Device Story

Treu Bone Fixation Screws and Pins are orthopedic implants used for bone fracture fixation, joint fusion, bone reconstruction, or as guide pins. Device line includes cortical, cancellous, compression, snap-off, cannulated, and Schanz screws; Kirschner wires; Steinmann pins; and Larsen pins. Inputs are surgical site anatomy; device provides mechanical stabilization of bone segments. Used in clinical/surgical settings by orthopedic surgeons. Output is physical fixation of bone; aids in healing/stabilization. Materials include stainless steel or titanium alloy. Devices vary by diameter (0.8mm–7mm) and length (6mm–500mm).

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Metallic bone fixation fasteners (screws/pins). Materials: stainless steel or titanium alloy. Dimensions: diameters 0.8mm–7mm, lengths 6mm–500mm. Configurations: cannulated/non-cannulated, smooth/threaded. Mechanical fixation principle. Class II device per 21 CFR 888.3040.

Indications for Use

Indicated for patients requiring bone fracture fixation, joint fusion, bone reconstruction, or use as guide pins for implant insertion.

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.
