Superior acromial anterior to posterior approach (Sabercut approach)

The superior acromial anterior to posterior approach (or Sabercut approach) is a straight incision running directly from front to back.

It is used to expose the acromion.

This approach can be performed to treat proximal periprosthetic fractures around reverse and anatomic prostheses.

A reverse prosthesis has been used as an example in the rest of this approach.

Anatomical landmarks for the superior approach are:

A) The acromioclavicular joint

B) The posterior border of the acromion

Both landmarks can be palpated easily.

Begin anterior to the acromioclavicular joint, and end at the posterolateral corner of the acromion.

If indicated, this incision can be extended into:

• The deltopectoral approach
• The posterior approach to the humerus
• The extended superior scapular approach
• The transverse clavicular approach

A partial detachment of the deltoid muscle and trapezius may be necessary to expose the fracture.

Reattach the released muscles. The subcutaneous fascia and the skin are closed in layers.
