Double Plating of Proximal Tibial Fractures Using Minimally Invasive Percutaneous Osteosynthesis Technique: Chang Wug Oh, Jong Keon Oh, In Ho Jeon, Hee Soo Kyung, Il Hyung Park, Byung Chul Park, Woo Kie Min, Ji Ho Lee; J Korean Fract Soc 2005;18(3):250-255. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.250

OBJECTIVES
To evaluate the results and its efficacy of double plating for proximal tibial fractures using minimally invasive percutaneous osteosynthesis (MIPO) technique. MATERIAL & METHODS: Twenty-three fractures, followed-up more than 1 year, were included in this retrospective study. There were 18 men and 5 women, and the mean age was 53.5 years-old. According to the AO-OTA classification, five were 41A, 13 were 41C, and 5 were 42. There were four open fractures (grade I- three, grade III A-one case). The plates were fixed on the medial and lateral sides of tibia with MIPO technique. Functional and radiographic results were evaluated by the modified Rasmussen system.
RESULTS
All fractures healed without bone graft, and the mean period for fracture healing was 19.3 weeks (range, 10~32 weeks). All other patients had excellent or good clinical or radiological results, except for two patients of a fair clinical result after a combined injury. Complications included one case of shortening (1 cm) and two cases of mal-alignments (varus less than 10 degrees). There was one case of superficial infection, but no patient showed deep infection.
CONCLUSION
Double plating using MIPO technique can provide favorable results in the treatment of proximal tibial fractures.

Internal Bone Transport in the Management of Tibial Bone Defects: Chang Wug Oh, Woo Kie Min, Hee Soo Kyung, Il Hyung Park, In Ho Jeon, Byung Chul Park, Poong Taek Kim, Young Heon Sohn; J Korean Fract Soc 2005;18(1):36-42. Published online January 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.1.36

Abstract PDF

PURPOSE
To retrospectively review the results of internal bone transport in the management of tibial bone defect using ilizarov fixator.
MATERIALS AND METHODS
We treated 39 cases of tibial bone defect (16 of traumatic bone loss, 23 after treatment of osteomyelitis). The mean age of index procedure was 33.8 years (range, 13~66 years), and all of them had follow-up study for a mean of 3.5 years (range, 1.6~8 years). The mean transported amount was 6.3 cm (range, 2.7~20 cm), and the external fixator was removed after 345 days (range, 120~700 days). The mean external fixation index was 60.3 days/cm (range, 13.1~121.3 days/cm).
RESULTS
Primary union of distraction and docking site was achieved in all, but two patients had failure in union of docking site. Functional results showed 6 excellent, 19 good, 10 fair, and 4 fair. The patients under age 20 showed better functional outcomes than the others. Among 73 complications (incidence, 1.87 cases/ patient), 27 of major complications with residual sequelae occurred in 20 patients. The residual sequelae were more common in the patients who had the concomitant injuries in the same leg.
CONCLUSION
Internal bone transport can solve the large amount of tibial bone defect. However, the complications are not uncommon, which might be related to the concomitant injures in the same leg.

Published online July 31, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.3.224

Abstract PDF

PURPOSE
Despite of various treatment methods, proximal tibial fractures are common injuries that may be associated with poor outcomes and high rates of complications. To improve this, percutaneous plating technique was performed in the proximal tibial fractures.
MATERIALS AND METHODS
Twenty-four proximal tibial fractures (AO 41A; 5, AO 41C; 12, AO 42; 7) were treated by percutaneous plating with either or both sides without bone graft. One was open fracture.
RESULTS
All fractures were healed. The average time for fracture healing was 16.5 weeks (range, 8~24 weeks). Complications included a 1cm shortened case and two mal-alignments; a 6 degree valgus case and 5 degree varus case. There was one case of superficial infection, which healed after plate removal. But, there was no deep infection. Results were evaluated by modified Rasmussen score system, all patients had excellent or good result.
CONCLUSION
Minimally invasive percutaneous plating technique can provide favorable results in the treatment of proximal tibial fractures.

