Curved implant for curved bones of the pelvis
The CurvaFix® IM Implant is the first, new intramedullary pelvic trauma technology in 30 years, and is the only device capable of following the natural bone shape and filling the space within the pelvis. Unlike straight screws which can’t follow the natural curvature of intramedullary pathways (limiting use), and bone plates which require an invasive and costly, open surgical procedure, the CurvaFix IM Implant provides a new state-of-the-art option for pelvic fracture repair.

Anticipated benefits of the patented1 CurvaFix solution:
Stronger, more stable fixation
may be achieved by holding fracture alignment with a longer, curved implant
Shorter surgery
may be realized with average procedure time reduced by an hour and saving more than $6,000 compared to bone plates2
Faster recovery
may result from load sharing during bone healing, similar to intramedullary rods3
Better outcomes
may help elderly patients avoid nursing home care by enabling strong fixation in weak bones with minimally invasive surgery4,5

Flexible state: Cables slide freely in lock

Rigid state: Cables held in lock

STRAIGHT:
4 cables, same lengths in proximal end

Cables welded into distal end

CURVED:
4 cables locked at different lengths

Cables welded into distal end

The design of the CurvaFix IM Implant includes:
- Threaded, self- tapping distal end
- Proximal end feature for driving torque
- Patented lock feature that converts the flexible implant to a rigid state during implantation, stabilizing and repairing a bone fracture
The CurvaFix implant’s patented technology functions similarly to a suspension bridge, using tension and transfer of force to create stability. The implant has four internal cables that allow it to be flexible as it’s tracked over a steerable guidewire to the fracture. Once the implant is in place, the surgeon locks the cables, and the implant becomes rigid.
In the anatomy with the cables locked, the CurvaFix Implant is intended to distribute force more evenly across the bone—to maintain fracture reduction and provide stronger, more stable fixation.

Implantation and Locking
Familiar, rapidly adoptable procedure
The CurvaFix IM Implant procedure is minimally invasive and performed under standard fluoroscopy. The flexible device is implanted through a small incision over a steerable guidewire into the intramedullary space (center of the bone). The implant is then tracked over the guidewire and locked in shape using the patented lock feature near the head of the implant.
The procedure can be completed in as little as 20 minutes and is intended to yield strong, stable fixation.


Real-world case studies and clinical results
The CurvaFix IM Implant provides a revolutionary option for physicians and patients in treating pelvic fractures, and is intended to achieve faster, more successful recoveries.
