Table 3 Advantages and limitations of the technique

Advantages

Double-bundle titanium cable is approximately at the coracoclavicular ligament footprint on the clavicle.

Double-bundle titanium cable fixation is simulated the trapeze ligament and the pyramidal ligament, relax the coracoclavicular ligament and allow it to be repaired.

Anatomic AC reduction is provided.

The guide passes across the coracoid process without the coracoid process being exposed.

A good acromioclavicular joint reduction

Early reconstruction is better than late reconstruction.

A more stable reduction is provided with less failure than repair.

The two holes are drilled at anatomic sites of the native coracoclavicular ligament attachments (2cm, 4cm).

The holes are less than 3 mm to avoid fracture of the clavicle.

The technique is simple and inexpensive.

The technique avoids secondary surgery.

Limitations

Performed for acute cases, we have no experience with chronic cases.

For BMI>30 patients, early weight-bearing shoulder motion is not suggested.

Coracoid fracture is a contraindication.

Bone tunnel enlargement and reduction loss

The sample size is not large enough in general.

The current study is prospective, not in a RCT. Need larger sample controlled trials
