The summary describes a physical medical device (external fixation screw) with a specific coating and provides performance data related to its mechanical properties and biological interaction with bone. There is no mention of software, algorithms, image processing, or terms related to AI/ML.
Yes
The device is an external fixation screw used to fix bone, which directly treats a condition (bone trauma or instability) to restore function.
No
The device, an external fixation screw, is used for the physical external fixation of bone, not for diagnosing a condition.
No
The device description clearly states it is a physical screw manufactured from surgical grade stainless steel with a hydroxyapatite coating. It is a hardware device, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is "external fixation of bone." This is a surgical procedure performed directly on the patient's body.
- Device Description: The device is a physical screw (pin) designed to be implanted into bone.
- Lack of IVD Characteristics: There is no mention of the device being used to examine specimens derived from the human body (like blood, urine, tissue, etc.) to provide information for diagnosis, monitoring, or compatibility testing.
IVD devices are used in vitro (outside the body) to analyze samples. This device is used in vivo (inside the body) for structural support.

Device Description
The Orthofix Hydroxyapatite Coated Screws are manufactured from surgical grade stainless steel AISI 316L. The pins are available in a variety of diameters and lengths. The threaded end is gradually tapered, over approximately the last third of the pin's length. The threaded portion of the pin is coated with a very thin plasma sprayed coating of HA. The HA powder used in the plasma spray coating process conforms to ASTM F 1185. The mechanical properties of the coating conform to ASTM F 1501.

Summary of Performance Studies
The substantial equivalence of the Orthofix HA coated pins is supported by the extensive laboratory, animal and clinical testing data presented herein. The preclinical and clinical data presented herein demonstrate that the use of the proprietary HAcoating enhances fixation at the pin/bone interface. The Orthofix HA-coated pins demonstrate statistically significantly better stability or fixation at the time of removal or extraction than do the uncoated pins.
Orthofix pins with the proprietary HA-coating were found in randomized controlled clinical and animal studies to have significantly enhanced fixation and a reduced incidenced of clinical loosening. The clinical results demonstrate:
- No significant difference in the insertion torques for standard uncoated and HA-● coated Orthofix pins in both metaphyseal and diaphyseal bone.
- The extraction torque is significantly greater for HA-coated Orthofix pins than for ● uncoated pins in both metaphyseal and diaphyseal bone.
- For the HA-coated Orthofix pins, the extraction torque is significantly greater than . the insertion torque in both metaphyseal and diaphyseal bone; whereas, for the uncoated pins, the extraction torque is significantly lower than the insertion torque in both metaphyseal and diaphyseal bone.
The animal study that was conducted compared uncoated and HA-coated Orthofix pins. Radiographic, histologic, SEM and histomorphometric analyses demonstrate that osseointegration with direct contact between the bone and the screw threads of the Orthofix HA-coated pins.
As reported in the literature, complications of external fixation include pin tract infection and loosening. The enhanced fixation and improved stability at the bonepin interface seen with the Orthofix Ha-coated pins significantly reduces the incidence of pin loosening. It is generally accepted that a loose pin provides an increased risk of infection.

§ 888.3040 Smooth or threaded metallic bone fixation fastener.
(a)
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.(b)

Substantial Equivalence 7.
The decision that the Orthofix HA coated pin is substantially equivalent to a legally marketed predicate device is reached through consideration of the requirements for substantial equivalence determinations. These requirements are set forth in the document entitled "Guidance on the Center for Devices and Radiological Health's Premarket Notification Review Program", which was published on June 30, 1986 by the Center for Devices and Radiological Health (CDRH),
FDA guidance documents relevant to this application were used in its preparation. In particular, the guidance document, "510(k) Information Needed for Hydroxyapatite Coated Orthopedic Implants" (revised February 20.1997), was followed in the preparation of this 510(k). The physical, mechanical and chemical tests prescribed by FDA in its guidance document to characterize the HA coating and HA/substrate interface were conducted.
The substantial equivalence of the Orthofix HA coated pins is supported by the extensive laboratory, animal and clinical testing data presented herein. The preclinical and clinical data presented herein demonstrate that the use of the proprietary HAcoating enhances fixation at the pin/bone interface. The Orthofix HA-coated pins demonstrate statistically significantly better stability or fixation at the time of removal or extraction than do the uncoated pins.
Orthofix pins with the proprietary HA-coating were found in randomized controlled clinical and animal studies to have significantly enhanced fixation and a reduced incidenced of clinical loosening. The clinical results demonstrate:
- No significant difference in the insertion torques for standard uncoated and HA-● coated Orthofix pins in both metaphyseal and diaphyseal bone.
- The extraction torque is significantly greater for HA-coated Orthofix pins than for ● uncoated pins in both metaphyseal and diaphyseal bone.

- For the HA-coated Orthofix pins, the extraction torque is significantly greater than . the insertion torque in both metaphyseal and diaphyseal bone; whereas, for the uncoated pins, the extraction torque is significantly lower than the insertion torque in both metaphyseal and diaphyseal bone.
The animal study that was conducted compared uncoated and HA-coated Orthofix pins. Radiographic, histologic, SEM and histomorphometric analyses demonstrate that osseointegration with direct contact between the bone and the screw threads of the Orthofix HA-coated pins.
As reported in the literature, complications of external fixation include pin tract infection and loosening. The enhanced fixation and improved stability at the bonepin interface seen with the Orthofix Ha-coated pins significantly reduces the incidence of pin loosening. It is generally accepted that a loose pin provides an increased risk of infection.
In summary, the information and data provided in this submission are consistent with FDA's guidance documents for HA coated orthopedic implants and demonstrate that the Orthofix HA coated pin is substantially equivalent to legally marketed predicate devices.
