Because prosthetic devices are custom fabricated, and have many different components, the process to fit takes time. Once your limb has healed, you will be molded for a test socket, which is the initial device you will be learning to walk on. In about a week, given your availability, you will be able to come in for a fitting. You may have to come back several times, depending on complications, availability, and tolerance to the device.
Once it’s determined that the fit and alignment of the device are appropriate, the device will be “finished.” This process takes about a week. The total process time for the fit of a final prosthesis varies by individual, but an average time frame to consider is about a month.
