In a fracture shaft humerus which of the following complication requires immediate surgery:

Indications of emergency surgery in ohopaedics: Compament syndrome Vascular injury Open injury Joint dislocation/subluxation Progressive neural injury Compound/open injury: It is relatively lesser emergency as compared to vascular injury. In case of open injuries we can still wait for up to 12 to 24 hours.

Comminuted fracture: It is not an emergent indication for surgery.
