No
This device is a mold used to create a temporary knee prosthesis, which is then used as a temporary treatment for septic processes in the knee. The mold itself does not directly provide therapy.
No
Explanation: The device is a temporary knee prosthesis (cement spacer molds) used during a two-stage procedure for patients with a septic process, not for diagnosing a condition.
No
The device description explicitly states it is a physical mold made of polypropylene intended to be filled with bone cement, and the performance studies focus on mechanical properties, indicating it is a hardware device.
No, 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 (like blood, urine, tissue) to provide information about a person's health. They are used outside of the body.
- Device Function: The SpaceFlex Knee disposable cement spacer molds are used within the body to create a temporary knee prosthesis. They are a surgical implant used during a procedure.
- Intended Use: The intended use is to mold a temporary knee replacement for patients undergoing a two-stage procedure for a septic process. This is a therapeutic and structural function, not a diagnostic one.
- Device Description: The description clearly states they are molds filled with bone cement to create a temporary prosthesis. This is a physical device for implantation.
The information provided about the device's function, intended use, and description all point to it being a surgical implant or a device used in a surgical procedure, not an IVD.

Intended Use / Indications for Use
SpaceFlex Knee disposable cement spacer molds are indicated for use to mold a temporary Total Knee Replacement (TKR) for skeletally mature patients undergoing a two-stage procedure due to a septic process. The molded temporary knee prosthesis is indicated for an implantation period of 180 days or less. Because of inherent mechanical limitations of the device material (G3A Bone Cement), the molded temporary prosthesis is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.

Device Description
G21 SpaceFlex Knee system are disposable cement spacer molds made of polypropylene (PP) intended to be filled with low-viscosity polymethyl methacrylate bone cement directly in the operating room. Once the bone cement has hardened, the SpaceFlex Knee system creates a polymethyl methacrylate based bone cement spacer for patients undergoing a two-stage procedure following a periprosthetic joint infection. The device can be used in either the left or right knee joint. The SpaceFlex Knee molds are singleuse and cannot be re-used or re-sterilized.

Dear Barry Sands:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

IV. DEVICE DESCRIPTION
G21 SpaceFlex Knee system are disposable cement spacer molds made of polypropylene (PP) intended to be filled with low-viscosity polymethyl methacrylate bone cement directly in the operating room. Once the bone cement has hardened, the SpaceFlex Knee system creates a polymethyl methacrylate based bone cement spacer for patients undergoing a two-stage procedure following a periprosthetic joint infection. The device can be used in either the left or right knee joint. The SpaceFlex Knee molds are singleuse and cannot be re-used or re-sterilized.
Intended Use:
SpaceFlex Knee is a mold intended to assist in the creation of a temporary disposable cement spacer for a total knee replacement (TKR) for skeletally mature patients undergoing a two-stage procedure due to a septic process.
Indications for Use:
SpaceFlex Knee disposable cement spacer molds are indicated for use to mold a temporary total knee replacement (TKR) for skeletally mature patients undergoing a two-stage procedure due to a septic process. The molded temporary knee prosthesis is indicated for an implantation period of 180 days or less. Because of inherent mechanical limitations of the device material (G3A Bone Cement), the molded temporary prosthesis is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.
V. COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE PREDICATE DEVICE
Both the subject device and the predicate device are disposable cement spacer molds with two separate molds - femoral and tibial. The subject devices possess identical technical characteristics as the primary predicate. The only difference between subject and predicate devices is a larger dimensional footprint.
The technological features of the SpaceFlex Knee are the same as the primary predicate device.
VI. PERFORMANCE DATA
The mechanical properties of the SpaceFlex knee System 80mm size were tested in accordance with applicable international standards. In all instances the device
5
functioned as intended and all results were satisfactory and met all performance specifications. The testing performed includes:
-
- Dimensional and Visual Characterization
-
- Rupture Test
-
- Fatigue Test
-
- Elution Test
VII. CONCLUSION
The SpaceFlex Knee – 80mm and its primary predicate, G21 SpaceFlex Knee system, have the same intended use and indications for use, technological characteristics and principle of operation. The material differences between the molds in the subject and the predicate device do not raise any significant new risks. Through performance and mechanical testing and material information it has been established that these differences do not present any new issues of safety or effectiveness. The SpaceFlex Knee – 80mm is substantially equivalent to the primary predicate, G21 SpaceFlex Knee System, and additional predicate StageOne Disposable Cement Spacer Molds for Temporary Knee Prosthesis.
