We report a variant of tibial hemimelia in a six-year-old boy that did not comply with recognised classification systems. The femur and knee were normal, but the fibula was displaced proximally and there was severe diastasis of the proximal and distal tibiofibular joints to the extent that a grossly deformed foot articulated with the fibula and there was separate soft-tissue cover for the dista...

The Motion Foot is a new foot/ankle system that offers near-normal ankle range of motion via a hydraulic ankle (ROM = 50 deg), paired with an energy-storing foot plate. This system has been developed to offer to above-knee and below-knee prosthesis wearer: 1) improved comfort, 2) reducedloads on proximal joints and 3) improved stability. Improved comfort and reduced proximal joint loading is ac...

Understanding muscle architecture of the foot may assist in the design of surgical procedures such as tendon transfer, biomechanical modeling of the foot, prosthesis design, and analysis of foot function. This paper primarily focuses on the variation of Flexor Digitorum Longus and Brevis muscles of foot. Sixty inferior extremities were dissected. While dissecting a body of adult female we obser...

Today, Inertial Measurement Units is used for control in lower extremity prosthesis studies. In this article, an application related to the analysis and classification of foot movements such as dorsiflexion, plantarflexion, inversion eversion presented. This study aims perform recognize movement pattern adapt abnormal walking conditions robotic system. Nine parameters are measured with motion d...

Stump length is an important factor in attaining successful prosthetic rehabilitation in below-knee (BK) amputees. Stability of the stump-prosthesis complex is impaired in the case of a stump shorter than 10 cm. Thus, fitting a prosthesis to a BK amputee with a stump which is very short often requires the use of different prosthetic techniques. In this work, the authors suggest the use of a Swe...

This article presents a virtual prototyping study of a semi-active lower limb prosthesis to improve the functionality of an amputee during prosthesis-environment interaction for level ground walking. Articulated ankle-foot prosthesis and a single-axis semi-active prosthetic knee with active and passive operating modes were considered. Data for level ground walking were collected using a photogr...

Some important walking functions are adversely affected or eliminated in prosthesis users because of reduced or absent ankle motion. This retrospective data analysis determined the effect of prosthetic ankle units on the characteristics of the ankle-foot roll-over shape in persons with bilateral transtibial amputations. Seventeen subjects were fitted with Endolite Multiflex Ankles to provide an...

Today, often ankle’s active prosthesis is used for transtibial amputated people’s walking, because these prostheses have some advantages such as increasing power and decreasing metabolism. In most of active prosthesis in order to create a movement or increase the force at the push-off, electrical actuators are used like a motor. In cases where a higher-power motor is necessary, the capacity, we...
