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.

Purpose: The purpose of this study is to compare the clinical and radiological outcomes of two surgical treatments, transacromial pin fixation and hook plate fixation, for unstable distal clavicle fractures. Materials and Methods: Twenty four patients with Neer type II distal clavicle fractures who underwent surgery with transacromial pin fixation (Group I: 12 patients) and hook plate fixation (Group II: 12 patients) were included. Reduction and union were evaluated using plain radiographs. Functional evaluation was performed according to UCLA score and Constant-Murley score at last follow-up. Results: All 24 cases showed bone union. Complete union took an average of 10 weeks for group I and 11.7 weeks for group II. Average UCLA score was 33 (group I) and 32.8 (group II). Average Constant score was 88.5 (group I) and 88.8 (group II). No significant difference for each variable was observed between the two groups. Conclusion: For the surgical treatment of Neer type II distal clavicle fractures, transacromial pin fixation and hook plate fixation are both useful methods.

Purpose: To review the clinical and radiological results after an open reduction and internal fixation with a T-shaped LCP for unstable distal clavicle fractures. Materials and Methods: From February 2005 to June 2006, ten patients with distal clavicle Neer type II fractures were treated with an open reduction and internal fixation with a T-shaped LCP. Bony union was identified by plain radiography. The clinical results were analyzed according to the UCLA scoring system. Results: The mean time to fracture union was 9weeks and union was achieved in all cases. The mean UCLA score was 33.4 (30-35); excellent in 8 cases and good in 2 cases. In one case, loosening of one distal screw was occured and mild AC joint subluxation was observed in another case. Conclusion: 3.5 mm T-shaped LCP fixation is a useful technique for treating unstable distal clavicle fractures. This procedure provide stable fixation with no further AC joint injury.

We presented a case of posteriorly displaced fracture of the distal clavicle in Child. The closed reduction was failed due to posteriorly displaced proximal fragment and interpositon of trapezius muscle and periosteum. We found that periosteal sleeve and coracoclaviclar ligament and acromioclavicular ligament was intact. The open reduction should be considered for the treatment of the irreducible posteriorly displaced fracture of the distal clavicle in child.

Background: In aortic surgery, division and ligation of the left brachiocephalic vein(LBV) may improve exposure of the aortic arch but controversy continues about the safety of this division and whether a divided vein should be reanastomosed after arch replacement was completed. The safety of LBV division and the fate of the left subclavian venous drainage after LBV division were studied. Material and Method: From November 1998 to January 2001, planned division and ligation of the LBV on the mid-line after median sternotomy was peformed in 10 patients during the aortic surgery with the consideration of local anatomy and distal aortic anastomosis. Assessment for upper extremity edema and neurologic symptoms, measurement of venous pressure in the right atrium and left internal jugular vein, and digital subtraction venography(DSV) of the left arm were made postoperatively. Result: In 10 patients there was improvement in access to the aortic arch for procedures on the ascending aorta or aortic arch. The mean age of patients was 62 years(range 24 to 70). Follow-up ranged from 3 weeks to 13 months. One patient died because of mediastinitis from methicilline-resistant staphylococcus aureus strain. All patients had edema on the left upper extremity, but resolved by the postoperative day 4. No patient had any residual edema or difficulty in using the left upper extremity during the entire follow-up period. No patient had postoperative stroke. Pressure difference between the right atrium and left internal jugular vein was peaked on the immediate postoperative period(mean peak pressure difference = 25mmHg), but gradually decreased, then plated by the postoperative day 4. In all DSV studies left subclavian vein flowed across the midline through the inferior thyroid venous plexus. Conclusion: We conclude that division of LBV is safe and reanastomosis is not necessary if inferior thyroid vein, which is developed as a main bridge connecting the left subclavian vein with right venous system, is preserved.
