🦻 The three bones that transmit sound in the human ear the malleus, incus and stapes are the smallest bones in the body. Combined they fit on a fingernail. When they fail, conventional medicine had no replacement option.
A South African surgeon used CT scans to model a patient's exact ossicular geometry, printed titanium replicas at microscale precision, and implanted them. The patient's hearing was restored.
This is the convergence of medical imaging, additive manufacturing, and microsurgery producing outcomes that were categorically impossible a decade ago.
Every organ that fails will eventually have a printable answer. The ear bones just became the proof of concept.
