Implant Technology; Efficient Method for Orthopedic Surgery

Orthopedic implants are widely used nowadays in bone repair surgeries, with plans underway to develop more durable materials to make such implants.

Orthopedists use implants a lot in their surgeries. All artificial joints are implants. All metal parts inserted inside or put on the surface of cracked or broken bones in surgeries as well as parts used to keep broken pieces of bones together are all implants.

Implants are used widely in orthopedics. They are made of materials which do not trigger any reaction from, and are not rejected by the human body. Steel, titanium, plastic and biomaterials such as hydroxyapatite can be used to make implants.

Orthopedic implants are used in the form of screws, rods and metal sheets in order to keep broken bones in the right position to expedite recovery. An operation is usually needed to put implants in place, and another surgery is required to remove them.

Orthopedic implants can be studied and evaluated from four perspectives: physical, chemical, structural and biological. In the evaluation process, parameters such as the appearance, weight, magnetic properties, material used in the production, the way of production, and environmental friendliness of implants are examined.With regards to orthopedic implants, the objective sought today is to develop and use materials that are stronger, more durable and more compatible with the body. At the moment, orthopedic implants are used in a variety of areas. Currently, most pieces of orthopedic equipment are made of stainless steel and titanium alloys, which are durable enough and can be attached to plastic that can be used as false cartilage.

Bone repair operations may take several hours, and, depending on the kind of cracks, local or general anesthesia may be required. Given the type of the crack, the surgeon makes the appropriate incision and uses orthopedic implants, temporarily or permanently, to fix and treat the bone.

Recently, considerable progress has been made in the field of orthopedic implants, making their use simpler and more efficient.
