Prosthesis Application with Osteointegration

This is a surgical procedure that establishes a direct connection between bone and prosthesis. It is commonly used in post-amputation prosthetic applications and offers a more natural integration compared to traditional socket systems. Through osseointegration, the prosthesis is firmly attached to the body, providing greater comfort, functionality, and enhanced control for the user.

Core Principle of Osseointegration:

Osseointegration enables a biological interaction between bone and the prosthetic device. During the surgical procedure, the prosthesis is anchored directly into the bone using a metal rod or screw. Over time, bone cells attach to this metal structure and integrate it into the bone itself. This creates a stable and durable bond between the bone and the prosthesis. The process is typically performed using biocompatible materials such as titanium.

Benefits of Osseointegration in Prosthetic Applications:

Greater Comfort and Stability: Unlike traditional socket prostheses that are attached externally, osseointegrated prostheses are directly connected to the bone. This reduces friction and pressure, resulting in improved user comfort. It also allows for much more stable prosthetic movement.
Enhanced Sensory Feedback: Thanks to the direct connection between the prosthesis and the bone, the user can interact with the prosthesis in a more natural way. This improves balance and enables more precise control of movements.
Improved Mobility and Functionality: These prostheses offer better mobility, especially in activities that demand high performance, such as sports. In addition, unlike traditional sockets that may irritate the skin, osseointegration causes less discomfort and is more suitable for long-term use.
Long-Term Durability: Osseointegrated prostheses tend to be more durable over time, as the strong connection between the implant and the bone ensures long-lasting integration.

Osseointegration Procedure:

Surgical Intervention: Osseointegration is typically performed by a surgeon. A hole is drilled into the bone at the amputation site, and a biocompatible implant (usually made of titanium) is inserted. A waiting period is required for the implant to fully bond with the bone.

Healing Process: It usually takes about 3 to 6 months for the implant to fully integrate with the bone. During this time, temporary prosthetic devices may be used while the connection between bone and implant is solidifying.

Prosthesis Fitting and Adjustments: Once the implant is fully integrated into the bone, a custom-designed prosthetic limb is attached based on the user’s needs. The prosthesis connects to the implant, becoming fully functional.

Monitoring and Maintenance: Regular monitoring and follow-up care are essential after osseointegration. Doctors assess the stability of the bone–prosthesis connection and guide the patient through maintenance and long-term care.

Conclusion:

Osseointegration represents a revolutionary advancement in prosthetic applications. It can significantly enhance the quality of life for users by enabling more natural movement capabilities. However, this method may not be suitable for every patient, and the surgical and recovery processes must be carefully managed.
