Breakage of Reamer during Tibia Intramedullary Nailing: A Case Report: Ho Yoon Kwak, Jin Su Kim, Ki Won Young, Joo Won Joh, Sae Min Hwang; J Korean Fract Soc 2013;26(4):333-337. Published online October 31, 2013; DOI: https://doi.org/10.12671/jkfs.2013.26.4.333

The reamer crack, followed by breakage at its distal part occurred during intramedullary nailing of tibial shaft fracture. The broken reamer was trapped in the intramedullary canal, making it very difficult to pull out. We successfully extracted the broken reamer by retrograde impaction through the fracture site and completed intramedullary nailing procedure. Thus, we present this case with a review of the literature.

External Fixator and External Fixator Supplemented with K-wire in the Treatment of Distal Radius Fractures: Sang Wook Bae, Ho Yoon Kwak, Baik Yong Song, Young Joo Ahn; J Korean Fract Soc 2005;18(3):311-316. Published online July 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.3.311

Abstract PDF: PURPOSE
To evaluate the differences of the outcome between external fixator and external fixator supplemented with K-wire in the treatment of distal radius fractures.
MATERIALS AND METHODS
Twenty-one cases which underwent external fixation (external fixation group) and 28 cases, external fixation supplemented with K-wire (external fixation with K-wire group), were analyzed. Radial length, radial inclination and volar tilt were compared in preoperative, immediate postoperative radiographs, and radiographs after removal of external fixator between two groups. And functional outcome including flexion, extension, pronation and supination of wrist were compared between two groups and wrist pain, as well.
RESULT
Radial length and radial inclination in the postoperative radiographs and radiographs after removal of external fixator showed no difference between two groups, but volar tilt of external fixation group measured 2.1+/-4.2 degrees, 1.3+/-3.8 degrees and external fixation with K-wire group, 8.8+/-2.3 degrees, 8.5+/-2.4 degrees respectively, so that external fixation with K-wire group showed better reduction and maintenance. Wrist flexion and extension about postoperative 6 months measured 25.6+/-8.2 degrees, 25.1+/-10.2 degrees, respectively, in external fixation group and 42.5+/-15.2 degrees, 33.6+/-9.5 degrees in external fixation with K-wire group, so that external fixation with K-wire group showed better functional results.
CONCLUSION
In the treatment of distal radius fractures, to obtain better reduction and function result, external fixations supplemented with K-wire need to be taken into consideration.

Non-operative Treatment of Lateral Malleolar Fracture using Ankle Brace: Nam Hong Choi, Ho Yoon Kwak, Baik Yong Song, Sang Wook Bae, In Mook Lee, Do Hyun Kim; J Korean Soc Fract 2003;16(3):363-369. Published online July 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.3.363

Abstract PDF: PURPOSE
The purpose of this study was to evaluate the outcome of conservative treatment for minimal displaced lateral mallolar fracture using ankle brace.
MATERIALS AND METHODS
Eleven patients (eleven ankles) underwent conservative treatment with ankle brace for 8 weeks with full weight bearing ambulation. Inclusion criteria were minimal displacement (<3 mm) of fracture, no or mild tenderness or swelling on medial malleolar area and no lateral shift of talus. The patients were evaluated with AOFAS (the American Orthopedic Foot and Ankle society) Ankle-Hindfoot scale.
RESULTS
Average follow up was 103 weeks (36~192). All cases had normal range of motion of ankle. The average score of AOFAS Ankle-Hindfoot scale was 95 points.
CONCLUSION
The advantages of conservative treatment with ankle brace were early return to daily activity and work, comfort to the patients and a short period of rehabilitation. Conservative treatment with ankle brace for minimal displaced lateral malleolar fracture is recommended.

The Posterior Plate for Distal Fibular Fixation: Beak Yong Song, Ho Yoon Kwak, Sang Wook Bae, Kyung Tai Lee, Nam Hong Choi, Jin Young Kim, Ho Jun Kim; J Korean Soc Fract 2001;14(1):79-84. Published online January 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.1.79

Abstract PDF: PURPOSE
To evaluate the clinical results between the posterior and lateral plate for distal fibular fixation in the bimalleolar, trimalleolar fracture and isolated lateral malleolar fractures with more than 3 mm of displacement.
MATERIALS AND METHODS
We reviewed 69 cases treated by open reduction and internal fixation with the posterior or lateral plate for distal fibular fractures in the bimalleolar, trimalleolar fractures and isolated lateral malleolar fractures with more than 3mm of displacement. The follow up period was more than 12 months.
RESULTS
In the posterior plate group, radiographically there were no intraarticular screw, loss of fixation, nonunion and malunion, but 2 cases of distal tibiofibular synostosis were developed. In physical examination, there were no wound complication, palpable screws, peroneal tendinitis and limitation of motion, but 2 patients who had distal tibiofibular synostosis complained of mild discomfort after walking.
CONCLUSION
The posterior plate for distal fibular fixation is thought to be a favorable method and can be recommended as the fixation modality of choice regardless of level of fracture, because of increased biomechanical stability and few complication.

The Treatment of Danis-Weber Type B Fractures of the Distal Fibula by Multiple Kirschner Wires Fixation: Ho Yoon Kwak, Baik Young Song, Sang Wook Bae, Nam Hong Choi, Jin Young Kim; J Korean Soc Fract 2000;13(3):529-536. Published online July 31, 2000; DOI: https://doi.org/10.12671/jksf.2000.13.3.529

Abstract PDF

PURPOSE
To evaluate the accuracy of reduction and stability of fixation according to different methods of internal fixation for the Danis-Weber classification type B fractures of the distal fibula. MATERIAL AND METHODS: Seventy-three cases with follow up of average 13 months were divided into three groups: plate fixation(Group I, 36), more than two lag screws fixation (Group II, 13) and multiple K wires fixation with less than one lag screw(Group III, 24). We measured the bimalleolar angle and axial displacement of the fracture ends for radiographic evaluation, and used the Meyer's classification for clinical evaluation.
RESULTS
There was significant difference of postoperative fibular shortening between group I(0.44mm) and III(0.17mm) on the anteroposterior view(p=0.003), but no difference of it on the lateral view. The changes of bimalleolar angle and the increment of fibular shortening showed no significant difference among three groups.
CONCLUSION
Multiple K wires fixation combined with less than one lag screw for Danis-Weber type B fractures of distal fibula demonstrated that it provides accurate reduction and stable internal fixation.

Treatment of Long Spiral Comminuted Fracture of the Shaft of Humerus Using Multifilament Cerclage Cables and External Fixator: Ho Yoon Kwak; J Korean Soc Fract 1998;11(4):958-963. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.958

Abstract PDF: Long spiral comminuted fracture of the shaft of humerus, which is more common today than in the past, is one of the most difficult fractures to treat and remains challenge to orthopaedic surgeons. From Feb. 1995 to Nov. 1996, We have treated 6 cases of long spiral comminuted fracture of the shaft of humerus by internal fixation with multifilament cerclage cables combined with external fixation, and achieved bony union in all cases at average 4 months and good clinical results. The advantages of this operation method are minimal damage to the adjacent soft tissues by relatively small exposure, minimal internal instrumentation, early mobilization and the need of secondary operation for implants removal is eliminated. Also, It may be suggested that the author's operative method is one of the solutions for treatment of long spiral comminuted shaft fracture of humerus involving metadiaphyseal area.
