This design provides extension to the PIP and a mild extension effect to the MCP. Leaves the DIP completely free. The pressure is distributed by the dorsal pad. The spring can be adjusted individually. The force is approximately 2.3 N in 15 degrees of flexion.Indications: extension defect of 45 degrees or less in the PIP joint, correction of Boutonniere defect.Length in cm. The measurement is taken from the distal crease in the palm to the crease of the DIP joint. The finger should be extended during the measurement.
