Product Code: OTAP-PLAC-2996

Foot flat reached sooner, with bumpers tuned to the user.

A single axis foot pivots about one transverse axis, with a compressible bumper on each side of it. Those bumpers set how readily the foot moves into plantarflexion and dorsiflexion, and changing them changes how the foot behaves. Listed on Medigear.uk for UK business buyers.

At heel strike, the foot has to get from heel contact to flat on the ground. How quickly that happens, and what resists it on the way, shapes what the rest of the limb experiences.

A single axis foot puts one transverse pivot at the ankle and a compressible bumper on either side of it. Coming out of heel strike the posterior bumper compresses and the foot rotates into plantarflexion, reaching flat contact promptly. Later in stance, as the body passes forward over the foot, the anterior bumper compresses and resists dorsiflexion, controlling how fast the shank travels over the fixed foot. Typical single axis designs allow rather more plantarflexion than dorsiflexion, and the range available on this foot should be established from the manufacturer.

Reaching foot flat early is what makes this design useful above the knee. Once the foot is flat, the ground reaction force can move forward of the knee sooner, and a force line in front of the knee helps hold it extended rather than letting it flex. For a transfemoral user in early stance that is a meaningful contribution to stability, and it is the mechanism behind the manufacturer's statement that the foot is particularly useful for amputees above the knee.

The bumpers are the tuning point. Their firmness, measured as durometer, determines how much resistance each direction offers, and swapping bumpers changes the foot's behaviour without changing anything else in the build. A user who needs the knee held more firmly in early stance, or one who finds the shank rolling forward too quickly, can be addressed by bumper selection. That adjustability is a practical advantage: a prosthetist can respond to how a user actually walks rather than re-specifying the component.

The bumpers are equally the maintenance point. They are compressible parts working under full body weight at every step, in a joint sitting close to the ground where dirt and moisture reach, so periodic inspection and replacement are part of owning the foot. Replacement availability and the service interval are worth settling at purchase.

The foot is supplied in polyurethane with shaped toes, in a beige finish, and it attaches through a foot adapter, with the attachment method and compatible adapters to be established for the build.

This is a component rather than a finished prosthesis. It is selected, aligned and fitted by a qualified prosthetist as part of a limb assembled around the individual, and suitability, bumper selection and alignment are clinical decisions taken by that professional. The manufacturer, specification, range of motion, bumper options, per-size load rating, adapter compatibility and handing are provided by the seller at quotation, with UKCA or CE marking documentation, the declaration of conformity, instructions for use and warranty terms issued by the manufacturer or held by the seller.

Above-knee prosthetic fitting is the application the manufacturer highlights, since reaching foot flat sooner supports knee extension in early stance.

Users needing stance stability at initial contact are served by a design that moves the ground reaction force forward of the knee earlier.

Transtibial fitting is also supported, with the foot selected and aligned by a prosthetist within the limb.

Users whose walking changes during rehabilitation are served by bumper swaps, which alter the foot's response without changing the build.

Shank progression that feels too fast or too slow can be addressed by anterior bumper firmness.

Services planning maintenance need bumper replacement availability and the service interval established, as these are wearing components.

Clinics fitting across a range of patient sizes are served by a size range spanning the adult foot, with the figures confirmed for this item.

Flat Contact Reached Promptly

The posterior bumper compresses out of heel strike, letting the foot rotate to flat rather than holding a fixed angle.

Knee Extension Supported in Early Stance

With the foot flat sooner, the ground reaction force moves forward of the knee earlier, which helps hold it extended.

Shank Progression Controlled

The anterior bumper resists dorsiflexion later in stance, governing how quickly the shank travels over the fixed foot.

Tuned by Changing a Component

Bumper durometer is the adjustment, so the foot's behaviour can be altered without re-specifying anything else in the build.

Responsive to How a User Actually Walks

A prosthetist can adjust after seeing the user walk, rather than committing to one response at specification.

A Simple Mechanism

One axis and two bumpers keeps the moving parts few and the adjustment straightforward.

Shaped Toes for Appearance

Moulded polyurethane with shaped toes supports appearance under a cosmesis or sock.

Service Points Identified

Bumpers are wearing components, and replacement availability and inspection interval are established at purchase.

Per-Size Load Limit Established

A maximum patient weight for the size supplied is obtained rather than a published band.

Specification Confirmed for This Item

Figures are established as belonging to this foot rather than shared with another product in the range.

The 1F40 is a single axis prosthetic foot with ankle articulation about one transverse axis and a compressible bumper on either side of it. Coming out of heel strike the posterior bumper compresses and the foot rotates promptly to flat contact; later in stance the anterior bumper resists dorsiflexion and controls how quickly the shank travels over the fixed foot. Reaching foot flat early is what makes the design useful above the knee, because the ground reaction force can then move forward of the knee sooner and help hold it extended, which is the mechanism behind the manufacturer's note that the foot particularly suits amputees above the knee. The bumpers are also the tuning point: their firmness determines the resistance in each direction, so a prosthetist can change how the foot behaves after watching the user walk, without altering anything else in the build. They are equally the maintenance point, working under body weight at every step close to the ground. Selection, bumper choice and alignment are clinical decisions for the prescribing prosthetist. The specification for this item, range of motion, bumper options, per-size load limit and adapter compatibility are provided by the seller at quotation, alongside UKCA or CE documentation and instructions for use. Medigear.uk lists the foot for UK business buyers and can arrange supply, documentation and the provision of consumables. Enquire for a written quotation.

FAQ

Frequently Asked Questions

Everything buyers need to know about sourcing medical equipment through MediGear.

It is a single axis prosthetic foot with ankle articulation about one transverse axis, supplied as a component for a prosthetist to fit within a lower limb prosthesis.

The foot pivots about one transverse axis at the ankle, allowing movement in the sagittal plane only.

The posterior bumper compresses coming out of heel strike, letting the foot rotate to flat contact, and the anterior bumper resists dorsiflexion later in stance.

Once the foot is flat, the ground reaction force can move forward of the knee sooner, which helps hold the knee extended in early stance.

Yes. The manufacturer notes the foot as particularly useful for amputees above the knee, and this mechanism is the reason.

Bumper firmness, measured as durometer, is the variable a prosthetist changes, and swapping bumpers alters the foot's behaviour without changing the rest of the build.

Confirmed at quotation. Single axis designs typically allow more plantarflexion than dorsiflexion, but the figures for this foot should come from the manufacturer.

The bumpers work under body weight at every step close to the ground, so periodic inspection and replacement are part of ownership.

Published as 21–29 cm at 280–460 g, though the same figures appear against another item in the range, so they should be confirmed for this one.

Published as a range of 100–110 kg. A maximum patient weight per size should be obtained before fitting.
