Alpha® Upper Extremity Liners

An adaptation of the lower extremity Alpha Classic® Liner, Alpha Upper Extremity Liners are designed exclusively for transradial and transhumeral amputees. Alpha Classic gel consists of a skin-friendly and non-reactive blend of thermoplastic elastomer (TPE) gel with mineral oil and vitamin E, suitable for patients suffering from silicone allergies. The gel flows to adapt to uneven socket pressures and optimise pressure distribution, while its low rebound means the liner maintains its adapted shape over time. The liners are heat mouldable, allowing clinicians to heat and stretch them when needed.
