Evans osteotomy wedge is used to correct flatfoot deformities, fractures or osteotomies in the foot, and it ensure bone fixation. The porous structure of these wedges enhances osseointegration. According to scientific research, the porosity type of these implants has a maximum surface-to-volume ratio, which facilitates internal bone growth. These implants are made using 3D printing with titanium material.
Some features of the Evans wedge prosthesis are as follows:
- Presence of TPMS porous structure to improve osseointegration
- Designed teeth to prevent implant displacement
- Ability to pass a pin through the prosthesis
- Suitable alternative to allograft
Other advantages of these implants include their design based on the patient’s anatomy. These prostheses are available in thicknesses of 6, 8, and 10 millimeters and can be used in Evans osteotomy surgery.
The teeth designed on the implant prevent displacement, eliminating the need for alternative fixation methods. As shown in the animation, specialized tools are designed to assist the surgeon during the procedure, making the placement of the prosthesis simpler and more efficient.
