Two-part and Three-part Fractures of the Proximal Humerus Treated with the Polarus Interlocking Nail: A Comparison of Fracture Types: Kyu Cheol Noh, Yung Khee Chung, Kook Jin Chung, Sung Ku Hong; J Korean Fract Soc 2006;19(2):182-187. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.182

PURPOSE
To evaluate the radiographic and clinical outcomes of patients with displaced proximal humerus fractures (two-part and three-part) treated with the Polarus interlocking nail, comparing their fractures types.
MATERIALS AND METHODS
There were 22 patients with displaced proximal humerus fractures. There were 10 surgical neck (SN) and 1 anatomical neck (AN) two-part fractures and 10 greater tuberosity/surgical neck (GT/SN) and 1 GT/AN three-part fractures. All patients were surgically treated solely with the Polarus interlocking nail using a closed technique. Functional assessment was obtained using the American Shoulder and Elbow Surgeons (ASES) score, which grade outcomes as excellent (>75), satisfactory (50~75), poor (<50) results. Radiographic outcome measurements included fracture alignment (neck-shaft angle), loosening of screw, fixation and hardware failure, and malunion and nonunion.
RESULTS
Overall, the average ASES score was 80.2 (range 46.0 to 98.0). There were 15/22 (68.2%) excellent, 6/22 (27.3%) satisfactory, and 1/22 (4.5%) poor results. All shoulders healed radiographically without evidence of avascular necrosis of the humeral head. When comparing patients with two-part fractures (n=11) with patients having three-part fractures (n=11), there were statistically significant differences with ASES outcome measures (p<0.05). But, there were no statistically significant differences in age-related analysis (p>0.05).
CONCLUSION
Both displaced two-part fractures and three-part GT/SN fractures can have above satisfactory functional and radiographic outcomes with the Polarus interlocking nail using a closed technique. Even though displaced three-part GT/SN fractures in elderly osteopenic patients (>60 years), we treated successfully with the Polarus interlocking nail.

The Surgical Reconstruction of Osteoporotic Vertebral Fractures: Suck Woo Kim, Yung Khee Chung; J Korean Soc Fract 2001;14(1):30-36. Published online January 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.1.30

Abstract PDF

PURPOSE
The purpose of this study is to analyze the surgical results of 11 patients who underwent posterior instrumentation and anterior interbody fusion using titanium mesh vertebral ring(MOSS) in osteoporotic vertebral fracture. MATERIAL AND METHODS: From May 1997 to July 1999, we checked plain radiographs every 3 months and evaluated the change of kyphotic angle, fusion rate, change of clinical, neurologic symptoms and complications of these patients.
RESULTS
There were only average 0.2 degree correction of preoperative kyphotic angle at last follow-up X-ray. However, we confirmed successful bony fusion at nine of eleven patients(82%) and ten of eleven patients(90.9%) got satisfactory clinical results. Four patients with neurologic symptoms have recovered from their original neurologic status. Only one patient reoperated her back because of displacement of surgical device used in previous operation.
CONCLUSION
Among the surgical treatment methods in osteoporotic vertebral fractures, posterior instrumentation and anterior interbody fusion using titanium mesh vertebral ring(MOSS) is recommended as one of the effective surgical methods in severe osteoporotic patients.

Arthroscopic Reduction and Percutaneous Cannulated Screw Fixation for Longitudinal Fractures of Patella: Jung Han Yoo, Yung Khee Chung, Yong Wook Park, Jin Sub Kim, Deuk Soo Jun, Ho Jin Lee; J Korean Soc Fract 2000;13(1):103-108. Published online January 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.1.103

Abstract PDF: A variety of surgical modalities for fractures of patella have been described. We used arthroscopic reduction and percutaneous screw fixation for six cases of longitudinal fracture of patella. Ages of the patients ranged from 25 to 33 years. the postoperative regimen was one week long leg splint for reducing the pain, followed by continuous passive range of motion exercise of the knee including active one and quadriceps strengthening exercise until the full range of motion was gained, with progressive partial to full weight bearing with crutches. The follow-up period was from 12 to 54 monhts. Results were assessed subjectively and objectively with retrograde study. The full range of knee motion was recovered from 20 to 35 days postoperatively, The radiographic bone union was achieved from 31 to 42 days. And all patient had good results according to Lysholm and Gillquist scoring system. We had no experience of complication except one which is prominence of screw end. So, we believed that the arthroscopic reduction and percutaneous cannulated screw fixation for longitudinal fractures of patella is the useful surgical method.

