Intended Use

Synthes Hydroxyapatite (HA) Coated Schanz Screws are intended for use with an external fixation system for fracture fixation (open and closed); pseudoarthrosis or non-union of long bones; limb lengthening by epiphyseal or metaphyseal distraction; correction of bony or soft tissue deformity; correction of segmental bony or soft tissue defects; and joint arthrodesis.

Device Story

Synthes HA Coated Schanz Screws are metallic bone fixation fasteners used in external fixation systems. Available in self-drilling and non-self-drilling designs with various diameters and lengths. The threaded portion features a thin plasma-sprayed hydroxyapatite (HA) coating. Used by surgeons in clinical settings to stabilize bone fractures, correct deformities, or facilitate limb lengthening. The device provides mechanical fixation to bone, aiding in stabilization and healing.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Materials: Titanium and stainless steel. Design: Smooth or threaded metallic bone fixation fastener with plasma-sprayed hydroxyapatite coating. Available in self-drilling and non-self-drilling configurations.

Indications for Use

Indicated for patients requiring external fixation for fracture fixation (open/closed), non-union/pseudoarthrosis of long bones, limb lengthening, correction of bony/soft tissue deformities or defects, and joint arthrodesis.

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.
