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.

This paper is about a projection method to check existence of radius groove penetration of screw after distal radius fracture operation using the T-type plate. Angle of Radius groove was analyzed by fifty one CT images that contains patients' wrist and twenty cases of radius specimens. After making radius phantom by plaster, we set the screw so that it penetrated 2.4 mm depth of radius groove. Then, we projected the phantom by X-ray in change of the elevation and supination angle of distal radius by 5 degree interval on 0~30 degree. The average value of groove angle in the wrist CT images was 14.4 degree and the radius specimens was 16.3 degree. Screws penetrating radius groove of the phantom have different lengths according to elevation angle and supination angle. Consequently, in order to confirm existence and nonexistence of radius groove penetration of the screw in tangential projection after distal radius fracture operation using the T-type plate, we recommend 5 degree of elevation angle and 20 degree of supination angle.

Purpose: To evaluate and report the clinical and radiological outcomes of open reduction and internal fixation with a mini-T plate for unstable distal clavicle fractures. Materials and Methods: From December 2004 to July 2007, fifteen patients who had a fracture of the distal clavicle (Neer type II fracture) were treated with an open reduction and internal fixation using a mini-T plate. They were followed up for a minimum of one year and the clinical and radiological results were analyzed. Results: The average time to fracture union was 3.1(3~4) months. There were no complications, such as deep infection or fixation loss. The mean ASES score was 97 points (85~100points) at the last follow up period, and 14 patients had a full range of motion of the shoulder. Conclusion: Open reduction and internal fixation with a mini-T plate for unstable distal clavicle fracture is a good surgical method with good clinical and radiological results.

Purpose: This study is to analyze the result and complications of internal fixation with T-plate for two-part fracture of the neck of the humerus. Materials and Methods: The clinical results of fourteen patients who had been performed with this method mentioned above were reviewed. Their average age was 49.6. Postoperative mean follow up period was 24.1 months. Radiological evaluation was done by Kronberg's and shoulder function by Neer's. Results: By Kronberg evaluation, nine cases were good, two cases acceptable and three cases poor. By Neer's, mean score of shoulder function was 77.6 and 4 cases were excellent, one satisfactory, five unsatisfactory and four failure. The complications were the sfiff shoulder, loss of reduction and avascular necrosis of humeral head. Conclusion: In this study, there were differences according to the age. And we obtained an unsatisfactory result in patients over 50 years old. We consider that in patients over 50 years old, the differences were due to the muscle weakness through wide surgical approaches, postoperative implant loosening or the stiffness caused by poor rehabilitation.
