Bilateral Malunion and Distal Radioulnar Joint Dislocation after Operative Treatment of Bilateral Galeazzi Fractures in Child: A Case Report: Sang Jin Cheon, Dong Joon Kang, Nam Hoon Moon, Seung Han Cha, He Myung Cho; J Korean Fract Soc 2009;22(4):292-296. Published online October 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.4.292

Abstract PDF: Galeazzi fractures in child is rare and seldom necessary of operative treatment because the result of conservative treatment is good. We present the patient who was a 11-year-old male and fell onto his both hands during a hundred-meter dash. His diagnosis was bilateral Galeazzi fractures and limited open reduction and internal fixation with Kirschner pins was initial treatment at local hospital. After 4 weeks postoperatively, Kirschner pins were removed and rehabilitating exercise was started. After 4 months postoperatively, he was transferred to our hospital due to malunion with severe angular deformities and distal radioulnar joint (DRUJ) dislocation. He was treated with corrective osteotomy. Thus, as in this case, we suggest more careful treatment and observation if conservative method of Galeazzi fracture in child is chosen and consider operative method as treatment according to age and pattern of fracture.

Treatment of Distal Radius Fractures Using the Percutaneous K-wire Reduction-Fixation and External Fixator: Sang Jin Cheon, Ja Gyung Ku, Dong Ho Lee, Hui Taek Kim, Jeung Tak Suh; J Korean Fract Soc 2006;19(2):228-235. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.228

PURPOSE
To analyse the results of treatment of unstable intra-articular distal radius fractures using the percutaneous K-wire reduction-fixation and external fixator.
MATERIALS AND METHODS
A retrospective follow-up study of 22 cases was carried out. With use of the system of AO classification 9 cases were in C1 and 7 in C2, and 6 in C3. The average duration of follow-up for all fractures was 35 months. We evaluated the radiologic results, the functional results according to clinical evaluation scoring system by Green and O'Brien and osteoarthritis grade according to arthritic grading system by Knirk and Jupiter.
RESULTS
Excellent and good results were rated in 17 cases (77%) of all cases. At last follow-up the mean loss of radial length, radial inclination and volar tilt were 1.4 mm, 1.0o, and 1.4o respectively. Also 7 patients had grade I, 1 patient grade II, and 1 patient grade III arthritis.
CONCLUSION
We think that percutaneous K-wire reduction-fixation and external fixation is useful treatment method for the unstable intra-articular distal radius fracture. But severely comminuted AO type C3 fractures would need additional treatments such as open reduction and bone graft to acquire and maintain the articular reduction for better results.

Outcomes Related to Closed Interlocking Intramedullary Nailing for Segmental Tibia Fracture: Jeung Tak Suh, Sang Jin Cheon, Young Gyun Kim, Jung Sub Lee, Choon Key Lee; J Korean Fract Soc 2005;18(3):256-263. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.256

Abstract PDF: PURPOSE
To evaluate the outcomes of twenty-six cases of segmental tibia fracture that were treated by closed interlocking intramedullary nailing. MATERIAL AND METHODS: All cases were followed up for at least 1 year (average 14.3 months). Clinical results were evaluated by Klemm & Borner's scale. We analyzed the average range of the motion of the ankle and knee joint, atrophy of quadriceps muscle and angular deformity at the last follow up. We evaluated complications (new fracture of the tibia, infection, compartment syndrome, nonunion, delayed union, angular deformity and pain of ankle and knee joint).
RESULTS
Results were excellent in 4 cases (15.4%), good in 18 cases (69.2%), fair in 3 cases (11.5%), and poor in 1 case (3.9%). Union was obtained in 25 cases (96.1%) over an average period of 23.3 weeks. Nine cases showed intra-operative or post-operative complications: new fracture of the proximal tibia on the posteromedial side (2 cases), local infection at an entry point (2 cases), compartment syndrome (1 case), deep infection (1 case), and delayed union (3 cases). At the last follow up, angular deformity was found in 4 cases (mean of all deformities, 6 degrees): 3 cases at the proximal fracture site (2 cases of valgus deformity: 5 and 8 degrees and 1 case of varus deformity: 7 degrees) and the other case in the distal fracture site (valgus 5 degrees). Average postoperative range of motion of the knee joint was 123.7 degrees (80~135 degrees). Knee pain or limited motion occurred in 4 cases. The average range of the motion of the ankle joint was 68.1 degrees (60~70 degrees). Limited motion occurred in 4 cases (average, 10 degrees) but no case showed ankle pain.
CONCLUSION
Closed interlocking intramedullary nailing for segmental tibia fracture often results in complications. To minimize these complications, comprehensive evaluation of the fracture, and careful surgical treatment are required.

