  • Coracoclavicular ligament is main restraint to superior instability of the distal clavicle. Coracoacromial ligament, extensor tendon of toe, palmaris longus tendon, and Dacron tape have been used to reconstruct coracoclavicular ligament. We used semitedinosus tendon to reconstruct coracoclavicular ligament. The semitendinosus tendon was harvested as a usual fashion. After the distal clavicle and coracoid process were exposed, a hole of six millimeter diameter was made on the center of whole thickness of the distal clavicle. A malleolar screw was fixed from distal clavicle to coracoid process to maintain the reduced position of the acromioclavicular joint. The leading suture of tendon graft was passed through the hole of the distal clavicle and looped under the coracoid process. After leading portion of ten­don graft was looped over the clavicle, sutures were made between each end of the tendon graft with nonabsorbable suture materials.

  • Background: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. Methods: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. Results: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder ($8.2{\pm}7.9mm$ versus $7.3{\pm}3.4mm$, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal. Conclusions: In cases of an unstable distal clavicle fracture with coracoclavicular ligament disruption, satisfactory clinical results were obtained by locking plate fixation and coracoclavicular ligament suture augmentation concurrently.

  • Distal clavicle tunnel widening was observed in coracoclavicular ligament reconstruction with semitendinous tendon autografts in a patient with acromioclavicular joint injury. Acromioclavicular joint separation, in a 44 years-old man was treated by coracoclavicular ligament reconstruction. We have performed x-ray evaluation on 2years 10months after surgery. The immediate postoperative tunnel size was measured 4.5mm in diameter. At postoperative 2years 10month the tunnel diameter was from 9.3 to 11.4mm. But the weightbearing clavicle view showed no significant acromioclavicular joint separation. Moreover the patient complained only minor intermittent shoulder discomfort.

  • Weaver-Dunn's operation for acromioclavicular injury yields satisfactory results in most cases. Although clavicular prominence can recur, it is not frequently symtomatic, but it can cause serious impairment of shoulder function in young and active patients. The authors performed reconstruction of coracoclavicular ligament with an autogenous hamstring tendon graft in a 31 years old electrician with recurrence of clavicular prominence accompanied by pain and limitation of overhead activity. The hamstring tendon and two coracoclavicular sutures looped under the coracoid process were passed through holes in the clavicle and around the clavicle in overreduced position. Even though clavicular prominence recurred somewhat, the modified UCLA score by Rockwood improved to 17 from 11/20 at 2 years after operation and the patient had no restriction in working as an electrician. Symptomatic patient with recurrent clavicular prominence after Weaver-Dunn's operation can benefit from reconstruction of coracoclavicular ligament with a hamstring tendon.

  • Background: Modified Phemister operation has been widely used for the treatment of acute acromioclavicular (AC) joint dislocation. Additionally, the use of suture anchor for coracoclavicular (CC) fixation has been reported to provide CC stability. This study was conducted to evaluate the clinical and radiological results of a modified Phemister operation with CC ligament augmentation using suture anchor for acute AC joint dislocation. Methods: Seventy-four patients underwent the modified Phemister operation with CC ligament augmentation using suture anchor for acute AC joint dislocation and were followed-up for an average of 12.3 months. The visual analogue scale (VAS), range of motion, Constant score, and Korean shoulder scoring system (KSS) were used for clinical assessment. Acromioclavicular interval (ACI), coracoclavicular distance (CCD), and acromioclavicular distance (ACD) were obtained to evaluate the radiological assessments. Results: At the last follow-up, the mean VAS Score was 1.7 points, the mean joint range of the forward flexion was $164.6^{\circ}$, external rotation at the side was $61.2^{\circ}$ and internal rotation to the posterior was a level of T12. The mean Constant score and the mean KSS was 82.7 points and 84.2 points, respectively. At the mean ACI, CCD, and ACD, significant differences were found preoperatively and at the last follow-up. When the ACI, CCD, and ACD were compared with the contralateral unaffected shoulder at the last follow-up, the affected shoulders had significantly higher values. Conclusions: The modified Phemister operation with CC ligament augmentation using suture anchor is clinically and radiologically effective at acute AC joint dislocation.

