Published online January 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.1.21

Abstract PDF: PURPOSE
The aim of this study is to decide the optimal level of fusion with comparing the results between the short segment fusion and long segment fusion treated with pedicle screw instrumentation, including fractured vertebra in thoracolumbar junctional fractures.
MATERIALS AND METHODS
From February 2000 to November 2009, fifty three patients with junctional fracture of thoracolumbar spine were treated with pedicle screws and posterior fusion at our hospital. They were divided into two groups, the short segment group and long segment group. Preoperatively, immediate postoperative and last follow-up lateral radiological evaluation was done by measuring the correction and loss of segmental kyphosis, wedge angle, body compression rate and instrumented vertebra angle. In addition, operation time and amount of intraoperative bleeding were measured.
RESULTS
There were no significant differences of statistical analysis regarding the radiological variables between the two groups, especially the loss of corrected segmental kyphosis, wedge angle, body compression rate and instrumented vertebra angle (p>0.05). However, operative time in the short segment group (234 minutes) was shorter than the long segment group (284 minutes), and there was statistical significance (p=0.002).
CONCLUSION
We recommend the short segment transpediculr instrumentation one level above and one level below, including the fractured vertebra for thoracolumbar junctional fracture with 6 points or less of the load-sharing score.

Published online July 31, 2012; DOI: https://doi.org/10.12671/jkfs.2012.25.3.191

Abstract PDF: PURPOSE
To evaluate the clinical and radiologic results of the Kapandji procedure in AO classification type C distal radius fracture patients over 60 years old.
MATERIALS AND METHODS
Twenty-one type C distal radius fracture patients over the age of 60 years who were treated with the Kapandji procedure from June 2004 to June 2009 in our hospital and had a post-operative follow-up period of more than 1 year were enrolled. The volar tilt, radial inclination, and radial length were measured for the radiographic analysis using the modified Lidstrom scoring system about post-operative reduction loss in every follow-up radiogram. The clinical result was assessed with a visual analogue scale (VAS) and Korean Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) score at the last follow-up.
RESULTS
The mean radiologic loss of volar tilt was 1.1degrees and the mean loss of radial length was 2.6 mm and the mean radial inclination loss was 2.7degrees compared with the immediate post-operative period and last follow-up period. The average VAS and DASH scores were 1.4 and 15.9.
CONCLUSION
The radiologic results of closed reduction and percutaneous pinning using the Kapandji technique for distal radius AO type C fracture patients over 60 years of age was not satisfactory. Nevertheless, the clinical results were satisfactory.

Open Reduction and Internal Fixation with AO Calcaneal Plate for Displaced Intra-articular Calcaneal Fracture: Myung Jin Lee, Sung Keun Sohn, Kyu Yeol Lee, Sung Soo Kim, Min Soo Kang, Hyeon Jun Kim, Sang Kyu Sun; J Korean Fract Soc 2010;23(3):303-309. Published online July 31, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.3.303

PURPOSE
To evaluate the surgical outcomes of open reduction and internal fixation of AO calcaneal plate in displaced intra-articular fractures of the calcaneus.
MATERIALS AND METHODS
From January 2004 to July 2007, 25 patients with 27 displaced intra-articular calcaneal fractures were treated by open reduction and internal fixation using the AO calcaneal plate. Preoperative, postoperative evaluations and a follow-up after 1 year were done radiologically by the Bohler angle, Gissane angle, heel height and width among all patients. Their functional status was assessed by means of the Maryland foot score.
RESULTS
The mean Bohler angle, Gissane angle, heel height and width were restored comparing with preoperative data. However, in Sanders type IV, some losses of reduction occurred at 1 year follow-up (p<0.05). The mean Maryland foot scores were 85 points in type II, 82 points in type III and 63 points in type IV. Sanders types significantly affected the clinical results (p<0.05).
CONCLUSION
The AO calcaneal plate fixation using extensile L-shpaed lateral approach shows satisfactory radiologic and clinical results in the treatment of displaced intra-articular calcaneal fractures.

Abstract PDF

PURPOSE
To evaluate functions of the elbow joint according to surgical approach, time to exercise, and type of fracture after surgical treatment for the intra-articular comminuted fracture of the distal humerus.
MATERIALS AND METHODS
27 patients with the intra-articular comminuted fractures of the distal humerus underwent surgery from March, 2000 to January, 2007. We investigated the surgical approach, time for union, time to exercise and age. We also evaluated postoperative functions of the elbow joint according to the flexion contracture, the range of motion and the Mayo elbow performance score.
RESULTS
The average follow-up period was 37 months and the average time for union was 14 weeks. The average range of flexion was 115 degrees, the average flexion contracture was 10 degrees, and the Mayo elbow performance score with average value of 85 point showed good clinical results. There were no statistically significant differences in functions of the elbow joint according to the operative method and age. However, patients with early postoperative exercise within 6 days showed statistically better outcomes than patients with postoperative exercise after 7 days. Type C1, 2 fractures showed statistically better results than the type C3 fracture.
CONCLUSION
Stable fixation and early exercise are required to prevent postoperative complications and restore functions of the elbow joint with an intra-articular comminuted fracture of the distal humerus.

