Definition

Knuckle Bender Splint is a finger flexion splint designed for use by individuals with disabilities of the fingers. Splint flexes the finger joints (all digits) without blocking IP or wrist motion. The strength of the rubber band determines traction force. This splint simultaneously flexes the metacarpal phalangeal (MCP) joints of all digits without blocking interphalangeal (IP) or wrist motion. Constructed of stainless steel with felt pads, the splint uses the strength of the rubber bands to determine traction force.
