By cupping, or containing this bone inside the socket, the socket tends not to shift laterally (outside) when weight is put on it, making walking more efficient. This style of socket can have a very intimate fit and may take some time to get used to in order for it to become more comfortable.

  • Myodesis procedure: Performed during an amputation by sewing the opposing bundles of cut muscle tissue to small holes drilled into the end of the bone of the residual limb. Adds to the performance of the muscles since it is a more secure attachment for the muscles to act on and also helps to prevent future atrophy.
  • Myoelectric prosthesis: This prosthesis which uses electrodes mounted within the socket to receive signals from muscle contraction to control a motor in the terminal device, wrist rotator, or elbow.
  • Myoplasty: Muscles anchored to opposing muscles.
