Intended Use

The StayFuse is a screw device designed for small bone fusion and fractures. It is indicated for fractures, and inter-digital fusion of the fingers, toes and small bones.

Device Story

StayFuse is an intramedullary bone screw consisting of two components: a male half with a protruding connection and a female half with an internal connection. The bone-mating portion features a cancellous thread with a self-drilling and tapping tip. An external hex distal to the screw tip allows engagement with a dual-purpose hex driver, which is used for both pre-drilling the bone and inserting the implant. The driver is designed to interface with a standard cannulated drill chuck. The device is available in various diameters, lengths, and hex drive configurations to accommodate bone size variability. It is intended for use by clinicians for small bone fusion and fracture fixation. Not intended for spinal use.

Clinical Evidence

bench testing only

Technological Characteristics

Intramedullary bone screw; cancellous thread design; self-drilling/tapping tip; external hex interface; dual-purpose hex driver; cannulated drill compatibility; various diameters and lengths.

Indications for Use

Indicated for fractures and inter-digital fusion of fingers, toes, and small bones.

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.

#### Device Description

The StayFuse is a device consisting of two components. The male half possesses a protruding connection feature and the female half an internal connection feature. The bone-mating portion has a cancellous type thread with a self-drilling and tapping tip. Distal to the screw tip is an external hex that is engaged with a hex driver. The hex driver is dual purpose: one end shaped for pre-drilling the bone and the other end features an internal hex for inserting the implant. The hex driver is designed to interface with a chuck of a standard cannulated drill. The implant will be offered in a number of diameters, lengths and hex drives to accommodate the variability in bone sizes.

#### Intended Use

The StayFuse is a screw device designed for small bone fusion and fractures. It is indicated for fractures, and inter-digital fusion of the fingers, toes and small bones.

#### Performance Data

The Pioneer StayFuse Implant was predicated on the use of K-Wires.
