"type I: FDP tendon is avulsed without fracture and retracted to the palm"
"type II: FDP retracts to the level of the proximal interphalangeal joint"
"type III: large avulsion fracture limits retraction to the level of the distal interphalangeal (DIP) joint (the avulsed bony distal fragments become caught in the A4 pulley, preventing further retraction)"
"type IV: combined bony avulsion and tendon avulsion from the bony fragment ("double avulsion” with subsequent retraction of the tendon, usually into the palm)"
"type V: ruptured tendon with bone avulsion with bony comminution of the remaining distal phalanx"
"type I: tendon should be repaired with prompt surgical treatment within 7 to 10 days"
"type II: tendon should be repaired within several weeks for optimal outcome"
"type III: tendon should be repaired within several weeks for optimal outcome"
"type IV: if tendon separated from fracture fragment, fracture should be first fixed then the tendon is reattached as for type I/II injuries"
"type V: stability of the DIP joint should be obtained before fixation of the avulsed osseous fragment 1"
"type I: tendon should be repaired with prompt surgical treatment within 7 to 10 days"
"type II: tendon should be repaired within several weeks for optimal outcome"
"type III: tendon should be repaired within several weeks for optimal outcome"
