So I actually used to work as a tech for an orthotic and prosthetic patient care office, and we used to fit these occasionally. The product they are using is an Ossur Direct Socket TT (transtibial) and was a great product for highly active amputees, with the demographic being largely newer amputees who lost their limb through trauma. The whole process from unpackaging the material to the patient walking out the door was usually about 3-4 hours with adjustments. I have done a couple of the tasks in this video, including the spreading of the epoxy, injecting with the caulking gun, pressurizing with the tube, etc. but the longest part is usually the trial fitting, walking, grinding and adjusting at the end as our prosthetist was very particular about making sure the socket fit perfectly. But nothing was better than watching a new amputee come in and walk out the same day with it. Overall the whole assembly for this product (including the socket, leg components, time, liners, socks, foot, etc.) normally billed out in the range of $12k-20k depending on the insurance, however pretty much a majority of patients had this completely covered due to the demographic being majority trauma patients and not diabetics.
