No
This device is described as an "Allofit 32mm Alpha Durasul Insert," which is a component used in total hip arthroplasty (joint replacement surgery). Its purpose is to be implanted into the body as a replacement part, not to diagnose a condition.
No
The device description clearly details physical components (inserts, shells, covers, instrumentation) made of materials like titanium and polyethylene, intended for surgical implantation. There is no mention of software as the primary or sole component.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes a device used in total hip arthroplasty for treating joint diseases and failed surgeries. This is a surgical implant, not a device used to examine specimens from the human body to provide information for diagnosis, monitoring, or compatibility testing.
- Device Description: The description details a physical implant component (acetabular insert) that is surgically placed within the body. IVDs are typically reagents, instruments, or systems used outside the body to analyze biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, providing diagnostic information, or any of the typical characteristics of an IVD.
Therefore, this device falls under the category of a surgical implant or prosthetic device, not an In Vitro Diagnostic.

Device Description
This Special 510(k) submission seeks to obtain clearance for addition of the Allofit 32mm Alpha Durasul Inserts to the existing, previously cleared (K003578) Allofit 28mm Alpha Durasul Insert product line. The only difference from the existing product is the internal diameter of the insert (32mm vs. 28mm). There are also no changes to the other previously cleared components of the system which are used in conjunction with the inserts (e.g, acetabular shells, dome hole covers, screw hole covers, instrumentation). The Allofit 32mm Alpha Durasul inserts incorporate the same general design features as the existing, previously cleared Allofit 28mm Alpha Durasul insert components and Allofit 32mm Alpha inserts (standard Sulene polyethylene). The inserts are snapped into the respective Allofit titanium shell intraoperatively. A peripheral locking mechanism holds the insert within the shell. A peg shaped eminence at the apex of the insert slips into the dome hole of the shell and provides further stability of the insert within the shell. Upon impaction into the short spikes in the dome of the metallic shell minimally penetrate the polyethylene insert, providing additional resistance to rotation. Both a standard and hooded insert configuration will continue to be offered. The Allofit 32mm Alpha Durasul inserts will also use the same materials as the previously cleared devices (ISO 5834-1/2). The Durasul material is identical to that which was previously characterized and cleared for use in the Allofit 28mm Alpha Durasul Inserts.

§ 888.3353 Hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis.
(a)
Identification. A hip joint metal/ceramic/polymer semi-constrained cemented or nonporous uncemented prosthesis is a device intended to be implanted to replace a hip joint. This device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. The two-part femoral component consists of a femoral stem made of alloys to be fixed in the intramedullary canal of the femur by impaction with or without use of bone cement. The proximal end of the femoral stem is tapered with a surface that ensures positive locking with the spherical ceramic (aluminium oxide, A12 03 ) head of the femoral component. The acetabular component is made of ultra-high molecular weight polyethylene or ultra-high molecular weight polyethylene reinforced with nonporous metal alloys, and used with or without bone cement.(b)
Classification. Class II.

PRODUCT DESCRIPTION
This Special 510(k) submission seeks to obtain clearance for addition of the Allofit 32mm Alpha Durasul Inserts to the existing, previously cleared (K003578) Allofit 28mm Alpha Durasul Insert product line. The only difference from the existing product is the internal diameter of the insert (32mm vs. 28mm).
There are also no changes to the other previously cleared components of the system which are used in conjunction with the inserts (e.g, acetabular shells, dome hole covers, screw hole covers, instrumentation).
The Allofit 32mm Alpha Durasul inserts incorporate the same general design features as the existing, previously cleared Allofit 28mm Alpha Durasul insert components and Allofit 32mm Alpha inserts (standard Sulene polyethylene). The inserts are snapped into the respective Allofit titanium shell intraoperatively. A peripheral locking mechanism holds the insert within the shell. A peg shaped eminence at the apex of the insert slips into the dome hole of the shell and provides further stability of the insert within the shell. Upon impaction into the short spikes in the dome of the metallic shell minimally penetrate the polyethylene insert, providing additional resistance to rotation. Both a standard and hooded insert configuration will continue to be offered.
The Allofit 32mm Alpha Durasul inserts will also use the same materials as the previously cleared devices (ISO 5834-1/2). The Durasul material is identical to that which was previously

characterized and cleared for use in the Allofit 28mm Alpha Durasul Inserts.
SPECIFIC DIAGNOSTIC INDICATIONS
There have been no changes in the diagnostic indications from the previously cleared components as a result of this line addition.
Components of the Allofit Acetabular System are intended for use in total hip arthroplasty for treatment of the following:
- patient conditions of noninflammatory degenerative joint disease (NIDJD); e.g., avascular . necrosis, osteoarthritis, and inflammatory joint disease (IJD), e.g., rheumatoid arthritis.
- those patients with failed previous surgery where pain, deformity, or dysfunction persists. .
- revision of a previously failed hip arthroplasty. .
SUBSTANTIAL EQUIVALENCE
Substantial equivalence is based on comparison to the previously cleared Allofit 28mm Alpha Durasul Inserts. The fundamental scientific technologies incorporated in this previously cleared design have not changed in this product line addition. The only difference in the existing Allofit Alpha Durasul Insert components and this line addition is the internal diameter (32mm vs. 28mm).
Based on conformance with the design control requirements as specified in 21 CFR 820.30 and similarities in design, materials, sterilization, packaging, instrumentation, intended use and indications for use, we believe that the Allofit 32mm Alpha Durasul Inserts are substantially equivalent to the previously cleared Allofit 28mm Alpha Durasul Inserts.
