Transtibial Prosthesis merupakan Prosthesis untuk amputasi pada tulang Tibia (tulang betis).

agar Transtibial Prosthesis ini tidak lepas saat pasien mengayun berjalan , maka desain bagian supracondylar (bagian diatas lutut) dibuat menekan untuk suspensi (pengait).

The solid-ankle prosthetic feet in this study with excessively flexible forefoot sections produced similar effects on gait of users with a unilateral transtibial prosthesis as prosthetic feet with short arc lengths. When prosthetic feet have excessively flexible forefoot sections, they provide shorter effective foot lengths, reducing ankle moments on the prosthetic side and leading to a "drop-off" effect when transitioning load from the prosthesis to the sound limb.

Suspension devices should keep the prosthesis firmly in place during use and allow comfortable sitting. Several types of suspension exist, both for the transtibial and transfemoral amputation. Common transtibial suspensions include sleeve, supracondylar, cuff, belt and strap, thigh-lacer, and suction styles. Sleeves are made of neoprene, urethane, or latex and are used over the shank, socket and thigh. Supracondylar and cuff suspensions are used to capture the femoral condyles and hold the prosthesis on the residual limb. The belt and strap method uses a waist belt with an anterior elastic strap to suspend the prosthesis, while the thigh-lacer method uses a snug-fitting corset around the thigh. The suction method consists of a silicone sleeve with a short pin at the end. The sleeve fits over the residual limb and the pin locks into the socket. With a transfemoral prosthesis, suction and several types of belt suspension also are available.

The socket contacts the residual limb and disperses pressure around it. A hard socket offers direct contact between the limb and the socket, resulting in decreased friction, no liner bulk, easy cleaning, and increased durability. It is, however, difficult to fit and adjust in response to residual limb changes. A soft socket includes a liner as a cushion between the socket and residual limb. This provides additional protection for the limb but may increase friction and bulk. Transtibial socket types include: patellar tendon-bearing (PTB), silicone suction, energy-storing, or bent-knee designs. Transfemoral socket types include: quadrilateral, ischial containment, and contoured adducted trochanteric-controlled alignment method (CAT-CAM) designs. A prosthetic sock is usually worn to help cushion the limb from forces and accommodate for volume changes. Prosthetic socks are available in a variety of materials and thickness, and may be worn in layers to achieve the most comfortable fit.

A lower limb prosthesis is an artificial replacement for any or all parts of the lower extremity (leg).

Transtibial suspension systems: (a) Seal-In X5 liner (Össur; Reykjavik, Iceland) with transparent socket and valve and (b) Dermo liner (Össur) with transparent socket and shuttle lock.

Two transtibial prostheses () were manufactured for each subject. Two different suspension systems were used: Seal-In X5 liner with valve (Icelock Expulsion Valve 551, Össur) and Dermo liner with shuttle lock (Icelock Clutch 4H 214, Össur). All prosthetic feet were Flex-Foot Talux (Össur) [16,18].

Transtibial prosthetic suspension: Less pistoning versus ..

The shank corresponds to the anatomical lower leg, and is used to connect the socket to the ankle-foot assembly. In an endoskeletal shank, a central pylon, which is a narrow vertical support, rests inside a foam cosmetic cover. Endoskeletal systems allow for adjustment and realignment of prosthetic components. In an exoskeletal shank, the strength of the shank is provided by a hard outer shell that is either hollow or filled with lightweight material. Exoskeletal systems are more durable than endoskeletal systems; however, they may be heavier and have a fixed alignment, making adjustments difficult.

In order to be eligible for the study, subjects with transtibial amputation were required to be unilateral, without pain or ulcer on the residual limb, and with a residual-limb length not less than 13 cm. Furthermore, they could not have volume fluctuation in the residual limb, could not depend on assistive devices such as a cane or crutches for ambulation, and had to have good upper-limb strength.

We fixed 16 reflective markers to the subjects’ lower limbs in accordance with the Helen Hayes marker set. The knee and tibia markers for the prosthetic leg were located on the lateral proximal socket wall and the lateral distal end of the socket, respectively (). We placed two additional markers on the liner under the knee joint level (LLin1) and 5 cm below that (LLin2) [16].

PROSTHETICS TYPES AND CAUSES OF PROSTHETIC GAIT DEVIATIONS

There are several levels of lower limb amputation, including partial foot, ankle disarticulation, transtibial (below the knee), knee disarticulation, transfemoral(above the knee), and hip disarticulation. The most common are transtibial (mid-calf) and transfemoral (mid-thigh). The basic components of these lower limb prostheses are the foot-ankle assembly, shank, socket, and suspension system.