Treatment of pelvic bone fracture involving the sacrum and sacroiliac joint: Hui Taek Kim, Kyo Min Son, Sang Jin Cheon, Chong Il Yoo; J Korean Soc Fract 2001;14(3):313-322. Published online July 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.3.313

Abstract PDF

PURPOSE
To evaluate the usefulness of early posterior internal fixation(I/F) by cannulated cancellous screw(CCS) in unstable pelvic bone fractures involving the sacrum and sacroiliac joint.
MATERIALS AND METHODS
Sixteen cases were evaluated retrospectively. Classification according to the injury mechanism, using Young's criteria, was as follows: 7 anteroposterior compression, 4 lateral compression, 4 vertical shear and 1 combined mechanism. With respect to treatment, 9 cases were treated by combined anterior external fixation(E/F) and posterior I/F with CCS(7 cases) and transiliac rod(2 cases). Five cases were treated by anterior E/F only, and 2 cases were treated without surgery. We analyzed clinical results using Matta's criteria, and radiologic abnormalities.
RESULTS
The management by posterior I/F with CCS and transiliac rod including anterior E/F has shown superior clinical results(7 satisfactory, 2 unsatisfactory) over the management by only anterior E/F(1 satisfactory, 4 unsatisfactory) or conservative methods(2 unsatisfactory). The rate of malunion and nonunion was also low in the former method in the radiographic analysis.
CONCLUSION
Posterior I/F using CCS is an excellent surgical procedure in the treatment of unstable pelvic bone fracture due to its lessened invasiveness, early applicability, simple surgical technique and its direct effects on the prevention of several complications.

Concomitant Ipsilateral Femoral Neck and Shaft Fractures: Kuen Tak Suh, Sang Jin Cheon, Chong Il Yoo; J Korean Soc Fract 1996;9(2):458-465. Published online April 30, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.2.458

Abstract PDF: Concomitant ipsilateral fractures of the femoral neck and shaft are rare, and present diagnostic difficulties and complex choices as to treatment. At the Department of Orthopedic surgery, Pusan National University Hospital, from April 1987 to June 1998, 18 cases of the concomitant ipsilateral fractures of the femoral neck and shaft had been treeated and followed up for 48.7 months in average (ranging from 12 months to 89 months). Initially one case of the femoral neck fracture was missed, which was a non-displaced fracture. Femoral reck fractures were treated with multiple screws or pins in all cases except two cases treated with recon struction nail. For the femoral shaft fractures, plate and screws were applied in 12 cases, Ender nails in three cases, reconstruction nail in two cases and skeletal traction in one case. Nonunion of femoral shaft fracture was developed in one case treated with skeletal fraction, metal loosening in one case treated with Ender nails, and limited motion of the knee in three cases which had knee injuries. But in our cases, avascular necrosis of femoral head and nonunion of the femoral neck and metal failure were not developed. The key factors of successful treatment for concomitant ipsilateral fractures of the femoral neck and shaft seemed to be careful evaluation of the associated hip injures in felnoral shaft fracture and early anatomical reduction and rigid fixation of fractures with early motion of joints.
