KnuckleUp MCP Extension Orthosis

Description

Available for shipping July 2025! The KnuckleUp orthoses are designed to address loss of digit extension and correction of angulation of the digits. Common applications include loss of extension secondary to radial nerve palsy and loss of extension from attritional extensor tendon ruptures. The orthosis is also indicated in extensor weakness from extensor hood attrition and subluxation related to rheumatoid arthritis. For fingers with ulnar drift, the angle of orthosis tension can be adjusted to help overcome finger deviation.
