The document describes a mechanical hip stem implant and its materials and testing, with no mention of software, algorithms, or AI/ML capabilities.
Yes
The device is a hip stem indicated for relieving pain and improving hip function in patients with various degenerative joint diseases and functional deformities. These uses qualify it as a therapeutic device.
No
Explanation: The PROFEMUR® Z Titanium Plasma Sprayed Hip Stem is an implantable medical device used in total hip arthroplasty to replace a damaged hip joint. Its purpose is therapeutic (pain reduction, improved function), not diagnostic. It does not identify a disease or condition.
No
The device description clearly describes a physical hip stem implant made of titanium alloy with a titanium plasma spray coating. It is a hardware component intended for surgical implantation.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is a hip stem used in total hip arthroplasty for the reduction or relief of pain and/or improved hip function in patients with specific conditions. This is a surgical implant used in vivo (within the body).
- Device Description: The description details a modular hip stem made of titanium alloy with a titanium plasma spray coating. This is a physical implant designed to be surgically placed in the femur.
- 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 biological samples. This device is a surgical implant used in vivo.
N/A

Device Description
The modular PROFEMUR® Z Titanium Plasma Sprayed hip stem is an uncemented distal femoral implant designed to couple with Wright Medical Technology's PROFEMUR® CoCr modular necks. The stem design was developed from the previously marketed PROFEMUR® Z Hip Stem ('STEM' K021346) and features the identical modular neck taper socket and is made of the identical Titanium alloy (ASTM F620) as previous hip stem designs by Wright.
The PROFEMUR® Z Titanium Plasma Sprayed Hip Stem leatures the identical substrate cross-sectional geometry as the PROFEMUR® Z Hip Stem (K0213146) with the addition of titanium plasma spray coating conforming to ASTM F1580 applied according to WMT specifications which covers the proximal 1/3 of the stem.

Nonclinical Testing:
The PROFEMUR® Z Titanium Plasma Sprayed Hip Stem conforms to the Guidance for Industry and FDA Staff titled "Guidance Document for Testing Orthopedic Implants with Modified Metallic Surfaces Apposing Bone or Bone Cement" issued April 28, 1994. The titanium plasma spray coating used for the PROFEMUR® Z Titanium Plasma Sprayed Hip Stem is verified by tesent within a vendor Master File. The coated stem was evaluated in distal and proximal fatigue tests according to ISO 7206-4, 6, and 8. Fretting corrosion and axial disassembly force of the coated stem were evaluated according to ASTM F1875 and F2009. Titanium Plasma Spray Coating is applied according to WMT specification and is identical to the titanium plasma spray used for the previously cleared PRO-FEMUR Hip System (K012091).
Clinical Testing:
Clinical data was not provided for the class III modular hip stem.
Conclusions:
The indications for use of the PROFEMUR® Z Titanium Plasma Sprayed are identical to the previously cleared predicate devices. The design features and materials of the subject devices are substantially equivalent to those of the predicate devices. The fundamental scientific technology of the subject device has not changed relative to the predicate devices. The safety and effectiveness of the PROFEMUR® Z Titanium Plasma Sprayed is adequately supported by the substantial equivalence information, and analysis data provided within this Premarket Notification.

§ 888.3330 Hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis.
(a)
Identification. A hip joint metal/metal semi-constrained, with an uncemented acetabular component, prosthesis is a two-part device intended to be implanted to replace a hip 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 consist of a femoral and an acetabular component, both made of alloys, such as cobalt-chromium-molybdenum. The femoral component is intended to be fixed with bone cement. The acetabular component is intended for use without bone cement (§ 888.3027).(b)
Classification. Class III.(c)
Date PMA or notice of completion of PDP is required. A PMA or a notice of completion of a PDP is required to be filed with the Food and Drug Administration on or before May 18, 2016, for any hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component that was in commercial distribution before May 28, 1976, or that has, on or before May 18, 2016, been found to be substantially equivalent to a hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component that was in commercial distribution before May 28, 1976. Any other hip joint metal/metal semi-constrained prosthesis with an uncemented acetabular component shall have an approved PMA or a declared completed PDP in effect before being placed in commercial distribution.
