Intended Use
The Compass Universal Hinge is a line extension to the Ilizarov external fixation system. It is used in conjunction with the Ilizarov system to treat joint contractures and to restore mobility and function of a joint that has become stiff due to contracture or traumatic injury. The Compass Universal Hinge construct is indicated to treat post-traumatic joint contracture which has resulted in the loss of range of motion, and fractures and disease which generally may result in joint contracture or loss of range of motion.
Device Description
The Compass Universal Hinge is a device used with external fixation devices for the indications listed previously. The Compass Universal Hinge is applied to bones on both sides of a joint to provide active and passive motion of the joint and to restore loss of range of motion due to contracture.

No
The summary describes a mechanical device used with an external fixation system and makes no mention of AI or ML technology.

Yes
The device is used to treat joint contractures and restore mobility and function of a joint, which are therapeutic actions.

No
The device is described as a treatment device used for joint contractures and to restore mobility and function. It does not mention diagnosing conditions.

No

The device description clearly states it is a "device used with external fixation devices" and is "applied to bones on both sides of a joint," indicating it is a physical hardware component, not software.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to provide information about a person's health.
  • Device Function: The Compass Universal Hinge is a mechanical device used externally to treat joint contractures and restore range of motion. It is applied to bones and facilitates physical movement of the joint.
  • Lack of Biological Sample Testing: The description clearly states its use in conjunction with an external fixation system for physical manipulation of a joint. There is no mention of testing biological samples.

Therefore, based on the provided information, the Compass Universal Hinge falls under the category of a surgical or orthopedic device, not an In Vitro Diagnostic.

§ 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)
Classification. Class II.

Summary of Safety and Effectiveness Compass Universal Hinge

Substantial Equivalence Information

The Compass Universal Hinge is similar to Smith & Nephew's Ilizarov External Fixator and Howmedica's Dynamic Joint Distractor. All of these devices use external fixation to treat joint contracture or fractures and diseases that may lead to joint contracture. The Compass Universal Hinge represents improvements that enhance user convenience.

Device Description

The Compass Universal Hinge is a device used with external fixation devices for the indications listed previously. The Compass Universal Hinge is applied to bones on both sides of a joint to provide active and passive motion of the joint and to restore loss of range of motion due to contracture.

Indications for Use

The Compass Universal Hinge is a line extension to the Ilizarov external fixation system. It is used in conjunction with the Ilizarov system to treat joint contractures and to restore mobility and function of a joint that has become stiff due to contracture or traumatic injury. The Compass Universal Hinge construct is indicated to treat post-traumatic joint contracture which has resulted in the loss of range of motion, and fractures and disease which generally may result in joint contracture or loss of range of motion.
