Coracoid fracture as a complication of surgical treatment by coracoclavicular tape fixation. A case report.

In a 22-year-old man surgically treated for acromioclavicular dislocation, coracoid fracture was caused by bone failure at the Mersaline loop. The addition of bony erosion between the two drill holes in the clavicle caused the tape to loosen and the deformity to recur. Postoperative infection may also have played a role in causing the coracoid fracture. When tape is used, it should be passed around the clavicle, not through it. If the deformity recurs, coracoid fracture should be suspected.