Published online April 30, 2004; DOI: https://doi.org/10.12671/jkfs.2004.17.2.148

Abstract PDF

PURPOSE
This is a retrospective study to analyze the results of unreamed intramedullary nailing in grade III tibial open fracture.
MATERIALS AND METHODS
Twenty-nine Gustilo-Anderson grade III tibial open fractures fixed with unreamed tibial nail were followed more than one year. Primary union rate, union time, infection, conversion to external fixation, ankle and knee function according to different grade of open, fracture level, AO classification, and muscle flap were evaluated.
RESULTS
Primary union was achieved at sixteen fractures. There were three delayed union that achieved union twenty week after primary operation. And eight undergone secondary bone grafts which were done after inflammation sign subcided. Complications about infection were in five cases. Two cases were unable to maintain internal fixation due to deep infection, and three of superficial infection were treated with repeated debridement and antibiotics use.
CONCLUSION
In grade III tibial open fracture, unreamed nailing with early soft tissue reconstruction and early prophylactic bone graft can be a good treatment.

Treatment of Nonunion in the Long Bone with Low Intensity Pulsed Ultrasound (LIPUS) and LASER: In Ho Jeon, Chang Wug Oh, Sung Jung Kim, Hee Soo Kyung, Il Hyung Park, Byung Chul Park, Joo Chul Ihn, Jun Young Yeo; J Korean Soc Fract 2003;16(2):177-185. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.177

Abstract PDF: PURPOSE
Low-intensity, pulsed ultrasound (LIPUS) has demonstrated a stimulation and acceleration of the normal fracture-repair process in cellular bases as well in animal and human models. In this study, the adjunctive effect of LIPUS and LASER was investigated in established nonunion of the long bones.
MATERIALS AND METHODS
Study group consisted of eight patients to whom conventional bone graft and adjunctive LIPUS and LASER was applied. On the other hand, eight patients in the control group underwent bone graft only. Eleven men and five women were included in this study and the average age of the patients was 41.7 years (range, 19~62 years). Six of the tibias and ten of the femurs met the criteria for established nonunion. The average fracture age, the post-fracture period before the start of LIPUS/LASER treatment, was 502 days.
RESULTS
Seven of the ten nonunions who were treated by LIPUS and LASER healed completely in an average treatment time of 141 days (range, 101~202 days) and otherwise, in control group, five of the eight nonunions healed completely, in 240 days (range, 183~283 days).
CONCLUSION
This clinical study showed a positive effect of LIPUS and LASER on the rate of osseous repair, especially accelerated time to initial callus cortical bridging compared to that of conventional treatment.

Retrograde Intramedullary Nail for Femoral Shaft Fracture with Limited Indications: Sung Jung Kim, Chang Wug Oh, Joo Chul Ihn, Hee Soo Kim, In Ho Jeon, Hee Soo Kyung, Il Hyung Park, Kyung Hoon Kim; J Korean Soc Fract 2003;16(1):45-51. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.45

Abstract PDF

PURPOSE
This is a retrospective study to analyze the results after retrograde intramedullary(IM) nailing in femoral shaft fractures with limited indications.
MATERIALS AND METHODS
Twenty-four femoral shaft fractures(21 patients) were operated with unreamed IM nail(Unreamed femoral nail, SynthesR) in a retrograde method and were followed for more than 1 years. There were 16 men and 5 women, and the mean age at index operation was 41 years (range 18-76 years). In Winquist-Hansen classifications, there were 10 of type I, five of type II, three of type III, and six of type IV. All the patients had associated fractures or injuries, and there were eight ipsilateral tibia fractures, five ipsilateral proximal femoral fractures(including neck and trochanter), four ipsilateral pelvic or acetabular fracture, three bilateral femoral fractures, and one ipsilateral knee injury according to the used indications. In radiological study, we evaluated the time for union, non-unions and malunion, and clinical evaluation with Neer 's criteria was done.
RESULTS
Most fractures(87.5%) were primarily united cases, and the mean time for union was 15.8 weeks(range 12-20 weeks). Three cases of delayed union or nonunion were developed, but a shortening over 1cm or malunion over 10 degrees angular deformity were not found. Evaluating the knee functions, the Neer score was 86.9 in average and all the cases were above satisfactory grade. The average range of knee motion was 120.2 degrees, and the mild knee pain was developed in three cases.
CONCLUSION
The retrograde IM nailing can be a useful option for femoral shaft fractures with limited indications, including ipsilateral fractures of other areas or multiple fractures.

