Treatment of Periprosthetic Femoral Fractures Following Total Knee Arthroplasty: Lih Wang, Kyu Yeol Lee, Chul Hong Kim, Myung Jin Lee, Min Soo Kang, Jin Soo Hwang, Sun Hyo Kim; J Korean Fract Soc 2014;27(1):42-49. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.42

PURPOSE
The purpose of this study is to compare the treatment results of fracture fixations by using two minimal invasive techniques for patients with periprosthetic femoral fractures following total knee arthroplasty.
MATERIALS AND METHODS
We reviewed 36 patients (5 males, 31 females) of periprosthetic femoral fractures whom were treated surgically between January 2005 and January 2011. Mean patient age was 68.9 years (range, 43 to 81 years) old and the follow-up period averaged 41 months (range, 18 to 72 months). Nineteen patients were treated with minimal invasive locking plate fixations (group I) and 17 patients with retrograde intramedullary nailing (group II). Clinical and radiological outcomes in each group were comparatively analyzed.
RESULTS
Successful bone unions occurred in all patients and the mean time to bone union was 3.7 months in group I and 4.2 months in group II. There were no statistical differences between the two groups according to mean operative time and mean intraoperative blood loss. There were also no statistical differences between two groups according to clinical outcomes but the valgus deformity was apparent in group II and radiological outcomes revealed significant differences between the two groups.
CONCLUSION
For the treatment of periprosthetic femoral fractures after total knee arthroplasty, two minimal invasive techniques have shown good clinical results. However, the minimal invasive plate fixation showed better results in the radiological alignments.

Results of the Kapandji Procedure in the AO Type C Distal Radius Fracture in Patients over Age 60: Chul Hong Kim, Sung Soo Kim, Myung Jin Lee, Hyeon Jun Kim, Bo Kun Kim, Young Hoon Lim; J Korean Fract Soc 2012;25(3):191-196. 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.

Clinical Outcome of Surgical Treatment for Intra-articular Distal Humerus Fracture: Myung Jin Lee, Hyeon Jun Kim, Sung Keun Sohn, Kyu Yeol Lee, Sung Soo Kim, Chul Hong Kim, Lib Wang, Hyun Woo Sung; J Korean Fract Soc 2010;23(2):201-205. Published online April 30, 2010; DOI: https://doi.org/10.12671/jkfs.2010.23.2.201

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.

Cause and Treatment of Extraarticular Proximal Tibial Nonunion: Sung Soo Kim, Sung Keun Shon, Kyu Yeol Lee, Chul Hong Kim, Myung Jin Lee, Min Soo Kang, Lih Wang, Im Sic Ha; J Korean Fract Soc 2008;21(4):279-285. Published online October 31, 2008; DOI: https://doi.org/10.12671/jkfs.2008.21.4.279

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.

Classification and Treatment of Unstable Intertrochanteric Fracture according to the Existence of Posterior Fragment : Preliminary Report: Lih Wang, Sung Keun Shon, Kyu Yeol Lee, Chul Hong Kim, Myung Jin Lee, Chul Won Lee, Sung Soo Kim; J Korean Fract Soc 2008;21(2):110-116. 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
To evaluate the result of comparative study about the cases in the fracture of the distal femur treated with plate and screw, dynamic condylar screw, blade plate, retrograde intramedullary nail and external fixator.
MATERIALS AND METHODS
The AO classification system was used. 84 cases who were preformed operation during the period from March 1996 to May 2002, were included in this study. The mean duration of follow-up was 25 months. According to Sachatzker criteria, we classified the following results to excellent, good, fair and poor.
RESULTS
Type A were excellent or good result when treated with plate and screw, dynamic condylar screw and retrograde intramedullary nail. Type B were excellent or good result when treated with cannulated screw. Type C were excellent or good result when treated with plate and screw and blade plate.
CONCLUSION
We conclude that the most important thing in operation is firmly internal fixation and to obtain this, accurately anatomical reduction and the choice of suitable instrument for the type of the fracture are needed. cannulated screw. Type C were excellent or good result when treated with plate and screw and blade plate.

Surgical treatment using external fixator for unstable intra-articular fracture of distal radius: Chul Hong Kim, Byeong Hwan Kim, Sung Won Lee, Wook Kim; J Korean Soc Fract 2003;16(1):83-90. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.83

Abstract PDF: PURPOSE
To analyze the results of surgical treatment using external fixator for unstable intra-articular fracture of distal radius. MATERIAL AND METHODS: We investigated 38 cases of distal radius fracture from Mar. 1990 to Dec. 2000. The patients were followed up for average 18 months postoperatively. We compared the results of 22 cases, treated with open reduction and internal fixation(ORIF) to the results of 16 cases, treated with ORIF and external fixation. We evaluated the results of the mean loss of radial length, radial inclination, volar tilt and traumatic arthritis according to demerit point rating system above the Fernandez classification IV.
RESULTS
According to demerit point rating system, excellent to good results were obtained in 72.7% at ORIF and external fixator, compared to 43.8% at case of ORIF only. In the last follow up, the mean loss of radial length was 0.6mm in case of ORIF, but 0.4 mm in case of ORIF and external fixator, the mean loss of radial inclination was 2.3 and 1.5 degrees, the mean loss of volar tilt was 2.5 and 2.2 degrees, respectively (p < 0.05). Postoperative complications were developed in 9 cases. Malunion was in 4 cases of ORIF and external fixator, in 2 cases of ORIF. Metacarpal bone fracture was in 1 case of ORIF and external fixation. Traumatic arthritis was in 2 cases of ORIF.
CONCLUSION
Open reduction and internal fixation combined with external fixation was thought to be a better method than open reduction and internal fixation for the treatment of unstable intra-articular fractures of the distal radius of the Fernandez classification IV and IV, because that was more comfortable and convenient to patients and was useful to prevent late displacement.

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.
