Intended Use
1) Relief of severe pain or significant disability in degenerative, rheumatoid, or traumatic disease of the clenohumeral joint. 2) Irreducible 3 and 4 part fractures of the proximal humerus. 3) Non-united chronic humeral head fractures or fracture-dislocations. 4) Avascular necrosis of the humeral head. 5) Other difficult clinical management problems, including falled reconstructive procedures, where arthrodesis of resection arthroplasty are not considered acceptable.
Device Description
The Kirschner Shoulders are all based on the original design concept of the Neer Shoulder. Common design features include Cobalt-Chromium-Molybdenum alloy substrate: smooth. distally tapered stem; grooves in the stem to aid in cement pressurization and provided torsional stability; four proximal fins to provided rotational stability and facilitate positioning insertion; continuous radius of curvature humeral head geometry and; all humeral heads are compatible with all glenoid components. Kirschner II-C Humeral Stems are one piece in that the head and stern are an single component. Modular II-C Humeral Stems are a one piece stem with a modular head attached by a Morse-type taper. Atlas-C Modular Stems are two piece stems composed of a proximal humeral component and a distal stem attached by a screw thread. This component also utilizes a modular humeral head. The Modular Glenoid Metal Backing provides reinforcement to a polyethylene bearing surface. The design is identical to the predicate device. This 510(k) is for a change from a cobalt alloy plasma spray coating to a titanium alloy coating and a change in the manufacturing location. All other aspects of the device remain the same.
More Information

No
The device description focuses on material changes and manufacturing location, with no mention of AI or ML capabilities. The "Mentions AI, DNN, or ML" field is explicitly marked as "Not Found".

Yes
The device is described as an artificial joint replacement for the shoulder, intended to relieve pain and address conditions like fractures and avascular necrosis. These are all therapeutic purposes.

No

The device is a shoulder implant designed for the relief of pain or disability in the clenohumeral joint due to various conditions, or for the treatment of fractures and other complicated management problems. It is a prosthetic device for repair or replacement, not for diagnosing a condition.

No

The device description clearly describes physical implants made of metal alloys (Cobalt-Chromium-Molybdenum alloy, titanium alloy) intended for surgical implantation in the shoulder joint. This is a hardware medical device.

Based on the provided text, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The intended use describes the device as a surgical implant for treating conditions of the shoulder joint (clenohumeral joint, proximal humerus, humeral head). This is a therapeutic device used in vivo (within the body).
  • Device Description: The device description details the physical components of a shoulder implant (stems, heads, glenoid components) made of metal alloys. This is consistent with a surgical implant, not a diagnostic test performed in vitro (outside the body).
  • Lack of IVD Characteristics: There is no mention of the device being used to examine specimens from the human body (like blood, urine, tissue), or to provide information for the diagnosis, prevention, or treatment of disease.

Therefore, this device is a surgical implant, not an In Vitro Diagnostic.

§ 888.3690 Shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis.

(a)
Identification. A shoulder joint humeral (hemi-shoulder) metallic uncemented prosthesis is a device made of alloys, such as cobalt-chromium-molybdenum. It has an intramedullary stem and is intended to be implanted to replace the articular surface of the proximal end of the humerus and to be fixed without bone cement (§ 888.3027). This device is not intended for biological fixation.(b)
Classification. Class II.
