Post-op amputation dressing- ridgid immediate limits residual limb edema does not allow for daily wound inspection and dressing changes
post-op amputation dressing - soft inexpensive elastic wrap and elastic shrinker poor control of edema
post-op temp prosthesis can be fitted as soon as the wound is healed shrinks residual limb more effectively allows for early ambulation normally used for younger candidates whose amputation was not a result of vascular disease
What are the components of a prosthetic socket and terminal device
prosthetic socket custom molded to the residual limb with total contact and full load distribution with the goals of assisting circulation and providing maximum sensory feedback
prosthetic sock provide soft interface between the residual limb and socket used to accommodate for changing residual limb volume should not exceed 15 ply thickness for proper fit and weight bearing of the socket
prosthetic terminal device functions to provide an interface between the prosthesis and the external environment for LE prosthesis it is the foot for UE prosthesis it is the hook/hand
partial foot prostheses needed more for transmetatarsal amputation
what does a Below-Knee prostheses consist of foot-ankle assembly, shank, socket, and suspension
foot ankle assembly for BKA absorbs shock at heel strike, PF in early stance
What are some non-articulated feet SACH foot (Solid Ankle Cushion Heel) SAFE foot (Stationary attachment flexible endoskeleton) Seattle foot Fex-foot (Springlite foot)
SACH foot MOST COMMON FOOT-non articulating, variety of cosmetic colors to match skin, durable, easy to use, rollover at terminal stance -cushion heel permits PF in early stance and allows for a small amount of mediolateral and transverse motion -can make many si
SAFE foot -a version of SACH foot -allows for walking on moderately uneven terrain because of the greater range of mediolateral motion permitted in the rear-foot -active individuals -disadvantage: heavier than SACH foot
Seattle foot -slightly flexible plastic keel bends at heel contact -keel stores energy and recoils in latte stance releasing energy for springy termination to stance -disadvantage: heavier than SACH foot
Flex-Foot -includes a long band of carbon fiber material, which extends from the toe to the proximal shank and to the posterior heel section -the long bands acts as a leaf spring, enabling the foot to store energy in early and mid stance and the release it in late
What are some articulated feet single-axis foot multi-axis foot
single-axis foot MOST COMMON articulating foot that permits PF and DF, as well as toe break action -does not allow mediolateral or transverse motion -may be prescribed for individuals with bilateral transfemoral amputations -disadvantage: permits PF and DF only, limite
multi-axis foot has components that move slightly in all planes to aid the patient in walking on uneven terrain and slopes -disadvantage: heavier and less durable than single-axis or non-articulated feet
Shank -provides leg length and shape -transmits weight from socket to foot -exoskeletal-usually made of wood with a plastic laminate finish that can be colored to match the skin-very durable -endoskeletal-central aluminum or rigid plastic pylon covered with
Socket patellar-tendon bearing (PTB) -total contact socket that allows for maximum distribution of the load and assistance in venous blood circulation -provides tactile feedback
Socket Reliefs -reliefs are concavitites over PRESSURE SENSITIVE AREAs of the transtibial residual limb such a she anterior tibia, anterior tibial crest, fibular head and neck, and peroneal (fibular) nerve
Socket built-ups are convexities over PRESSURE TOLERANT AREAs such as patellar tendon, medial tibial plateau, tibial and fibular shafts and distal end of tibia
Suspension used to hold the socket onto the residual limb when non-weight bearing is occuring ex: swing phase
What types of suspension are there -supracondylar suspension (SC) -Supracondylar/suprapatellar suspension (SC/SP) -Thigh corset suspension
Supracondylar suspension (SC) -medial and lateral walls of the socket extend up and cover the femoral condyles -a removable medial wedge is placed between the socket and the medial epicondyle -more cosmetic with no buckles and increases mediolateral stability
Supracodylar/Suprapatellar suspension (SC/SP) -similar to the SC with the addition of an anterior wall, which terminates above the patella -used for SHORT RESIDUAL LIMBS -may interfere with kneeling and is very visible when sitting
Thigh corset suspension -has metal hinges attached distally to the medial and lateral aspects of the socket and proximally to a leather corset that may be as high as the ischial tuberosity -it provides a larger area for weight bearing -prescribed for individuals with SENSITIVE
what does an Above Knee prostheses (AK) consist of -consist of foot-ankle assemble, shank, knee unit, socket, and suspension device
what type of knee unit AK prostheses are there -enables to bend the knee when sitting and during ambulation -single axis -polycentric system (multiaxial) -friction mechanism -hydraulic knee units
Single-axis knee unit permits knee motion around a fixed axis -knee flexion is needed during late stance and swing phase -knee locks in extension for heel strike and foot flat
Polycentric system knee unit -allows for adjustment to the center of knee rotation -more stable -less used because of the greater complexity and other means to stabilize knee
Friction mechanism knee unit -change the knee swing by modifying the speed of knee motion, providing resistance to pendulum motion at the knee -the most popular is the constant friction unit which has a clamp that can vary the friction easily -usually for older individuals who do n
Hydraulic knee units -fluid controlled/pneumatic knee units (air controlled) -adjust to the individual's walking speed and vary the resistance accordingly -for younger more active individuals -heavier, more complicated, require increased maintenance and have higher costs t
extension aids -many knee units have a mechanism to assist knee extension during the latter part of swing phase -elastic webbing located in front of the knee unit stretches during knee flexion (early swing)and recoils to extend the knee(late swing) -an internal exten
mechanical stabilizer -most knee units do not have a device to increase stability -the prosthetic knee is aligned posterior to a line extending from the trochanter to the ankle assisting in maintaing knee extension -a manual lock is a pin that limits knee flexion and is rele
Socket AK -designed to be a total contact device that emphasizes loading on PRESSURE TOLERANT structures such as the ischial tuberosity, gluteal muscles, lateral side of the thigh and to a lesser extent the distal end of the amputation -it limits the load on the P
Quadrilateral socket AK -MOST COMMONLY USED FOR AKA -uses a horizontal posterior shelf to support the ischial tuberosity and gluteals -the medial wall is the SAME height as the posterior wall while the anterior and lateral walls are 2.5-3" higher -reliefs are provided for th
What types of suspension are there for an AKA -suction -silesian bandage -metal pelvic band
Suction suspension for AK -employed to maximize contact and suspension -air is pumped out a one way valve during weight bearing -the individual wears a sock -suction can be partial or total
Silesian bandage suspension for AK -a strap that anchors the prosthesis by reaching around the pelvis -controls for rotation
Metal pelvic band suspension for AK -Includes a hinged hip joint attached to a leather/metal band anchored around the pelvis -adds control for rotation, hip ADD/ABD -REDUCES TRENDELENBURG GAIT -adds extra weight
