Oliga leads innovational systems, and aims to supply options for the surgeons to excel at their expertise. Claws are a novelty solution on distal locking systems designed to support the orthopedic trauma community.
Claws are titanium pins that act as anchors to provide a stable fixation, as well as other superior operative parameters.
In unstable subtrochanteric fractures Claws provide superior rotational stability. After 10,000 cycles, the nail settled in and remained fixed until
The Claws’ performance was evaluated using a series of biomechanical tests.
All Claws were successfully retracted after every test.
Get Better Stability!
Claws have 6 points of contact with the cortical bone. The load is shared between those points, increasing the implant’s stability, and preventing secondary fractures and malunions.
Claws Axial Fatigue Strength
The average displacement observed at 1 million cycles was 0.74 mm.
Claw Axial Static Strength
Claws resist to a higher force for a given displacement, compared to conventional stainless steel screws.
The internal fixation device should promote good rotational stability to allow for quick regeneration of the bone.
Fracture gap or distraction are also important causes of nonunion.
To tackle these challenges, Oliga’s Lag Screw utilizes the Claw Technology. It presents three times more rotational stability and a two-fold increase in compression when compared to conventional systems.
3x More Rotational
2x More Compression
Virtually no cut-out
Four retractable Claws anchor the lag screw into the cortical bone of the femoral head-neck junction for superior control.
