Analysis of Risk Factors for the Posterolateral Articular Depression and Status of Posterolateral Fragment in Lateral Condylar and Bicondylar Tibial Plateau Fractures with Joint Depression: Jung Yun Choi, Yong Woon Shin, Beom Jung Lee; J Korean Fract Soc 2013;26(4):241-247. Published online October 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.4.241

PURPOSE
To evaluate risk factors of posterolateral articular depression and characteristics of the posterolateral fragment in lateral condylar and bicondylar tibial plateau fractures with joint depression.
MATERIALS AND METHODS
We reviewed 48 patients of Schatzker type II and type V (type II 34, type V 14) and evaluated risk factors of posterolateral articular depression according to the posterolateral fragment, fibular fracture, and Schatzker classification. We evaluated the position of articular depression and anterolateral fracture line of the posterolateral fragment and measured anterior to posterior lengths of the posterolateral fragment.
RESULTS
Posterolateral articular depression was found in 20 of 34 cases (59%) with coexisting posterolateral fragment and in 16 of 21 cases (76%) with coexisting fibular fracture. There was a significant difference in the occurrence of posterolateral articular depression with the existence of the posterolateral fragment and fibular fracture (p<0.001). Multivariate regression analysis revealed that fibular fracture increased the occurrence of posterolateral articular depression (odds ratio 24.5, 95% confidence interval 2.2-267.2). Fifty-seven percentage of the anterolateral fracture line of the posterolateral fragment existed posterior to the anterior margin of the fibular head.
CONCLUSION
This study showed that fibular fracture affects posterolateral articular depression in Schatzker type II and V tibial plateau fractures. Selecting a fixation device and performing fracture reduction requires a careful consideration since the anterolateral fracture line of the posterolateral fragment exists posterior to the anterior margin of the fibular head.

Analysis of Risk Factors for Nonunion after Intramedullary Nailing of Femoral Shaft Fracture in Adult: Yong Woon Shin, Yerl Bo Sung, Jeong Yoon Choi, Minkyu Kim; J Korean Fract Soc 2011;24(4):313-320. Published online October 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.4.313

Abstract PDF

PURPOSE
To evaluate the union time and nonunion rate after intramedullary nailing of femoral shaft fracture in adult, we would like to analysis the operation techniques, comminution, contact surface and displacement.
MATERIALS AND METHODS
We reviewed retrospectively 53 patients undergoing femoral intramedullary nailing at least 2 years postoperatively and analysised the union time and nonunion rate by operation techniques, comminution, contact surface and displacement. Patients were operated by either antegrade or retrograde intramedullary nailing.
RESULTS
There were no differences in nonunion rate, the duration of bony union between antegrade and retrograde intramedullary nail groups. Significant differences were found in the duration of bony union between the Winquist and Hansen type I, II and the type III, IV (p<0.05). There were significant differences in the duration of bony union among simple, comminuted, and segmental fracture groups (p<0.05).
CONCLUSION
The union time is affected by not operation techniques and fracture displacement, but Winquist-Hansen classification and number of fracture fragments in intramedullary nailing of adult femoral shaft fracture.

Does Interfragmentary Cerclage Wire Fixation in Clavicle Shaft Fracture Interfere the Fracture Healing?: Jae Kwang Yum, Yong Woon Shin, Hee Sung Lee, Jae Gu Park; J Korean Fract Soc 2011;24(2):138-143. Published online April 30, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.2.138

Abstract PDF

PURPOSE
A technique of cerclage wire fixation in comminuted fracture of the clavicle shaft is thought to interfere the fracture healing, so authors studied radiographically and clinically about the cases of cerclage wiring of the fracture fragments with the plate and screws fixation in the comminuted fracture of the shaft of the clavicle.
MATERIALS AND METHODS
According to following inclusion criteria, total 18 patients (male: 15, female: 3) were investigated; Patients who visited hospital due to clavicle shaft comminuted fracture from February 2005 to April 2009, who underwent surgery utilizing more than 2 cerclage wire fixation for the fragments when open reduction and plate fixation were operated and who could be follow-up over one year. The duration for fracture union, functional outcome and complications were investigated retrospectively.
RESULTS
Radiological bone union was accomplished in average 13.3 weeks (12~16 weeks) and there was no complication such as nonunion, delayed union or infection. Range of motion of ipsilateral shoulder joint was recovered in all patients except one at the final follow-up.
CONCLUSION
The clinical and radiographical results of the plate and screws fixation with cerclage wiring of the fragments in comminuted clavicle shaft fracture showed that the cerclage wiring does not interfere the fracture healing, so authors think that this method is a good alternative operation if it is performed carefully to minimize soft tissue dissection.

Flexible Intramedullary Pin Fixation of Both Forearm Bone Fractures in Children: Young Jin Sohn, Yong Woon Shin, Hyung Jin Chung, Sang lim Lee, Jae Kwang Yum, Yerl Bo Sung, Jong Kuk An, Eul O Choi; J Korean Fract Soc 2006;19(2):271-276. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.271

Abstract: PURPOSE
To evaluate the efficacy of Flexible intramedullary pin fixation in pediatric forearm diaphyseal fractures.
MATERIALS AND METHODS
In this retrospective study, we reviewed 15 cases of forearm diaphyseal fractures operated using flexible intra-medullary nail fixation technique between January 2000 and December 2004. Of these 15 children, there were 11 boys and 4 girls with an average age of 11.6 years (range, 7~15 years). The implants were introduced in the distal radius and proximal ulna in all patients. An average duration of fixation was 5.3 months in the radius, 4.7 months in the ulna. After operation, all patient were applied with a long arm cast and the duration of immobilization was 5.2 weeks (range, 4~6 weeks) on average.
RESULTS
All fractures in this series healed with normal range of supination (average 80.0) and pronation (average, 71.6 degrees). Average operation time including anesthesia was 123 minutes and hospital stay was 5.4 days. Time to union was 8.4 weeks on average. Range of motion and functional results were satisfactory in all cases. There were one case of incomplete ulnar nerve injury and two cases of refracture which were treated conservatively without any permanent complication.
CONCLUSION
Flexible intramedullary pin fixation technique is a good method in case of unstable displaced fracture and difficult or failed closed treatment.
