Anterior Approach to the Clavicle
Anterior Approach to the Clavicle can be used in any type of clavicle midshaft fractures for anterior or superior clavicle plating.
Clavicle anterior approach indications include the following:
1. Open reduction and internal fixation of fractures
2. Reconstruction of the sternoclavicular and the acromioclavicular joints in case of dislocation
3. Drainage of sepsis
4. Biopsy and excision of tumors
5. Osteotomy for malunion
The brachial plexus and subacromial vessels can also be approached via this surgical approach, where osteotomy of the clavicle is required.
The clavicle fractures most often resulting from a direct blow or a fall on an outstretched arm, it’s one of the most frequently fractures in the body.

Position of the Patient
The patient is placed supine on the operating table. Break the table and elevate the head end, so as to elevate the shoulder area. Place a sandbag between the medial border of the scapula and the spine.
Landmarks and Incision
The sternal notch is the most medial landmark of the incision.
Make an incision following the S-shaped clavicular anatomy, beginning from the medial end.
Internervous plane
There is no internervous plane for clavicle anterior approach because the approach is directly onto the subcutaneous surface of the clavicle.
Superficial dissection
Deepen the skin incision through the platysma to reach the subcutaneous surface of the clavicle.
Deep dissection
Gently strip soft tissues off the subcutaneous surface of the clavicle in an epi-periosteal plane.
Approach Extension
This approach can be enlarged longitudinally along the whole length of the clavicle as required.
The approach can be extended distally into the anterolateral approach to the proximal humerus and
mid shaft of the humerus using the deltopectoral interval.
Dangers
The structures at risks in anterior approach to the clavicle are:
- Nerves: The brachial plexus.
- Vessels: The subacromial artery and vein.
