Interposition of Extensor Pollicis Longus Tendon in Smith's Fracture in a Child: A Case Report: Seung Ju Jeon, Haeng Kee Noh, Do Yeon Kim, Sung Hoon Jung, Jun Beum Shin, Ho Seung Jeon; J Korean Fract Soc 2013;26(1):65-68.

Abstract PDF: Entrapment of the extensor pollicis longus tendon is reported rarely on Smith's fractures in children. In our case, a 15 year old boy with Smith's fracture received treatment of closed reduction at another hospital. When he visited our hospital, a wide gap at the fracture site was detected on radiograph and the thumb movement was limited. We have doubt the entrapment of the soft tissue, especially the tendon. We decided on open reduction. In the operation field, entrapment of the extensor pollicis longus tendon at the gap of the fracture site was found through dorsal approach. In addition, fracture treatment with K-wire fixation after reduction of extensonr pollicis longus tendon reduction was done. Therefore, we report this case with a review of the literatures.

Double Tension Band Wire Fixation for Unstable Fracture of the Distal Clavicle: Kyeong Seop Song, Hyung Gyu Kim, Byeong Mun Park, Jong Min Kim, Sung Hoon Jung, Bong Seok Yang; J Korean Fract Soc 2009;22(1):24-29. Published online January 31, 2009; DOI: https://doi.org/10.12671/jkfs.2009.22.1.24

Abstract PDF: PURPOSE
To evaluate the clinical results after operative treatment with the double tension band wire fixation in Neer type II and III distal clavicle fractures.
MATERIALS AND METHODS
Ten patients with type II and III distal clavicle fractures were evaluated, who operated with double tension band wire fixation technique, from Febrary 2007 to June 2008, and could be followed-up for more than 1 year after operation. Postoperative assessments were evaluated on plain x-ray, pain, and clinical finding according to the functional criteria by Kona et al.
RESULTS
Average duration from operation to fracture union was 8 weeks in all cases. There were 8 excellent and 2 good results. It was no other significant complications such as K-wire migration, breakage, infection, and AC joint arthritis.
CONCLUSION
Double tension band wire fixation technique seems to be an effective method for type II or III distal clavicle fracture with multiple compressive axis, without injury of the AC joint and loosening of the fixation.

Stripping of the Hexagonal Recess in the Process of LCP (Locking Compression Plate) Removal: Jong Keon Oh, Chang Wug Oh, Hoon Jung, Kwon Jae Roh, Tae Ho Kim; J Korean Fract Soc 2006;19(2):283-287. Published online April 30, 2006; DOI: https://doi.org/10.12671/jkfs.2006.19.2.283

PURPOSE
To report the difficulties in the process of locking head screw removal due to the stripping of the hexagonal recess of the screw head.
MATERIALS AND METHODS
We have removed 113 5.0-self tapping locking head screws and 202 3.5-self tapping locking head screws from 34 patients with fracture healing and 5 patients complicated with infection. All of the operations were done by one surgeon. All the screws were placed with the use of torque limiting attachment or driver.
RESULTS
All of 113 5.0-self tapping locking head screws were removed without difficulties with an usual manner. 21 out of 202 3.5-self tapping locking head screws were removed with many difficulties due to the stripping of the hexagonal recess. 3 screws were removed successfully with the use of conical extraction screw. 12 screws were taken out by further stripping and destruction of the screw head. In 6 situations where the only one screw was left stripped, the plate was bent around the stripped screw and then it was removed by turning the plate as a handle. One screw was removed with the partial breakage of the near cortex upon lifting the plate after failed attempt of using conical extraction screw.
CONCLUSION
Although we have followed the guidelines at the time of insertion we have experienced difficulties in the removal of 3.5 locking head screws due to the stripping of the hexagonal recess. Care should be taken at the time of removal of the locking plate especially for the 3.5 locking screws.

Atlanto-occipital Assimilation Can be Misdiagnosed as Atlantoaxial Dislocation: A Case Report: Kwang Bok Lee, Sang Rim Kim, Kwang Hoon Jung; J Korean Fract Soc 2005;18(4):470-473. Published online October 31, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.4.470

Abstract PDF: We present a rare case that atlanto-occipital assimilation can be misdiagnosed as C1-2 anterior subluxation. This is a lack of familiarity in orthopedic surgeon that was not used to manage the upper cervical spine injury. So the treatment of this entity need to get careful diagnosis and attention.

The Effect of Bone Connecting Powder on Stimulation of Bone Healing (Biomechenical study using double-blind method): Kyu Hyun Yang, Sung Hoon Jung; J Korean Soc Fract 2002;15(2):264-270. Published online April 30, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.2.264

Abstract PDF: PURPOSE
To investigate the effect of bone connecting powder on stimulation of bone healing, we performed a biomechenical study using the rats in double blinded method.
MATERIALS AND METHODS
One hundred ten-week-old korean rats were used. We performed closed intramedullary nailing with #2 Kirschner wire on the right femur and then transverse fracture was created on the right femoral shaft. The rats were divided into two groups in double blind method, one group was bone connecting powder feeding group and the other was placebo group. The rats were euthenized four weeks after fracture. We measured the ultimate load, stiffness, ultimate stress by 3-point bending test using electromechanical testing machine. The code used for double blinded method was disclosed after biomechanical test.
RESULT
Biomechenical test was performed at four weeks after fracture, in which there were 38 rats alive in the study group and 36 rats alive in the placebo group. There were 5 nonunion in study group, 7 in placebo group. The ultimate load was 40.77 +/- 28.09N for study group, 32.39 +/-25.10N for placebo group and stiffness was 49.98 +/- 45.32N/mm, 40.52 +/-36.61N/mm respectively. We calculated the ultimate stress to correct the difference from each bone's shape and thickness and it was 11.017 +/- 10.170N/mm 2 , 6.659 +/-6.670N/mm 2 for each other(p=0.041).
CONCLUSION
On the basis of this biomechenical study, it may be concluded that fracture healing is stimulated by bone connecting powder.
