Mallet Finger
Absence of a fracture does NOT exclude Mallet finger, the extension function of the DIP joint needs to be clinically assessed. Here's a quick summary.
• Finger deformity caused by disruption (may be bony or tendinous) of the terminal extensor tendon distal to the DIP joint
• Mechanism: Hyperflexion injury with axial load (ball striking fingertip)
• Exam: Swollen and tender DIP joint that is fixed in flexion due to inability to extend
• Possible associated injuries: Avulsion fracture
• ED Management: Pain control, immobilize
• Splint: Extension splint of DIP joint, maintain free movement of PIP joint
• Ortho consult: No
• Disposition: Discharge with orthpedic follow-up within 1 week
