CHAPTER IX - Hip-Joint Amputations
REQUIREMENT. - An amputation at the hip joint or close to the body requires an artificial leg identical in construction to either of the patterns heretofore described for thigh stumps, with the exception that some modifications are introduced in the knee and the means of suspension is more complex.

MUSCLE STUMP. - Cuts I-1 and I-2 illustrate front and side views of amputations at the coxo-femoral or hip articulation, leaving a stump composed entirely of muscle tissue. A muscle stump is capable of performing some functions, although limited, in the management of an artificial leg, and may be considered as more desirable than no stump at all. Cuts I-3 and I-4 represent a hip-joint amputation in which there is no protruding stump by which the artificial leg can be directed. The amputated surface at the base of the pelvis is capable of bearing pressure.

LEG APPLIED. - Cuts I-5 and I-6 show a leg applied to hip-joint amputation having muscle stump. The means by which it is suspended consist of a waist belt, shoulder strap, over each shoulder, flexion and extension elastic straps, a metal hip joint substituting the natural hip articulation, and an attachment by which the knee can be locked and made immovable, or capable of having but limited motion, these features have all been explained in the preceding chapter.

The hip joint is important as it keeps the artificial leg directly under the wearer. The waist belt with its elastic straps front and rear assists in flexing and extending the leg at the hip. The leg is held firmly to the body when standing or walking; it should be especially noted, that it is not advisable to allow any knee motion while the wearer is learning to control the leg. During this period the knee motion is only for sitting conveniences.

Cut I-7 shows a leg with pelvic socket suitable for a hip-joint amputation where there is no protruding stump to control the artificial hip motion.

Cuts I-8, I-9, I-10, I-11, I-12, show the leg applied and the wearer in many positions. The pelvic socket takes in a part of the pelvis and holds the artificial leg firmly to its place no matter what positions the wearer may assume. The hip joint is controlled by throwing the body forward or backward of the center of gravity of the leg.

Artificial legs for hip-joint amputations support the amputated side in a very comfortable and natural manner. The leg, having little or no stump to control it, is thrown forward by means of a side motion of the body. Persons with reasonable perseverance soon learn to control the legs under these conditions in an advantageous way.
