Proximal Humerus Fracture Plating Through the Extended Anterolateral Approach

Area of Science:

• Orthopedic Surgery
• Traumatology
• Surgical Anatomy

Background:

• Proximal humerus fractures are common orthopedic injuries.
• Traditional deltopectoral approach has limitations for fracture reduction and locked plating.
• Need for improved surgical techniques in fracture fixation.

Purpose of the Study:

• To evaluate the anterolateral acromial approach for proximal humerus fracture fixation.
• To compare its advantages over the deltopectoral approach.
• To detail the surgical technique and anatomical considerations.

Main Methods:

• Utilizing the intermuscular plane between anterior and middle deltoid heads.
• Identifying and preserving the axillary nerve.
• Performing fracture reduction and locked plating.
• Assessing direct access to greater and lesser tuberosities.

Main Results:

• The anterolateral acromial approach facilitates direct access to both tuberosities.
• Humeral head fragments offer excellent surfaces for manipulation.
• Reduced risk to extraosseous soft tissue attachments.
• Overcomes disadvantages of the deltopectoral approach.

Conclusions:

• The anterolateral acromial approach is a viable and advantageous technique for proximal humerus fracture fixation.
• It provides excellent visualization and manipulation of fracture fragments.
• This approach enhances safety and efficacy in managing complex fractures.
