Artificial Lower limb Extrimity

Ideal Artificial limbs Solution (I.A.S) specializes in the fitting of lower extremity prosthetic devices. Statistically these are the most common types of prostheses required by persons with limb amputations. We are committed to working closely with our clients to produce devices that are comfortable, functional, appropriate for their needs and cosmetically attractive. The following is an overview of some of the products relating to this area of prosthetics. Please contact us at our office to discuss your needs.

There are seven basic prosthetic options to consider for the person with a lower extremity amputation:

  • Partial Foot Prosthetics
  • Complete Prosthetic Feet
  • Shock Absorbers and Rotators
  • Prosthetic Knees for Artificial Limbs
  • Prosthetic Interface Materials
  • Prosthetic Socket Design and Suspension
  • Cosmetic Covers
Partial Foot Prosthetics

Partial foot amputations are fit with prosthetic devices ranging from simple toe-fillers in shoes for toe amputations, to custom-molded silicone prosthetics that incorporate contoured arch supports and carbon fiber keels. A comfortable fit, control of weight-bearing forces and adaptation to the needs of each individual are the most important features of this type of prosthesis. In some instances it may be necessary to purchase slightly larger or extra-depth shoes to accommodate the arch support or prosthesis required.

For persons with Diabetes, a comfortable and supportive pair of shoes with a soft sole and uppers is important to safeguard feet against any further injury.

Complete Prothetic Feet

Prosthetic foot design and construction has progressed tremendously in the past few decades and now commonly incorporates carbon fiber structures to reduce weight and improve energy return. Some feet have terrain adapting and shock absorbing features, while others are more suitable for special purposes such as swimming. Most high-end feet can be 'tuned' to suit each individual by adjusting or exchanging internal elastomer bumpers or wedges, and are custom ordered from the manufacturer to specifications for each client. Prosthetic feet are selected by considering each individual's activity level and the type of terrain that they will be traversing. We encourage our clients to become familiar with the different types of prosthetic feet available, to assist in the selection of the most appropriate type for them.

Prosthetic feet, like knees, hips, and other components incorporated into a prosthesis, can be grouped according to a recognized functional level classification system:

  • 1. Low Impact Level:
  • Daily activities involving limited and steady walking with the use of a walking aid.

  • 2. Moderate Impact Level:
  • Daily activities involving normal walking, with the ability to demonstrate varied cadence.

  • 3. High Impact Level:
  • Daily activities involving fast walking, jogging and climbing stairs. Example: Light manual labor, recreational sports.

  • 4. Extreme Impact Level:
  • Daily activities involving rigorous walking, running and heavy lifting. Example: Heavy manual labor including lifting, track and field sports.

Single Axis

A hinged ankle joint is incorporated into the prosthetic foot. Rubber bumpers within the ankle structure absorb ankle motion induced by body weight.

Single Axis
Multi Axis (Moderate Impact Level)

Rubber bumpers in the ankle mechanism permit a rocking motion of the foot from heel to toe as well as from side to side. This can be useful for walking on uneven terrain. Generally these feet do not have much stored energy return and they have a softer feeling underfoot than the SACH feet.

Single Axis
Stored Energy (Moderate to High Impact Level)

These feet have an internal structure that acts like a spring. This spring will store energy and return this energy to the amputee, propelling them forward, as the toes of the prosthetic foot leave the ground. Some of the designs are virtually maintenance-free, while others incorporating internal bushings and bumpers require regular servicing to maintain optimal performance. Most of these feet have terrain-adapting features that absorb irregularities in the ground and improve performance on inclined surfaces. Some of the photos show the prosthetic feet without their accompanying cosmetic covers.

Stored Energy
Advanced Features Stored Energy (Moderate to High to Extreme Impact Level)

These feet incorporate multiple features such as energy storage and return, shock absorption and rotation, and terrain adaptation. Suitable for prolonged walking, running and jumping they can be used both in daily ambulation and in sports.

Shock Absorbers and Rotators

Rotators, with or without accompanying shock absorbers, are good additions to most lower extremity prosthetic devices. While they do add weight to a prosthesis, they reduce torsional stress on tissue. A rotation unit is definitely an asset to playing golf, and some units can be 'tuned' to suit the preferences of each individual.

Shock Absorbers and Rotators
Prosthetic Knees for Artificial Limbs

Like prosthetic feet, the type of prosthetic knee selected for each individual is determined based on their intended activity level and the type of terrain that they will be traversing. These knee units can be similarly grouped into categories associated with the four main Impact Levels.

Children, Youth and Adults have access to many of the same classifications of knee units, built to suit their weight range and activity levels. Contact us at I.A.S to inquire about various prosthetic knee options.

Prosthetic Interface Materials

A prosthetic interface is that material located closest to the wearer's skin, whether it be the traditional fine nylon sheaths and stump socks or the newer urethane, polymer gel and silicone liners with or without integral suspension pins. At I.A.S we strive to match each individual with the most appropriate interface and prosthetic suspension system. Each type of system requires routine cleaning to maintain good hygiene and healthy skin. We also carry a number of skin care lotions and ointments to be used separately from or together with the various types of gel liners. Considerable relief from pressure and friction-related skin problems and effective management of persistent scar tissue can be obtained through the use of a carefully shaped and supportive prosthetic socket coupled with the correct interface material.

Prosthetic Socket Design and Suspension

I.A.S provides state-of-the-art prosthetic socket design and components. Comfort begins with a properly designed socket. We use careful hand-casting techniques and build prostheses that both support weight bearing and relieve pressure regions. We use flexible inner socket liners to allow the limb musculature to expand and contract throughout the gait cycle. In our above-knee prosthetic designs this flexible liner is supported by a lightweight rigid frame, which attaches to the prosthetic knee of choice. Many types of prosthetic suspension systems, including suction fitting and locking pin mechanisms are used. We use all of the advanced technology feet that will enhance the function of each prosthesis.

Cosmetic Covers

I.A.S can provide very realistic looking cosmetic covers over below knee and above knee prostheses using custom colored latex and silicone skins. Inquire for more details.

"Not only do they fit correctly, but my chronic feet and knee pains have become only 'once and a while' pains vs non-stop every day pain."

Md. Mehboob Meerut

"I used to have constant heel pain due to 2 spurs on each foot, Achilles pain and low back pain. I no longer have any of those pains as long as I am consistent in wearing my orthotics."
