Prosthetic and orthotic options for lower extremity amputation and reconstruction

Abstract

Lower extremity injury and deformity can result from a number of etiologies. Regardless of the underlying cause, the decision to pursue amputation or reconstruction of a lower limb is challenging for both patients and practitioners. This decision is largely dependent on the patient's premorbid health and function, functional goals and preferences, and characteristics and viability of the affected limb. The role of adaptive devices following surgery should never be underestimated. Advances in prostheses and orthoses have provided patients with a wider range of options to consider when deciding between limb reconstruction and amputation. The primary goals of any adaptive device are to improve function, prevent recurrence or ulceration of the defect, and allow for use of conventional footwear and/or clothing. When a lower extremity amputation is indicated, selection of the correct level is of critical importance in order to optimize healing potential and function. Each distinct level has certain inherent prosthetic and orthotic considerations. Likewise, the application of an adaptive device following reconstruction of the lower extremity also has demonstrable benefits and must be tailored to the specific defect and procedure performed. Knowledge of available prosthetic and orthotic options is of considerable importance for the reconstructive surgeon tasked with limb salvage or resurfacing an amputated extremity. This article reviews considerations of various types of lower extremity amputation and reconstruction, and provides a framework for the role of adaptive devices following surgery.

Prosthetic Arm with Functional Fingers and Wireless Recharge on Walk Function

“…The piezoelectric generates AC power, which is supplied directly into the trouser pocket's charging pad (transmitter). The piezoelectric generator's battery charging efficiency is tested experimentally to find the best material and number of piezoelectric plates to employ for this purpose [5]. As long as the user wears footwear with the implanted plate while walking, the piezoelectric generator will be able to provide a steady supply of power to the charging pad.…”

Prosthetics for Lower Limb Amputation

“…STEP 1-Sit down and remove the suspension system STEP 2-Remove the socket by slipping it off from the residual limb STEP3-Check the limb for any signs of skin breakdown [5].…”

Therapeutic benefits of lower limb prostheses: a systematic review

“…After lower limb loss, assistive devices are a fundamental part of rehabilitation with the aim to restore daily activities and improve quality of life [ 3 – 5 ]. A prosthesis is generally favoured among assistive devices as it enables one to carry out daily activities as naturally as possible [ 4 , 6 , 7 ]. It additionally helps to enhance self-esteem as it ensures that people diverge as little as possible from the physical appearance of able-bodied individuals [ 8 ].…”