Complications and Affecting Factors for Intracapsular Femoral Neck Fractures Treated by Multiple Pinning: Sung Jung Kim, Shin Yoon Kim, Gi Bong Cha, Chang Wug Oh, Il Hyung Park, Joo Chul Ihn; J Korean Soc Fract 2002;15(2):201-208. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.201

Abstract PDF

PURPOSE
To investigate the relationship between the complications of intracapsular femoral neck fractures treated by multiple pinning and several affecting factors.
MATERIALS AND METHODS
Sixty-eight patients with intracapsular femoral neck fractures were treated by multiple pinning from March 1993 to January 2000 and followed at more than one year. Relationship between the complications such as failure of union, collapse of femoral head due to osteonecrosis of femoral head and several affecting factors including displacement of fracture according to Garden stage, state of reduction, position of screws, time interval from injury to operation, and fracture level were analyzed. The Fisher exact test, chi-square test, and multivariate logistic regression analysis were used to find the relevant factors influencing incidence of complications. Statistical significance was set at p < 0.05.
RESULTS
Position of screw was the most important single factor affecting the results of treatment of intracapsular femoral neck fracture (p=0.046). Moreover, the Garden stage and position of screw were revealed affecting the incidence of complications together with other factors (each p value was 0.028 and 0.027).
CONCLUSION
We considered that satisfactory position of screw was important to reduce complications after multiple pinning for intracapsular femoral neck fracture. And the results of operation also seemed to closely relate with multiple factors including Garden stage and status of reduction.

Effect of injected calcium-sulfate on the consolidation of distraction osteogenesis in rabbit model: Chang Wug Oh, Poong Taek Kim, Byung Chul Park, Il Hyung Park, Hee Soo Kyung, Seung Hoon Baek; J Korean Soc Fract 2002;15(2):271-277. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.271

Abstract PDF: PURPOSE
To investigate whether injection of calcium sulfate salt powder could be used to facilitate consolidation of early & fast distraction osteogenesis.
MATERIALS AND METHODS
Group I was experimental group and Groups II and III were controls. After 3 days of latency period, a small distractor was distracted for a total of 8 mm for 4 days. Calcium sulfate salt powder suspended in carboxymethylcellulose(CMC) solution was injected, whereas CMC media alone was injected in one control group and without intervention in the other control group. Plain radiographs were taken on every weeks. We assesed the bone mineral density(BMD) at 3 and 6 weeks and %BMD was calculated. The rabbits were sacrificed at 6 weeks for histologic examination.
RESULTS
In radiography, the distracted area was consolidated in the experimental group but not in control groups. The % BMD of the experimental group was significantly greater than that of control groups at 6 weeks(p<0.01). In histologic examination, greater amount of newly formed bone was noted in the distraction zone of the experimental group, compared to two control groups.
CONCLUSION
Implantation of calcium sulfate powder can accelerate consolidation in distraction osteogenesis in rabbits.

