Description

AC Joint Repair Button (Suspensory Fixation System):
nAn AC joint repair button is an implant used in orthopedic surgery to stabilize the acromioclavicular (AC) joint, usually after an AC joint dislocation (commonly Rockwood type III–V).
n
n🔹 Design & Structure:
n
nConsists of two small metallic or composite buttons connected with a high-strength suture loop (like FiberWire or similar).
n
nOne button is placed on the superior clavicle, and the other passes through the coracoid process, securing the clavicle back to its anatomical position.
n
n🔹 Function:
n
nActs like an internal brace, holding the clavicle and coracoid together.
n
nAllows for biological healing of torn ligaments (coracoclavicular ligaments).
n
nProvides strong fixation while minimizing hardware irritation compared to plates or screws.
n
n🔹 Advantages:
n
nMinimally invasive (arthroscopic or mini-open).
n
nPreserves normal anatomy.
n
nEarly mobilization possible.
n
nReduces risk of hardware removal (unlike hook plates).
