Splint in antideformity and don't move a finger!
3 main deformities:
Mallet Finger
Boutonniere's
Swan Neck
Mallet Finger
Your DIP is flexed.

Boutinniere deformity
flexion of PIP and hyperextension of DIP

(Think of pressing a button)

Swan neck deformity
hyperextension of PIP joint and flexion of DIP joint

Mallet Finger effects the _____. B/S effect both ____ and ____ but ____ is more of a concern/focus.
DIP
DIP and PIP, PIP
Stages of Healing (I know this)
*special note:
bones and tendons healing: 6-8 weeks (same as bones)
Intrinsic plus/antideformity position (I know this)
The opposite of the typical position of deformity to prevent deformity.
This movement is performed by your lumbricals, which are some of the intrinsic muscles of the hand.
Lateral collateral ligaments and volar plates...
will become contracted/shortened if left in flexion too long.
Overall:
-Spint it back into:
-Wear day and night for:
-Because of long interrupted wear schedule:
-antideformity (intrinsic plus) position, serial splint if needed.
-6-8 weeks, then gentle ROM when approved.
-We want to make sure the splint doesn't apply too much pressure: look for blanching.
These splints will be worn for6-8 weeks without removalWhat do we do for mallet finger?Splint into extension, or slight hyperextension at DIP. (It is caused by damage to extensor tendon)What do we do for the Boutonniere deformity?Use oval 8 splint. Focus on PIP- hold the PIP in extension, DIP should behave itself after that. (buttons- the inch worm)What do we do for swan neck?focus on slight flexion (near full extension) of PIP, DIP should be fine. Want to encourage active flexion of PIP joint, oval 8 splint good for this.Oval 8 will allow for...standard flexion for swan neck (we want this) but prevents extension.There are some other types of joint specific injuries but the principal is the same. Immobilize in an antideformity position to promote healing until the physician clears for ROM.Again, they will be wearing these splints for a straight 6-8 weeks. You could give them two, BUT:hand needs to be flat on table when changing. Be very careful. As soon as its not, you have undone all the process you have made.
