Transverse fracture: more stable, less shortening risk, no periosteal envelope stripping
Extension block splinting:
．for base fracture
．for p2 base, intraarticular involvement < 40 degree
．initial 60 degree flexion, then deduct 10 degree/ week
．maintain congruent reduction
Condylar fx of the head
．close: 2 k-wire, 1 transverse, 1 oblique
．open: consider lag screw
Unstable shaft fracture
．1.2 mm K-wire
．cross pinning at fracture site: highly unstable
．interfragmentary lag screw
．mini-plate
Partial articular base fracture
．extension block pinning
Author preferred treatment
．shaft: splinting for stable, crossed pinning for unstable
．dorsal base: extensive block pinning 3 weeks. ORIF with 1.3 mm lag screw for delayed treatment
