Abstract: PURPOSE
To evaluate the functional results after internal fixation with two low profile plates in fractures of the distal tibia.
MATERIALS AND METHODS
From March 1998 to October 2002, twelve patients with fractures of the distal tibia were treated with internal fixation using two low profile plates and followed for at least one year. Fractures according to AO/OTA classification were one Type A1, four Type A2, two Type C1, two Type C2 and three Type C3. We analyzed the functional results by the Olerud and Molander ankle scoring system and the postoperative complications.
RESULTS
The average functional score was 81.2 points and the results were three excellent, six good, one fair and two poor. Bony union was achieved in all cases. There was 1 case of superficial wound infection as a complication.
CONCLUSION
Internal fixation with two low profile plates in fractures of the distal tibia may minimize the incidence of soft tissue complications and provide good bony union and functional results. Therefore, we consider internal fixation with two low profile plates as a good alternative treatment of the distal tibial fracture.

Clinical Distribution of Bilateral Non-contemporary Hip Fractures in Elderly Patients: Hyung Ku Yoon, Duck Yun Cho, Dong Eun Shin, Sang Jun Song, Jong Hyun Kim, Byung Ho Yoon; J Korean Fract Soc 2005;18(4):375-378. Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.375

PURPOSE
To evaluate the clinical distribution of bilateral non-contemporary hip fractures regarding to fractures type, risk factors and fractures interval in elderly patients.
MATERIALS AND METHODS
24 bilateral non-contemporary cases among 621 hip fractures from Sep. 1997 to Dec. 2004 were evaluated regarding to gender, age, incidence, Singh index, causes, interval, fracture pattern, operative methods and underlying diseases between the two fractures retrospectively.
RESULTS
The distribution is as follows: males to females (5:19), incidence (3.86%), mean age (76.9 years and 78.9 years), average Singh index 2.5 degree (2~4) and 2.1 degree (1~3) respectively. 21 cases (87.5%) in both fractures suffered from minor slips and 19 cases (79.1%) occured within 3 years of the first fracture and 17 (68.1%) cases were same type fractures. Bipolar hemiarthroplasty was performed in 12 cases. All but one patient had underlying cardiovascular diseases and CVA sequales.
CONCLUSION
To prevent the bilateral non-contemporary hip fractures, surgeons must bear in mind that osteoporosis treatment, control of underlying cardiovascular diseases and CVA sequales, and the effective rehabilitation is very important.

Abstract PDF

PURPOSE
To evaluate the clinical and radiographic results of interlocking intramedullary nailing for the distal metaphyseal fractures of the tibia and to identify the usefulness of the interlocking intramedullary nailing.
MATERIALS AND METHODS
Thirty four patients who underwent interlocking intramedullary nailing for distal metaphyseal fractures of the tibia were reviewed with a follow-up period of more than 2 years. Clinical result was assessed using the Olerud score and this score was marked as percentage of prefracture state. Radiographic results were assessed with varus-valgus angle, anterior-posterior angle, and bone union time. We checked the cases of complication and need for additional surgery after interlocking intramedullary nailing.
RESULTS
Clinically, Olerud score averaged 92.1% (76~100%). Radiographically, average varus-valgus angle was 1.6+/-2.9 degrees and average antero-posterior angle was 0.8+/-3.3 degrees. Bone union time averaged 18.7 weeks. As complications, there were one deep infection and two breakages of distal interlocking screw. In additional surgery, there were 1 debridement and soft tissue flap, and one dynamization of nail at postoperative 12 weeks.
CONCLUSION
Interlocking intramedullary nailing is one of safe and reliable method for distal metaphyseal fractures of the tibia, considering less soft tissue injury, possibility of early range of motion exercise, high bone union rate, and low complications rate.