Effect of Insertion of Bone Graft Substitutes on Consolidation of Distracted Callus: Changes of Radiography & Bone Mineral Density in the Tibia of Rabbits: Chang Wug Oh, Poong Taek Kim, Byung Chul Park, Hae Ryong Song, Il Hyung Park, Jun Ho Baek, Hyung Jin Park; J Korean Soc Fract 2000;13(4):687-695. Published online October 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.4.687

Abstract PDF: PURPOSE
This study was designed to know the effect of calcium-sulfate and xenograft on the distracted callus after lengthening.
MATERIALS AND METHODS
We had operation of subperiosteal osteotomy and external fixation on the tibial diaphysis of young New Zealand White rabbits(2.0-2.5kg); after 5 days of latency period, 7 mm(1mm/day, 2 times/day) of tibial lengthening was reached in a week. At 1 week after lengthening, the 1st experimental group of 7 rabbits received a pellet of calcium sulfate(Osteoset , Wright medical, USA) in the distraction gap, and the 2nd experimental group of 7 rabbits received 5mm2 of xenogrfat(Lubboc ) in the distraction gap. But, the control group of 7 rabbits did not receive any of above materials. We compared three groups with the changes of radiographic findings at every week and bone mineral ratio(DEXA) at every two weeks.
RESULTS
The time to complete consolidation of distraction callus of both experimental group(calcium sulfate;14 weeks, xenograft; 15.4 weeks) was shorter than that of control group(16.9 weeks) in radiographic findings. Maximum value of bone mineral ratio of distraction callus was higher and the time to reach the highest value was also shortened in the both experimental group compared to control group.
CONCLUSION
By use of bone substitutes as like calcium sulfate or xenograft in the distraction callus with external fixator, it may be possible to shorten the consolidation period and the fixator-wearing period.

Intramedullary pressure changes in reamed and unreamed nailing systems: an experimental study in cadaveric femoral bones: Chang Wug Oh, Joo Chul Ihn, Poong Taek Kim, Il Hyung Park, Sung Jung Kim, Chung Hyun Lee; J Korean Soc Fract 2000;13(3):631-637. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.631

Abstract PDF: PURPOSE
This study was designed to investigate whether intramedullary pressure is different in reamed compared with unreamed femoral nailing in cadeveric femoral bones. MATERIALS & METHODS: Eight pairs of fresh-frozen cadaveric femoral bones were studied. The diameter of isthmus was checked from 10mm to 14mm and the length of femur was checked from 35cm to 44cm. Intramedullary pressure was measured in the distal femoral shaft at the supracondylar region. Data were monitored in femoral nailing procedures. We utilized the AO universal nail(reamed) and AO unreamed femoral nail.
RESULTS
Intramedullary pressure increased in the reamed group to 423.8 mmHg(mean pressure) during reaming by starting reamer(9 mm) and in the unreamed group to 290 mmHg(mean pressure) during insertion of nails(p=0.001). In the unreamed groups, the next high intramedullary pressure is 136.6 mmHg during proximal reaming. A statistiscally significant difference in intramedullary pressure was found during the first reaming process in the reamed group compared with the proximal reaming process in the unreamed group(p=0.005).
CONCLUSION
The data indicate that the intramedullary pressure during unreamed nailing process is lower than reamed nailing process. So we can consider that the unreamed nailing in multiple fracture or pulmonary injured patients is a good modalities.

Abstract PDF: PURPOSE
: The purpose of this pater was to evaluate results of double plate osteosynthesis in distal humerus fractures. MATERIAL AND METHOD : From June1995 to August 1998, we reviewed 22 distal humerus fractures. According to the type of fractures(AO classification), 6 and 16 cases were type A and C respectively. According to surgical approach, transolecranon approach was done in 12 cases and triceps split approach in 10 cases. We fixed intercondylar fracture with lag screw and supracondylar fracture with dual plate(2 reconstruction plates or 1 reconstruction plate + 1/3 tubular plate) as right angle. Rehabilitation was started just after postoperative 24 hours with posterior splint, and then increase activity and frequency.
RESULTS
: Average union time was 11.5 weeks. Overall functional results according to the classification of Jupiter and Cassebaum were excellent, good, fair, poor in 8, 10, 3, 1 cases, respectively. According to the age, patients under 50-year-old group revealed slightly superior functional. According to the type of fracture, surgical approach, interval between injury and approach, there were no statistically significant difference between group(p>0.05). There were 5 cases with complications. 1 case was mental failure, 3 cases were ulnar palsy, and 1 case was transient radial nerve palsy.
CONCLUSION
: We consider dual plate osteosynthesis in distal humerus fractures as a good treatment modality, even in type C fractures and old age patients.

