ELECTRIC OPTIONS & SOCKET DESIGN FOR PARTIAL HAND PATIENTS
Repository Usage Stats
Recent improvements in prosthetics has allowed for a marked increase in success and functional rehabilitation of the partial hand patient. Manufacturers are designing much smaller and lighter components such as electrodes, switches, batteries, and programmable microprocessors that allow a much smaller and simple prosthesis. In most partial hand cases, this allows the socket to not extend proximal to the wrist for full wrist ROM, simplified socket design, and lighter weight prostheses, all leading to greater acceptance. Improvements are being made with two separate designs for partial hand patients that use an intact thumb to assist with prehension, or a smaller drive unit decreasing space necessary in the hand. Although both designs are progressing, the components are not readily available for most prosthetists fitting a Transmetacarpal/ Transcarpal level amputation. The focus of the paper and presentation is to educate on options currently available and easily used by a majority of the prosthetic field.
