抄録

In one of the reconstruction surgeries for acromio-clavicular dislocation which is represented by Weaber's procedure, the coraco-acromial ligament is detached at the acromial end and transfered to the clavicle for reconstructing the damaged coraco-clavicular ligament. The procedure seems to be biomechanically reasonable in respect with the direction of the ligamentous course. However, the coraco-acromial ligament is thin compared to the coracoclavicular ligament, and it is uncertain whether the former is strong enough to compensate the loss of the latter. In the present study we performed a tension study of the coracoacromial ligament, the coraco-clavicular ligament and the acromio-clavicular ligament in five shoulders obtained from four fresh cadavers (13-68, average 43.3 years of age). Each ligament was prepared in the form of a bone-ligament-bone complex and the ultimate failing strength (maxmum tolerable load) was obtained for each ligament using an Instron universal testing instrument.<BR>The maximum loads tolerated were 20.8-44.7 (average 31.0) kgf for the coraco-acromial ligament,53.2-85.9 (average 64.5) kgf for the coraco-clavicular ligament and 46.7-79.2 (average 59.1) kgf for the acromio-claviclar ligament. The coraco-acromial ligamnt failed with only half the force compared to the coraco-clavicular ligament. Clinically, we suggest that the procedure should be carefully applied, especially in the cases of athletes and heavy laborers.
