  9. Custom cutting and drilling guides for intra-op use are a specialized medical product and thus extra care needs to be taken. I am a big advocate of open source and free software, but in this case I think you should use FDA approved software such as Mimics from Materialise. Unfortunately, it is pricy. Alternatively, you can contact a company that designs custom surgical guides and is aware of the evolving FDA guidance with respect to 3D printed medical devices. The image below is a pic I took at RSNA 2016 of a fibular cutting guide that was used in a mandibular reconstruction. It was made by the 3D systems subsidiary Medical Modeling. Hope this helps.

    This high quality .FORM file of the lumbar spine is confirmed 3D printable on Formlabs printers. It was taken from a patient with a chronic L2 lumbar spine compression fracture. The abnormal L2 vertebral body has caused severe degenerative change at the L2-3 level, with obliteration of the L2-3 intervertebral disk and severe osteophyte formation. The fracture and collapse of the L2-3 disk causes subluxation of the facet joints at this level, and narrowing of the L2 neural foramen. It is clearly illustrated how degenerative, arthritic change can result in nerve pinching at the neural foramen. This model can be used for scientific and medical education, and shows what compression fractures and degenerative spine disease look like. Also, the model is useful for teaching spinal interventions, such as lumbar punctures, epidural steroid injections, selective nerve root blocks, vertebroplasty, and kyphoplasty. The file is in .FORM file format for Formlabs printers, 53.9 MB 221181 vertices, 442558 polygons Confirmed printable on Formlabs Form 2 with white resin.

  12. Agree with Mike. Be careful about using mm for imports. If your model turns out to be the size of a house, chances are you used the wrong units!
  13. MRI is not that easy a modality to work with because scans from different facilities and scanners can have wildly different intensity values due to variances in pulse sequence, magnet strength, etc. Manual segmentation can be done with any number of sequences, but automation will be hugely challenging.
  14. Agree with Terrie's general strategy. You can export the bone and implant as separate STL files and join them in a mesh-editing software program. I don't use Meshlab, but I know you can do this with MeshMixer and Blender using boolean union. To make things interesting I know if Blender you can assign each object to be a different "material" so when you do the join they will appear differently. If you are planning a multimaterial print this can be useful. In this blog article I talk about printing a spine with orthopedic hardware. I used different materials for the render, but for the 3D print decided to go with only one material. This just shows what you can do though. Dr. Mike
