Socket Technology

Notwithstanding the use of good quality components (socket, lock and sleeves) or a high performing suspension system, the prosthetic fit is of paramount importance.  A comfortable prosthetic socket will ensure a successful rehabilitation outcome.  At Roger Wolfson and Associates we pride ourselves in having achieved a combined 50 years’ worth of experience in prosthetic socket fittings.

Sockets are custom-made by Roger Wolfson and Associates and tailored to suit individual needs.

Icecast Anatomy

Icelandic Direct Casting (IDC) sockets are fabricated with the Icecast® Anatomy pressure bladder and the Icelock® 600 series of locking and attachment components.  The Icelock series allows for interchangeable suspension (pin, lanyard, valve), which obviates the need for the construction of a new socket.

Features

  • IDC provides a total surface bearing socket through even pressure distribution during casting and fitting.
  • IDC guarantees a replicable socket fitting.
  • IDC communicates with users direct in addressing specific problem areas.

Using the Icecast® Anatomy pressure casting, the prosthetist undertakes a unique socket making process.   Integrated ContourCell® shaping chambers can be inflated to achieve an anatomically correct socket shape.  The increased control over the socket shape enhances user comfort and stability.

Pressure Pads

Pressure Pads are specifically designed to relieve pressure on bony prominences and other sensitive areas of the residual limb.  Pressure Pads are made using a unique blend of silicone and provide user comfort in that they enable pressure redistribution and equalization.

Iceflex® Endurance

The Iceflex® Endurance suction suspension sleeve is designed to fit over any definitive prosthetic socket.

When used with a distal locking device, it provides additional user security. In some cases, the Iceflex® Endurance can serve as a locking device in itself when used over a liner and definitive socket with a suction valve, ensuring that no air enters the definitive socket from above.

Features

  • Enhanced security and stability.
  • Pre-flexed to facilitate knee flexion.