Abstract PDF: PURPOSE
To analyze the factors affecting the nonunion of extraarticular proximal tibial fracture and the outcome of nonunion treatment.
MATERIALS AND METHODS
We investigated 51 cases of extraarticular proximal tibial fractures from June 2002 to May 2006. The nonunion rate was assessed in relation to several risk factors and the treatment outcome of nonunion using plate fixation with bone graft was assessed by Klemm and BOrner functional rating system.
RESULTS
6 cases of nonunion (11.8%) was noted among 51 cases, and the risk factors examined, OTA A3 comminuted fracture was associated with a high nonunion rate with statistical significance and initial bone graft had a significant effect in bone healing. Excellent and good results were obtained in 5 cases (83.3%) and bone union was achieved in all nonunion cases.
CONCLUSION
Comminution was found to be an important factor affecting the nonunion in extraarticular proximal tibial fracture, and bone graft in primary operation could reduce the chance of nonunion. Accurate plate fixation with bone graft is a reliable option in nonunion treatment.

Published online April 30, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.2.110

Abstract PDF

PURPOSE
To predict the feature and stability of intertrochanteric fractures with posterior fragment using preoperative 3D computed tomography and to investigate the importance of the posterior fragment in treatment of unstable intertrochanteric fracture.
MATERIALS AND METHODS
15 cases of unstable fractures with posterior fragment which were treated with nail only between October 2006 to August 2007 were classified into 2 groups: study group (5 cases with cannulated screw fixation of posterior fragment) and control group (10 cases without cannulated screw fixation). The average difference of neck-shaft angle, neck screw sliding distance and the complications in the two groups were compared retrospectively after a follow up of at least 3 months.
RESULTS
The average difference of neck-shaft angle in study and control group was 3.8 and 7.5 degree (p>0.05), respectively. The average difference of neck screw sliding distance was 1.6 and 6.6 mm (p<0.05), respectively. Complication which required reoperation was not noted in study group and complications of 3 cases about neck screw lateral protrusion, proximal migration and Z-effect phenomenon were noted in control group.
CONCLUSION
The recognition and fixation of the posterior wall was found to be an important predictive factor in unstable intertrochanteric fracture treatment.

Cause and Treatment of the Nonunion of Femoral Shaft Fracture after Interlocking Intramedullary Nailing: Sung Soo Kim, Sung Keun Sohn, Chul Hong Kim, Myung Jin Lee, Lih Wang; J Korean Fract Soc 2007;20(2):141-148. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.141

Abstract PDF

PURPOSE
To analyze the causes and the clinical results of treatment for the nonunion of femur shaft fractures that occurred after interlocking intramedullary nail fixation.
MATERIALS AND METHODS
We reviewed 19 cases of aseptic nonunion of femur shaft fracture in 174 patients after interlocking IM nailing from March 1999 to February 2004 and followed up for more than one year. First we investigated the factors causing nonunion. For operative options, two methods about exchange nailing and exchange nailing with bone graft were performed. Finally clinical results were analyzed with bone union rate by treatment methods and compared with the nonunion factors statistically.
RESULTS
According to the causes and types of nonunion, we performed larger IM nail change in 10 cases and IM nail change with bone graft in 9 cases. Bone union was achieved in all cases. Average bone union period were 18.5 weeks in exchange group and 16.1 weeks in exchange with bone graft group. There are significant difference between treatment methods statistically (p<0.05). Compared with the nonunion factors, initial open fracture and smoking groups showed late union rate statistically.
CONCLUSION
Based on our analysis, IM nail change is a useful method for nonunion after initial IM nailing in femoral shaft fracture, and additional bone graft that according to the radiologic pattern and stability, especially the fracture gap is also a useful option for nonunion treatment.