Abstract PDF: PURPOSE
To evaluate the functional changes, postop delirium and complications after cemented bipolar hemiarthroplasty for the femur neck fractures in patients aged around ninety.
MATERIALS AND METHODS
Between May 1995 and April 2002, of the twenty seven patients, 17 who follow-up for at least one year were included in this study. Walking ability, activity of daily living, mental status, chronic illness, postoperative delirium and complications were evaluated retrospectively using Yoon's walking class, ADL scale, MMSE-K score, ASA classification, DSM IV respectively.
RESULTS
The walking ability was decreased to 2.4 from 3.3 tendency of reliance in ADL scale was increased to 8.3 from 4.5, MMSE-K score was decreased to 15.9 from 21.7. There was no significant change in status of chronic illness. Postoperative delirium occurred in eight (47%) cases and all of them recovered completely. complications included bladder problem in eleven (66%) cases, temporary respiratory distress in two (12%) cases, hip dislocation in two (12%) cases, infection in one (6%) case. Overall thirteen (78%) cases were able to walk with supports.
CONCLUSION
This study indicates that physicians treation femur neck fractures in patients aged around ninety must anticipate worsening of the functional changes more especially in regard to walking level, activity of daily living and mental status, little changes of chronic disease status, complete recovery of postop delirium and high complication rate

Reduction of Pediatric Forearm Diaphyseal Fractures by Pin Leverage Technique: Soo Hong Han, Duck Yun Cho, Hyung Ku Yoon, Byung Soon Kim, Sung Hoon Kang, Tae Hyung Kim; J Korean Fract Soc 2004;17(1):59-63. Published online January 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.1.59

Abstract PDF

PURPOSE
Although the majority of children's forearm diaphyseal fractures may be treated conservatively with closed reduction and cast immobilization, unstable or irreducible fractures are usually treated by surgical management. Authors performed percutaneous pin leverage reduction technique for irreducible displaced diaphyseal fractures. The aim of this study is to determine the efficacy of pin leverage technique in pediatric forearm diaphyseal fractures MATERIALS AND METHODS: In this retrospective study, we reviewed 22 cases of forearm diaphyseal fractures reduced by percutaneous pin leverage technique between 1997 and 2002. We analyzed radiographs, operation time, hospital stay and immobilization period, range of motion, postoperative complications and functional results by Thomas.
RESULTS
Average length of follow up was 28 months with mean age of 10.5 years. All fractures in this series healed less than 2 degrees of diaphyseal angulation. Average operation time including anesthesia was 42 minutes and hospital stay was 4.6 days. Time to union was 49.6 days in average and range of motion and functional results were satisfactory in all cases except one case of congenital radioulnar synostosis. There was one case of superficial pin track infection as complication.
CONCLUSION
In operative treatment of children's diaphyseal fractures of forearm bones, percutaneous pin leverage reduction technique is a good alternative method prior to open reduction in case of difficult closed reduction.

The Correlation between Surgical Timing and Perioperative Complications in the Treatment of Displaced Supracondylar Humeral Fractures of Children: Soo Hong Han, Duck Yun Cho, Hyung Ku Yoon, Byung Soon Kim, Jae Hwa Kim, Hyung Kun Park, Se Hyen Kim; J Korean Soc Fract 2003;16(2):278-283. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.278

Abstract PDF: PURPOSE
Even though emergent percutaneous pinning after closed reduction is the popularized treatment of the displaced type II and type III pediatric supracondylar fractures of the humerus, the timing of pinning still presents controversy. The purpose of this study is to suggest an appropriate surgical time without significant perioperative complications.
MATERIALS AND METHODS
From April 1995 to January 2002, 179 consecutive patients who had undergone surgical treatment were selected. They were divided to 5 groups [A group: 8 hours or less following injury (24 cases), B group: from 9 to 16 hours (63 cases), C group: from17 hours to 24 hours (63 cases), D group: from 25 hours to 48 hours (18 cases), and E group: from 49 hours to 72 hours (11 cases)] and reviewed retrospectively to analyze perioperative complications and operation time.
RESULTS
There was no significant difference between each group with respect to surgical wound infection, iatrogenic ulnar nerve injury, VIC, operation time and the necessity of reoperation (p>0.05).
CONCLUSION
Within the parameters outlined in our study, we could not find the any meaningful correlation between surgical timing and occurrence of perioperative complications and also, we think that the timing of percutaneous pinning can be delayed to the time when a surgeon considers it appropriate.

