Clavicle Fracture Classification

$Allman Classification of clavicle shaft fracture$	Allman Classification (Allman FL, JBJS 49A;774:1967) Group I-middle 1/3=69%-85% Group II-lateral 1/3=12%-28%: See Distal Clavicle Fracture. Group III-medial 1/3=3%-6%
$Type I Clavicle shaft fracture xray$	Group I - Middle 1/3 Clavicle Fracture 69%-85% of clavicle fractures. 0.13%-13% non-op nonunion rate overall Generally treated non-oeratively No difference between sling and figure-8 (Stanly, Injury 19;162:1988) Closed reduction not helpful (Hill, JBJS 79B;537:1997) 31% of non-op patients report shoulder weakness, fatigue, paresthesias and asymmetry. Shortening >18 mm in males or >14 mm in females is associated unsatisfactory result. (Lazarides S, JSES 2006;15:191) Operative indications=open fx, NVI, displaced fx with impending skin compromise, shortening >20mm, significant comminution, scapulothoracic dissociation. Consider for neurologic disorders, floating shoulder, bilateral fx, cosmesis, ipsiliateral UE fx. See Clavicle Fx ORIF Technique.
$Distal clavicle fracture classification$	Group II - Lateral Clavicle Fracture Fracture in lateral 1/3 of the clavicle 12%-28% of clavicle fractures See Distal Clavicle Fracture.
$Medial clavicle fracture xray$	Group III-Medial Clavicle Fracture Fracture in the medial 1/3 of clavicle 3%-6% of clavicle fractures
