The description focuses on the materials, dimensions, and intended surgical use of a mechanical orthopedic implant. There is no mention of software, algorithms, or data processing that would indicate AI/ML.
Yes.
The device is an orthopedic implant for partial or total replacement of the human shoulder joint. It is used to treat various conditions such as complex fractures, avascular necrosis, and arthritis, falling under the definition of a therapeutic device designed to alleviate or cure medical conditions.
No
The Neer III Total Shoulder System is an orthopedic implant for joint replacement, not a diagnostic tool. Its purpose is to replace or articulate parts of the shoulder joint, as indicated by its uses for fractures, avascular necrosis, and arthritis.
No
The device description clearly states the device is manufactured from cast CoCr alloy and is an orthopedic implant, indicating it is a physical hardware device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information for diagnosis, monitoring, or screening.
- Device Description: The Neer III Total Shoulder System is an orthopedic implant designed for the surgical replacement of the human shoulder joint. It is a physical device implanted into the body.
- Intended Use: The intended use clearly describes its function as a replacement for the shoulder joint in various conditions like fractures, arthritis, and avascular necrosis. This is a surgical intervention, not a diagnostic test performed on a specimen.
The provided information describes a surgical implant, not a device used for testing biological samples outside of the body.

Intended Use / Indications for Use
The Neer III Total Shoulder System is indicated for use as an orthopedic implant for the partial or total replacement of the human shoulder joint articulating either directly against the glenoid face or a compatible glenoid component, respectively.
The Neer III Total Shoulder System is intended for the following:
Proximal Humeral Prosthesis - (1) complex, acute fracture-dislocations of the humeral head (e.g., trauma - three and four-part injuries in the Neer classification, or head impression fractures); (2) complex, chronic fractures or fracture-dislocations of the humeral head with malunion, nonunion of a small osteoporotic head fragment, or chronic dislocation with loss of humeral head cartilage, or large impression fractures; (3) avascular necrosis with intact glenoid cartilage; and (4) selected patients with arthritis who do not have adequate scapular bone to support a glenoid component or must engage in moderately heavy activities.
Total Shoulder Arthroplasty (when used in conjunction with a compatible glenoid component) – severe destruction of the glenohumeral articular surfaces with intractable chronic pain in rheumatoid arthritis, osteoarthritis, traumatic arthritis, cuff tear arthroplasty, ancient septic arthritis, avascular necrosis with secondary glenoid changes, radiation necrosis, and other failed reconstructive procedures.
This device is intended only for cemented fixation.

Device Description
Neer III humeral stems are manufactured from cast CoCr (cobalt chrome) alloy and are available in three stem diameters (8, 10 & 12mm). Four head heights, 15, 19, 22 & 26mm, are available, to allow accurate tensioning of the joint intra-operatively. The 25mm radius of curvature of the heads is constant throughout the stem to be used as a total shoulder replacement in conjunction with various glenoid components. Suture-wire holes are located in two laterally orientated fins to optimize re-attachment of the tuberosities.
The implants in the system are intended fixation into a prepared humeral canal. Neer III humeral stems can be used in conjunction with a compatible glenoid component, such as Neer II Shoulder glenoid components, Coffeld Modular Shoulder glenoid components, Anatomic glenoid components, or in a hem-arthroplasty against an unresurfaced glenoid process.

§ 888.3660 Shoulder joint metal/polymer semi-constrained cemented prosthesis.
(a)
Identification. A shoulder joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a shoulder joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a humeral resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a glenoid resurfacing component made of ultra-high molecular weight polyethylene, and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II. The special controls for this device are:(1) FDA's:

Substantial Equivalent Information
The Neer III Total Shoulder System is similar to the following shoulder systems:
-
- Neer II Total Shoulder System 3M
-
- Modular Total Shoulder System - 3M
-
- Aequalis Shoulder System - Tornier S.A.
All of the devices listed above are indicated for the same use as total shoulder systems, and are similar in design to the Neer III Total Shoulder System. The safety and effectiveness of the Neer III Total Shoulder System is based on the long history of use of these devices in the market place.
Device Description
Neer III humeral stems are manufactured from cast CoCr (cobalt chrome) alloy and are available in three stem diameters (8, 10 & 12mm). Four head heights, 15, 19, 22 & 26mm, are available, to allow accurate tensioning of the joint intra-operatively. The 25mm radius of curvature of the heads is constant throughout the stem to be used as a total shoulder replacement in conjunction with various glenoid components. Suture-wire holes are located in two laterally orientated fins to optimize re-attachment of the tuberosities.
The implants in the system are intended fixation into a prepared humeral canal. Neer III humeral stems can be used in conjunction with a compatible glenoid component, such as Neer II Shoulder glenoid components, Coffeld Modular Shoulder glenoid components, Anatomic glenoid components, or in a hem-arthroplasty against an unresurfaced glenoid process.
Indications for Use
The Neer III Total Shoulder System is indicated for use as an orthopedic implant for the replacement of the human shoulder joint articulating either directly against the glenoid face or a compatible glenoid component, respectively,
The Neer III Total Shoulder System is intended for the following:
Proximal Humeral Prosthesis - (1) complex, acute fracture-dislocations of the humeral head (e.g., trauma - three and four-part injuries in the Neer classification, or head impression fractures); (2) complex, chronic fractures or fracture-dislocations of the humeral head with malunion of a small osteoporotic head fragment, or chronic dislocation with loss of humeral head cartilage, or large impression fractures; (3) avascular necrosis with intact glenoid cartilage; and (4) selected patients with arthritis who do not have adequate scapport a glenoid component or must engage in moderately heavy activities.
Total Shoulder Arthroplasty (when used in compatible glenoid component) - severe destruction of the glenohumeral articular surfaces with intractable chronic pain in rheumatoid arthritis, traumatic arthritis, cuff tear arthroplasty, ancient septic arthritis, avascular necrosis with secondary glenoid changes, radiation necrosis, and other failed reconstructive procedures.
This device is intended only for cemented fixation.
Technological Characteristics:
The Neer III Total Shoulder System is substantially equivalent to the above predicate devices. The Neer is a modification of the Neer II device and has the same technological characteristics as the Neer predicate devices. Range of Motion, finite element analysis, fatigue testing, stem strength, and package integrity testing were performed on the Neer III prosthesis. Test results were consistent with the Neer II and predicate devices. The Anatomic Glenoid is substantially equivalent to the Neer II UHMWPE glenoid component predicate device. It is manufactured of the same material with the only difference being a more anatomical "pear-shaped" design.
