Radial Head Partial Prosthesis

The commercial models that make up the Radial Head Partial Prosthesis family are classified as long-term implantable surgically invasive medical devices.
The Radial Head Partial Prosthesis is indicated for reconstruction of comminuted fractures and progressive radiocapitellar arthrosis in the human body. Its purpose is to restore or prevent the loss of elbow stability, range of motion and radial length.

The product was developed to withstand loads in both types of movement: flexion-extension and pronation-supination. Thus, it assists in bone reconstruction as well as in the transmission or relief of mechanical loads on the injured segments. The Radial Head Partial Prosthesis is a non-modular, single-component metallic radial component. Its end is chamfered to facilitate insertion into the medullary canal. The prosthesis head is highly polished to allow better joint performance.

This product is intended for partial arthroplasty of the joint, primary or revision, and was developed to be fixed to the radial medullary canal with bone cement.

Partial Radial Head Prosthesis is indicated in cases of comminuted fracture of the radial head associated with:

Elbow instability;
Rupture of the medial collateral ligament;
Ulnar lateral collateral ligament injury;
Equivalent Monteggia with fracture of the olecranon and radius;
Extensive coronoid fracture
Essex-Lopresti injury (injury to the radio-ulnar interosseous membrane and distal radio-ulnar joint).
The selection criteria for the size of the implant to be used will depend on the condition of the bone and the technique to be adopted to carry out the procedure. These conditions are the responsibility of the doctor who evaluates the patient and decides which implant should be used.
The implants were designed for use in the circumstances described above, so any other uses are considered contraindicated.
