AOSR iPad app will be discontinued

Due to its marginal use and high maintenance cost, the AOSR iPad app will be discontinued in August. Instead you may access the AOSR through the iPhone/Android app, or a web browser.

To use the AOSR without the app on your iPad:

  1. Go to
  2. If preferred, you can now choose to use the desktop version on your iPad at the bottom of the screen
  3. If you want an AO Surgey Reference icon on your iPad, just add a link button to your home screen, here is how to do it

Posterior approach i

Posterior approach

Generally extra articular fractures of the scapular neck, posterior rim, and posterior articular segments are approached posteriorly.

Arthroscopic entry points i

Arthroscopic entry points

An arthroscope is of use only if one is dealing with a fracture that involves the articular surfaces and can be used only if the patient is in the beach chair position.

Deltopectoral approach i

Deltopectoral approach

The (anterior) deltopectoral approach can be used for almost any shoulder fracture treatment and is often the preferred approach, especially in anterior glenoid fractures.

This approach is also highly recommended for extensile exposures.

Superior to acromion i

Posterior approach

The superior extension of the anterior
deltoid split can be used for treatments of simple acromion fractures and nailing of proximal humeral fractures.

Sabercut approach i

 Sabercut approach

The superior or saber cut approach is a straight incision running directly from front to back.

It is used to expose the AC-joint and the acromion.
