Jersey Finger (zone 1 flexor injury)

Question 1

Etiology

Answer 1

rupture of flexor digitorum profundus

Question 2

SSx and complications

Answer 2

complications:
edema
adhesion
joint stiffness

• Clumsiness in tasks involving fine finger dexterity if radial 3 fingers are affected
• Decreased gripping strength in stabilizing hand tools if ulnar 2 fingers are affected

Question 3

Flexor tendon rehab program

Answer 3

splint + start passive flexion of IPJ
* Facilitate differential tendon gliding
* Prevent joint stiffness due to edema and temporary decrease of active flexion

Tenodesis → Enhance tendon gliding/ excursion without increased tension of the repaired tendon
