INnate Intramedullary Threaded Nail System

Overview

The INnate Intramedullary Threaded Nail system features a dual diameter, stainless steel nail with a noncompressive construct to achieve canal fill and stable fixation of metacarpal fractures, avoiding complications such as shortening, and delivering minimal soft tissue damage and early to immediate range of motion. The robust length and diameter offering allows for precise anatomic reduction of all fracture types and locations.

Indications for Use

The INnate Intramedullary Threaded Nail System is intended for fixation of intra-articular and extra-articular fractures and nonunions of small bones and small bone fragments; arthrodesis of small joints; bunionectomies and osteotomies, including scaphoid and other carpal bones, metacarpals, tarsals, metatarsals, patella, ulnar styloid, capitellum, radial head, and radial styloid.

A New Standard for Metacarpal Fracture Fixation

An intramedullary threaded nail designed specifically for metacarpal fractures, Innate is intended to provide a reliable solution through a simple, minimally invasive approach. The extensive length offering with a differential diameter accurately fits the metacarpal canal and to create stable fixation and precise reduction for all types of metacarpal fractures.

The system is provided sterile-packed. The implants are single-use, while separate disposable instruments kits are available, specific to the implant diameter selected.

INnate Metatarsal Surgical Technique

Image

The INnate System introduces an intramedullary (IM) threaded nail for metatarsal fractures to provide surgeons with a reliable solution through a simple approach.

The robust length offering with a differential diameter design is intended to accurately fit the intramedullary canal and to create stable fixation and precise reduction for nearly all types of metatarsal fractures.
