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

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.
