Clinical Trial Summary

Many approaches to the surgical treatment of OF-P have been tried, but no one method has stood out as particularly successful. The placement of three implants, including implants that could minimise motion in the sacroiliac joint through early fixation and long-term fusion of the sacroiliac joint, can prevent micromotion in the fracture and thereby improve the clinical outcome of OF-Ps.

The iFuse-3D implant was shown to be safe and effective for chronic sacroiliac pain in non-osteoporotic patients.

The primary aim is to assess the proportion of patients operated on using iFuse-3D in conjunction with transiliac-transsacral screws who regain pre-fracture mobility by the time of hospital discharge.

Intervention

Device:
• iFuse-3D implant
The iFuse Implant System consists of cannulated triangular titanium implants (Ti 6AI4V ELI, ASTM F136) with a porous coating of commercially pure titanium plasma spray (C.P. Ti, ASTM F1580) and a setting instrument. The coating and special shape of the implants prevent rotation or displacement of the sacroiliac (SI) joint. The placement instrument uses guide pins to achieve precise placement.
