Abstract:

BACKGROUND: How to reconstruct the rostral clavicular ligament to make it more suitable for the biomechanical characteristics of acromioclavicular joint and do not need to remove the internal fixator is a problem that scholars have been thinking about.

OBJECTIVE: To explore the clinical effect of two anchors to reconstruct coracoclavicular ligament in treatment of Tossy Ⅲ acromioclavicular joint dislocation.
METHODS: Eighteen patients with Tossy Ⅲ acromioclavicular joint dislocation were treated with two anchors to reconstruct coracoclavicular ligament from January 2012 to July 2016. All patients were followed up for 1 year. Acromioclavicular clavicle end gap was measured using X-ray films before treatment, 1 week, 2 months and 1 year after treatment. Shoulder joint function was evaluated by the Neer scoring system before treatment and 1 year after treatment. 
RESULTS AND CONCLUSION: (1) Acromioclavicular clavicle end gap significantly reduced between the preoperation and 1 week after surgery (P < 0.05). Acromioclavicular clavicle end gap significantly enlarged between 1 week and 2 months after surgery (P < 0.05). There was not statistically significant difference in the gap between 2 months after surgery and 1 year after surgery (P > 0.05). There was not statistically significant difference in the gap between injured and uninjured sides 2 months after surgery (P > 0.05). There was not statistically significant difference in the gap between injured and uninjured sides 1 year after surgery (P > 0.05). (2) Neer scores significantly increased 1 year after surgery compared with that before surgery (P < 0.05). (3) These findings confirmed that coracoclavicular ligament reconstruction using two 5 mm-diameter anchors in treatment of Tossy Ⅲ acromioclavicular joint dislocation can obtain satisfactory effect.
