Splint Patterns

Getting Started with Patterns

• The first step to making a splint is determining
  the shape and size of a persons hand.
• You will trace the shape of the hand on a piece
  of paper
• We will discuss the specifics of how to draw the
  pattern

3
Considerations

• Custom Pattern?
• Standard Pattern?
• Precut Material?
• Soft Orthosis?
• Cost of time and materials

4
Key Points to Locate

• Wrist joints
• MPs (IPs)
• Thumb web space
• Forearm length is 2/3s if included
• Width of palm

5
Dual Obliquity

• MP joints slant in ulnar direction
• Index finger - Radially MP heads are just distal
  to the Proximal Palmar Crease
• Little finger - on ulnar side, MP heads are just
  distal to the Distal Palmar Crease

6
Patterns

• Made on a dry paper towel
• Final fit can be tried with damp paper towel
• Clear plastic or bag
• For acute injury or severe deformity
• If another hand needs to be used then consider
  that the dominant hand is generally larger

7
General Outline of Pattern

• For outline, hold pen at 45 degree angle to part
  of arm you are measuring to allow for ½ sides of
  arms.
• Use a larger or smaller outline as indicated by
  size of clients
• WHEN SPANNING MULTIPLE FLEXED JOINTS THE PATTERN
  DRAWN FROM A HAND IN NEUTRAL WILL NEED TO BE
  LARGER

Radial Gutter Thumb Spica

• Place hand Pronated on flat surface
• Abduct Thumb

10

• Mark
• Wrist joints AB
• MPs digits 2 5 CD
• Radial Side of Thumb IP E
• Elbow Crease F
• Extend out 1/4 and down 1/4 for Thumb MP G
• Forearm length H
• Extend 1/2 down and out from 5th MP I

11
Wrist Cock-Up Splint

• Same position of hand for thumb spica

12

• Mark
• AB Wrist Joints
• CD MPs digits 2 and 5
• E Thumb CMC or distal wrist crease
• F Elbow Crease
• G Forearm length 2/3s
• H Extend out and down 1/2 from 5th digit
• I Lateral tip of thumb
• J Thumb web space
• When connecting J to E draw a curved thenar
  space with outermost point at the second web
  space
