No
The device description and performance studies focus on the physical properties and function of a mold for creating a temporary hip prosthesis, with no mention of AI or ML technologies.
No.
The device itself is a mold used to create a temporary hip prosthesis, not the therapeutic prosthesis itself. The prosthesis, once molded, is intended to be used in conjunction with systemic antimicrobial antibiotic therapy to address a septic process, which is the therapeutic aspect.
No
The device is a medical mold used to create a temporary hemi-hip replacement, not to diagnose a condition or disease. It is used as part of a treatment procedure (two-stage revision for septic processes).
No
The device description explicitly states it is made of silicone with a stainless steel reinforcement stem, head insert, and neck length adapter, indicating it is a physical medical 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. They are used to provide information for diagnosis, monitoring, or screening.
- Device Function: The StageOne™ Select Hip Cement Spacer Molds are used to create a temporary physical implant (a hemi-hip prosthesis) that is surgically placed inside the patient's body. It is a physical device used for structural support and to deliver antibiotics locally.
- Lack of Biological Sample Analysis: The description does not mention the device being used to analyze any biological samples from the patient. Its function is entirely related to the surgical creation and implantation of a temporary prosthesis.
Therefore, the StageOne™ Select Hip Cement Spacer Molds fall under the category of a surgical implant or device, not an in vitro diagnostic.
N/A
Intended Use / Indications for Use
StageOne™ Select Hip Cement Spacer Molds with stainless steel reinforcement stems, adapters and inserts are indicated for use to mold a temporary hemi-hip replacement for skeletally mature patients undergoing a two-stage revision procedure due to a septic process. The temporary prosthesis is molded using Refobacin Bone Cement R, assembled and inserted into the femoral medullary cavity following removal of the existing femoral and acetabular replacement implants and debridement. The device is intended for use in conjunction with systemic antimicrobial antibiotic therapy (standard treatment approach to an infection).
The hemi-hip prosthesis made from the StageOne™ Select Cement Spacer Molds is not intended for use more than 180 days, at which time it must be explanted and permanent devices implanted or another appropriate treatment performed (e.g. resection arthroplasty, fusion, etc.).
Due to the inherent mechanical limitations of the hemi-hip prosthesis material (Refobacin Bone Cement R), the temporary hemi-hip prosthesis is only indicated for patients who will consistently use traditional mobility assist devices (e.g. crutches, walkers) throughout the implant period.

Device Description
The StageOne™ Select Hip Cement Spacer Molds are sterile, single use medical devices made of silicone with a stainless steel reinforcement stem, head insert and neck length adapter. The device is used to create a temporary hip implant component made from antibiotic bone cement, Refobacin® Bone Cement R by injecting with a dispenser/gun into the mold. After removal of the initial femoral and acetabular implants, the prepared cement spacers are assembled using the neck length adapter and placed into the femoral joint space using Refobacin® Bone Cement R as the first stage of a two-stage revision surgical procedure. The temporary hemi-hip prosthesis remains in place (180 days or less) until the second stage of the two-stage revision procedure is performed to implant a conventional hip joint prosthesis.
