Findings
- Acute middle third left clavicle fracture with one shaft width inferior displacement of the distal fracture fragment and apex superior angulation
- Mild angulation at the left sternoclavicular joint without evidence of dislocation
Diagnosis
Clavicle fracture
Sample Report
Acute middle third left clavicle fracture with one shaft width inferior displacement of the distal fracture fragment and apex superior angulation.
Mild angulation at the left sternoclavicular joint without evidence of dislocation.
Normal left acromioclavicular joint alignment.
No widening of the coracoclavicular distance.
Discussion
- The clavicle most commonly fractures at the junction of the middle and lateral thirds, in between attachments of the sternocleidomastoid muscle medially and coracoclavicular ligament laterally
- When the fracture is complete, the medial fragment is typically pulled superiorly (and posteriorly) by the sternocleidomastoid muscle while the lateral fragment is pulled inferiorly (and anteriorly) by the weight of the arm
- Always look for associated acromioclavicular joint malalignment or widening of the coracoclavicular distance (normal measurement < 13 mm)
