Failure of coracoclavicular ligament reconstruction associated with medial bone tunnel placement

Recently published results showed a significant association between the placement of the medial bone tunnel with radiographic failure in patients who underwent anatomic coracoclavicular ligament reconstruction.
Researchers identified 38 patients in the military’s electronic medical records who underwent 39 anatomic coracoclavicular reconstructions between 2000 and 2013. Researchers defined radiographic failure as 6 mm of superior clavicle displacement as evidenced on immediate postoperative films.
Results showed 20 radiographic failures, with an average conoid tunnel ratio of 0.27. When researchers compared conoid tunnel ratios with a reference ratio of 0.20 to 0.25, they noted a statistically significant increased risk of failure with lateralization greater than 0.20 or with medialization of 0.251 to 0.30 or greater. Although medialization of the trapezoid position greater than 0.16 was also significant for failure, the significant findings did not correlate with symptoms or ability to return to duty, according to results. – by Casey Tingle
