There are many surgical procedures on patients with type 5 of the acromioclavicle joint separation classified by Rockwoods criteria. The results of the surgical procedures were satisfactory. However, these procedures are not reconstructing the anatomical coracoclavicle ligaments. In this study, we try to reconstruct the conoid and trapezoid ligament, which is composed of the coracoclavicle ligaments, using the palmaris longus with end buttons. I reviewed the postoperative results on the sixteen patients that had the reconstruction of the anatomical coracoclavicle ligaments more than six months postoperative. There were 16 patients (15 males, one female), and their ages at the time of treatment ranged from 19 to 74 years old (mean: 38.6 years old). The waiting period to the surgical procedure was 9 to 30 days (mean: 16.3 days). Pain, including night pain and motion pain, was not noted in every patient. The disturbance of range of motion in the shoulder joint was recovered in only one month postoperatively. On the radiographic evaluation, in 5 patients subluxation remained and in only one patient dislocation of the acromioclavivle joint remained, but the other 10 patients kept the reducted position in that joint at the final consultation. Despite the demerit of the excision of the palmaris longus, the results of our procedure were satisfactory.
