Thumb Amputee

Dennis was a defense contractor in Afghanistan in 2010 when a rocket tore through the building where he lived. His hand and shoulder were injured and his right thumb was amputated on the spot. After returning to the U.S., he tried two different prosthetic providers, but was not happy with the care he received. Later, he was evaluated at an Arm Dynamics center and was successfully fit with a custom-made functional prosthesis.

Prosthesis Details

  • Passive partial hand device with a positional thumb and an articulating thumb tip

  • Custom socket with a cushioning silicone interface

  • Custom activity-specific golf device

"I’m a very active person and for the first time since my injury, I’m wearing a prosthesis that feels comfortable. I've actually gained a much higher level of function with this thumb, and my prosthetic team even fabricated a golf device for me."