Common Modes of Fixation Failure with a Sliding Hip Screw encountered Unstable Intertrochanteric Fracture: Byung Soon Kim, Duck Yun Cho, Hyung Ku Yoon, Dong Eun Sin, Soo Hong Han, Jae Hwa Kim, Dong Jun Kim; J Korean Soc Fract 2003;16(1):15-21. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.15

Abstract PDF

The purpose of this study was to evaluate the common modes of fixation failure in unstable intertrochanteric fractures , related risk factors and the prevention of fixation failure. Between 1995 and 2001, 44 patients who had sustained an unstable intertrochanteric fractures were assigned to be treated with a sliding hip screw. Men in 14 cases ( 32% ), women in 30 cases ( 68% ) , the average age at the operation was 65(22-90) years and the average duration of follow up was 12(8-22) months. We classified the fracture patterns with Evans system and used Singh 's index for osteoporosis. And we examined the common modes of fixation failure with postoperative X-ray. The fixation failure in unstable intertrochanteric fracture was 8 cases (18.2 % ); varus collapse of the proximal fragment with cutout of the lag screw was 3 cases (6.8%), varus collapse of the proximal fragment with excessive sliding of the lag screw was 4 cases (9.1%) and loss of fixation of the plate-holding screws was 1 case (2.3%). The authors think that inadequate anatomical reduction of comminuted posteromedial fragment and severity of osteoporosis are main causes of fixation failure. During operation for unstable intertrochanteric fractures, the most important point is accurate reduction of posteromedial fragment and the intramedullary hip screw like proximal femoral nail ( PFN ) may be considered to avoid fracture of lateral cortex that enter the lag screw, causing fixation failure.

Abstract PDF: PURPOSE
We analyzed the anatomical results of operative treatment in acetabular fractures according to fracture pattern and surgeon's experience. MATERIAL AND METHODS: From December, 1993 to December, 1999, 100 cases of acetabular fractures operated by single surgeon were analyzed. Fracture configuration was classified by Letournel's method. The anatomical results were classified by Matt' s criteria and Claude Martimeau score.
RESULTS
There were 36 elementary fractures(anterior column type: 4 cases, posterior wall type: 29 cases, transverse type: 3 cases) and 64 complex fractures(posterior wall and posterior column type: 4 cases, anterior and posterior hemitransverse type: 8 cases, transverse and posterior wall type: 16 cases, T type: 6 cases, both column type: 30 cases). According to Matta's criteria, all elementary fractures were seen anatomic or satisfactory results however, eleven cases of combined fracture were seen unsatisfactory results. Mean Claude Martimbeau's score was 6.1 point. Elementary fracture was 7.5 point and combined fracture was 5.4 point. Both column fracture was 4.4 point and it was the lowest point among the fractures. In both column fracture, the improvement of surgeon's skill made more good anatomical results. There were four cases of infection and 2 cases of nerve injury.
CONCLUSION
In operative treatment of acetabular fractures, complexity of fracture demands more appropriate surgical approach and skillful surgeon,

Clinical Study of Prognostic Factors in Patellar Fractures: Duck Yun Cho, Hee Chun Kim, Chung Hwan Kim; J Korean Soc Fract 1996;9(4):977-983. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.977

