The PRECICE System is indicated for limb lengthening, open and closed fracture fixation, pseudoarthrosis, mal-unions, non-unions, or bone transport of long bones.
The PRECICE System is composed of the PRECICE Nail (supplied sterile), locking screws, end cap, surgical instruments and an external remote controller (ERC). The Nail is available in various diameters, lengths and screwhole configurations to accommodate a variety of patient anatomies. The locking screws are also available in a variety of diameters and lengths. The PRECICE Nail and end cap is supplied sterile by gamma radiation while the locking screws and reusable instruments are supplied non-sterilized prior to use. The Nail contains an enclosed rare earth magnet, telescoping lead screw/nut assembly, and planetary gearing. The Nail is offered in pre-distracted and non-pre-distracted models. Pre-distracted models are supplied pre-distracted by 10 mm (femur and tibia models), 15 mm and 20 mm (humeral model), to allow for compression fracture reduction techniques
The provided text is related to a 510(k) premarket notification for the "PRECICE System," an intramedullary fixation rod. This submission is for a medical device cleared through the FDA's 510(k) pathway, which establishes substantial equivalence to a predicate device rather than proving clinical effectiveness in the same way clinical trials for drugs or novel devices might.
Therefore, the input document does not contain the information requested in points 1-9 because the regulatory pathway for this device (510(k) substantial equivalence) does not typically involve the types of studies, acceptance criteria, or performance metrics (like sensitivity, specificity, AUC) associated with AI/ML solutions or devices requiring a de novo or PMA pathway that directly measure clinical outcomes or diagnostic accuracy against a ground truth in a clinical setting.
Instead, the document details a comparison of the subject device (PRECICE System) to predicate devices (e.g., PRECICE UNYTE System, PRECICE Intramedullary Limb Lengthening System) based on:
- Indications for Use: The subject device has similar indications for limb lengthening, open and closed fracture fixation, pseudoarthrosis, mal-unions, non-unions, or bone transport of long bones. The submission explicitly states its intent to align indications with the predicate devices.
- Technological Characteristics & Principles of Operation: Both the subject and predicate devices utilize the same design for the intramedullary nail, are inserted similarly, secured with locking screws, and adjusted non-invasively by an External Remote Controller (ERC).
- Testing: The document states, "There are no design, technological or performance changes to the PRECICE Nail being made as a result of this submission as the PRECICE System is identical to the PRECICE UNYTE System, therefore all testing that was performed on the predicate PRECICE UNYTE Nail and PRECICE Systems previously cleared, are applicable." This means the substantial equivalence is based on prior testing of the predicate devices.
In summary, none of the requested information (acceptance criteria, specific study design details, expert involvement for ground truth, sample sizes for training/test sets, or MRMC studies) can be extracted from this document because it describes a 510(k) submission based on substantial equivalence rather than a clinical performance study with specific metrics as would be required for an AI/ML device.
§ 888.3020 Intramedullary fixation rod.
(a)
Identification. An intramedullary fixation rod is a device intended to be implanted that consists of a rod made of alloys such as cobalt-chromium-molybdenum and stainless steel. It is inserted into the medullary (bone marrow) canal of long bones for the fixation of fractures.(b)
Classification. Class II.
