineering, including: • 1. Porous Coatings • 2. Bioactive Ceramics • 3. Bulk Metallic Glasses • 4. Tissue Engineering

  20. Conclusions • The development of metallic biomaterials has emerged as the result of a process of evolution. • By the middle of the nineteenth century, physicians began performing systematic studies in order to better understand tissue-metal interaction. • Surgeon-scientists originally used off-the-shelf metallic biomaterials to treat their patients. • The modern field of biomaterials science owes a great deal to these pioneering surgeons.