Arterial Injuries associated with Fractures or Dislocations around the Knee: Chang Wug Oh, Joo Chul Ihn, Byung Chul Park, Il Hyung Park, Shin Yoon Kim, Hee Soo Kim; J Korean Soc Fract 1999;12(4):865-871. Published online October 31, 1999; DOI: https://doi.org/10.12671/jksf.1999.12.4.865

Abstract PDF: The purpose of this article is to delineate factors important in successful management and subsequent extremity function of the patient with arterial injury associated with fractures or dislocations around the knee. We reviewed 25 cases of arterial injury associated with fractures or dislocations around the knee which were treated at our hospital between 1994 and 1998. As long term results, the salvage rate of the lower limb was related to the extent of the soft tissue damage and the severity of infection, but there was no statistical difference according to the method of vascular surgery(p=0.645). Compared with the salvage rate of the lower limb according to the length of time from injury to vascular reanastomosis, there was no statistical difference between two groups of the patients who were operated within 12 hours and were operated during the time between 12 hours and 24 hours(p=0.084). In view of whether open or closed fractures were combined, 1 I cases(58%) among 19 cases of open fractures and 5 cases(83%) among S cases of close(1 fractures were able to salvage the lower limb, so it could contributes to the sdlvdge rate of the limb. Finally 16 cases(64%) among total 25 cases were able to salvage the lower limb, and its functional outcome was like followings : excellent results were found in 6 cases, fair results in 8 cases, poor results in 2 cases, and amputation in 9 cases(36%). In case of amputation, 3 cases were primarily amputated and 6 cases were amputated secondary to vascular surgery . As long term results, whether open or closed fractures were combined, the teverity of the infection and the extent of the soft tissue necrosis were the factors influencing on the falvage rate of the lower limb. Other factors, such as the difference of ischemic time within 24 hours interval, the site and the method of management of the fractures and the vascular injuries and whether fasciotomy was performed or not were not important factors influencing on the salvage rate of the lower limb.

Treatment of Infected Nonunion with Bone Defect with Ilizarov Lenthening apparatus: Joo Chul Ihn, Byung Chul Park, Il Hyung Park, Hee Soo Kyung, Chang Wug Oh, Jin Hum Cho; J Korean Soc Fract 1998;11(1):91-99. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.91

Abstract PDF: From June 1993 to May 1997, 12 patients aged from 13 to 41 years were treated for infected nonunion with bone defect by the Ilizarov technique. Of 12 cases, 9 cases were tibia and 3 cases were femur. The cuases of nonunion were open comminuted fractures with initial bone loss and bone defect after removal of sequestrum. Infection was managed by radical resection of the infected necrotic bone and insertion of antibiotics mixed cement beads. Bony defects were gradually closed by the Ilizarov's internal bone transport technique, and final equalization of leg length inequality was achieved by means of external lenghthening technique. Corticotomies were performed at the proximal level(7), at the distal level(5). The average optained length averaged 4.8cm in length and healing index averaged 67.4days/cm According to paley and Catagni's callification bony and functional results were either excellent or good execpt I case (nonunion, poor bony result). The complications (devided by paley to 3 categories: problems, obstacles, complications) were pin tract infecton(8), pain(5), mild flexion contracture of joint(1), delayed consolidation(3), soft tissue impingement(2), joint stiffness(3) and nonunion(1). We concluded that Ilizarov techinque was very effective for treatment of infected nonunion with bone defect and soft tissue defect.

