DYNAMIC MP EXTENSION SPLINT FABRICATION USING THE

SINGLE PHOENIX OUTRIGGER PATENTED

The SINGLE PHOENIX OUTRIGGER package includes: Five dorsal wire supports; five adjustable wheels; a 5/64" hex wrench; five finger loops with nylon line attached; and five rubber band anchor posts.

Additional supplies needed but not included are: low temperature thermoplastic; strap materials; and rubber bands or springs.



FABRICATION OF THE THERMOPLASTIC BASE

STEP #1: Cut and form a dorsal splint pattern.

STEP #2: The arm is wrapped with gauze or tube stockinette. Additional padding is placed over the distal ulna.

 

STEP #3: The wrist is held at neutral or slight extension.

STEP #4: As the splint is formed, care is taken to maintain the distal transverse arch.

 



ATTACHMENT of SINGLE PHOENIX OUTRIGGER

STEP #5: The palmar bar is molded proximal to the palmar crease so that full MP flexion is possible. Care is taken not to bond the loose end of the palmar bar to the splint.

STEP #6: The Single Phoenix Outrigger is positioned over the midpoint of the selected proximal phalanx (it is helpful if the outrigger wire base is first heated with a heat gun, so upon contact with the thermoplastic, the wire embeds itself).

 

ATTACHMENT of SINGLE PHOENIX OUTRIGGER

STEP #7: A layer of thermoplastic is bonded over the outrigger wire base.  Rivets may be used to reinforce the bond.  A hole is made at the proximal portion of the dorsal splint to attach the rubber band post OR thumb nuts (sold separately) may be used to attach the Outrigger.

STEP #8 The nylon line of the finger loop is folded (near the thick portion) and threaded through the wheel.


ADJUSTMENT of SINGLE PHOENIX OUTRIGGER

STEP #9: Straps are attached at the proximal and wrist portions of the splint as well as at the palmar bar. A rubber band (spring) is attached to the thick center part of the nylon finger sling line (if the thick part of the line is bent in half between your thumb and index finger, it will hold a crease to center the rubber band).

STEP #10: The hex wrench is used to loosen the wheel set screw allowing adjustment both proximal-distal and radial-ulnar. The selected finger is placed in the loop, the rubber band attached to the post and the wheel adjusted for proper leader line alignment (a right angle to the digit).
