A Novel Relative Motion Splint Fabrication Technique Using Low-cost and Readily Available Materials

Summary: This article described the fabrication and clinical application of a simple relative motion extension orthosis constructed using readily accessible materials such as a wooden tongue depressor, an aluminum strip, and a cohesive bandage. Initially developed to facilitate early active mobilization following extensor tendon repairs, the relative motion extension orthosis is applied by positioning the metacarpophalangeal joint of the injured finger 15–20 degrees more extended relative to the adjacent fingers. The proposed orthosis, produced with low-cost and easily obtainable materials, is considered an effective and practical option for implementing early active mobilization protocols, particularly in settings with limited resources.
