A groundbreaking new external fixator developed by the orthopedic team led by Dr. TARNG Yih-Wen, Vice President of Kaohsiung Veterans General Hospital, has successfully addressed long-standing challenges in bone fracture treatment. This novel flat-profile external fixator not only reduces the size of traditional external fixators by 80%, but also provides more effective fixation for fractures, significantly improving patient quality of life and shortening treatment times.

Chronic osteomyelitis and infectious nonunion are persistent issues in orthopedic practice, with conventional treatments often requiring long-term use of large, bulky external fixators. These can cause significant inconvenience to patients and may lead to complications such as joint stiffness.

Innovative Design Breaks Traditional Limits

Traditional external fixators typically consist of multiple pins inserted into the bone, connected by crossbars that form a three-dimensional frame to stabilize the fracture. In contrast, the flat-profile external fixator introduces several key design innovations:

Pin Configuration: The pins are more tightly arranged and placed closer to the skin, providing a more stable fixation.

Crossbar Design: The crossbars are flatter and arranged horizontally, rather than vertically as in traditional models, making the external fixator better fit the body’s contours and reducing pressure on soft tissues.

Connection Mechanism: Instead of traditional screw tightening, the pins and crossbars are locked together using threaded connections, offering stronger fixation and minimizing the risk of loosening.

Joint Modules: Special joint modules are incorporated to better match the shape of the joints, reducing joint restrictions and ensuring more stable fixation.

In addition to these innovations, the flat-profile external fixator offers several advantages over traditional models:

Compact and Lightweight: At only one-fifth the size of conventional fixators, this device greatly enhances patient mobility, allowing them to engage in daily activities.

Superior Fixation: The unique design provides a more stable fixation, effectively promoting bone healing.

Reduced Risk of Joint Stiffness: By avoiding fixation across joints, the device reduces the risk of joint stiffness.

Lower Infection Risk: Fewer surgical interventions reduce the risk of infection and shorten the overall treatment duration.

Proven Clinical Efficacy

Clinical trials have confirmed that the flat-profile external fixator effectively shortens treatment times, reduces the risk of infection, and enhances patients' quality of life. Furthermore, the technology has been granted a patent in Taiwan and has successfully been transferred for commercialization, with widespread use in clinical practice.
