Flex Finger System

Dual-Function Flexible Implant Design

The implant serves as both a dynamic spacer and an internal scaffold : it maintains the alignment and spacing of the reconstructed joint; Provides structural support for the naturally formed capsuloligamentous system; achieves biomechanical reconstruction, offering advantages over traditional simple resection arthroplasty.

Bone Remodeling Advantages

The non-fixed design allows compressive loads to be evenly distributed across the bone resection surface and cortical diaphysis, avoiding stress concentration. It helps maintain the original bone length, preserves the natural morphology of the osteotomized end, promotes cortical thickening, supports new bone formation around the implant, and contributes to long-term bone health maintenance.

Excellent Stability Mechanism

Without the need for traditional permanent fixation devices, the implant achieves stability through encapsulation by surrounding soft tissue. The stem of the implant allows for micro-motion, enabling more even load distribution. The flexible hinge can dynamically adjust to the optimal mechanical axis of rotation, improving joint movement coordination.

Press-Fit Washer Protection System

Utilizes a non-attached, press-fit titanium washer to precisely protect the middle section of the implant; Significantly reduces the risk of wear, abrasion, and

cutting of the implant by bone tissue; Avoids stress concentration caused by rigid fixation, improving biomechanical compatibility at the implant-bone interface.