Reamed versus Unreamed Interlocking Intramedullary Nailing in the Treatment of Femoral and Tibial Shaft Fracture: Sung Soo Kim, Chul Hong Kim, Myung Jin Lee, Jin Hun Kang; J Korean Fract Soc 2006;19(2):141-146. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.141

Abstract: PURPOSE
To comparative analysis of clincal difference between reamed and unreamed interlocking intramedullary nailing in the treatment of femoral and tibial shaft fractures.
MATERIALS AND METHODS
We reviewed femoral and tibial shaft fracture who were treated with reamed or unreamed nail. They were followed for a minimum of 16 months. Winquist-Hansen and Johner-Wruhs criteria were applied for the classification of the fractures. Retrospectively we evaluated the duration of operation, the amount of bleeding, the first time of callus formation, union time, the time of partial weight bearing, isthmic ratio, complications.
RESULTS
The average duration of operation for femoral fractures with reamed and unreamed nail were 104 minutes, 95 minutes, respectively. And those for tibial fractures were 96 minutes, 87 minutes, and the difference was statistically significant (p<0.05). The amount of bleeding in femoral fractures with reamed and unreamed nail were 360 ml, 223 ml, respectively. And those in tibial fractures were 280 ml, 205 ml, respectively, and the difference was statistically significant (p<0.001). The isthmic ratio in femoral fracture with reamed and unreamed nail were 105.5%, 87.0%, respectively and those in tibial fracture were 106.3%, 85.3%, respectively. There were 2 delayed unions in femoral fractures and 1 delayed union in tibial fracture with unreamed nail, and 1 metal failure in tibial fracture with unreamed nail.
CONCLUSION
Unreamed femoral intramedullary nailing involves fewer steps and less intraoperative blood loss than reamed nailing. There was no statistical difference the first time of callus formation, union time, the time of partial weight bearing. It must be consider that delayed union and metal failure in the unreamed intramedullary nailing due to high grade fracture, lower isthmic ratio, combined with multiple trauma.

Abstract PDF

PURPOSE
The purpose of this study was to analyze the factors influencing the failure of union in the intertrochanteric femoral fractures.
MATERIALS AND METHODS
Authors divided the patients treated with lag screws into two groups, 9 cases of the non-union group and 46 cases of the union group. And analyzed the preoperative, intraoperative and postoperative factors influencing the union.
RESULTS
Age, displacement in AP film after surgery, displacement of lesser trochanter after surgery, superior or anterior position of lag screw, displacement of lag screw and change of neck-shaft angle were significantly higher in the non-union group. Displacement in AP radiograph after surgery and displacement of lag screw were two significant factors by multivariate logistic regression analysis.
CONCLUSION
In case of intertrochanteric fracture treated with lag screw, the probabilities of union failure are increased when the displacement is more than 5 mm in AP plane postoperatively and the sliding of lag screw is more than 10 mm in follow-up.

Cubitus Varus Resulted from Fracture-Separation of the Distal Humeral Epiphysis: Sung Soo Kim, Sang Hwan Park, Kyoung Sik Hwang; J Korean Soc Fract 2001;14(4):769-775. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.769

Abstract PDF: PURPOSE
We tried to find the cause of cubitus varus after treatment of fracture separation of the distal humeral epiphysis.
MATERIALS AND METHODS
We reviewed 13 cases of fracture-separation of the distal humeral epiphysis. Five cases were treated by open reduction and K-wire fixation, 8 cases were treated by closed reduction and K-wire fixation. Six cases of cubitus varus were evaluated.
RESULTS
With the average 27 months(14-96 months) of follow-up, six of 13 cases showed cubitus varus postoperatively and mean carrying angle was -6.7 degrees(range -3~-15 degrees). None of these cases showed the progression of deformity after then. Among the six cases, five cases were treated with closed reduction, and one case with open reduction. Average age of the cubitus varus cases was 31 months (14-60 months). Among the six cases, four cases were Salter-Hams type I and two cases were type II.
CONCLUSION
Incomplete reduction seems to be the cause of cubitus varus in fracture-separation of the distal humeral epiphysis, so the anatomical reduction is important to prevent the cubitus varus.

Varus Stress Test and Percutaneous Fixation of the Lateral Condyle Fracture of the Humerus in Children: Sung Soo Kim, Sang Ki Lee; J Korean Soc Fract 2000;13(4):1053-1060. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.1053

