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.

Treatment of Infected Nonunion of the Tibia Using the Ilizarov Apparatus: Duck Yun Cho, Eun Sung Koh, Suk Cho Kong; J Korean Soc Fract 1996;9(3):665-673. Published online July 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.3.665

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.

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

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.
