Purpose: To evaluate the result and complication of treatment using Locking Compression Plate (LCP) for fracture of proximal humerus. Materials and Methods: Between 2004 and 2006, 21 patients with two-part and three-part fractures of the proximal humerus were treated by LCP fixation. Their average age was 54.9 years. Postoperative mean follow-up period was 22.9 months. The reduction was qualified and complication were assessed with final radiographs. The functional outcome was evaluated by Neer's rating system. Results: By Neer's functional evaluation, mean score of shoulder function was 86.3 and 18 case (86%) had excellent or satisfactory results. There was one case of nonunion but no infection or avascular necrosis of the humeral head. No correlation was found between the final result and the type of fracture, age, gender or quality of reduction. Conclusion: We obtained satisfactory result of LCP fixation for fracture of proximal humerus in this study. LCP fixation for proximal humerus fracture is a reliable method to obtain satisfactory reduction, rigid fixation and early exercise.

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.

Purpose: The purpose of this study is to evaluate the clinical and radiological outcomes of treatment of humerus shaft simple fracture by minimally invasive percutaneous osteosynthesis (MIPO) technique using locking compression plate (LCP). Materials and Methods: Six patients who were operated for humerus shaft simple fracture from August 2010 to May 2011 were enrolled for this study. We checked the cause of injury and the accompanying injuries and evaluated the operation time, the clinical and radiological period of union, postoperative range of motion of the shoulder and elbow joint, pain, activities in daily living, radiologic alignment, and other complications. Results: The clinical period of bone union was 7.2 weeks on average, and the radiologic period of bone union was 8 weeks on average. Follow-up period was more than 12 months in all cases. The angulation through postoperative alignment was 2.8 degrees in AP view and 2 degrees in lateral view. The postoperative range of motion was 167 degrees in forward flexion, 50 degrees in external rotation, and thoracic vertebra 12 level in internal rotation. The average value of visual analogue scale (VAS) was 1.2 and that of KSS was 91.3. The American Shoulder and Elbow Surgeons' score (ASES) was 26.5 and the UCLA score was 31.5. Conclusion: MIPO technique for the humerus shaft simple fracture showed good functional and radiological outcomes and may be considered as one of the treatment options for humerus shaft simple fracture.

Purpose: A comparison of the radiographic and the clinical outcomes between two different surgical approaches-Deltoid splitting and Delto-pectoral interval-on the proximal humerus fractures treated by locking compressive plate (LCP), is done. Materials and Methods: Medical records and pre- and postoperative radiographs were reviewed retrospectively for 75 adult patients who underwent surgical fixations with locking compressive plates from May 2005 to December 2011. Patients were divided into two groups according to the surgical methods. Differences in the neck-shaft angle between immediate postoperative period and final follow-up were compared between the two groups. Differences in constant score and Korean shoulder score (KSS) between affected arms and contralateral arms at final follow-up were also compared. Results: The differences in the neck-shaft angle between immediate postoperative period and at final follow-up was 12.04 degrees on average in Deltoid splitting approach and 10.20 degrees in Delto-pectoral interval approach, which was not statistically significant. Differences in constant score/KSS between the affected arm and the contralateral arm were 13.78/22.74 points in deltoid-splitting approach on average and 19.41/31.13 points in Delto-pectoral interval approach, showing that deltoid-splitting approach is significantly superior. Conclusion: Deltoid-splitting approach showed better functional outcomes in the fracture reduction and internal fixation using LCP for the treatment of unstable proximal humerus fractures.

A painful pseudoarthrosis will develop due to a delay in diagnosis and treatment, and surgical care is required. Treatment of pseudoarthrosis is really difficult because the acromion is a thin flat bone that is difficult to be fixed firmly. A 52-year-old woman with multiple trauma had an acromial fracture that was not detected until it had caused pain after ambulation. Open reduction and internal fixation with a variable angle locking compression plate for distal radius and autogenous iliac bone graft were performed. At nine months after the operation, there was partial tear in the supraspinatus tendon, and arthroscopic repair of the supraspinatus tendon was performed. At nine months after the operation, radiographs showed a complete union. At three months after tendon repair, the patient had excellent function of the shoulder. We have reported a case of a successful treatment of nonunion and pseudoarthrosis of acromial fracture that is difficult to be fixed.
