What Causes CTS?
The Wrist Tunnel (carpus means wrist)
A fishing rod uses rings to hold the line in place. Our arms have rings (or tunnels) to hold the nerves and tendons in place.
A tight tunnel puts pressure on the nerve.
Over many years, this pressure can damage the nerve.
The tunnels in your arm hold the nerves and tendons in place. (Click for a larger image).
Some of Us Are Born with a Narrow Wrist Tunnel
It's Inherited - Current evidence suggests that carpal tunnel syndrome runs in families. Like eye color or how soon you get grey hair—it’s in the genes.
It's How You're Built - We all know that some of us are “double jointed”, which means that some of us have loose joints. And others have tight joints. It seems that some of us are born with tighter tunnels than others.
Tight Tunnel - Most CTS cases are due to tighter tunnels.
Squeezing the Median Nerve - A narrow tunnel harms the nerve over many years and decades.
People sometimes get carpal tunnel syndrome when something takes up space in the tunnel.