Abstract PDF: Most authors report 70% to 80% good to excellent results following open reduction and internal fixation of fractures of the patella. As with most intraarticular fractures, the prognosis for healing and restoration of function in fractures of the patella is dependent on the amount of articular cartilage damage and exact reduction of fracture. In order to document clinical results and describe any prognostic factors, we evaluated the results of 69 patellar fractures treated in 66 patients who had been treated with open reduction and internal fixation at the Department of Orthopaedic Surgery, Nationanl Medical Center, from January 1990 to December 1994. The average age at the time of surgery was 41.2 years(16 years-75 years) and the average follow-up time was 38.7 months(14 months-74 months). The results were as fellows: 1. The mechanism of injury(traffic accident), concomittant inury of ipsilateral lower extremity, fracture morphology, immgbilization period less than two weeks and accuracy of reduction were significant prognostic factors. 2. Age and method of fixation were not significant prognostic factors. 3. The brisement of knee under general anesthesia was helpful, that had been performed following bony union.

Treatment of Infected Nonunion of the Femur Using the Ilizarov Apparatus: Duck Yun Cho, Eun Sung Koh, Suk Cho Kong; J Korean Soc Fract 1996;9(4):899-906. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.899

Abstract PDF: Infected nonunion is serious complication in the long bone fractures and it is sometimes resulted in significant disability. From December 1990 to February 1994, we reviewed 11 cases who were treated for infected nonunion of the femur by using the Ilizarov apparatus at National Hedical Center, Active infection was controlled by radical resection of the infected necrotic bone and soft tissue and continuos irrigarion with antibiotics mixed saline for 3 weeks. After sequrstrectomy, bone deject was ranged from 2.5cm to 12.5cm(average, 7.2cm) in 11 cases. Preoperative leg length discrepancy(LLD) was ranged from 2.0cm to 8.Ocm(average, 3.9cm) in 7 of 11 cases. Bone defects were gradually treated by internal bone transport technique and solid bone union was achived by internal fixation and bone graft. The average of transporation was 8.9cm(range, 2.5-15.5cm). The average of healing index was 1.6menths/cm(range, 1.0-3.6months/cm). The percentage of increment was ranged from 5% to 32%(average, 19.6%). According to Paleys classification, bony results was poor in 11 cases and functional results was good in four, fair in three, poor in four. We concluded that the application of Illizarov technique to infected nonunion of the femur with large bone defect was useful method but internal fixation and bone graft was necessary for nonunion of doicking site.

Patellar Fracture: Duck Yun Cho; J Korean Soc Fract 1996;9(4):835-840. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.835

Abstract PDF: Patellar fractures constitute approximately 1 percent of skeletal injuries in the literature and 3.4 percent in the authors institution. The goals of treatment are restoration of the entensor mechanism and perfect restoration of the articulating surface. In contrast to most other intraarticular fractures, the selection of treatment must take into consitleration tensile suess of the bone, as were as compressive stress. The basic schema for treatment of patellar fracture is as follows: 1. To determine therapy, patellar fractures must be classified in 3 models;The mechanism of injury. amount of displacement, and configuration of fracture. 2. Nonoperative treatment is indicated if the extensor retinaculum is intact and if displacement of fragment is minimal. 3. The success of operative treatment depends on the exact reduction of fracture, secure fixation, and the amount of articular cartilage damage. 4. Recent biomechanical studies on the efficiency of various forms of fixation for patellar fractures showed that fixation with modified tension band wiring with or without circumferentiat wiring was superior to tension band wiring or circumferential wiring. 5. Partial patellectomy should be selected in preference to total patellectomy if at all possible because partial patellectomy offers better function.

