Anterolateral approach

This incision is placed between the clavicular part (1) and acromial part (2) of the deltoid muscle, as illustrated.

Indications

The anterolateral (acromial) approach (Mackenzie) can be used for various treatments of proximal humeral fractures.
It is especially useful for nailing and osteosynthesis of fractures of the greater tuberosity (A1 fractures). Its is also recommended for minimally invasive plate osteosynthesis (MIPO).

This incision is placed between the clavicular part (1) and acromial part (2) of the deltoid muscle, as illustrated.

Depending on the fracture morphology and foreseen osteosynthesis the extensions of the skin incision may vary but may not extend more than 5 cm distally to the acromion, to protect the axillary nerve.
