Orthopedic Implants: Metal Types, Varieties and Usabilities

What are Orthopedic Implants?

Orthopedic Implants belong to one of the most important medical device categories and orthopedic implants manufacturers own enormous standing in the large production line. These are the imperative tools and devices that are used in treating the broken bones, missing joints, bone deformation and injuries due to severe accidents, the decay of bone and other bone-related concerns. More precisely speaking, an orthopedic implant is restorative medical equipment fabricated to supersede an absent joint or bone or to support a cracked bone.

Since these medical tools and devices are playing an invaluable role in the fixation process and the selection of the implant material is very matter of high consideration as the material impacts tissue receptivity, stiffness, biocompatibility and corrosion. This implant is specially manufactured using stainless steel and titanium metals for persistence and it has the polymerised coated layered that serves as assistant cartilage. GWS orthopedic implant company requires special attention in the substance material while manufacturing these implants as their exterior morphology impacts its resistance within the bone or the around cement mantle.

General Information on Important Metal Types

While talking about the material quality of orthopedic implants, the ideal material must have high fatigue resistance, good wear resistance, low elastic modulus, and great strength. The important characteristic of ideal material should be chemically inert, completely corrosion-proof and entirely biocompatible. Although ceramics and polymers are also used as conventional material for manufacturing orthopedic implants, prominent manufacturers mainly prefer metal type substances. They are-

Stainless steel orthopedic implants: Surgical grade stainless steel is usually used for making non-permanent implants like internal fixation devices. Due to lower fatigue strength, stainless steel may not withstand plastic deformation.

Titanium orthopedic implants: Immaculate commercial titanium and titanium alloys are extremely biocompatible and more corrosion resistant. It has titanium oxide on the surface which makes it penetrable instead of breakable. Abrasion of this layer often causes particle discharge into the neighboring tissues. But since the metal is biocompatible, the released particles suitably respond with tissue ensuring long-term aseptic unfastening of the implant. The titanium is normally used for the manufacturing of permanent implants.

Another metal variety of Orthopedic Implants is cobalt-based alloys that were used as a permanent metal alternative before Titanium came into practice. This metal is also corrosion resistant and its surface has the layer chromium oxide which makes it very durable. The only drawback is ion release in vivo and this may cause cancer in the living tissue. This is the main reason; Titanium replaced its use and became the ideal metal for permanent orthopedic trauma implants.

Different Categories of Orthopedic Implants and Their Usability

For patients, going through an orthopedic implant surgery is nothing less than a thriller experience. It contributes the most high-grade operational result for inmates looking to overcome joint ache and reclaim mobility. There are principally three varieties of orthopedic implants-

Screws: Screws can be both horizontal and Phillips's head. They are utilized to bind up broken areas, like split labrum or rotator wrist. They are also practiced to restore fractured bone or revive resistance in a vulnerable area.

Plates: Orthopedic trauma implants plates come in 5 primary types-

Buttress plates (used to sustain bone breakages especially at the end of lengthy bones particularly at the joint knee and ankle), Neutralization plates (a kind of plates that serve to ford the fractured zone, adjusting the pressure so that screws can tighten and sustain the area), Bridging plates (used to secure the area while fitting height and order), Tension plates (wires applied to tighten an area as it recovers) and Compression plates (alloy plates utilized to restore a bone by exerting forceful pressure between bone parts to encourage healing)

Prostheses: Orthopedists implement a variety of orthopedic prosthetic implants to reconstruct missing joints or bones or to provide support to a weakened or cracked bone.

Some of the Most Important Examples of Orthopedic Implants

  • ACL-PCL Implants:

These Implants are generally used during Arthroscopy surgical procedure. Some of the important implants under this category are- ACL Screw Cannulated (Interference Screw), ACL(Endo) Button, Anchor Screw, Eight Plate, Endobutton with Loop, Fixation Screw, Low Profile Cancellous Screw, Spiked Ligament Staple, Spiked Ligament Washer, Suture Washer D-Hole, Suture Washer Round Hole and Wedge Osteotomy Plate.

  • Cannulated Cancellous Screw:

The characterized shape of Cannulated screws has a round centre shaft and the cancellous screws are utilized for metaphyseal breakages. The principal benefit of cannulated screws is that they can be implanted above a guidewire or lead pin. The width of the lead pin is more diminutive than the cannulated screw so that it can certainly be interpolated with the help of fluoroscopy in the surgery room. Since the pin has a smaller diameter, it is eligible for reinsertion for several times to secure proper placement without extreme injury to the bone. One exceptional variety of cannulated cancellous screw is the Knowles pin that is practiced for fixation of slipped capital femoral epiphysis in kids.

  • External Fixation Device:

When it comes to fixing fractured bones, external fixation devices play a significant role. This fixation device supports the fractured bone to stay aligned. The device can be fitted externally to hold the bone in an optimal state throughout the restoration process. This equipment is usually applied to kids and when the skin over the wound gets infected. Double Adjustable Clamp is an important type of External Fixators.

