4. Physical examination
• Vital sign : BT 35.9 BP 127/63 PR 87 RR 20
• GA : an adult Thai man, good consciousness, deaf,
• HEENT : not pale conjunctivae, anicteric sclerea
• Heart : normal S1S2, no murmur
• Lung : equal breath sound, no adventitious sound
• Abd : soft, not tender, no palpable mass
• Ext : affected part
• Neuro : motor grade V all, sensory intact
5. Physical examination
• Affected part
– Tender at right proximal to middle clavicle area
– Stepping at right proximal to middle clavicle area
– Skin dimple seen at right proximal to middle clavicle area
– limit ROM of right shoulder due to pain
– Intact neurovascular
15. Epidemiology
• 2.6% of all fractures
• 69% in middle third
• 28% in distal third
• 2.8 – 9.3% in proximal third
• Peak incidence in children and young adults
19. Mechanism of injury
• Fall onto shoulder 87%
– Traffic accident
– sport
• Direct injury to clavicle
– Falling object
– assault
20. Classification
• Allman classification
– 3 groups based on location
• Group I : fractures of the middle third most common
• Group II : fractures of the distal third Neer classification
• Group III : fractures of the proximal third
23. Clinical presentation
• Group I
– Localized pain exacerbated by movement of arm
– Snap/cracking sensation
– Bone angulation/hematoma
• Group II
– Pain around AC joint
– Cross arm test positive
– Minimal deformity
24. Clinical presentation
• Group III
– Pain near sternoclavicular area
– Worsen by movement of shoulder and supine position
– Anteriorly protruding of medial clavicle
– Often associated with serious injury
25. Investigation
• Imaging
– Radiographs
• AP view of bilateral shoulders
– to measure clavicular shortening
• 45° cephalic tilt superior/inferior displacement
• 45° caudal tilt AP displacement
– CT
• may help evaluate displacement, shortening, comminution, articular
extension, and nonunion
• useful for medial physeal fractures and sternoclavicular injuries
31. Complication
• Malunion most common
• Nonunion (if fail to heal after 4 – 6 mo)
• Pneumothorax
• Subclavian vessels/carotid A. compression or laceration
• Brachial plexus injury
• Post-traumatic arthritis
32. Treatment
• Non-operative
– Sling immobilization
• indications
–Non-displaced Group I (middle third)
–stable Group II fractures (Type I, III, IV)
–Non-displaced Group III (medial third)
–pediatric distal clavicle fractures (skeletally immature)
33. Treatment
• Sling immobilization
– Arm sling or figure-of-eight splint
• have no differences in healing times, healing rates, and alignment at final
follow-up
– Adjust q 7 – 10 days
– After 3-4 weeks begin gentle range of motion exercises
35. Treatment
• Operative (should refer)
– open reduction internal fixation indications
• absolute
–unstable Group II fractures (Type IIA, Type IIB, Type V)
–open fracture
–displaced fracture with skin tenting
–subclavian artery or vein injury
–floating shoulder (clavicle and scapula neck fracture)
–symptomatic nonunion
–posteriorly displaced Group III fracture
–displaced Group I (middle third) with >2cm shortening
36. Treatment
• Operative
– Coracoclavicular ligament repair/reconstruct
– plate and screw fixation
• reconstruction plate
• intramedullary screw or nail fixation
• hook plate
38. Return to work and sport
• In general
– 6 – 8 weeks
• Distal clavicle fracture return to pre-injury level sooner
– 4 – 6 weeks
• Should avoid contact sport and strenuous activity until4 weeks
after clinical healing
– Required 8 – 12 weeks before returning to contact sport
– Should remove hardware before playing
