Carpal Arch Space Augmentation (CASA5.0)

Case ID:
UA22-144
Invention:

­This device is a non-invasive method for treating Carpal Tunnel Syndrome (CTS). By using radioulnar compression applied to the wrist and forearm, this approach precludes the need for surgery. This biomechanical technology allows patients to pursue a safer solution, with a short recovery period. 

Background:
Currently only 23% of those who have suffered from CTS are able to return to their old profession after surgery, according to National Institute for Occupational Safety and Health. Many patients may go through multiple surgeries, which can result in complications such as excessive scar tissue overgrowth and possibly leaving fingers devoid of sensation and without mobility.

This new device helps rehabilitate those with CTS without having to undergo surgery. A device that sits on the wrist and applies pressure to the radioulnar area of the forearm. Having proven that the methodology increases median nerve mobility over a relatively short treatment period, it helps patients recover without having to go through an expensive procedure. The CASA5.0 provides more flexibility and does not cause any permanent damage; because of this it can be used multiple times by those who have a chronic CTS condition.

Those suffering from CTS have limited non-surgical options for treatment, and those that do exist require an early diagnosis. Beyond the basic nonsteroidal anti-inflammatory drugs, patients can receive injections of corticosteroids which helps relieve swelling and pressure on the nerve. There are also alternative therapies and lifestyle remedies that attempt to manage the symptoms and provide temporary relief. These treatments are for relatively mild symptoms, yet the carpal tunnel wrist surgical procedure is still the second most common surgery in America; sometimes even the surgery is not enough and risks worsening symptoms.
