Orthopedic Implants

Orthopedic prosthetic implants give support to the bones by replacing missing or broken joints or bones. Orthopedists commonly use hip and knee prostheses which allow the patient to regain the motion completely without any pain. In few instances, the prosthetic element can be coupled with a healthy bone to mend a diseased or broken bone, or prostheses can substitute several parts of a joint bone undividedly.

Ideal Orthopedic Implant Material

An ideal orthopedic implant material should be

• Chemically inert
• Biocompatible
• Great strength
• High fatigue resistance
• Low elasticity
• Corrosion-proof
• Good wear resistance
• Inexpensive

Material type

Orthopedic prostheses implants manufactured mainly are of three types

• Metals
• Polymers
• Ceramic

Metal-based

Metals employed in orthopedic implants involve surgical grade stainless steel usually 316L, cobalt–chromium alloys, and pure commercial titanium (Ti) or titanium alloys. Stainless steel is utilized for temporary implants, such as inner fixation materials, because of its lower fatigue durability and the possibility to feel plastic deformation. Before the use of titanium, cobalt-based alloys had chiefly displaced stainless steel as materials for permanent implants. These alloys are usually more corrosion resistant, owing to the development of a durable chromium oxide surface layer. Despite the good corrosion resistance, ion release in vivo is a significant matter, as chromium, nickel, and cobalt are recognized carcinogens. Titanium implants are the material currently used because they are highly biocompatible, corrosion-resistant in comparison to Co-Cr alloys.

Polymers

The commonly handled polymer, in orthopedics, is ultra-high-molecular-weight polyethylene (UHMWP) or high–density polyethylene (HDP). Consequently, polyethylene is the best material for joining with metal or ceramic.

Despite the growing implantation of cement-less devices, the use of bone cement, which is an acrylic polymer, remains popular. New cementing techniques are accountable for the much enhanced clinical outcome of cemented prosthetic implants. It should nevertheless be stressed that cement does not act as a glue, but solely as a filler that allows mechanical anchoring of the implant and transfer of load from the prosthesis to the bone.

Ceramics

The ceramics applied in orthopedic implants include aluminum oxide and calcium phosphates. These ceramic elements are very immune to compression but vulnerable under tension and shear.

Calcium phosphate ceramics are especially engaging as implant coatings because of their extraordinary biocompatibility and reactivity. Titanium and titanium alloys are covered with hydroxyapatite (HA) using various means. These calcium phosphate implant layers have demonstrated strong advanced porous implant fixation and immediate bone ingrowth.

Solutions to improve the Orthopedic fixation

One of the solutions can be research to develop the materials in cemented artificial hips and thereby enhance their durability. The latest cement tweaks, the way the cement is blended and additives, are all being examined. As the method by which the cement breaks down is not thoroughly conceded, it is expected that research will be able to cast awareness on the process and support for secondary differences in the current cement to resolve the difficulties. Since cemented prostheses enable quick recovery moments and a more powerful primary link, if the endurance of the cement could be advanced, such a process would have many benefits. Yet, clinical trials of new components or methods will have to wait several years before the full consequence of this solution can be perceived.

Bone Cement plays an important role in the efficient usage of orthopedic implant prostheses in hip and knee joints.
