Introduction Clinical definition fracture of the clavicle classified based on location (medial third, middle third, and lateral third) middle third fracture is most common Epidemiology demographics 4-10% of adult fractures more common in children and the elderly (> 70 years of age) Pathogenesis most commonly from direct fall on the shoulder (adults and children) direct blow to the lateral aspect of the shoulder birth trauma (newborns) Associated conditions brachial nerve palsies Prognosis most fractures heal well Presentation Symptoms shoulder pain that worsens with any movement Physical exam swelling, erythema, and deformity of clavicle tenderness to palpation worse with passive and active movement tenting of skin overlying fracture indicates skin necrosis and open fracture rule out associated injuries to neurovasculature thorough distal pulse and neurologic exam Imaging Radiographs indication for all patients recommend views anteroposterior and clavicle view findings clavicular fracture Studies Making the diagnosis based on clinical presentation and imaging Differential Sternal fracture distinguishing factor no clavicular fracture seen on imaging sternal fracture seen on imaging Bruise distinguishing factor no fractures on imaging Treatment Management approach typically treated conservatively with a sling or brace Conservative immobilization indication for most patients modalities simple arm sling or figure-of-eight sling Medical nonsteroidal anti-inflammatory drugs indication pain management Operative surgical treatment indication fractures at risk for malunion open fracture skin tenting on exam unstable fractures surgery open reduction internal fixation Complications Cosmetic deformity of shoulder Limited mobility of shoulder
