Wonderful UASL

The UASL belongs in prosthetic and orthotic clinics, limb-fitting centres and the workshops where upper limb prostheses are made. Prosthetists and prosthetic technicians choose it when a transhumeral arm is to be suspended from a silicone liner, and they build it into the prosthesis between that liner and the rest of the arm.

Its users are people whose arm ends between the shoulder and the elbow and who wear a silicone liner on the residual limb. For them the lock is the connection that matters most in the whole build, because the elbow, forearm and terminal device all hang from it. A focused part suits that position: the UASL has one purpose, so its role in the suspension is plain to the clinician planning it and to the wearer living with it.

Daily use follows a set order. The liner goes on first, rolled onto the upper arm, and the prosthesis follows over it, with the UASL holding the two together from then on. Occupational therapists and prosthetists teach this sequence during rehabilitation sessions, so that putting the arm on becomes a routine the wearer manages independently at home.

Clinics that fit transhumeral arms on silicone liners can work with one dedicated aluminium lock for that job, identified by a single item number from first fitting to replacement. Its place in the build makes it relevant at every follow-up visit, because a secure hold between liner and prosthesis is what lets the rest of the arm do its work. Aluminium gives that hold a metal body at the top of the arm, close to the residual limb.

One part, one purpose

The UASL exists to hold an upper arm prosthesis to a silicone liner. A component with a single role keeps the suspension plan simple to explain and simple to follow.

Made for the transhumeral level

Its name ties it to the upper arm. Clinicians fitting a limb that ends above the elbow have a lock whose level matches the fitting from the start.

Matched to silicone liner suspension

The lock belongs with a silicone liner, so a clinic that suspends transhumeral arms on liners has a part designed around that method.

Aluminium throughout

Aluminium forms the lock, giving the link between liner and prosthesis a metal body at the point where the whole arm is held.

The arm stays with the wearer

Once the prosthesis is on, the lock keeps it attached to the liner, so the elbow, forearm and hand travel with every movement of the residual limb.

A clear routine for putting the arm on

Liner first, prosthesis second, lock holding both. That fixed order is easy to teach in rehabilitation and easy for the wearer to repeat each morning.

One item number to reorder

Item No. UASL identifies the lock. A clinic replacing the part later orders the same number it fitted the first time.

A defined role in follow-up care

Because the UASL is the one part holding the arm to the liner, follow-up appointments know where suspension sits in the build and which item number covers it.

Upper arm silicone lock

The full product name is Upper arm silicone lock. It states the level, the suspension method and the function in four words.

Item No. UASL

Wonderful identifies the lock as Item No. UASL, the number that appears on orders and in the prosthesis records.

Aluminium construction

The material is aluminium, written by Wonderful as AL.

Transhumeral application

Designed for the upper arm, the lock serves residual limbs that end between the shoulder and the elbow.

Silicone liner suspension

A silicone liner rolled onto the residual limb carries the prosthesis, and the lock connects the prosthesis to that liner.

Link between liner and prosthesis

The UASL sits in the build between the liner and the rest of the arm. All of the arm below it depends on that connection.

Single component

The UASL is one lock, a single aluminium part with a defined place in the transhumeral build.

Hold through daily wear

From the moment the arm goes on until it comes off, the lock keeps the prosthesis held to the liner.

Part of the prosthetist's build

Prosthetists and technicians build the lock into the arm, planning it together with the wearer's liner and socket.

Donning sequence

The liner goes on first and the prosthesis follows, at which point the lock takes over the job of holding the two together.

Focused design

Every aspect of the UASL points at one task. Its level, its suspension method and its function are all fixed by its name.

Metal body at the point of suspension

Its aluminium body sits where the full weight of the arm below is carried, between the wearer's liner and the prosthesis.

The UASL suits prosthetic clinics and limb-fitting workshops that suspend transhumeral arms from a silicone liner and want one dedicated lock for that connection. Its case rests on focus. It is an aluminium part made for the upper arm, for silicone liner suspension and for the single job of holding the prosthesis to the liner, so the clinician knows exactly what it is there to do. Wearers gain an arm that stays with the residual limb from morning until night, whatever sits below it. For a service fitting arms above the elbow on silicone liners, it gives one item number for every build of that kind. Wonderful makes the UASL in aluminium under Item No. UASL.