ankle and Tibitalocalcaneal Arthrodesis using Lateral Malleolus as Bone Graft: Yung Khee Chung, Jung Han Uoo, Yong Wook Park, Kang Il Lee; J Korean Soc Fract 1998;11(4):918-923. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.918

Abstract PDF: A variety of surgical approaches and bone grafting techniques for ankle and tibiotalocalcaneal arthrodesis have been described. Wed used transfibular approach and lateral malleolus was used for bone graft. This permitted excellent visualization of the ankle and subtalar joint so that the fusion can readily be achieved under th direct visualization. And also we didn't need to prepare the additional bone graft from another site. Ten ankle fusions and two tibiotalocalcaneal fusions were carried out and reviewed. The average age of the patients was 43 years(range, 27 - 58 years). The average follow-up was 27.8 months(range, 24 - 34 months). We evaluated the clinical and radiological results, and complications. All cases were satisfied and fused. But we experienced one minor complication that was posteroplantar heel pain caused by prominence of cannulated screw head. So, we suggest that this procedure has benefit for ankle or tibiotalocalcaneal fusion.

Retrieval of a Broken Intramedullary Nail after Refracture of Femoral Shaft: A case report: Yung Khee Chung, Jung Han Yoo, Yong Wook Park, Ji Dong Lee; J Korean Soc Fract 1997;10(2):401-404. Published online April 30, 1997; DOI: https://doi.org/10.12671/jksf.1997.10.2.401

Abstract PDF: As the use of intramedullary nail fixation for the long bone fracture has been increased over recent years, so has the rate of reported complications involving intramedullary nail devices. One of the most common complication is fatigue fracture of an intramedullary nail itself if there is delayed union or nonunion of the fracture. The retrieval of the distal segment of broken intramedullary nail had proved to be particularly troublesome. The authors experienced one case of the retrieval of a broken intramedullary nail after refracture of femoral shaft, using the closed method and report this case with review of literatures.

Operative Treatment of Comminuted Fraeture of the Patella: Yung Khee Chung, Jung Han Yoo, Yong Wook Park, Gyu Cheol Roh; J Korean Soc Fract 1996;9(4):970-976. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.970

Abstract PDF

The patella, lying within the quadriceps tendon mechanism and subcutaneous in position, is susceptible to the effects of both direct and indirect trauma. Patella fractures are intra-articular injuries and have a significant effect on knee function. The tension band wiring technique is widely used for treating fractures of the patella and is often the treatment of choice. We reviewed tweenty nine cases of cemminuted fracture of the patella treated with surgical methods from Jan. 1989 to Mar. 1995 and fellowed up more than one year, from the department of of hopedic surgiry, Kangnam Sacred Heart Hospital, Hallym University. The results were as follows: 1. According to the classincation of Bostman, there were 6 cases(20.7%) of type 1.16(55.2%) of II A, 5(17.2%) of II B and 2(6.9%) of III. 2. Of tweenty nine cases, tweenty six(89.7%) were treated by modified tension band wiring with cerclage wiring (MTBW with CW) and three(10.3%) by partial patellectomy with cerclage wiring(PP with CW). 3. Among tweenty six cases treated with MTBW with CW. tweenty one cases(76.9%) revealed a good or exellent result according to the Cincinnati rating system. 4. Especially, among 5 cases of type II B & 2 cases of type III comminuted fracture treated with MTBW with CW, 5 cases(73.4%) revealed good result. We concluded that the use of modified tension band wiring with cerclage wiring for the comminuted fracture of patella has been shown to be a satisfactory method.

A Clinical Experience of Surgical Treatment for Type C of AO Classification of Supracondylar Fractures of the Femur: Yung Khee Chung, Jung Han Yoo, Myung Ryool Park, Baek Yong Song, Yong Wook Park, Jun Tae Kim; J Korean Soc Fract 1995;8(1):22-30. Published online January 31, 1995; DOI: https://doi.org/10.12671/jksf.1995.8.1.22