Abstract PDF: Infected nonunion of the tibia was most serious complication in the tibial fracture and it have had many obstacles in treatment. Various treatment methods for infected nonunion have been performed to achieve bony union and restore bony defects after sequestrectomy. From Febrary 1991 to June 1993, the authors reviewed 12 cases who were treated for infected nonunion of the tibia with bone defect by the Ilizarov technique at National Medical Center to achieve union. to correct deformity, to eradicate infection, to reestablish limb length, and to eliminate bone defect. These infected nonunions were treated by on bloc resection of the diaphyseal shaft and internal bone transport. Final equalization of leg length inequality was achieved by external lengthening technique. Preoperative shortening was present in 1 of 12 cases and ranged from 1cm to 4cm (average,2.0cm). Bone defects size was ranged from 2cm to 7cm(average 4.5cm). Tibial corticotomies were performed at the proximal level in 8 cases and at the distal level in 4 cases. Regnerated new bone was ranged from fun to 9cm(average, 5.8cm). The average healing index was 2.54 months/cm. At an average 18 months follow up, according to Paley and Catagnis classification, bony results were excellent in five, good in six, poor in one and functional result were excellent in one, good in five, fair in five. poor in one. We concluded that the application of Ilizarov technique to resistant infected nonunion of the tibia with bone defect was very encouraging and useful method.

Abstract PDF: Fracture of scaphoid are second most common fractures of wrist, and about 1/6 of these fractures proceed to nonunion. The most widely used surgical procedure of scaphoid nonunion has been Matti-Russe procedures,and Hebert screw is a recently introduced fixation device as a means of rigid internal fixation promoting union and decreasing immobilization time. Authors have managed 15 cases of scaphoid nonunion with Mtti-Russe bone grafting technique and herbert screw, and accomplished satisfactory results: The union rate Was 96.6%, the average time to union was 17.1 weeks, and according to Maudsleys assessment criteria, we obtained 7 cases of excellnt, 6 good, and 2 fair results. Despite of its technical demand and lack of the number and study material, Matti-Russe bone grafting technique with Herbert screw fixation seems efficient and reliable method of treatment.

Clinical analysis of fractures around the elbow joint in adults: Duck Yun Cho, Joong Myung Lee, Hee Chun Kim, Hyeong Jin Kim; J Korean Soc Fract 1995;8(2):430-438. Published online April 30, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.2.430

Abstract PDF

The fractures around the elbow joint in adults are relatively rare in comparision with that in children, but the late complications are more common in adult. So, it is important to select the appropriate early management to prevent the late sequelae. Complications are joint contracture, persistant pain, nonunion, deformity, neurologic symptom, infection. etc. Among them limited range of joint motion is the main problem. We, authors have clinically and radiologically analyBed 48 cases of fracture around the elbow joint in adults over the age of 20 years, treated at the Department of Orthopaedic Surgery in National Medical Center from January 1984 through December 1993. The results are as follows: 1. The age incidence was higher in active young persons and the male to female ratio was 3:2. 2. The most common cause of the injury was slip-down(46%), followed by traffic accident(29fo), falling, and athletic injury. 3. In total 48 cases, olecranon fractures were 29 cases, fractures of distal humerus 13 cases, radial head fractures 5 cases, and multiple fractures (including olecranon, radial head and intercondyle) was 1 case, Among them. open fractures were 5 cases. 4. Closed reduction with cast immobilization or K-wire fixation was performed in 8 cases, and open reduction and internal fixation was performed in 37 cases. In 3 cases. radial head resection was done. 5. The most common complication was limited range of the joint motion (9cases), followed by nerve injury(3 cases), infection(3 cases) and nonunion(1 cases). 6. Development of limited range of joint motion was increased in case of old age over 60 years(33%), open fracture(60%), longer immobilization period over 6 weeks(27%). Though fracture around the elbow joint in adult is reletively rare. it frequently results in limitation of the joint motion and has poor prognosis For prevention of limitation of joint motion, rigid fixation and shortening of immobilization period and early rehabilitation are necessary.

