tuberosity): The Ischial Containment socket cups the Ischial
bone on the inside and back as well as the bottom to accomplish two things:
1) 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 comfortable.

that protrudes from the back of the pelvis (the "butt bone") that may get
sore when sitting on a hard surface for extended periods of time.

This is a technology used in upper-extremity prosthetics. The prosthesis
contains electrodes which are used to control the prosthesis via muscle
contractions which in turn control a motor in the terminal device, wrist
rotator or elbow . An attached battery pack provides the power system
which translates the muscle contractions into movements of the prosthesis.

to end of bone.
myoplasty: muscles anchored
to opposing muscles.
N (
back

of a nerve left after amputation, which continues to grow in a cauliflower
shape. Neuromas can be troublesome, especially when they are in places
where they are subject to pressure from the prosthesis socket.
Normal Shape/Normal Alignment (NSNA)-
also know as a narrow ML socket: First described by Ivan Long,
this socket more closely approximates the shape of the musculature of a
residual limb, when compared to a quad socket. The sides,
or medial/lateral measurement is tightened down to squeeze the residual
limb, with most of the squeezing taking place on the outside or lateral
side. This helps control the rotation of the socket by putting pressure
along the fleshy area of the leg that can handle some side to side pressure.
