Biomechanical comparison of postoperative stability in use of three kinds of endobutton technique for coracoclavicular ligament reconstruction
Objective To investigate the biomechanical differences of postoperative stability in use of single，double and triple Endobutton techniques for coracoclavicular ligament reconstruction. Method 40 fresh frozen shoulder specimens were randomly divided into 4 groups,10 in each group. Tissues in the shoulder specimens were dissected away to only preserve the scapula-coracoclavicular ligament-clavicle structure. The first 3 groups were the experimental group (group 1, group 2 and group 3). The coracoclavicular ligaments were disruputed, and then we used three kinds of Endobutton techniques for the reconstruction of coracoclavicular ligament. The fourth group served as the control group (group 4). The original coracoclavicular ligament was reserved. And then,we continued the vertical biomechanical tensile test, and the maximum strength causing the reconstruction failure was recorded. Result When thecoracoclavicular structure in each group was destroyed，the tensile strength were as follows： group 1（597.10±65.58）N，group 2（750.67±51.00）N，group 3（774.82±64.94） N and group 4（645.44±43.37）N. The maximum tensile strength of group 1 was slightly lower than that of group 4 (P>0.05); the maximum tensile strength of group 2 and group 3 was significantly higher than that of group 4 (P<0.05); the maximum tensile strength of group 3 was slightly higher than that of group 2 (P>0.05). Conclusion Three kinds of Endobutton technique all could be used for coracoclavicular ligament reconstruction. The vertical stability of the double Endobutton technique and thetriple Endobutton technique were superior to the single Endobutton technique. The vertical stability of the double Endobutton technique and the triple Endobutton technique was similar.