Operative Treatment of Proximal Humeral Fracture using Inlay Graft of Fibular Allograft Combined with Plating: Duck Yun Cho, Eun Sung Koh, Myong Hyoung Lee; J Korean Soc Fract 1995;8(1):84-92. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.84

Abstract PDF

Fracture of the proximal humerus occurs more frequently in older individuals who may have advancing osteoporosis, causing the bone to weaken, even with minimal force. And, most proximal humeral fractures respond satisfactory to conservative treatment. But, operative treatment is reconmended in the case that poor results are anticipated by the severe displacement and comminution. In older patient with proximal humerus fracture, there was some problem such as osteoporosis, absorption of cancellous bone, cystic formation, and weakness of the mechanical support, and it has difficulties in rigid fixation and early ROM. Four cases of displaced fracture of the proximal humerus in older patients over 50-year-old Treated by using plate & inlay fibular allograft from Apr. 1991 to Dec. 1993 were analized clinically and radiologically. The following results were obtained. 1. The results of these patients were rated by the Neers functional criteria. Of four cases, three cases had excellent results, one case had satisfactory. 2. There was no allograft related complications, such as infection & graft rejection. So, in treatment of proximal humerus fracture at old individuals, open reduction and internal fixation with plating and inlay graft using fibular allograft was very useful method, and it resulted in rigid fixation, early ROM. and good functional result.

Abstract PDF: Infected large defect of the long bone have had many obstacles in treatment. It is usually very difficult to obtain union and to correct coexisting infection, deformity, & leg length discrepancy, Allograft transplantation have been traditionally used to treat infected large defect of the long bone. And Ilizarov technique has recently gained popularity as a multifactorial approach to the management of infected large defect of the long bone. We performed allograft transplantation in 5 cases and Ilizarov technique in 6 cases with infected large defect of the long bone at National Medical Center from 1987 through 1991. The results were as follows; 1. In the cases of allograft transplantaton, the average size of the bone defect was 9.6cm (range from 6cm to 3cm) and the average length of leg length discrepancy was 2.4cm (range from 0cm to 4cm). 2. In the six cases of Ilizarov technique, the average size of the bone defect was 2.5cm(range from 0.5cm to 4.5cm) and the average length of leg length discrepancy was 3.7cm(range from 0cm to 7cm). 3. In the cases of allograft transplantation, the bone union was achieved in two cases. Two cases have been followed up for 19 and 26 months each and they showed complete bone union in the proximal side of host-graft junction, but not complete union in the distal side. In one case, developed the osteolysis of the grafted bone due to the infection. After operation, the average length of leg length discrepancy was 1.4cm(range from 0 cm to 2cm). 4. In the cases of Ilizarov technique, bone union was achieved in three cases. One case have been followed up for 15 menths and showed incomplete bone union. In two cases, additional operation was performed due to the nonunion and the fracture between the junction of the proximal bone fragment and the transportated bone fragment in each. So we report our results of diferent two methods of treatment even if limited cases and experiences.

A Clinical Study of tibial Pilon Fractures: Key Yong Kim, Duck Yun Cho, Jai Gon Seo, Sung Bum Yang, Kyu Jung Cho; J Korean Soc Fract 1989;2(2):211-218. Published online November 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.2.211

Abstract PDF: The tibial pilon fracture is one of the most difficult fracuture to treat because of severe metaphyseal bone defect, comminution of the articular surface, disruption of ankle mortise and accompanying soft tissues injury resulting from axial compression and rotational forces. The recent concept of management of tibial pilon fracture is to open and provide anatomical reduction with stable internal fixation, early joint motion and considerably delayed weight bearing. We reviewed 16 cases of tibial pilon fracture experienced from June 1985 to December 1 988 and the result were as follows; Tibial pilon fracture comprises 8.7% of all ankle fractures(183 cases) during the period and prevalent in male. According to the classification by Ruedi and Allgoewer, 2 cases of typeI, 9 cases of type II and 5 cases of type III. 3 cses treated conservatively and 13 cases operatively. Better results were obtaiined in latter group, and in typeI and type II than III. The important factors influencing the clinical result were the type of fracture and accuracy of reduction including maintainace of fibular length.
