Musculoskeletal Flashcards
forequarter (scapulothoracic) amputation
surgical removal of the upper extremity including the shoulder girdle
shoulder disarticulation
surgical removal of the upper extremity through the shoulder
transhumeral amputation
surgical removal of the upper extremity proximal to the elbow joint
elbow disarticulation
surgical removal of the lower arm and hand through the elbow joint
transradial amputation
surgical removal of the upper extremity distal to the elbow joint
wrist disarticulations
surgical removal of the hand through the wrist joint
partial hand amputation
surgical removal of a portion of the hand and/or digits at either the transcarpal, transmetacarpal, or transphalangeal level
digital amputation
surgical removal of a digit at either the metacarpophalangeal, proximal interphalangeal, or distal interphalangeal level
hemicorporectomy amputation
surgical removal of the pelvis and both lower extremities
hemipelvectomy amputation
surgical removal of one half of the pelvis and the lower extremity
hip disarticulation
surgical removal of the lower extremity from the pelvis
transfemoral amputation
surgical removal of the lower extremity above the knee joint
knee disarticulation
surgical removal of the lower extremity through the knee joint
transtibial amputation
surgical removal of the lower extremity below the knee joint
Symeās amputation
surgical removal of the foot at the ankle joint with the removal of the malleoli
transverse tarsal (Chopartās) amputation
amputation through the talonavicular and calcaneocuboid joints. The ambulation preserves the plantar flexors, but sacrifices the dorsiflexors, often resulting in an equinus contracture
tarsometatarsal (Lisfranc) amputation
surgical removal of the metatarsals. The amputation preserves the dorsiflexors and the plantar flexors.
acquired amputation
refers to the surgical removal of a limb due to disease, trauma, or infection. This can be further defined as traumatic and non-traumatic amputation.
dysvascular
refers to the disease of blood vessels, including peripheral vascular disease, peripheral arterial disease, and complications related to diabetes
endoskeletal shank
this type of shank consists of a rigid pylon covered with a material designed to simulate the contour and color of the contralateral limb
exoskeletal shank
this type of shank consists of a rigid external frame covered with a thin layer of tinted plastic to match the skin color distally
extension assist
a mechanism that assists the knee joint into extension during the swing phase of gait
myodesis
the anchoring of muscle tissue or tendon to bone using sutures that are passed through small holes drilled in the bone. This procedure is performed as part of the amputation closure process
myoelectric prosthesis
a device using electromyography signals to control movements of the prosthesis with surface electrodes or implantable wires
myoplasty
suturing amputated muscle flaps together over the end of a bone following an amputation
non-traumatic amputation
an amputation that is not the result of direct injury. Vascular disease and infection are types of non-traumatic amputations
osseointegration (endoprosthesis)
the process of implanting a prosthetic device directly into the residual limb of a person with limb loss. This process negates the need for a socket component
pistoning
the translation of the prosthetic limb from the residual limb. It is the result of inadequate suspension and can result in distal residual limb skin issues
polycentric knee
refers to a knee joint that has multiple axes of rotation that allows for a more natural gait cycle when compared to a single axis knee
pylon
term used to describe a pipe-like structure used to connect the socket of the prosthesis to the foot/ankle components. The pylon assists with weight bearing and shock absorption
rotationplasty
operation where a portion of the limb is removed while the remaining limb below is rotated and reattached. This procedure is often performed as a treatment for distal femoral osteosarcoma
shrinker
elastic sleeve that is placed over the end of the residual limb to control edema and encourage limb shaping
stance control (safety)
weight-activated mechanism that maintains knee extension during weight bearing, even if the knee joint is not fully extended. If the knee is flexed greater than what the control mechanism is designed for, the mechanism will not engage
suspension
the term used to describe how the prosthetic socket is attached to the residual limb. Common types of suspension include vacuum, shuttle lock, suction, waist belt, and harness.
traumatic amputation
an amputation performed secondary to a direct injury. A car accident or gunshot wound are potential examples of injuries resulting in traumatic amputation.
heel strike
Standard Terminology (gait)
the instant that the heel touches the ground to begin stance phase
foot flat
Standard Terminology (gait)
point in which the entire foot makes contact with the ground and should occur directly after heel strike
midstance
Standard Terminology (gait)
the point during the stance phase when the entire body weight is directly over the stance limb
heel off
Standard Terminology (gait)
point in which the heel of the stance limb leaves the ground
toe off
Standard Terminology (gait)
point in which only the toe of the stance limb remains on the ground
acceleration
Standard Terminology (gait)
begins when toe off is complete and the reference limb swings until positioned directly under the body
midswing
Standard Terminology (gait)
point when the swing limb is directly under the body
deceleration
Standard Terminology (gait)
begins directly after midswing, as the swing limb begins to extend, and ends just prior to heel strike
initial contact
RLA Terminology (gait)
beginning of the stance phase that occurs when the foot touches the ground
