Orthopaedic Hand Trauma CH32 (1)


SECTION 3  | Tendon Injuries

■ ■ Acute open mallet finger— For a purely tendinous mallet, a combina- tion of irrigation and debridement with primary tendinous repair and primary closure is indicated. If primary repair of the extensor tendon cannot be achieved, the tendon may be sutured incorporating the skin (tenodermodesis) or can be reconstructed with tendon graft in a primary or delayed fashion. The patient is then splinted in DIP joint extension postoperatively.


CRPP vs ORIF for distal phalangeal volar subluxation, inability to tolerate splinting, >50% of articular surface involved, or >2mm of articular step-off


Splinting for 6-8 wk for acute (less than 12 wk) soft tissue injury or non- displaced bony mallet injury.

2-4 wk of nighttime splinting


Mallet Injury

Primary Operative Repair



Antibiotics, irrigation/ debridement, and splinting
