CustomSurg OrthoPlanner is a software system designed to help surgeons carry out pre-operative planning for surgical procedures, based on their patients' imaging studies.
The software imports diagnostic imaging studies such as x-rays and CT images. In parallel, there is a database of digital representations related to implant materials supplied by their producing companies.
The software can process an imported 3D model of the patient's CT scan to digitally perform the surgical planning. Experience in usage and a clinical assessment are necessary for proper use of the software.
CustomSurg OrthoPlanner is to be used in conjunction with the planned device's instructions for use, the patient's clinical history, symptoms, and other pre-procedural evaluations by a surgeon who is responsible for making all final patient management decisions.
It is not intended to replace the planned device's instructions for use.
CustomSurg OrthoPlanner is a medical software that supports surgeons in orthopedic pre-surgical planning in the musculoskeletal system in a healthcare environment.
It is a web-based application that allows surgeons to upload the required data, provide details of planning the surgery and receive 3D visualization of the submitted plan. To properly use the device, clinical judgment and experience is mandatory and it shall be used in conjunction with diagnostic tools. CustomSurg OrthoPlanner does not perform any diagnostic evaluations and will not have intra-operative functionality.
The provided FDA 510(k) clearance letter for CustomSurg OrthoPlanner does not contain specific details about the acceptance criteria or the study that proves the device meets those criteria. The letter and the 510(k) summary explicitly state:
"Results from internal verification and validation testing performed in accordance with CustomSurg's design control processes confirm that the CustomSurg OrthoPlanner product specifications have been met. Acceptance criteria were achieved for all tests. Supporting documentation is included in this 510(k) Premarket Notification and supports the claims of substantial equivalence to the predicate device."
And then: "Not Applicable" for clinical tests.
This means the detailed study results, acceptance criteria, sample sizes, ground truth establishment, and expert qualifications are not provided in the given document. The FDA clearance is based on the claim of substantial equivalence to a predicate device (PeekMed) and internal verification and validation, rather than a separate clinical study whose details are presented in this public letter.
Therefore, I cannot extract the requested information from the provided text.

Device Description Summary
21 CFR 807.92(a)(4)
CustomSurg OrthoPlanner is a medical software that supports surgeons in orthopedic pre-surgical planning in the musculoskeletal system in a healthcare environment.
It is a web-based application that allows surgeons to upload the required data, provide details of planning the surgery and receive 3D visualization of the submitted plan. To properly use the device, clinical judgment and experience is mandatory and it shall be used in conjunction with diagnostic tools. CustomSurg OrthoPlanner does not perform any diagnostic evaluations and will not have intra-operative functionality.
Intended Use/Indications for Use
21 CFR 807.92(a)(5)
CustomSurg OrthoPlanner is a software system designed to help surgeons carry out pre-operative planning for surgical procedures, based on their patients' imaging studies.
The software imports diagnostic imaging studies such as x-rays and CT images. In parallel, there is a database of digital representations related to implant materials supplied by their producing companies.
The software can process an imported 3D model of the patient's CT scan to digitally perform the surgical planning. Experience in usage and a clinical assessment are necessary for proper use of the software.
CustomSurg OrthoPlanner is to be used in conjunction with the planned device's instructions for use, the patient's clinical history, symptoms, and other pre-procedural evaluations by a surgeon who is responsible for making all final patient management decisions.
It is not intended to replace the planned device's instructions for use.
Indications for Use Comparison
21 CFR 807.92(a)(5)
CustomSurg believes the CustomSurg OrthoPlanner is substantially equivalent to the predicate device based on the information summarized below.
Page 6
Indications for Use Comparison
The differences between the indications for use of PeekMed and CustomSurg OrthoPlanner are:
- PeekMed supports importing medical images directly from PACS while CustomSurg OrthoPlanner does not have a direct PACS interface.
- PeekMed supports the use of MRI medical images while CustomSurg OrthoPlanner does not.
The differences specified above do not constitute a new intended purpose because they only regard clinically irrelevant features, the image import feature. The intended purpose of both the device and its predicate is to serve as a support tool for surgery planning. It can be concluded that the differences do not raise new questions of safety and effectiveness of the device compared to the predicate.
Technological Comparison
21 CFR 807.92(a)(6)
Technological Comparison
The device and its predicate are both medical software that allow surgeons to perform orthopedic pre-surgical planning in the musculoskeletal system in a healthcare environment, therefore share the same intended use, same intended user and a similar intended population. To properly use both devices, clinical judgment and experience is mandatory. Both devices have similar workflows, use requirements (e.g. internet connection, output validation), planning features (e.g., model representation, digital representation of prosthetic material). Neither the device nor its predicate use artificial intelligence (AI).
All technological characteristics of the CustomSurg OrthoPlanner have been substantiated by the predicate device. Any technological differences have been assessed and determined to not raise new questions of safety and effectiveness. As such, the CustomSurg OrthoPlanner and PeekMed have been determined to be substantially equivalent.
Non-Clinical and/or Clinical Tests Summary & Conclusions
21 CFR 807.92(b)
Results from internal verification and validation testing performed in accordance with CustomSurg's design control processes confirm that the CustomSurg OrthoPlanner product specifications have been met. Acceptance criteria were achieved for all tests. Supporting documentation is included in this 510(k) Premarket Notification and supports the claims of substantial equivalence to the predicate device.
A risk analysis in accordance with ISO 14971 was completed as part of the software design and development effort.
Not Applicable
CustomSurg OrthoPlanner, as designed and developed by CustomSurg AG, is determined to be substantially equivalent to the predicate device. Differences between the two devices do not raise new questions about the safety and effectiveness of CustomSurg OrthoPlanner.
