About Analyze My Hand
The team, stated up front
A single independent team runs this site — the same one that develops JointLens, the umbrella product for everything we build around patient-side imaging. We have no hospital affiliation, no commercial sponsor and no referral arrangement with any hand surgeon. The work is ours, the mistakes are ours, and this page exists so that both have an address.
Hand and finger imaging we can open
Most people arrive with radiographs, which remain the workhorse for the hand; CT and MRI open here too, from single DICOM files or a zipped archive. The viewer runs on your device, so you can enlarge a single digit and adjust contrast before deciding what is worth explaining. The AI description then walks through the rendered images in everyday language: cortical breaks and angulation through the phalanges and metacarpals, the alignment of joint surfaces after a dislocation, the ulnar collateral ligament of the thumb at the metacarpophalangeal joint, flexor tendons and the annular pulleys along the finger, joint space narrowing and marginal spurs at the distal and proximal interphalangeal joints, and soft tissue swelling that points to where the injury actually is.
The findings it misses
Many of the hand injuries that matter most leave no radiographic trace. A ruptured extensor slip, a trigger finger that catches, a pulley torn while climbing, or a thumb ligament that has displaced above the adductor aponeurosis are diagnosed by how the finger behaves under the hands of a clinician — an unremarkable image is not reassurance. Tiny avulsion fragments at a joint margin and non-displaced fractures are easy to miss entirely at typical viewing scales, and rotational deformity, which changes the entire treatment plan, is judged with your fingers flexed, not on a flat picture. Nobody medically qualified reviews the text before it appears.
Keeping this safe to use
Analysis is gated behind a consent step describing the tool as educational and explicitly not diagnostic; it must be accepted every time it applies. That warning is reprinted on every result, and our Medical Disclaimer lays out the errors these models make with images. A finger that is crooked, cannot straighten, has gone pale or numb, or was injured by a bite or a high-pressure tool needs to be seen immediately.
Files stay on your device
Nothing you open is uploaded. Your archive is expanded and your images are drawn by code executing in the browser, so the original study and its identifying header never reach our systems. An analysis request carries the rendered frames you selected and the context you typed, our server forwards them to the model providers, and no copy is kept once the answer returns. There is no imaging archive on our side — by design, not by policy — as described in the Privacy Policy.
