Wonderful C2F3CF

Product Code: OTAP-PLAC-3185

The finish is visible. What carries the load is not.

A coloured pylon is chosen partly for how it looks, which is the one property of it a buyer can assess from a photograph. Material, wall thickness and rating are the properties that decide whether it is safe to fit. Listed on Medigear.uk for UK business buyers.

There is a particular difficulty in buying a finished component. The finish is the most visible property and the least important one, while the properties that determine whether the part is fit for a patient are entirely concealed by it.

A pylon carries body weight between socket and foot, in compression and in bending, at roughly a million cycles a year for an active walker. What it can carry depends on three things: the material, the outside diameter and the wall thickness. None is visible on a finished tube. An anodised aluminium pylon and a carbon composite pylon of identical outside diameter look similar under colour, weigh differently, and carry different loads.

That is why the discrepancy on this reference matters rather than being a cataloguing curiosity. A code ending in CF invites a buyer to record the tube as carbon fibre. If it is anodised aluminium, the rating is different, the mass is different, and a clinic that has logged it wrongly has an inaccurate record of what a patient is walking on. The correction is simple and belongs at order: obtain the material, the wall thickness and the maximum body weight in writing from the manufacturer.

Beyond that, the tube behaves as any pylon does. Diameter governs compatibility, since modular systems use two sizes and no adaptor bridges them, so every clamp and fitting in the build must match. The tube is cut at the bench for one patient, with the arithmetic allowing for the insertion depth at each end, because tube sitting inside a clamp is not available as length. The cut face must be square so the tube seats, and deburred so no raised edge scores a clamp bore or prevents full seating. A published minimum usable length prevents a tube being cut so short that the required engagement cannot be achieved at both ends.

One consideration is specific to a finished tube. Cutting exposes the substrate, and the cut end will not match the rest. Where that end sits inside a clamp it will not be seen; where it does not, a trim or cap is needed. On a component chosen because it is visible, that is worth establishing before the first one is cut.

This is a component supplied for fitting within a prosthesis by a qualified prosthetist, who measures the patient, cuts and finishes the tube and assembles it to the specified insertion depths and torques. The manufacturer, material, diameter, wall thickness, rating, lengths and cut end treatment 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.

Uncovered transtibial builds are where a coloured pylon is most often specified.

Limb length is established by cutting the tube, as on any pylon.

Higher load builds are commonly specified on the larger tube diameter, which every fitting must match.

Clinic records depend on accurate material and rating data, since these determine what a patient is walking on.

Cut ends that remain visible need a trim or cap, which bears on how the finished limb looks.

Users selecting a colour are choosing the most visible element of an exposed build.

Services holding coloured stock need sizes as well as colours to fit without delay.

Colour Chosen, Structure Verified

The finish is selected by the user while the specification that matters is obtained in writing.

Material Established Before Fitting

Rating and mass both follow from material, and it cannot be judged from a finished surface.

Accurate Records for the Clinic

Knowing what the tube actually is keeps a patient's record of components correct.

Diameter Matched Through the Build

Every clamp, adapter and fitting shares one tube diameter, settled at specification.

Length Set to the Individual

The tube is cut so the assembled limb matches the contralateral side.

Insertion Allowed for in the Cut

Tube inside a clamp is not available as length, and accounting for it avoids a short limb.

A Square, Deburred Cut

Seating depends on a square face, and deburring prevents an edge scoring a clamp bore.

Minimum Usable Length Respected

Cutting above the published minimum keeps the required engagement achievable at both ends.

Cut End Addressed

Whether the exposed end sits hidden in a clamp or needs a cap is settled before cutting.

Reference Structure Clarified

What the leading C, the numeric and the trailing CF denote is established rather than assumed.

Instructions for Use

The C2F3CF is a structural pylon tube supplied with a coloured finish, and it illustrates a difficulty particular to finished components: the finish is the most visible property and the least important, while everything determining whether the part suits a patient is concealed beneath it. A pylon carries body weight between socket and foot in compression and bending, at roughly a million cycles a year for an active walker, and what it carries depends on material, outside diameter and wall thickness, none of which is visible once a tube is coloured. That is why the reference matters here. A code ending in CF invites a buyer to record the tube as carbon fibre, while the anodised lustre shown is characteristic of aluminium, and if the record is wrong then the rating and mass logged against a patient's limb are wrong too. The remedy belongs at order rather than after it. Otherwise the tube behaves as any pylon does, cut at the bench with allowance for insertion depth at each end, a square deburred face and a published minimum usable length, with the additional question of what happens to the finish at the cut. Cutting and fitting are the work of the prescribing prosthetist. Material, diameter, wall thickness, rating and lengths are provided by the seller at quotation alongside UKCA or CE documentation. Medigear.uk lists the tube 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 structural pylon tube for a modular lower limb prosthesis, supplied with a coloured finish. The reference structure and material should be confirmed.

Confirmed at quotation. The reference ends in CF, which normally denotes carbon fibre, while the finish shown is characteristic of anodised aluminium.

Because a finish conceals the substrate. Tubes of different materials and wall thicknesses look alike under colour and carry different loads.

Material, outside diameter and wall thickness together. None of the three is visible on a finished tube.

Yes. A clinic's record of what a patient is walking on should be accurate, and rating and mass both follow from the material.

The two were supplied with the same photograph and differ by one digit. What the numeric series denotes is unestablished.

No. Four base numbers exist across this tube range and modular systems use only two diameters, so the series denotes something else.

Confirmed at quotation, and every clamp and fitting in the build must match it.

The substrate is exposed at the cut end. Whether that end sits inside a clamp, or needs a trim or cap, is confirmed at quotation.

Tube sitting inside a clamp is not available as length, so the cut must allow for it at both ends.

A qualified prosthetist, who measures the patient, cuts and finishes the tube and assembles it to the specified depths and torques.
