Antegrade Intramedullary Prebent K-wire Fixation for the 5th Metacarpal Neck Fracture: Tae Hyung Kim, Bo Hyeon Kim, In Ho Jung, Dong Hyun Kim; J Korean Fract Soc 2011;24(1):67-72. Published online January 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.1.67

PURPOSE
To evaluate radiological and clinical results of the antegrade intramedullary prebent K-wire fixation for the 5th metacarpal neck fracture.
MATERIALS AND METHODS
Between January, 2006 and December, 2009, 31 patients with displaced neck fracture of the fifth metacarpal who received antegrade intramedullary prebent K-wire fixation were included in this study. Radiological and clinical outcome evaluations were performed.
RESULTS
All the fractures were completely united. In the oblique radiographs, the average of preoperative angulation was corrected from 38.9degrees to 4.4degrees. The average difference between postoperative and final follow-up was 1.2degrees. Clinical outcomes were satisfactory except for one patient who had sustained ulnar nerve dorsal branch injury during surgery.
CONCLUSION
Antegrade intramedullary prebent K-wire fixation may be preferentially considered as one of the best ways to fix the displaced neck fractures of the fifth metacarpal.

Pediatric Forearm Bone Fractures Treated with Flexible Intramedullary Nail: Suk Kyu Choo, Jin Hwan Kim, Hyung Keun Oh, Dong Hyun Kim; J Korean Fract Soc 2007;20(2):190-195. Published online April 30, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.2.190

Abstract PDF: PURPOSE
To determine the usefulness of flexible intramedullary fixation in pediatric forearm diaphyseal fractures.
MATERIALS AND METHODS
We reviewed 22 cases of forearm diaphyseal fractures treated with flexible intramedullary nail and K-wire. The radiographic assessment was based on the time to union, maintenance of reduction and angular deformity. The functional outcome was assessed with the range of motion and complications at last follow up.
RESULTS
Average length of follow up was 13.9 months with mean age of 10.8 years and the time to union was 5.2 weeks. There were no angular deformity and fuctional results were excellent in all cases. There were 5 cases of soft tissue irritation of nail insertion site as post operative complication which was resolved after nail removal.
CONCLUSION
Flexible intramedullary for pediatric forearm bone fractures is an effective and safe method which gives a good functional outcome.

The significance of distal radioulnar joint injury in distal radius fracture: Jin Woo Kwon, Sung Ho Shin, Won Ho Jo, Dong Hyun Kim; J Korean Soc Fract 2002;15(2):251-257. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.251

Abstract PDF: PURPOSE
To evaluate the effectiveness of operative treatment in distal radius fracture with distal radioulnar joint injury. MATERIAL AND METHOD: From January 1992 to January 2000, 66 cases of distal radius fracture with distal radioulnar joint injury who had been treated with conservative or operative methods were analyzed the final state of radius articular surface and distal radioulnar joint.
RESULT
In operatively treated cases(42 cases), the average of volar tilt was 3.74 degrees, ulnar inclination 21.9 degrees, radial length 9.74mm. In conservatively treated cases(24 cases), The average of volar tilt was 1.75 degrees, ulnar inclination 15.1 degrees, radial length 7.67mm. The state of distal radioulnar joints were as follows; In operatively treated cases, anatomical reduction 37(88%), joint widening 5, In conservatively treated cases, anatomical reduction 17(70%), joint widening or ulnar impingement syndrome 7.
CONCLUSION
In treatment of distal radius fracture with distal radioulnar injury, operative treatment is probably more effective in restoration of radius articular surface and distal radioulnar joint healing.

Treatment of the Clavicle Lateral End Fracture by Kirschner wire and Wire fixation: Jin Woo Kwon, Seung Ho Shin, Won Ho Cho, Woo Se Lee, Ki Hwan Kim, Dong Hyun Kim, Chun Ho Kim; J Korean Soc Fract 2001;14(2):214-222. Published online April 30, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.2.214

Abstract PDF: PURPOSE
The purpose of this study is to evaluate the effectiveness of Kirschner wire and additional wire fixation in clavicle lateral end fractures.
MATERIALS AND METHODS
We reviewed 14 cases that were treated by Kirschner wire and wire fixation from January 1997 to May 1999 and followed up for more than 1 year. Average age was 42 years old(male 6, female 8). The fractures were classified according to Jager and Breitner classification : 2 cases of type 1, 5 of type 2a, 5 of type 2b, 2 of type 3. We used 3 types of fixation method : First, interfragment Kirschner wire and wire fixation in simple fracture. Second, first method was reinforced with transacromial Kirschner wire fixation in simple, but osteoporotic bone. Third, fracture was fixed by transacromial Kirschner wire and wire fixation in intraarticular or comminuted fracture.
RESULTS
Bony union was obtained in all cases with average duration of 10 weeks. The functional result of shoulder was evaluated by the scoring system of Rowe : exellent 8, good 5, fair 1 case. The complications were pin migration 2, pin infection 1, shoulder LOM 3, traumatic acromioclavicular joint arthritis 2 cases.
CONCLUSION
Appropriate use of three types of Kirschner wire and wire fixation technique according to location of fracture, degree of comminution can improve bony union rate and shoulder function.

Metal failure after compression plate fixation in femoral shaft fracture: Sung Ho Han, Bo Kyu Yang, Chi Hong Kim, Tae Won Ahn, Dong Hyun Kim; J Korean Soc Fract 1998;11(4):732-737. Published online October 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.4.732

Abstract PDF: Intramedullary nailing is one of the most available method in the treatment of femoral shaft fracture. Recemtly compression plate is not widly used. Inapproriate technique using compression plate lead to metal failure. The purpose of this study is to analyz the clinical feature, cause and treatment of metal ailure in femoral shaft fracture. We analyzed 6 cases of metal failure from Jan. 1990. to Dec. 1996 and obtained the following results. 1. Type of fracture were Winquist-Hansen Type I in 1 case, Type-II 3 cases, Type III 2 cases. 2. The interval between initial poeration and metal failure was 11 months on average, ranging from one to twenty months. 3. Metal failure occurred as plate breakage in 4 cases, plate bending and loosening in 2 cases. 4. Cause of metal failure after compression plate fixation presumed to be comminuted fracture in 5 cases, early weight bearing in 3 cases, remaining bone defect in 4 cases, inadequate surgical technique in 4 cases and empty plate hole in 4 cases. 5. Treatment of metal failure after compression plate fixation were intramedullary nailing with bone graft in all cases. Accturate preoperative evaluation of fracture site, fracture pattern, and appropiate selection of metal device necessary for the prevention of metal failure.

Fracture of the Coracoid Process: Sung Ho Hahn, Bo Kyu Yang, Chi Hong Kim, Tae Won Ahn, Dong Hyun Kim; J Korean Soc Fract 1996;9(4):1085-1089. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.1085

Abstract PDF: Fractures of the coracoid process arf rare and those associated with a complete acromioclavicular separation and clavicular shaft fracture are even more rare. The mechanism of injury may be by direct trauma or by avulsion when there is sudden and violent contraction of the biceps, corachobrachilalis, and pectoralis minor muscle. The fracture occurs most commonly through the base. Conservative treatment can produce good result. Unusually open reduction is indicated for marked displacement associating acromioclavicular dissociation or compiession of the brahial plexus. The authors report 2 cases of coracoid process fracture. one case combined with acromioclavicular separation and the other with fracture of clavicular mid shaft.
