Orthopaedic Implants in Rajasthan
An orthopaedic implant is a specially designed medical device made of biocompatible materials (such as stainless steel, titanium alloys, or cobalt-chromium) that is surgically placed inside the human body to replace, support, or stabilize bones and joints. These implants are used in the treatment of fractures, bone deformities, joint replacements, and spinal conditions.
Examples: Bone plates, screws, intramedullary nails, joint prostheses (hip, knee, shoulder), spinal rods, and cages.
Purpose: To restore mobility, provide structural stability, relieve pain, and promote proper healing of bones and joints.
Common Orthopaedic Implants:- These implants are essential in restoring bone integrity, supporting structural alignment, and enabling joint function.
1. Plates & Screws:
- Orthopaedic plates: Metal implants used for internal fixation of fractures, working alongside screws to stabilize bone fragments.
- Bone screws: Available in types like cortical and cancellous screws, used for securing plates and stabilizing fractures.
2. Intramedullary (IM) Nails/Rods:
- IM nails (also known as interlocking or Kuntscher nails) are rods inserted into the bone's medullary canal to stabilize long-bone fractures, enabling load-sharing and early mobilization.
- Variants include PFN (proximal femoral nail), tibial nails, humeral nails, and elastic or reconstruction nails.
3. Prostheses (Joint Replacements)
- These include hip (e.g., Austin-Moore, Charnley), knee (e.g., Insall–Burstein), shoulder (Neer), and elbow (Baksi) prostheses that replace joint surfaces to restore function and relieve pain.
4. Pins, Wires, Staple Systems
- Kirschner wires (K-wires): Thin wires for temporary fixation of small bone fragments.
- Steinmann pins, Schanz screws, staples, and cerclage wires: Used in skeletal traction, external fixation, and fracture alignment.
5. Spinal & Other Specialized Implants
- Spinal implants include pedicle screw systems, rods, cages (e.g., ACIF, PLIF, TLIF), cervical plates, and titanium mesh used in spinal stabilization and fusion.
- External fixators: Frame systems used to stabilize fractures externally, also visible in some of the images.
|
Biocompatibility |
Made from materials (like stainless steel, titanium, cobalt-chromium alloys, or PEEK) that do not trigger harmful immune responses in the body. |
|
High Strength & Durability |
Designed to withstand mechanical loads, body weight, and stress during movement and healing. |
|
Corrosion Resistance |
Resistant to rusting and degradation from body fluids, ensuring long-term safety inside the body. |
|
Variety of Types & Designs |
Includes plates, screws, rods, nails, prostheses, wires, and external fixators for different bones and surgical needs. |
|
Precision Engineering |
Manufactured with exact dimensions and tolerances to fit bone structures accurately and allow secure fixation. |
|
Compatibility with Instruments |
Designed to work with standard orthopaedic instruments (drills, screwdrivers, taps, plate benders) for easy surgical handling. |
|
Different Sizes & Configurations |
Available in multiple shapes and sizes to match different bones (femur, tibia, humerus, spine, etc.) and patient needs (adult, paediatric). |
|
Surface Finishing & Coating |
May have polished, roughened, or coated surfaces (e.g., hydroxyapatite, porous coating) to promote bone growth and better fixation. |
|
Load Sharing & Stability
|
Designed to stabilize fractures and sometimes share the load with the bone to encourage natural healing.
|
|
Sterilizable |
Manufactured to withstand repeated sterilization processes without losing strength or function. |
|
Temporary or Permanent Use |
Some implants (like fracture fixation plates and screws) may be removed after healing, while others (like joint prostheses) are designed to remain permanently. |
|
Radiolucency (in some materials)
|
Certain implants (like carbon fiber or PEEK-based devices) allow X-rays to pass through, making post-operative imaging easier. |
