Jindal Medi Surge's [JMS] Orthopedic Radial Head System is a medical device used in orthopedic surgery to treat injuries and conditions related to the radial head, which is the disc-shaped bone at the elbow joint that articulates with the humerus and ulna. Injuries to the radial head can result from trauma, such as falls or accidents, and can range from simple fractures to more complex fractures and dislocations. The Orthopedic Radial Head System is designed to replace or repair the damaged radial head. There are various types of implants and systems available, and the choice depends on the severity of the injury, the surgeon's preference, and the patient's individual needs. Some common components and techniques associated with this system include: Radial Head Prostheses: These are artificial implants designed to replace the damaged or fractured radial head. They are made from various materials, including metal and polyethylene, and come in different shapes and sizes to match the patient's anatomy. Radial Head Repair: In some cases, instead of replacing the radial head, surgeons may opt for repair techniques like open reduction and internal fixation (ORIF) using screws and plates to stabilize the fractured bone. Arthroplasty: This is a surgical procedure that involves the replacement of the radial head with a prosthetic implant, which can be part of the Orthopedic Radial Head System. Rehabilitation: Following surgery, rehabilitation is crucial to restore range of motion and function to the elbow joint. Physical therapy and exercises are often recommended to aid in the recovery process. The choice of treatment depends on factors such as the type and severity of the injury, the patient's age and activity level, and the surgeon's expertise. The goal of using the Orthopedic Radial Head System is to restore the stability and function of the elbow joint, reduce pain, and improve the patient's quality of life.

🦴 Orthopedic Radial Head Implants – Detailed Overview

Radial head implants (also called radial head prostheses) are orthopedic devices designed to replace the damaged radial head portion of the radius bone at the elbow joint. They are commonly used in complex radial head fractures that cannot be reconstructed with plates or screws.

🔹 1. Indications for Radial Head Implants

Radial head replacement is typically indicated when:

• Comminuted (multi-fragmentary) radial head fractures

• Unstable elbow injuries

• Fracture-dislocations of the elbow

• Associated ligament injuries

• Failed fixation or non-union of radial head fractures

🔹 2. Types of Radial Head Implants

🔸 Monoblock (Monopolar) Radial Head Prosthesis

• Head and stem are a single piece

• Simple design

• Good primary stability

🔸 Modular Radial Head Prosthesis

• Separate head and stem components

• Allows intraoperative size customization

• More anatomical reconstruction

🔹 3. Fixation Methods

🔹 Cemented

• Implant stem fixed using bone cement

• Preferred in poor bone quality

🔹 Cementless (Press-Fit)

• Stem achieves fixation by tight fit

• Allows bone ingrowth over time

🔹 4. Implant Components

• Radial Head (articulating surface)

• Stem (inserted into radial canal)

• Optional Spacer / Collar (in modular systems)

🔹 5. Materials Used

• Cobalt Chromium Alloy – high wear resistance

• Titanium Alloy – lightweight, excellent biocompatibility

• Stainless Steel (SS316L) – strong and economical

All materials are corrosion resistant and biocompatible.

🔹 6. Sizes & Dimensions (Typical)

• Head Diameters: 18 mm – 28 mm

• Head Thickness: 6 mm – 14 mm

• Stem Diameters: 6 mm – 10 mm

• Stem Lengths: Short / Standard / Long

(Exact sizes vary by manufacturer and system.)

🔹 7. Design Features

• Anatomical head contour

• Smooth polished articulating surface

• Optional collared stems

• Multiple head diameter and height options

• Modular assembly for precise reconstruction

🔹 8. Clinical Benefits

• Restores elbow stability

• Maintains forearm length

• Reduces pain

• Enables early mobilization

• Improves range of motion

🔹 9. Surgical Applications

• Complex radial head fractures

• Elbow fracture-dislocations

• Post-traumatic arthritis (select cases)

• Revision of failed radial head fixation

🔹 10. Sterilization & Packaging

• Supplied sterile or non-sterile

• Compatible with steam and EO sterilization

📌 Summary

Orthopedic Radial Head Implants are essential solutions for treating irreparable radial head fractures. Available in monoblock or modular designs and manufactured from high-quality biocompatible metals, these implants help restore elbow stability, alignment, and functional movement.