  • Purpose: We evaluated clinical and radiological results for open reduction and internal fixation of acromioclavicular dislocation without coracoclavicular ligament repair after removal of implants. Materials and methods: Clinical and radiological results were obtained for 53 patients who underwent open reduction and internal fixation of an acromioclavicular joint dislocation between 1998 and 2007. A total of 21 patients were treated with a modified-Phemister method and 32 patients were treated with a Hook plate method. All subjects were surveyed after removal of their implants. The Constant scoring system was administered postoperatively to evaluate clinical results. Radiologic outcomes were evaluated by both coracoclavicular intervals on plain films. Results: Constant scores were $87.59{\pm}7.8$ in the Phemister group and $89.35{\pm}5.3$ in the Hook plate group. For both groups, the mean coracoclavicular interval at preoperative radiography was 15.9 mm at the injured site and 8.0 mm at the opposite site. After metal removal, the mean difference between coracoclavicular distances between normal and injured sites were 1.0 mm for the Hook plate group and 1.2 mm for the modified Phemister method group (p>0.05). Conclusion: Open reduction and internal fixation of an acromioclavicular joint without coracoclavicular ligament repair shows good long-term clinical and radiological results.

  • Purpose: The purpose of this study is to analyze the results of acute acromioclavicular joint dislocation treatment with coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ (Arthrex). Materials and Methods: From October 2009 to March 2011, 30 patients with acute acromioclavicular joint dislocation underwent coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ and were followed up for at least 12 months after surgery. The radiologic results were qualified according to serial plain radiographs, and the clinical results according to University of California - Los Angeles (UCLA) Shoulder Scale, Constant score, and VAS pain score. Results: Using the UCLA scoring system, excellent results were observed in 22 cases (73%), good results in five cases (17%), fair results in two cases (7%), and a poor result in one case (3%). The average Constant score was $92.5{\pm}7.5$. According to radiologic results, anatomical reduction was achieved in 26 cases, and two cases showed a moderate loss of reduction, and two cases showed complete re-dislocation. Clinical results for patients with re-dislocation were unsatisfactory and reoperation was required. Conclusion: Coracoclavicular ligament augmentation using Tight-Rope$^{(R)}$ is a good option providing reliable functional results in patients with acute acromioclavicular joint dislocation.

  • Background: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. Methods: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6- mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. Results: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. Conclusions: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

  • Purpose: There are so many different methods with the their own advantages and disadvantages for acute AC dislocation and distal unstable clavicle fracture. We evaluated the usefulness of temporary Bosworth's coracoclavicular fixations using the cannulated screw and reviewed our clinical results. Materials and Methods: We evaluated 34 cases of temporary coracoclavicular fixations with cannulated screw and washer for acute AC dislocation(25cases in the Type V, Ⅲ) and distal unstable clavicle fracture(9cases in the Type ⅡB, Ⅱ+Ⅲ). All cases were fixed by the same techniques, guided cannulated screw under C-arm after the repair of the CC ligament within 1 week. Bases on the regular check, screws were removed at the 6-12 weeks under local anesthesia. The final clinical and radiological results(average 14 months follow-up) were rated with the UCLA scale. Results : All shoulders were gained nearly full ROM passively at the 3-4 weeks. The overall satisfactory resuIts(excellent or good) were achieved 88%(22/25) in the acute AC dislocation and all in the distal unstable clavicle fracture. There were no definite complications except three initial fixations loosening. Conclusion: Temporary Bosworth's coracoclavicular fixation using the cannulated screw with guided pin was simple precedure and provided enough initial stability for acute AC dislocation and distal unstable clavicle fracture.