  • Hip Prosthesis:

Hip Prosthesis is used during Hip replacement surgery where a surgeon operates and shifts a displeasing hip joint with osteoarthritis and replenishes it with a feigned joint like Austin Moore Narrow Stem. It normally is performed when all other therapy choices fail to give sufficient pain relief. Implantation of Hip Prosthesis relieves a disturbing hip joint and lets one walk effortlessly.

  • Intramedullary Nail:

The intramedullary nail is used to mend a fractured bone and retain it still and stable. The nailing surgery is mostly performed on the bones of the upper arm, shin, hip and thigh. During this particular bone operation, a permanent nail or rod is installed into the middle of the bone so that the patient can put weight on the bone while walking or making movements.

  • Large Fragment:

Large Fragments are important orthopedic implants that are used in order to treat bicortical fixation in diaphyseal bone using condensation plating with standard cortex pins. The 4.5mm Cobra Head Plate is a significant model of this type of fragments and it has a conical head that helps in the alignment of the locking bolt in the stringed base space to give an implanted bond between the nail and the plate.

  • Locking Plates:

These special surgical tools are employed to support fractures. They differ from conventional plates in terms of pinheads bar. This plate offers a composite section or framed-edge device. Conventional plates are tightened on the underlying bone by the weight stamped fitting regular screws. Locking plates serve as fixed-angle support to keep alignment while presenting enhanced balance. This type of erection further avoids the dependent wreck of comminuted metaphysical displacements. Some important variants are- Variable Angled (Double Column), Locking Buttress Plate, Dorsal L-Oblique Plate, Radius Dorsal Plate, Radius Dorsal T-Plate, Clavicle Superior Anterior Distal Locking Plate Left & Right, Reconstruction Plate, Distal Femur Plate etc.

  • Maxillofacial Implants:

These implants play a vital role in overall recovery by repairing physical and emotional well-being in sufferers with abstaining or damaged facial structures due to intrinsic deformities, injury, or disorder. These surgical tools and devices are used in the diagnosis and operation of an all-inclusive variety of disorders concerning the facial complex and skeleton, including the facial bones and teeth. Chin Plate is one of the important maxillofacial implants that are designed for the treatment of Mandible Reconstruction, Intermaxillary Fixation, oral and maxillofacial surgery, Mandible Trauma, Orthognathic Surgery etc.

  • Radial Implants:

Radial Implants are generally practised in the surgery of spiral head wounds or sequela. Most common cases that require the application of these implants are- Failure to replace exact anatomy, critical elbow traumatic weakness and collapse of osteosynthesis hardware etc. Few examples of this type of implants are- Locking Proximal Radius Plate for Radial Head Rim, Titanium Radial Head Prosthesis etc. The Instrument Set for Radial Head Prosthesis is also available and the set includes- Impactor for Radial Head, Straight AWL (3.0mm, 4.0mm, 5.0mm), Radial Neck Planner, Slotted Hammer, Radial Head Measuring Gauge, 7 Rasp (for 5mm/ 16mm/ 17mm/ 18mm/ 19mm/ 20mm/ 21mm/ 22mm/ 23mm), and 9 pieces of Trial head (15mm/ 16mm/ 17mm/ 18mm/ 19mm/ 20mm/ 21mm/ 22mm/ 23mm).

  • Small Fragment and Mini Fragment:

Small Fragment is vertical plates with round or elliptical slots that are designed for little bone fixation on both sides of the fracture. Some of the special models of this implant are- Small Dynamic Compression Plate, Cervical Spine H Plate, One Third Tubular Plate and Y Reconstruction Plate. On the other hand, Mini Fragment Implants are intended for treating humble bone likes fingers, wrist, and bow and ankle bones. This Fragment System is used for fixation of bone ruptures, Osteotomy, re-plantations, and mergings of tiny bones and humble bone pieces.

  • Spinal Implants:

This particular range of implants is used during a surgical operation to treat deformation, support and strengthen the spine, and improve coalition. Spinal implants play a significant role in treating many forms of back injury and disfigurement. Its principal purpose is to weld two vertebrae together and reinstate implanted plate material. The medical concerns treated with the help of these implants are spondylolisthesis, scoliosis, degenerative disc disease, kyphosis, and fracture.

  • Orthopaedic Sets:

To fix the implants properly, surgeons need special tools and devices. Orthopedic sets are the collection of those essential tools and devices that are needed for orthopedic surgical operations. GWS LLP Surgicals, India's of the best orthopedic implants manufacturers and suppliers, has an all-inclusive stock of these sets and some of the best varieties are- ACL-PCL Instrument Set, DHS-DCS Instrument Set, Femur Interlocking Nail Implant Set, Tibia Interlocking Nail Implant Set, Spinal Implant & Instrument Set, Mini Fragment Implant & Instrument Set, PFN-II Implant Set, Laminectomy Instrument Set and Locking Large Fragment Implant & Instrument Set.
