Treatment of Mallet Finger

May 25th, 2007

A mallet finger describes loss of the extensor tendon insertion on the distal phalanx--either due to avulsion fracture, or tendon avulsion alone. The distal joint droops, thus the appearance of a "mallet". Historically, a high complication rate has been associated with operative intervention, thus splints have been used.

During your appontment I will check an xray to rule out fracture. A displaced fracture and volar subluxation of the phalanx may neccessitate surgery, otherwise a splint of the DIP joint will be worn for 8 weeks. Since this is a bit of an inconvenience, to say the least, I have begun offering the placement of a temporary pin for 8 weeks--to obviate the need for a splint. The early outcomes have been quite good--so this option, as well as the splint, will be discussed with you during your appointment.

The use of a splint does allow the remainder of the involved finger to flex to prevent stiffness
