Finger Conditions Flashcards
Flexor Digitorum Profundus Avulsion
What is the most common digit affected?
The ring finger
Flexor Digitorum Profundus Avulsion
What is the MOI?
hyperextension stress to a flexed finger
Ex. when an athletes grab an opponents jersey
Flexor Digitorum Profundus Avulsion
What is the subjective findings?
Hx of trauma in the digit
Flexor Digitorum Profundus Avulsion
What are the objective findings?
- Testing of the isolated DIP joint flexion in all digits
- won’t be able to flex DIP
- assessment of the FDP for DIP and PIP
- tenderness in flexor tendon sheath or palm
Flexor Digitorum Profundus Avulsion
What is the common interventions?
primarily surgical
Flexor Digitorum Profundus Avulsion
What is the overall prognosis?
- Depends on the acutenes of the dx
- rapidity of surgical intervention
- level of tendon retraction
Trigger Finger
What is the MOI?
Inflammation of fingers –> thick and narrow as they cross the MCP head in the palm = painful snapping
May be idiopathic
Trigger Finger
What is the most comon structures affected?
2 flxor tendons of the finger

- long and ring finger
Trigger Finger
What population is commonly affected?
Often middle aged women
Trigger Finger
What are the subjective findings?
C/o of painful finger or catching of the finger when gripping or pinching
Trigger Finger
What are the objective findings?
- local tenderness at the base of the finger (over the tendon)
- can have crepitus or moving nodular mass
- pain by stretching into extension or resisted isometric flexion
- clicking or locking w/ active flexion
- full flexion probs limited
Trigger Finger
What is the confirming/special tests to dx?
none indicated while radiographs not needed
Trigger Finger
What are the goals of interventions?
- Reduce swelling and inflammation flexor tendon sheath
- promote smooth movement of the tendon
Trigger Finger
What are most common treatment of choice?
Corticosteroid injections into the sheath
Trigger Finger
What is the prognosis?
- improving right away is rare
- reccuring problems need to look at their work and hobbies
- surgical release is reserved for recalcitrant cases
