Suggestion: The general time is about 7- 15 days, then the initial installation of the prosthesis, and finally the application and assembly of the prosthesis. In developed countries, artificial limbs are now assembled in hospitals after treatment. Due to the late start of prosthesis in China, there was no rehabilitation before the prosthesis was installed in the hospital (even if there was rehabilitation, it was aimed at the rehabilitation of the disease), let alone the prosthesis. Only go to a professional prosthetic company to assemble.
