A 28-year-old male sustains a laceration to the dorsal aspect of his left hand during an assault as shown in Figure A. He is unable to actively extend his ring finger. He undergoes primary repair of the injured structure and is placed into the relative motion splint (yoke splint) shown in figure B. All of the following are benefits of this splint when compared to full-time extension splinting or dynamic splinting, EXCEPT:
Interferes less with activities of daily living
Better at limiting motion of the digit
Decreased risk of adhesions
Allows more range of motion of adjacent digits
Higher patient compliance with therapy

A patient sustains an acute, closed injury to his index finger. The clinical appearance of the finger is shown in Figure A. The patient is asked to extend the finger against resistance, with the PIP joint in 90 degrees of flexion. You note that PIP joint extension was weak, with hyperextension and restricted passive flexion of the DIP joint. When planning to treat this injury non-operatively which active joint motion is encouraged?