Abstract PDF: PURPOSE
The current study is planned to evaluate varus stress test and a result of percutaneous K-wire fixation in the minimally displaced lateral condyle fracture of humerus in children.
MATERIALS AND METHODS
We have analyzed seven patients of Jakob stage I or II lateral condylar fracture of the humerus clinically and radiologically who were managed with closed reduction and percutaneous K-wire fixation from July 1996 to June 1999. Their ages at the time of injury ranged 2.5 to 11.7 years (average 6.3 years). We checked varus stress view for evaluating fracture stability and treatment plan.
RESULTS
The patients were followed up for average 13 months postoperatively and showed no differences in carrying angle, range of motion and physical activity compared with contralateral elbow. K-wires were removed average 6 weeks postoperatively. The fractures were united at average 5.9 weeks (5-9 weeks). There were minor complications ; one case of bony overgrowth, three cases of bony spur and one case of pin site infection. The treatment results according to Hardacre's assessment were excellent in all cases.
CONCLUSION
Varus stress view is necessary to evaluate the fracture stability and to make treatment plan in minimally displaced lateral condyle fracture, and closed reduction followed by percutaneous K-wire fixation can be used successfully in the cases of unstable Jakob stage I and reducible Jakob stage II.

Volar Perilunate Dislocation: A case report: Sung Soo Kim, Sung Keun Sohn, Dae Hee Lee; J Korean Soc Fract 1999;12(2):440-445. Published online April 30, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.2.440

Abstract PDF

Perilunar dislocation is not a common injury. When it occurs it is usually dorsal. Only a few isolated cases have been reported of volar perilunar dislocation, in which the capitate is displaced volar to the palmar flexed lunate. Like its more common dorsal counterpart, volar perilunate dislocation usually requires either a concomitant fracture of the scaphoid or scapholunate dissociation. Many authors have been proposed the mechanism of injury, forced hyperflexion, hyperextension with supination of the forearm and violent trauma with extensor tendon rupture. The diagnosis is most easily made on the lateral view. Closed reduction using finger-trap traction should be the initial step in management. Although successful treatment has been reported with a closed reduction alone, open reduction is probably indicated in most cases to align and stabilize the bones. We are reporting on a patient of volar perilunar dislocation without a fracture of the scaphoid or scapholunate dissociation of the right hand associated with extensor tendon rupture.

Supracondylar Closing Wedge Osteotomy for Posttraumatic Angular Deformity of Distal Humerus: Methods for Reducing Secondary Deformity: Sung Soo Kim, Sung Keun Sohn, Chul Hong Kim; J Korean Soc Fract 1996;9(3):706-714. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.706

Abstract PDF: The angular deformity of distal humerus is one of the most frequent complication of supracondylar fracture in growing children. The deformity rarely limits function, but corrected by patients request due to cosmetic problem. Many orthopedic surgeons have suggested various operation methods but with high incidence of complications related to these operations, also we often experience secondary deformity after inaccurate osteotomy. Therefore to identify desirable operative method to reduce secondary deformity, a retrospective study of 17 patients operated with angular deformity following distal humerus fracture was carried out in which replanning with isosceles triangle method was done in all cases. The following results were obtained. 1. The complications were two cases of metal failure and one of non union. 2. The basic requirement of closing wedge osteotomy without secondary deformity was that:the center line of isosceles triangle whose apex angle should be identical to the deformity angle and be placed on the concave apex of deformity, should overlap the transverse bisector of hurnerusforearm axes. In inevitable cases, the disparity should be minimized to alleviate secondary deformity. 3. The translation was calculated by the equation of T=Dxsin Î±(T:translation, D:proximal or distal migration of the point of contact of humerus-forearm axes, Î±:angle of the deformity). In conclusion, we think that the deformity may be corrected safely and easily using minute preoperative planning with application of above principle.

Operative Treatment of the Fracture of Patella: Kyu Yeol Lee, Hyung Hwan Lee, Sung Soo Kim, Sung Keun Sohn; J Korean Soc Fract 1996;9(3):622-630. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.622

Abstract PDF: The patella, the largest human sesamoid bone, is important functional component of the knee extensor mechanism and its treatment is considered to be very important because the fracture involvement to the articular surface occures in most of the cases. We report 40 cases of fractures of patella treated with operative methods from January 1990 to June 1995 at the department of orthopaedic surgery, Dong-A university hospital. The results are as follows. 1. Among 40 cases, 29 cases were male and 24 cases were belong to 3rd decade and 4th decade. 2. The most common cause of injury was slip down or fall down. 3. The pattenrs of fracture were transeverse in 21 cases, vertical in 2 and comminuted in 17. 4. The methods of surgical treatment were modified tension band wiring in 33 cases, circumferential wiring in 2, partial patellectomy in 4 and total patellectomy in 1. 5. In patient treated with modified tension band wiring, range of motion of the knee was 128 and mean duration of bone union was 9.2 weeks. 6. Complications were limitation of range of motion in 3 cases, refracture by slip down in 1 case and wire migration in 1 case.

