PRESSURE TOLERANT TISSUES TRANSFEMORAL BIOMECHANICS •Socket Longer amputation limb provides more area for medially directed

providing pressure relief for the less pressure tolerant areas like adductor tendon and pubic ramus. The medial brim extends posterior to enclose ischial ramus and dips

Describe the indications for, functional characteristics of, and advantages and limitations of the most commonly used transfemoral components and suspension strategies. 2. Compare and contrast the design, fit, and function of the four most popular… Transfemoral Pressure-tolerant areas: Ischial tuberosity, Gluteals, Lateral sides of residual limb, Distal end (rarely, may become sensitive) 2 types of shanks or pylons 2020-05-14 23 Transtibial Prosthetics David Knapp Learning Objectives On completion of this chapter, the reader will be able to do the following: 1. Describe the principles underlying current transtibial socket design. 2. Discuss the pros and cons of the various options for prosthetic suspension.

2001-02-01 Transfemoral socket design continues to evolve as various theories are introduced and incorporated into the field of study. General weight tolerant areas of the residual limb will be discussed and related to several common socket design approaches. Transfemoral Amputation muscle wasting • With aim of MRI the amount of atrophy in muscle in stump after 2 years was assessed & revealed A. Muscle that are not sectioned like G.medius, minimus, iliopsoas has 30% atrophy B. Muscles that lost insertion indirectly like G.maximus & tensor fascia lata due to non-attachment of fascia lata showed Ambulation with b/l transfemoral amputation will… The main risks that physical security components… Hoovers actions to combat the Great Depression; Above knee amputation through the femur; Amputation of both lower limbs and the pelvis below… Pressure tolerant areas of the typical transtibial… Amputation through elbow; Transmetatarsal A Total Surface Bearing socket (TSB) means that the pressures are spread more evenly over the entire limb. The use of a silicone or urethane interface flows over the limb, thinning out over pressure tolerant areas and remaining thick over areas that are pressure sensitive. Weight bearing is done via total contact along pressure tolerant areas and relief along boney prominences. Knee disarticulation (through knee) This level of amputation goes directly through the middle of the knee.

Excessive pressure can lead to severe skin breakdown, infection, surgical revision, loads during weight bearing to minimize focal loading on pressure intolerant tissues. Unilateral revision or reconstruction of transtibial amputation 3. ers from different geographical regions.

Pressure can be managed by increasing the area it is applied over and distributing it thoughtfully to pressure tolerant areas. Alignment of a lower limb prosthesis can have an effect on socket pressures in a predictable way Changes to a prosthesis can alter the prevailing biomechanical situation through limiting ranges of motion or moving the GRF.

• The transfemoral group presents a larger center of pressure displacements under the amputated leg than the transtibial group. CONCLUSION: These data emphasize the role played by the differences between the center-of-pressure magnitudes intervening under the sound and amputated legs and the size of the prosthesis-stump contact area in these postural strategies.

Transtibial. Ideally 20-50% of tibial length preserved. This stands in contrast to traditional socket designs, which are based on tissue containment and uniform tissue loading, in the case of hydrostatic socket designs, 4 or selective loading of pressure-tolerant areas, in the case of ischial-ramus containment (IRC), 5 quadrilateral, 7 and patellar tendon-bearing designs. 8 The HiFi system was originally developed as an upper-limb application but has been used regularly for persons with TF and knee-disarticulation amputation and has most recently 2020-06-01 · Prosthetists use these areas to create a comfortable transfemoral socket by applying pressure on the pressure tolerant regions and avoiding it in sensitive ones, in order to attach the socket to the residual limb. Furthermore, the scar is considered a region of high sensitivity where pressure, or even contact, is avoided. Fig 18B-24.

However, because less than 5% of amputations are knee disarticulations, statements about statistical significance cannot be made. In the area of the foot more than 12 different amputation levels are known.