Mortality Rate in Older Patients Who Have a Hip Fracture: Joo Chul Ihn, Poog Taek Kim, Il Hyung Park, Shin Yoon Kim, Chang Wug Oh, Jae Hyung Kim; J Korean Soc Fract 1997;10(1):1-7. Published online January 31, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.1.1

Abstract PDF

The significant risk to life associated with the hip fracture has long been recognized, and the reports of poor prognosis are well known with wide range of mortality rates. We retrospectively studied 164 patients(older than 60 years) who had a hip fracture to determine the effects of the age, treatment methods, pre-existing medical condition, operative delay after injury, type of fracture, and others on patient mortality. The summarized results were as follows ; 1. One hundred twenty three patients survived and forty one patients died(overall mortality rate; 25.0%). 2. Twenty one patients died within one year(one-year mortality rate, 12.8%). 3. Mortality was related to age of patient at injury, ASA classification, absense or presence of operative treatment, operation-related complication, which were statistically ignificant (P<0.05). 4. The operative delay after injury did not influence mortality, but we think that it is not signifcant because this study was done retrospectively.

A Clinical Study of the Ankle Fracture with Diastnsis: Ik Dong Kim, Jo Chul Ihn, Pong Tnk Kim, Byung Chul Park, Young Goo Lyu, Il Hyung Park, Chang Hyuk Choi; J Korean Soc Fract 1992;5(2):253-259. Published online November 30, 1992; DOI: https://doi.org/10.12671/jksf.1992.5.2.253

Abstract PDF: The ankle fracture with diastasls of distal tibiofibular joint is caused by an axial loading force with concomitant external rotation and associated with severe ankle fracture in addition to talai subluxation due to rupture of the distal tibiofibular syndesmosis. In order to restore the normal ankle mortise, operative anatomical reduction and temporary stabilization of the syndesmosis is mostily required until early ligament healing is present. Twelve cases among ninety-six cases of the ankle fracture were associated with diastasis and treated in the Department of Orthopedic Surgery, Kyungpook National University Hospital during the period from January, 1988 to May, 1991. We analysed these cases according to injury mechanism, radiographic criterion, the patterns of associated medial and lateral injury and treatment result. The results obtained were as follows; 1. The incidence of trauma was most frequent in 5th decade(5 cases). 2. Diastasls was produced by 3 mechanism according to Lauge-Hansen classification : (pronalion-external rotation : 7, Suplnatlon-external rotation : 3, pronation-Abduction;2). 3. All were associated with fibular fracture : proximal fibular fracture was most common (7cases). 4. All had disruption of the medial structures (medial ligament rupture 3, medial malleolusfracture 9). 5. Although the cases were small, there seems no significant differences between transfixation group and unfixation group when accurate anatomical restoration of the distal tibiofibular syndesmosis was achieved.

Intra-Articular Fractures of the Calcaneus: ORIF via Lateral Approac: Ik Dong Kim, Jo Chul Ihn, Poong Taek Kim, Byung Chul Park, Young Goo Lyu, Il Hyung Park, Sung Jung Kim; J Korean Soc Fract 1992;5(2):199-204. Published online November 30, 1992; DOI: https://doi.org/10.12671/jksf.1992.5.2.199

Abstract PDF: The os calcis is one of the most commonly injured tarsal bone and fractures involving the subtalar joint may cause serious and persistent disabilities. We treated 12 intra-artlcular calcaneal fractures in 11 patients from June, 1998 to April, 1992 by plate fixation after lateral approach. The Sanders fracture classification system was applied to out study which classify the fractures according to the number of the fractured segments and direction of the fracture lines after computerized axial tomography of the posterior facetal joint. The follow-up evaluation included questioning the patient about pain during activity and rest, the ability to walk and stand, range of subtalar motion and ability to return to work according to the assessment sheet for calcaneal fractures of Creighton Nebraska Health Foundationl We experienced 8 excellent and 2 good results among 12 cases and there was little complication.