Abstract PDF: The treatment of supracondylar fractures of the femur remains many problem because of its complications. Particularly, the type C fracture of AO classification causes the traumatic arthritis, limitation of motion, shortening, as well as angular deformity, especially varus. In the past, there has been a reluctance toward treatment of supracondylar fractures of the frmur with internal fixation. But, recently, a trend toward internal fixation has become evident and good results has been reported by several authors. We studied 9 cases of type C of AO classification of supracondylar fracture of the femur at our hospital from January,1989 to February, 1993. The longest follow up was 49 months and the shortest was 12 months, the average being 22.2 months And the results were as follows 1. Age distribution was between 29 and 60 years old, and the ratio between male and females was 5:4. The most common cause of injury was traffic accident. 2. Seven patients were associated with injuries of other parts and the most frequent associated fracture was patellar fracture and the most common associated injury was cerebral contusion. 3. The average time of clincal union was 22 weeks in operative treatment and 13 weeks in conserv alive treatment. 4. In type C AO classification, 6 out of 9 cases treated by anatomical reduction and early motion achieved good to excellent results(50%), but all type C3 fractures is healed in slightly varus position. 5. In conclusion, type C3 of the supracondylar fracture of femur should be reduced to the neutral or slightly valgus position, or the ends of distal cancellous screws should be penetrated the medial femoral cortex because of progressing varus deformity after operation.

Free Fibular Graft to the Segmental Dedect of Long Bone: Yung Khee Chung, Jung Han Yoo, Yong Han Woo; J Korean Soc Fract 1989;2(2):281-287. Published online November 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.2.281

Abstract PDF: Since the documentation of bone graft techniques by Walther in 1820, it has been used widely for the treatment of nonunion, and bone defect due to osteomyelitis, neoplasm, or trauma, and ofr arthrodesis. But many problems are still remained in the treatment of the extensive bone defect. Therefore, varous techniques have evolved to conventional autogenous graft, fresh allograft bone trandsplantation, or free vascularized bone graft. According to Dell P.C. et al, the vascularized grafts were transiently stronger than the conventional nonvascularized ones at six weeks postoperatively because of the differences in the repari mechanisms but thereafter there were no appreciable differences. Therefore, except an inadequate soft tissue bed such as in a chronically infected nonunion, a congenital pseudarthosis, and a previously irradiated or heavily scrred soft tissue bed, we expect good result with conventional nonvascularized fibular graft when there is a segmental bone defect less than 12cm, and/or inadequate fascilities for the microvascular surgery. The four patients with the segmental defect of long bone were treated with conventional nonvascularized fibular graft at Kang Nam Sacred Heart Hospital between July 1980 and October 1988, and are reported with reviews of literatures.

Clinical Observation for the Treatment of Talus Fracture: Yung Khee Chung, Baek Yong Song, Yong Whan Woo; J Korean Soc Fract 1989;2(2):189-193. Published online November 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.2.189

Abstract PDF: Major fractures and dislocations of the talus are uncommon, but the management of this fracture and of the complications is difficult. The results of treatment of this fracture as a whole are generally poor. This is mostly due to frequent complications such as avascular necrosis of the talus. The authors analyzed the 13 cases of the talus fracture and evaluated the results. We obtained the following results; 1. In final results, 3 cases were excellent, 4, cases were good, 3 cases were fair and 2 cases were poor. 2. Avascular necorsis of the talar body occurred in 4 cases of all fractures. 3. Other complications were arthrofibrosis, subtalar arthritis, infection and drsal exostosis of the talar neck.

Treatment of Fracture and/or Dislocation of the Tarsometatarsal Joint, using AO Screws: Two cases Report: Yung Khee Chung, Jung Han Yoo, Baek Yong Song; J Korean Soc Fract 1989;2(1):107-112. Published online June 30, 1989; DOI: https://doi.org/10.12671/jksf.1989.2.1.107

Abstract PDF: Fracture and/or dislocations of the tarsometatarsal joint are rare yet carry such a high potential for chronic disability. These injuries have been frequently followed by poor end results by the failure of timely diagnosis, incomplete reduction, or redislocation after inadequate treatment. These disappointing results have made us to give an aggressive approach for thses injuries consisting of open reduction and temporary rigid internal fixation using AO screws.

A Clinical Experience of Limited Wrist Arthrodesis (Radioscapholunate arthrodesis): Yung Khee Chung, Jung Han Yoo, Baek Yong Song; J Korean Soc Fract 1988;1(1):20-23. Published online November 30, 1988; DOI: https://doi.org/10.12671/jksf.1988.1.1.20

Abstract PDF: The principle of treatment in patient with fracture involving articular surface is necessary for anatomical reduction, rigid fixation and early motion. However, on the occasion of the unsatisfactory results such a post-traumatic arthritis of the wrist joint, in 1981, Watson and coworkers reported the good results by limited wrist arthrodesis for relief of pain and allowance of some range of motion. Recently, we have experienced two cases of post-traumatic arthritis of the wrist joint which was treated by limited wrist arthrodesis, especially, radioscapholunate arthrodesis with good results.
