| The PHOENIX
WRIST UNIT package includes: wrist unit;
3 binding head screws with thumb nuts; 10
adjustable nylon fasteners; and a hex wrench.
Additional splint supplies, needed but not
included, are: low temperature thermoplastic (1/16"
thick); strap material; and rubber bands or
springs with variable tensions. |
|
|
Set
screws at the lateral bars, allow 1/2 inch
proximal-distal adjustment.
|
|
|
| The distal bar is
reversible to allow fitting to right or left
hands. Lateral adjustment at the "T" is
provided to accommodate extreme radial or ulnar
deviation. |
|
|
| |
|
|
|
|
|
| Step #1:
A forearm gauntlet pattern is drawn. It extends
approximately 2/3 the length of the forearm, but
measures no less than 5". It rests proximal
to the radial and ulnar styloids. Circumference
measurement allows approximately 1" overlap. |
|
Step #2: The
pattern is cut from 1/16" thermoplastic,
heated, then wrapped around the forearm. The
thermoplastic is placed, not pressed, to lightly
adhere to itself. Proximal and distal edges are
slightly flared. Approximately 45 degree
forearm pronation is suggested as the
position for fitting the guantlet. Straps are
attached. |
| |
|
|
|
|
|
| Step #3: A
rectangular pattern is cut for the palmar splint.
The width equals the circumference of the palm at
the palmar crease. The length equals the distance
from the flexion crease to the hook of the
hamate. |
|
Step #4: The
pattern is cut from 1/16" thermoplastic,
heated, then wrapped around the palm. The
thermoplastic lightly adheres at the dorsum of
the hand and holds the cuff in position as the
edges are carefully rolled to fit the thenar and
MP flexion creases. |
| |
|
|
|
|
|
| Step #5:
The cuff is marked for trimming and for location
holes to be punched for nylon fasteners. |
|
Step #6:
After the gauntlet and palmar cuff are formed,
the PHOENIX WRIST UNIT is
positioned volarly to align the hinge with the
axis of motion. The guantlet is marked to locate
holes to be punched for attaching the outrigger. |
| |
|
|
|
|
|
| Step #7: A
hole is punched at the dorsal-proximal edge of
the splint. A thumb nut is then attached to
anchor the rubber bands. Two holes are punched on
the volar side of the gauntlet and the outrigger
is attached by thumb nuts. |
|
Step #8: Holes
are punched in the cuff and nylon fasteners are
threaded through. |
| |
|
|
|
|
|
| Step #9:
The fasteners are looped and adjusted to the
desired length. The outrigger length is adjusted. |
|
Step #10:
The two movable collars are positioned to guide
the nylon loops. The excess line is cut off. |
