Sarcoma (see CANCER) of bone, muscle or connective tissues in a limb is another reason for amputation.
The aim is to restore the patient to full mobility with a prosthetic (arti?cial) limb, which requires both a well-?tting PROSTHESIS and a well-healed surgical wound. If this is not possible, the aim is to leave the patient with a limb stump that is still useful for balancing, sitting and transferring. Common types of lower-limb amputation are shown in the illustration. The Symes amputation can be walked upon without requiring a prosthesis. The below-knee amputation preserves normal ?exion of the knee, and virtually normal walking can be achieved with a well-?tting arti?cial limb. Learning to walk is more di?cult following an above-knee amputation, but some highly motivated patients can manage well. After any amputation it is not unusual for the patient to experience the sensation that the limb is still present: this is called a ‘PHANTOM LIMB’ and the sensation may persist for a long time.... amputation
nerve injury Damage or severance of conducting fibres within a nerve as a result of trauma, causing loss of skin sensation and muscle power. (See neuropathy for nerve damage from cause.
other than injury.)
If a peripheral nerve (a nerve outside the brain or spinal cord) is only partially severed, the cut fibres may be able to regenerate. Provided the severed ends are still aligned, new fibres can grow across the cut to rejoin the connection, restoring function. If a nerve is totally severed, the individual fibres cannot regenerate successfully and there is no recovery of function. Nerve tracts within the brain and spinal cord are structurally different from the peripheral nerves, and severed fibres in these tracts do not regenerate. For example, vision cannot be restored if the optic nerves are cut.Microsurgery can sometimes be used to stitch a severed peripheral nerve into place, but recovery is rarely complete.... nerve conduction studies
