Intended Use

InFix Cannulated Screw System is generally intended for fracture fixation of various bones and bone fragments, such as femoral neck, intercondylar femoral, malleolus, pilon tibial, calcaneus, talus, tibial plateau, tarsal, metacarpal, carpal, scaphoid and radius fracture. InFix Cannulated Screw System is also intended for fixation arthrodesis, iliosacral dislocations, and hallux valgus corrections. Accessories implants: The round washer is used to increase bone contact area for distributing the forces/load and prevent the screw head from sinking into the bone.

Device Story

InFix Cannulated Screw System consists of cannulated, self-tapping, self-drilling screws and washers; used for skeletal fracture alignment and stabilization. Implants guided into position via guide wire. Used in clinical settings by orthopedic surgeons. Washers distribute load and prevent screw head subsidence. Device provides mechanical fixation to facilitate bone healing.

Clinical Evidence

No clinical data provided. Substantial equivalence established via non-clinical biomechanical testing (ASTM F543), cleaning validation (AAMI TIR30:2011), and sterilization validation (ANSI/AAMI/ISO 17665-1).

Technological Characteristics

Materials: Stainless steel 316L (ASTM F138) and Ti-6Al-4V alloy (ASTM F136). Design: Cannulated, self-tapping, self-drilling screws with cancellous threads. Includes associated washers. Not MR safe/compatible.

Indications for Use

Indicated for fracture fixation of various bones and bone fragments (femoral neck, intercondylar femoral, malleolus, pilon tibial, calcaneus, talus, tibial plateau, tarsal, metatarsal, wrist, metacarpal, carpal, scaphoid, radius), fixation arthrodesis, iliosacral dislocations, and hallux valgus corrections.

Regulatory Classification

Identification

A smooth or threaded metallic bone fixation fastener is a device intended to be implanted that consists of a stiff wire segment or rod made of alloys, such as cobalt-chromium-molybdenum and stainless steel, and that may be smooth on the outside, fully or partially threaded, straight or U-shaped; and may be either blunt pointed, sharp pointed, or have a formed, slotted head on the end. It may be used for fixation of bone fractures, for bone reconstructions, as a guide pin for insertion of other implants, or it may be implanted through the skin so that a pulling force (traction) may be applied to the skeletal system.
