What is mallet finger
·
Mallet finger refers to a
condition in which the end joint of a finger bends but will not straighten by
itself. In this situation, the joint can be pushed straight but will not
hold that position on its own.
·
It is condition, where there is
an interruption of the extensor tendon mechanism at the DIPJ
Causes:
1.
The mechanism which straightens
the end joint has been disrupted. This usually happens when the tip of the
finger is pushed down while the person is trying to straighten their finger
2.
The tendon which pulls on the
end bone to straighten the finger pulls one way, and the force on the end of
the fingertip pulls the other way, and something comes apart in between. Often,
the tendon tears away from its attachment to the bone:
3.
Sometimes, the tendon comes off
with a piece of bone attached, In worse cases, the tendon
comes off with a fairly large piece of bone, which can make the rest of the
joint slide out of alignment. Fortunately, that is not very common
Rehab Management
·
Patient education
·
Consent
·
Splinting
·
ROM exercise
Protocol of mallet splint
·
Continual wear of splint for
4-6 weeks
·
For chronic injury allow splint
for 8 weeks.
·
No active or passive flexion
for DIPJ
·
Allow and maintain movement for
PIPJ and MCPJ.
·
Restart counting the splinting
weeks, if the splint suddenly slip out from the DIPJ.
4-6 weeks:
·
Check for extensor lag after 4
weeks, and discontinue wear if no extensor lag
·
Continue wear if there is
extensor lag for another 2 weeks.
·
Allow for ROM exs, but need to
be worn during night.
6-8 weeks:
·
Blocking exs for DIPJ gently
and gradually.
·
Splint need to be worn at nite
·
IF there is extensor lag after
ROM exs daytime, continue wearing splint daytime and remove for exercise only.
