Product Code: OTAP-PLAC-2994

An articulated ankle letting the foot meet the ground evenly.

Where a foot has ankle articulation, it can rotate to sit flat against the surface it lands on instead of holding one fixed angle. The manufacturer describes ankle joint function ensuring the foot and the ground make even contact. Listed on Medigear.uk for UK business buyers.

Ground is rarely flat. A pavement cambers, a lawn undulates, a slope runs across the line of travel, and a foot held at a fixed angle meets all of those at whatever angle it was set to.

An articulated prosthetic foot addresses that by putting a joint at the ankle. The foot rotates about that joint under load, so it can come flat against a surface that is not level and distribute contact across the sole rather than loading one edge. The manufacturer describes this as ankle joint function ensuring the foot and the ground make even and safe contact, and it is the reason articulated designs are specified for users who spend time on uneven ground.

Articulation also changes what happens at the start of stance. With movement available at the ankle, the foot reaches flat contact sooner after heel strike, and once the foot is flat the ground reaction force can move forward more quickly. For a user with an above-knee prosthesis that matters, because getting that force line in front of the knee sooner supports knee extension and stance stability. The manufacturer notes the foot as being particularly useful for amputees above the knee, which follows from that mechanism.

Motion at an articulated ankle is normally controlled by bumpers, compressible elements that limit and resist plantarflexion and dorsiflexion and set how much movement is available in each direction. Bumper firmness is the tuning variable, and it is what a prosthetist adjusts to suit the user's weight and activity. The bumper arrangement on this foot, and whether firmness options are available, should be established.

Bumpers are also the maintenance point. They are compressible components working under load at every step, in a joint close to the ground where dirt and moisture reach, so periodic inspection and replacement are part of owning an articulated foot. The service interval and the availability of replacement bumpers are worth settling at purchase.

The foot is supplied in polyurethane, in sizes from 21 to 29 cm, with published weights from 280 g to 460 g depending on size, in a beige finish with shaped toes for appearance under a cosmesis or sock. It attaches through a foot adapter, and the attachment method and compatible adapters should 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, construction, axis arrangement, per-size load rating, bumper options, 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 highlighted by the manufacturer, since reaching foot flat sooner supports knee extension and stance stability.

Uneven ground including cambered pavements, grass and cross-slopes is where ankle articulation contributes most.

Users spending time outdoors or on varied surfaces are served by a foot that can conform to what it lands on.

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

Users needing a tuned response are served by bumper firmness selected to their weight and activity.

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

Clinics fitting across a range of patient sizes are served by a size range from 21 to 29 cm.

The Foot Finds the Ground

Ankle articulation lets the foot rotate to sit flat on a surface that is not level, spreading contact across the sole.

Foot Flat Reached Sooner

Movement at the ankle brings the foot to flat contact earlier after heel strike.

Support for Knee Stability

With the ground reaction force moving forward sooner, an above-knee user is helped towards knee extension in early stance.

Movement Set by Bumpers

Compressible bumpers limit and resist plantarflexion and dorsiflexion, defining how much movement is available in each direction.

Firmness Tuned to the User

Bumper selection is the variable a prosthetist adjusts to the user's weight and activity.

A Size Range Across Adults

Sizes from 21 to 29 cm at product weights from 280 g to 460 g.

Shaped Toes for Appearance

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

Service Points Identified

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

Per-Size Load Limit Established

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

Construction Settled Before Listing

The 1F41 is an articulated prosthetic foot published by the manufacturer as a double axis design. Ground is rarely flat, and a foot held at a fixed angle meets a cambered pavement or a cross-slope at whatever angle it was set to, while a joint at the ankle lets the foot rotate under load and come flat against the surface, spreading contact across the sole. Articulation also brings the foot to flat contact sooner after heel strike, which lets the ground reaction force move forward earlier, and that supports knee extension and stance stability in an above-knee user, which is the application the manufacturer highlights. Movement is controlled by bumpers resisting plantarflexion and dorsiflexion, with firmness the variable a prosthetist selects to weight and activity, and those bumpers are also the maintenance point since they work under load at every step close to the ground. The foot is supplied in polyurethane with shaped toes, in sizes from 21 to 29 cm at 280 g to 460 g. Selection, bumper choice and alignment are clinical decisions for the prescribing prosthetist. The construction, axis arrangement, per-size load limit, bumper options 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.

It is an articulated prosthetic foot published by the manufacturer as a double axis design, supplied as a component for a prosthetist to fit within a lower limb prosthesis.

That the foot carries ankle articulation about more than one axis, allowing movement in more than one plane. The exact arrangement on this foot is confirmed at quotation.

The foot can rotate to sit flat on ground that is not level, distributing contact across the sole instead of loading one edge.

Reaching foot flat sooner after heel strike lets the ground reaction force move forward earlier, which supports knee extension and stance stability.

Bumper firmness is the tuning variable a prosthetist works with, and the options available on this foot are confirmed at quotation.

Bumpers work under load at every step in a joint close to the ground, so periodic inspection and replacement are part of ownership. The service interval is confirmed at quotation.
