Abstract:

BACKGROUND: Clinical studies demonstrated that allogenic tendon can not result in systemic immunological reaction following sterilization and profound hypothermia, and the local reaction is also slightly, thus, it has no obviously difference in treating knee ligaments injuries using allogenic or autologous tendons.
OBJECTIVE: To evaluate the effects on clinical application coracoclavicular ligament with allogenic tendon for treating dislocation of acromino-clavicular joint and distal clavicular fracture.
METHODS: Totally 23 patients, including 17 males and 6 females, aged 19-45 years, mean aged 30.4 years were selected. There were 18 cases with Tossy-Ⅲ acromino-clavicular joint dislocation and 5 cases with Neer-Ⅱdistal clavicular fracture. Fifteen patients at right sides and 8 at left sides, all of them were fresh dislocation or fracture. One patient suffered from acromino-clavicular joint dislocation combined with brachial plexus strain injury. The trapezoid ligament and conoid ligament were reconstructed using allogenic tendon through 2 drilled hole within the clavicular distal end and inferior part of coracoid process. 
RESULTS AND CONCLUSION: All patients were followed up from 12 to 26 months, with an average of 16.5 months. All the incisions were healed primarily, and the union of distal claviclar fracture of 5 cases took place and healed within 4 months without malunion. There were 19 cases excellent and 4 cases good according to the criterion of Karlsson. No biocompatibility, systematic or local immunological reaction occurred. The reconstruction of the coracoclavicular ligament with allogenic tendon is characterized by simple operation, minimal trauma and satisfactory results.
