Mallet and Jersey Finger Quiz

What is the primary cause of Mallet Finger?

• Forced flexion of the DIP joint

• Forced hyperextension of the DIP joint

• Forced flexion of the PIP joint

• Crush injury to the DIP joint

Which structure is injured in Mallet Finger?

• Flexor digitorum profundus

• Extensor digitorum tendon

• Flexor pollicis longus

• Central slip

The characteristic deformity in Mallet Finger is:

• Fixed flexion at the PIP joint

• Hyperextension of the DIP joint

• Drooping of the DIP joint

• Loss of flexion at the PIP joint

The recommended treatment for an acute Mallet Finger without a bony avulsion is:

• Surgical fixation

• DIP joint splinting in extension

• Immobilization of PIP joint

• Traction device

A Mallet Finger injury associated with a large bony fragment may require:

• Only conservative splinting

• Open reduction and internal fixation (ORIF)

• Amputation of the finger

• Arthroscopic repair

Jersey Finger is caused by:

• Hyperextension of the DIP joint

• Sudden forced flexion of the DIP joint

• Forced hyperextension of the PIP joint

• Sudden forced extension of the DIP joint

The injured tendon in Jersey Finger is:

• Flexor digitorum profundus (FDP)

• Flexor digitorum superficialis (FDS)

• Extensor digitorum tendon

• Central slip

Which finger is most commonly affected in Jersey Finger?

• Thumb

• Index finger

• Middle finger

• Ring finger

What is the primary clinical feature of Jersey Finger?

• Inability to extend the DIP joint

• Inability to flex the DIP joint

• Swelling of the PIP joint

• Hyperextension deformity at the DIP joint

The definitive treatment for Jersey Finger is:

• Conservative management with splinting

• Surgical repair of the FDP tendon

• Corticosteroid injections

• Physical therapy alone
