Mallet Finger

Mallet finger is a deformity at the distal end of the finger and/or thumb at the last joint. It is usually due to a rupture of the extensor tendon causing a flexion deformity at the distal interphalangeal joint. It can be associated with or without a fracture. If the finger can be passively extended to 0 degrees of extension, then the patient can be appropriately treated with a splint. Usually splint immobilization is for approximately 6 weeks in full extension. The splint must be worn full time without removal of the splint. If there is a large intraarticular fracture, then sometimes surgical intervention is warranted. This would include wiring of the fracture back into proper position and transfixion of the joint with a pin to protect the healing of the fracture for approximately 6 weeks. With only a rupture of the tendon, usually splinting is effective in most cases for long term results and proper treatment.
