Validation studies (3)

Standalone

sample size not stated

endpoints: Users were successfully able to use the HipCheck as intended to determine the alpha angle and utilize the virtual measurement and visualization tools.

Standalone

n=745 images · 6 site(s)

endpoints: Automatically detects the presence or absence of a hip; Finds the region of the image that contains the femur with high accuracy

Standalone

sample size not stated

endpoints: segmentation accuracy; reliability of segmentation; reliability of the HipMap FAI Analysis by comparing clinical measurement outputs

Reported performance (0 observations)

FDA source did not state a quantitative performance metric — non-reporting is itself the signal.

Each value carries its own analysis unit and task — never compare or pool across devices. Source: 510(k) summary PDF.

Recall and MAUDE counts are product-code-level (reports aren't reliably attributable to one device); a recall is shown as device-attributed only when the recall record itself lists this clearance number. Signals are descriptive observables with sources — never a judgment that the device is unsafe or drifting. Snapshot 2026-08-26.

Reimbursement — how devices like this got paid

Not yet tracked — no payment pathway indexed for this clearance (the reimbursement corpus is a growing seed set).

Applicable FDA guidance — what the submission is measured against

FDA guidance documents and guiding principles applicable to 510(k) AI/ML devices in the Radiology panel. A curated reference index, not legal or regulatory advice — each item states its own status, and a draft is never binding.

Applicability is derived from the device's FDA advisory panel and pathway — cross-cutting guidances apply to every AI/ML device; panel-specific ones are flagged. Titles, dates, and links verified against fda.gov as of July 2026.
