The document describes a physical medical device (femoral stems for hip replacement) and its design modifications. There is no mention of software, algorithms, data processing, or any terms related to AI/ML. The performance studies focus on mechanical testing of the physical components.
Yes
The device is a component of a total hip prosthesis system intended for hip replacement surgery, which is a therapeutic intervention for painful and disabled joints.
No
Explanation: The device described is a hip prosthesis system, which is an implant used for hip replacement surgery. It is a treatment device, not one used for diagnosis.
No
The device description clearly states that the device is a physical implant (femoral stems) made of forged stainless steel. 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:
- 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 detect diseases, conditions, or infections.
- Device Description and Intended Use: The description clearly states that this device is a femoral stem, which is an implantable component of a total hip prosthesis system. Its intended use is for surgical implantation in the hip joint to replace damaged bone.
- Lack of Diagnostic Function: The device does not perform any tests on biological samples. It is a mechanical implant designed to restore function to the hip joint.
Therefore, the Medacta Total Hip Prosthesis System – Quadra C Femoral Stems are a surgical implant, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Medacta Total Hip Prosthesis System – Quadra C Femoral Stems are intended for cemented use in total or partial hip arthroplasty and in primary or revision surgery.
Hip replacement is indicated in the following cases:
- Severely painful and/or disabled joint as a result of arthritis, traumatic arthritis, rheumatoid polyarthritis, or congenital hip dysplasia
- Avascular necrosis of the femoral head
- Acute traumatic fracture of the femoral head or neck
- Failure of previous hip surgery, joint reconstruction, internal fixation, arthrodesis, hemiarthroplasty, surface replacement arthroplasty, or total hip replacement.
Size 0 implants should not be implanted in patients with a mass of 65 kg or greater.

Device Description
This modification to the original Medacta Total Hip Prosthesis System -Quadra C femoral stems is a line extension to include the AMIStem C femoral stems and Quadra C Short Neck (SN) femoral stems. AMIStem C femoral stems are based on the design of the Quadra C femoral stems in the original submission. The AMIStem C femoral stems differ from the Quadra C femoral stems by a decreased length of 15% and a reduced shoulder. The Quadra C short neck femoral stems are the same design femoral stems as the Quadra C femoral stems in the original submission but the length of the neck that is 5 mm shorter.
Like the Quadra C femoral stems, the AMIStem C femoral stems and the Quadra C SN femoral stems are highly polished, collarless femoral components manufactured from forged stainless steel according to ISO 5832-9. The AMIStem C femoral stems and the Quadra C SN femoral stems are straight quadratic stems with a triple taper shape. The proximal portion of the stem has a standard 12/14 taper for mechanical attachment to cleared Medacta International metallic or ceramic femoral heads.
Like the Quadra C femoral stems, two different caput-collum-diaphyseal angles (CCD) are available for the AMIStem C femoral stems and the Quadra C Short neck femoral stems: 135° for the standard offset and 127° for the lateralized offset. The Quadra C short neck femoral stems come in eight sizes with a standard offset and seven sizes with a lateral offset. The AMIStem C femoral stems come in eight sizes with a standard offset and seven sizes with a lateral offset. There are no short neck versions for the AMIStem C femoral stems.
The AMIStem C femoral stems and the Quadra C short neck femoral stems provide additional femoral stem options to the surgeon for use with the Medacta Total Hip Prosthesis System.

Performance Testing:
A detailed list is provided in Section 18 Performance Testing - Bench.
The modifications to the device system to include the addition of AMIStem C and Quadra C short neck femoral stems were evaluated by risk analysis to identify any new risks associated with these changes. Based on the risk analysis, design verification was conducted to written protocols with predefined acceptance criteria. The protocols and pre-defined acceptance criteria were based on the standards and FDA guidance. The testing was conducted on the worst case based on engineering analysis. The testing included endurance testing of the neck and stem regions of the femoral components as well as range of motion analysis. The design verification activities met all acceptance criteria and verified the performance of the Medacta Total Hip Prosthesis System - AMIStem C femoral stems and Quadra C short neck femoral stems.

§ 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.
