The document describes a mechanical hip replacement system and its surgical implantation process. There is no mention of AI or ML in the device description, intended use, or performance studies.
Yes
The device is a hip replacement system intended to restore the function of a severely disabled and/or very painful hip joint.
No
Explanation: The device is a hip replacement system, an implantable medical device used for surgical reconstruction of the hip joint. Its purpose is treatment, not diagnosis. While it mentions "radiographic evidence" for patient selection, the device itself does not perform diagnostic functions.
No
The device description clearly outlines physical components of a hip replacement system, including a femoral stem, neck component, and instruments for insertion and extraction. This indicates it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- Device Description: The Margron™ Hip Replacement System is a physical implant designed to replace the femoral portion of a hip joint. It is a surgical device, not a diagnostic test.
- Intended Use: The intended use is for surgical reconstruction of a hip joint, not for diagnosing a condition using a sample from the body.
- Input: The input mentioned is "radiographic evidence," which is an imaging modality used for surgical planning and assessment, not a biological sample for in vitro testing.
Therefore, the Margron™ Hip Replacement System falls under the category of a surgical implant or prosthesis, not an In Vitro Diagnostic device.
N/A
Intended Use / Indications for Use
The Margron™ Hip Replacement System is intended for primary or revision restruction, without bone cement, of the femoral portion of a severely disabled and/or very painful hip joint, where radiographic evidence of sufficient sound bone is present.
The patient should be skeletally mature. The patient's condition should be due to one or more of the following:
- Osteoarthritis ●
- Rheumatoid arthritis
- Ankylosing spondylitis
- Psoriatic arthritis ●
- Old osteomyelitis with a long infection free period and a normal WBC, C-. Reactive protein and ESR
- Non union of femoral neck fracture or avascular necrosis of the femoral head
- Post-traumatic fracture/dislocation of the hip
- Revision of an unsuccessful arthrodesis with either poor positioning or pain in the hip, or where low back pain or knee pain is becoming disabling
- Revision of an unsuccessful uncemented or cemented hip replacement stem, ● providing sufficient bone stock is present
- Revision of a previous unsuccessful femoral osteotomy, Girdlestone resection, . cup arthroplasty or hemi arthroplasty.

Device Description
The Margron™ hip replacement stem has been designed to be used in an uncemented mode in bone which is of good quality physiologically and which will heal quickly.
The Margron™ Femoral Stem is a modular prosthesis consisting of:
- A tapering stem cone with two different speed external threads and longitudinal . derotation columns.
- A neck component which allows the optimum angle of anteversion to be selected . after stem insertion.
- . Precision milling and tapping is used to prepare the femur, and stem insertion is by 'screw home' rotation.
- A unique set of instruments have been designed to insert and extract the . prosthesis.

§ 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)

Dear Dr. Sekel:
We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.
If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
