Abstract

A bone fracture fixation system including reference pins inserted into bone fragments of a patient in a first configuration and an image capture device configured to capture an image of the reference pins, and the bone fragments. The system includes a processor configured to receive and pre-process the captured image data. The processor pre-processes the image data by virtually re-positioning the reference pins in the first configuration into a second configuration, wherein the re-positioning virtually re-positions the bone fragments into normal alignment; and virtually generating a support device. The system includes a point-of-care production apparatus that produces a three-dimensional model of the virtually generated support device in a form that can be applied to the patient. The three-dimensional support device generated by the point-of-care production apparatus is configured to receive the reference pins in the first configuration; and simultaneously re-positions and fixes the bone fragments into normal alignment.

Claims14

Dependent claims

A digitally-guided reduction and external fixation system for reducing and fixing a bone fracture comprising:

one or more reference pins configured to be inserted into one or more bone fragments of a patient in a first configuration;
an image capture device configured to capture an image of the one or more reference pins in the first configuration, and the one or more bone fragments,
a virtual reduction and fixation device comprising a processor configured to execute instructions to:
receive the captured image data of the one or more reference pins in the first configuration, and the one or more bone fragments;
pre-process the image data by virtually re-positioning the one or more reference pins in the first configuration into a second configuration, wherein the re-positioning of the one or more reference pins into the second configuration virtually re-positions the one or more bone fragments into normal alignment;
virtually generate a support device, wherein the support device comprises one or more apertures configured to receive the one or more reference pins in the second configuration and the support device is configured to simultaneously achieve reduction and long-term fixation by repositioning and fixing the one or more bone fragments into normal alignment;
and
send a description of the virtually generated support device to a point-of-care production apparatus.
