No
The summary describes a physical implant device made of stainless steel and bone cement with antibiotic coating. There is no mention of software, algorithms, or any computational processing that would suggest the use of AI or ML. The performance studies focus on mechanical properties and antibiotic release, not algorithmic performance.
No
The device is a temporary spacer used in hip replacement surgery due to infection, which is subsequently replaced by a permanent device or other treatment. It aids in the surgical procedure and addresses the infection (in conjunction with antibiotics), but its primary role is as a temporary mechanical adjunct rather than a long-term therapeutic intervention in itself.
No
The device description indicates it is a "hemi-hip" style device with an outer coating of gentamicin/polymethylmethacrylate, designed for temporary use as an adjunct to total hip replacement in patients undergoing a two-stage procedure due to a septic process. Its function is to be inserted and subsequently explanted, allowing for further treatment. It does not perform any diagnostic function.
No
The device description explicitly states it is a "hemi-hip" style device with a stainless steel endoskeleton and a PMMA bone cement coating, indicating it is a physical implant, not software.
No, 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. They are used to provide information for diagnosis, monitoring, or screening.
- Spacer-G Function: The description clearly states that Spacer-G is a physical implant inserted into the body during surgery. Its purpose is to act as a temporary spacer and deliver antibiotics locally to treat an infection in the hip joint.
- Intended Use: The intended use is for temporary implantation as an adjunct to total hip replacement in patients with a septic process. This is a surgical intervention, not a diagnostic test performed on a sample outside the body.
The information provided describes a medical device used in a surgical procedure, not a diagnostic test.
N/A
Intended Use / Indications for Use
Spacer-G is indicated for temporary use (maximum 180 days) as an adjunct to total hip replacement (THR) in patients undergoing a two-stage procedure due to a septic process.
The device is inserted into the femoral medullary canal and acetabular cavity following removal of the existing femoral and acetabular implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection).
Spacer-G is not intended for use for more than 180 days, at which time it must be explanted and a permanent device implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion etc.).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance testing was conducted to verify that the implant performance would be adequate for anticipated in vivo load applications under the temporary conditions of use. The fatigue strength, static strength, wear characteristics and antibiotic release rate were evaluated and found to support the safety and effectiveness of the device.

§ 888.3360 Hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis.
(a)
Identification. A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth.(b)
Classification. Class II.

CONTRAINDICATIONS
Use of Spacer-G is contraindicated in the following situations:
- The patient's condition is such that a two-stage arthroplasty procedure is contraindicated due to decreased immune response or other relevant systemic clinical conditions.
- Lack of adequate bone structure precludes adequate support of the prosthesis in the proximal femur or acetabular region.
- The procedure is unjustified due to deficiencies in the patient's muscular, nervous or vascular systems.
- Poor bone quality (as in osteoporosis) could cause the prosthesis to migrate or to fracture host bone.
- Infection of the THR cannot be confirmed. -
- The infected THR devices cannot be removed. -
- The infecting pathogens are resistant to gentamicin. -
- The patient is sensitive (allergic) to gentamicin, aminoglycosides or PMMA bone ・ cement.
- A systemic or sccondary remote infection is suspected or confirmed. -
- The patient does not have a THR and the infection is secondary to trauma, septic arthritis or other surgical procedures.
- The patient does not have sufficient bone stock to allow insertion and fixation of the prosthesis
- The patient has neuromuscular disorders that do not allow control of the hip joint. -
- The patient's weight, age or activity level would cause the surgeon to expect early failure of the system.
PERFORMANCE DATA
Performance testing was conducted to verify that the implant performance would be adequate for anticipated in vivo load applications under the temporary conditions of use. The fatigue strength, static strength, wear characteristics and antibiotic release rate were evaluated and found to support the safety and effectiveness of the device.

Dear Dr. Miller:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate 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) that do not require approval of a premarket approval application (PMA). 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. Iisting 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 (PMA). 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 898. In addition. FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must
