Acromioclavicular dislocation

• More common in males and athletes

• Mechanism: direct blow to the shoulder (often sustained while falling onto the shoulder)

• Patient presents for shoulder pain, especially over the AC joint

• Xray is needed to confirm the diagnosis (AP bilateral, axillary lateral, and Zenca View)

• Rockwood classification

  • Type 1 and 2 : conservative treatment: sling + physiotherapie

Surgical intervention can be

• Reduction with botton suture under arthroscopy

• Mini-invasive reduction on achor

• Hook plate

For chronic cases, and since ligament cicatrisation is impossible, we should perform ligament reconstruction

• Weaver-Dunn procedure (weak alone)

• Complex ligamentoplasty with autograft.