The Treatnent of Fracture and Nonunion of the Carpal Scaphoid: Sung Keun Sohn, Sung Soo Kim, Myung Soo Lee; J Korean Soc Fract 1996;9(2):264-273. Published online April 30, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.2.264

Abstract PDF: The scaphoid fracture is the most common fracture in carpal bones and its incidence of nonunion, avascular necrosis and ostoarthritis is high because of its precarious blood supply and diffculties of diagnosis and treatment. Authors analyzed 14 cases of carpal scaphoid fractures that treated at the Department of Orthopaedic Surgery College of Medicine, Dong-A University from March 1991 to February 1994 The results were obtained as follows 1. The results of treatment were evaluated by Maudsley method. Excellent or good results were 7 of 8 cases in the Herbert screw fixation, 1 of 2 cases in the K-wire fixation and all cases in the conservative treatment and the bone graft. 2. The mean duration of immobilization was no significant difference regardless of the treatment method in fractures. But in nonunions,there was a decreased immbilization time with the Herbert screw fixation as comparing with the K-wire fixation. 3. In fractures, Herbert screw fixation showed early bone union comparing to other treatments. And there was no significant difference of bone union regardless of the treatment method in nonunion.

Treatment of acromioclavicular dislocation by a Phemister method: Sung Keun Sohn, Kyung Taek Kim, Kyu Yeol Lee, Sung Soo Kim, Hyung Hwan Lee; J Korean Soc Fract 1996;9(1):154-160. Published online January 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.1.154

Abstract PDF: Acromio-clavicular joint dislocation occurs when both acromioclavicular and coracoclavicular ligaments are ruptured and brings to deformity, arthralgia and limitation of motion of the shoulder joint. The treatment of complete acromioclavicular dislocation is controversial, and both of the conservative and surgical treatment are reported to be relatively successful. But, conservative treatment have many disadvantages and now rarely advocated. Recently, there are increasing tendencies to treat the acromioclavicular dislocatioll with anatomical reduction of acromioclavicular joint and rigid internal fixation for early movement of shoulder Joint. We report the results of 16 cases of acute acromioclavicular dislocation treated with Phemister or modified Phemister method. The results are as follows. 1. Among 16 cases,14 cases were males and 9 cases were belong to 3rd decade and 4th decade. 2. The most common cause of injuries was slip down. 3. Postoperative difference in coracoclavicular distance on radiogram was 0.1 mm on average. 4. Clinical results were excellent in 14 cases, good in 1 case and acceptable in 1 case. 5. Complications were redislocation in 1 case and K-wire migration in 1 case, but there was no arhritic changes on the affected A-C joint.

Change of Carrying Angle in Fracture of the Lateral Humeral Condyle in Children: The New Radiologic Carrying Angle Measuring Method: Jung Yoon Lee, Sung Keun Sohn, Keyong Taek Kim, Sung Soo Kim, Dong Man Park; J Korean Soc Fract 1995;8(1):140-151. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.140

Abstract PDF

The lateral condyle fracture of humerus in children is the second most common fracture among the elbow fractures. In dealing with this fracture, we have frequently encountered the various complications due to physeal plate and intraarticular involvement. Change of the carrying angle is one of the common complications, but many authors reported different results about the change of carrying angle. Also, it is too difficult to measure the carrying angle during the early stage of the treatment because of cast immobilization, motion limitation of elbow, and wide variations of radiologic carrying angle according to elbow position changes. We performed this study to find the more stable and predictable new radiologic measuring method about the carrying angle, and then analysed the factors affecting the changes of canying angle of the 23 patients of the lateral condyle fractures of the humerus in children who were treated and followed up more than twelve months at the Department of Orhopaedic Surgery, Dong-A University Hospital from May 1990 to April 1993. The results were as follows. 1. Carrying angles by Beals method showed variable values according to the elbow positions, but A-angles by the new measuring method were relatively stable regardless of the elbow positons. 2. Increase of clinical carrying angle was 3 cases, decrease was 9 cases, and ranges of clinical carrying angle change were from -7 degress to 14 degrees. Increase of A-angle was 7 cases, decrease was 4 cases, and ranges of A-angle change were from -10 degrees to +10 degrees. 3. The change of canying angle showed no correlation with Jacob stage, follow up duration, metaphyseal height and interval between injury and treatment. But the incidence and the amount of carrying angle change were increased according to the increased age at injury(r=0.62, P<0.01). 4. There were statistical significant correlation(r=-0.65, p<0.01) and regression between the change of canying angle and A-angle : Y=-0.99X+0.56(Y:change of clinical canying angle,X; A-angle change), (r2=0.42, P<0.01).
