Intended Use
Wright's PROPHECY® Preoperative Navigation Alignment Guides are intended to be used as patient-specific surgical instrumentation to assist in the positioning of total ankle replacement components intra-operatively and in quiding the marking of bone before cutting. The PROPHECY® Preoperative Navigation Alignment Guides are intended for use with Wright's INBONE® and INFINITY™ Total Ankle Systems and their cleared indications for use, provided that anatomic landmarks necessary for alignment and positioning of the implant are identifiable on patient imaging scans. The PROPHECY® Preoperative Navigation Alignment Guides are intended for single use only.
Device Description
PROPHECY® Preoperative Navigation Alignment Guides are patient-specific quides created to fit the contours of the patient's distal tibial and proximal talar anatomy. The quides are designed and manufactured from patient imaging data (CT) and are made from biocompatible nylon. The PROPHECY® Guides serve as an alternative to traditional alignment instrumentation used with Wright's INBONE® and INFINITY™ Total Ankle Systems, and thereby reduce the overall number of surgical steps reguired during total ankle arthroplasty. The quides serve to position and align the implants comparable to that attainable with traditional instrumentation.
More Information

No
The description focuses on patient-specific guides created from CT data, serving as an alternative to traditional instrumentation. There is no mention of AI or ML in the intended use, device description, or performance studies. The process described is based on anatomical contours from imaging, not on learning from data.

No.
The device is a surgical guide used to assist in the positioning of total ankle replacement components and to guide the marking of bone before cutting, rather than providing direct therapy or treatment.

No
The device is described as patient-specific surgical instrumentation intended to assist in the positioning of total ankle replacement components and guiding bone marking, serving as an alternative to traditional alignment instrumentation. It does not generate a diagnosis or provide diagnostic information.

No

The device description explicitly states the guides are "designed and manufactured from patient imaging data (CT) and are made from biocompatible nylon," indicating a physical, manufactured component.

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.
  • Device Function: The Wright's PROPHECY® Preoperative Navigation Alignment Guides are surgical instruments used during a surgical procedure (total ankle replacement). They are patient-specific guides designed to assist the surgeon in positioning and aligning implants and marking bone for cutting.
  • No Sample Testing: The device does not involve testing any samples taken from the patient's body. It is a physical tool used directly on the patient's anatomy during surgery.

Therefore, based on the provided information, the Wright's PROPHECY® Preoperative Navigation Alignment Guides fall under the category of surgical instrumentation, not in vitro diagnostics.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The following evaluations were conducted to support the safety and efficacy of the PROPHECY® INFINITY™ quides:

  • Guide design repeatability across design engineers
  • Guide placement repeatability
  • Cadaver evaluation by end users analyzing placement location and orientation
  • Software validation

These evaluations concluded the subject alignment quides are substantially equivalent to the predicates.

§ 888.3110 Ankle joint metal/polymer semi-constrained cemented prosthesis.

(a)
Identification. An ankle joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace an ankle joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces and has no linkage across-the-joint. This generic type of device includes prostheses that have a talar resurfacing component made of alloys, such as cobalt-chromium-molybdenum, and a tibial resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027).(b)
Classification. Class II.

C. Substantial Equivalence Information

The main difference between the subject and predicate PROPHECY® guides is the addition of use with the INFINITY™ Total Ankle System. The design features and materials of the subject devices are substantially equivalent to those of the predicates. The fundamental scientific technology has not changed relative to the predicate devices. The safety and efficacy of the PROPHECY® quides are adequately supported by the substantial equivalence information, materials information, and analysis data provided within this premarket notification.
