Arthroscopy of the acromioclavicular joint

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Shoulder Arthroscopy

Background:

• The Mumford procedure (open distal clavicle resection) was historically the standard for recalcitrant acromioclavicular joint pain.
• Open surgery carries risks such as joint instability and muscle weakness.

Purpose of the Study:

• To describe the anatomy, indications, and surgical technique for arthroscopic resection of the distal clavicle.
• To present arthroscopic resection as a viable alternative to open surgery for acromioclavicular joint pain.

Main Methods:

• Review of pertinent anatomy of the acromioclavicular joint.
• Description of clinical indications for distal clavicle resection.
• Detailed explanation of arthroscopic surgical techniques, including direct/superior and indirect/subacromial approaches.

Main Results:

• Arthroscopic resection can achieve excellent results similar to open procedures.
• Minimally invasive approach avoids risks associated with open surgery, such as joint instability and muscle weakness.
• Both direct and indirect arthroscopic approaches are effective when performed systematically with measured resection.

Conclusions:

• Arthroscopic resection of the distal clavicle is an effective and safe treatment for acromioclavicular joint pain.
• This technique offers comparable outcomes to open surgery with a reduced complication profile.
• Systematic execution and precise measurement are key to successful arthroscopic distal clavicle resection.
