Double Parallel Plates Fixation for Distal Humerus Fractures: Young Hak Roh, Moon Sang Chung, Goo Hyun Baek, Young Ho Lee, Hyuk Jin Lee, Joon Oh Lee, Kyu Won Oh, Hyun Sik Gong; J Korean Fract Soc 2010;23(2):194-200. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.194

Abstract PDF: PURPOSE
The purpose of this study was to review the outcome of fixation of distal humerus fractures using recently-introduced double parallel plate system in sagittal plane.
MATERIALS AND METHODS
From May 2004 to June 2008, seventeen patients with distal humerus fractures underwent primary open reduction and internal fixation with double parallel plates. According to the AO classification, there were 2 A3, 2 C1, 7 C2, and 6 C3 type fractures. Outcome assessment was performed by using the Mayo Elbow Performance index (MEPI).
RESULTS
At a mean follow up of 18 (range, 12 to 32) months, 4 patients were rated as excellent, 8 as good, and 5 as fair in terms of MEPI. The average arc of elbow flexion after primary operation was 116 (range, 90~140) degrees with a mean flexion contracture of 13 (range, 0 to 30) degrees. One patient required reoperation due to fixation failure and six patients underwent capsulolysis and three patients underwent ulnar nerve neurolysis. The time to begin elbow motion exercise had negative correlation with total elbow range of motion and multiple trauma patients had significantly lower MEPI functional score compared to those without combined injury.
CONCLUSION
Double parallel plating allowed adequate fixation for distal humerus fractures regardless of patient age and fracture pattern. Partial ankylosis and unlar nerve compression symptoms were the main causes of reoperation.

Surgical Treatment of Femoral Nonunion: Hyun Sik Gong, Hee Joong Kim, Han Soo Kim, Goo Hyun Baek, Sang Hoon Lee, Sang Rim Kim, Moon Sang Chung, Young Min Kim; J Korean Soc Fract 1999;12(1):1-5. Published online January 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.1.1

Femur is one of the most frequent sites of nonunion and femoral nonunion imposes many complications secondary to repeated surgical procedures and immobilizations. Many kinds of treatment options have been used and studied for comparison, but still the classical principle is rigid fixation, bone grafting, and adequate postoperative immobilization. In this study, the results of surgical treatment for femoral nonunion were analyzed. From July 1995 to August 1997, a total of 14 cases of femoral nonunion were treated surgically at the department of Orthopedic Surgery of the Seoul National University Hospital. All cases were treated by autogenous bone graft and internal fixation. For internal fixation, plate and screws were used in 10 cases and intramedullary nail in 3 cases and compression hip screw in 1 case. Postoperatively, hip spica cast was applied in 8 cases, cast brace in 2 cases and long leg splint in 1 case. In the other 3 cases, no additional support was adopted. In all cases, clinical union was achieved at postoperative 5 months in average. There was no significant complication except one case of marked limited motion in knee followed by hip spica cast.

Bioresorbable Implant Fixation for the Treatment of Radial Head and Neck Fractures: Coo Hyun Baek, Young Jin Sohn, Choon ki Lee, Moon Sang Chung; J Korean Soc Fract 1998;11(1):70-77. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.70

Abstract PDF: Between March 1988 and March 1995, 10 patients with displaced Mason type II, type III, or type IV fracture of the radial head or neck were treated by open reduction and internal fixation using bioresorbable pins. The average age of the patients was 38 years (22 to 70), and average follow-up period eas 14 months (12 to 18). There were 4 type II, 4 type III, and 2 type IV fractures. According to the functional rating system of Broberg and Morrey, the clinical results were reviewed at an average follow-up of 14 months. The functional results were 4 excellent, 5 good, and 1 fair. Fixation of displaced radial head or neck fracture using bioresorbable pins, was considered as one of the good methods.

Treatment of Fractures of Lateral Condyle of Humerus with Compliations: Moon Sang Chung, Sung Churl Lee; J Korean Soc Fract 1995;8(3):659-666. Published online July 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.3.659

Abstract PDF

Fractures of the lateral condyle of the humerus are notorious for complications, most commonly nonunion with subsequent proximal migration of the ununited fragment, an increase in the carrying angle, and the tardy ulnar nerve palsy. In the past, the reconstructive surgery for complicated old fractures of the lateral condyle of the humerus had been hardly considered, but recently, attempts have been made to reconstruct the anatomy and function of the elbow joint. The authors have reviewed 21 cases of old fractures of the lateral condyle of the humerus, which had been treated at Seoul National University Hospital from April,1982 until March, 1990. For established nonunions of the lateral condyle fragment, better results were obtained from the procedure that includes osteosynthesis of the lateral condyle, attempting to restore the normal anatomy of the elbow joint. For tardy ulnar nerve palsies, better results were obtained from the procedure that includes medial epicondylectorny. Fractures of the lateral humeral condyle have many late problems in spite of treatment at the time of injury so early aggressive treatment is necessary. Even in cases with late problems, aggressive treatment should be done, too, as soon as possible.

Treatment of Nonunion Using Electrical Stimulation Only: Se Il Suk, Moon Sang Chung, Sang Hoon Lee, Phil Hyun Chung, Moon Sung Han, Yong Min Kim; J Korean Soc Fract 1989;2(2):274-280. Published online November 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.2.274

Abstract PDF: Negative electric charge is known to induce osteoblastic activity in bone. Therefore, electrical stimulation can be used clinically to promote more active new bone formation in the fracture site. Among many methods in the treatment of fracture nonunion, electrical stimulation can be emplyed as one of the useful methods, which is less of noninvasive and rather simple. We experienced 10 cases of fracture nonunion managed with EST without surgery in the Department of Orthtopedic Surgery of Seoul National University Hospital from September 1980 to March 1987. Of these, 6 cases were managed with semiinvasive direct current method and resulted in union of all cases. 4 cases were managed with nonivasive capacitively coupled electric field method and resulted in union iin 3 cases but in1 case, nonunion persisted till 22 months follow-up. In the 9 cases of satisfactory results, union time varied from 2 months to 9 months with mean of 4 months. No remarkable complication was found in these cases. In conclusion, electrial sitmulation therapy is thought to be one of the useful and hopeful methods in the treatment of fracture nonunion cases in which surgery is not absolutely indicated.

Clinical Study of the Trans-Scaphoid Perilunar Dislocation: Moon sang Chung, Choon Seong Lee, Se IL Suk; J Korean Soc Fract 1988;1(1):43-53. Published online November 30, 1988; DOI: https://doi.org/10.12671/jksf.1988.1.1.43

Abstract PDF

It is possible to diagnose trans-scaphoid perlunar dislocation(TSPD) with simple anteroposterior and lateral roetgenograms, But, there are many cases in which we make a wrong diagnosis as simple scaphoid fracture or perilunar dislocation. Most of the 7 cases among the 11 cases who visited Seoul Natioinal University Hospital from 1981 to 1987 were delayed 3 or more weeks because they were misdiagnosed as simple fracture, sprain or dislocation. It is important to identify the relationship of scaphoid with capitate or radius with simple lateral roetgerogran and we nust suspect accompanying perilunar dislocation if there is rotationary deformity in scaphoid fracture. We consider open reduction and internal fixation is better than closed reduction as treatment of TSPD because scaphoid fracture is easy to displace due to instability of fracture fragments in most cases. And we also suggest it is better to try open reductioin and internal fixation first than salvage operation as initral tratment of old fractures, if there is no osteoporosis and resorption of scaphoid fragment.
