Answer
Surgical indications include the following:
-
Complete fracture displacement [4]
-
Severe displacement causing tenting of the skin with the risk of puncture
-
Fractures with 2 cm of shortening
-
Comminuted fractures with a displaced transverse "zed" (or Z-shaped) fragment [4]
-
Neurovascular compromise
-
Displaced medial clavicular fractures with mediastinal structures at risk [5]
-
Polytrauma (with multiple fractures): To expedite rehabilitation
-
Open fractures
-
An inability to tolerate closed treatment
-
Fractures with interposed muscle
-
Established, symptomatic nonunion
-
Concomitant glenoid neck fracture (floating shoulder)

A type II distal clavicle fracture. In type IIA, both conoid and trapezoid ligaments are on the distal segment, while the proximal segment, without ligamentous attachments, is displaced.
-
A type IIB fracture of the distal clavicle. The conoid ligament is ruptured, while the trapezoid ligament remains attached to the distal segment. The proximal fragment is displaced.
