Old Atlantoaxial Rotary Subluxation Associated with High-riding Vertebral Arteries: Arthrodesis Using C1 Lateral Mass Screws and C2 Laminar Screws: A Case Report: Kyeong Hwan Kim, Jin Sup Yeom, Kun Woo Park, Soon Woo Hong, Bong Soon Chang, Choon Ki Lee; J Korean Fract Soc 2007;20(1):90-93. Published online January 31, 2007; DOI: https://doi.org/10.12671/jkfs.2007.20.1.90

To the best of our knowledge, there has been no domestic report on posterior atlantoaxial fusion with segmental screw fixation using C2 laminar screws and C1 lateral mass screws for atlantoaxial subluxation. We report the result of this operation performed in a patient with old atlantoaxial rotary subluxation who required posterior fusion. We chose this technique in this patient because wire fixation was not suitable due to osteoporosis, and transarticular screw fixation and use of C2 pedicle screws were not feasible due to the peculiar bony anatomy of the axis.

Development and Accuracy Test of a Robot-arm Type Image-guided Surgery System for Percutaneous Screw Fixation of the Sacro-iliac Joint: Jin Sup Yeom, Won Sik Choy, Hayong Kim, Jong Won Kang, Kwang Won Lee, Whoan Jeang Kim, Jae Hoon Ahn, Seong Kyu Park, Jong Hwa Won, Hyungmin Kim, Namkug Kim; J Korean Fract Soc 2005;18(2):191-197. Published online April 30, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.2.191

Abstract PDF: PURPOSE
To develop a robot-arm type image-guided surgery system for percuatneous screw fixation of the sacro-iliac joint and to evaluate its accuracy.
MATERIALS AND METHODS
We have developed an image-guided surgery system using a three-dimensional digitizer (Microscribe 3-D G2, Immersion, USA) and a personal computer. The registration error and target localization error at fiducial registration were measured 30 times for each using a phantom made with plastic pelvic bone model (Sawbones, USA). Sixteen 6.5 mm cannulated screws were inserted into four plastic bone models, and the accuracy was evaluated.
RESULTS
The target localization error was 1.46+/-0.47 mm while the registration error was 0.73+/-0.23 mm. All of the 16 screws were inserted well across the sacro-iliac joint, and there was neither cortical breach nor collision between screws or washers.
CONCLUSION
The accuracy of the developed system was similar to that of optical tracker-based navigation systems, and its helpfulness and usefulness was proven with simulation surgery using plastic bone models.

Development of a Computer-assisted Surgery System for Screw Fixation of the Sacro-iliac Joint: Jin Sup Yeom, Won Sik Choy, Ha Yong Kim, Whoan Jeang Kim, Jong Won Kang, Yeongho Kim, Hyungmin Kim, Donghyun Seo, Seok Lee, Jae Bum Lee, Namkug Kim, Cheol Young Kim; J Korean Soc Fract 2003;16(1):1-7. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.1

Abstract PDF: PURPOSE
The purposes of this study were to develop a computer-assisted surgery system for percutaneous screw fixation of the sacro-iliac joint and to evaluate its accuracy.
MATERIALS AND METHODS
We have developed a navigation system composed of an optical tracking device (Polaris, Northern Digital, Canada) and a personal computer. The registration error and target localization error at hybrid registration were measured using a phantom. The errors were measured 30 times for each. Sixteen 6.5 mm cannulated screws were inserted into four plastic bone models (Sawbones, USA), and the accuracy was evaluated.
RESULTS
The registration error was 0.76 +/-0.33 mm, and the target localization error was 1.43 +/-0.42 mm. All of the 16 screws were inserted well across the sacro-iliac joint, and there was neither penetration of the cortical bones nor collision between screws or washers.
CONCLUSION
The accuracy of the developed system was similar to existing ones, and its usefulness and helpfulness was proven with screw insertion into plastic bone models.

Musculo-skeletal trauma of the children: Ha Yong Kim, Kun Young Park, Kwang Won Lee, Jae Hoon Ahn, Jin Sup Yeom, Won Sik Choy; J Korean Soc Fract 2001;14(1):128-134. Published online January 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.1.128

Abstract PDF

PURPOSE
The aim of study was to analyze the patterns of musculo-skeletal trauma of the children.
MATERIALS AND METHODS
From 1997 to 1999, the included for the study were 108 children, who had been admitted for the orthopedic treatment and followed-up. The analysis were done as for 1) children s biological characteristics, 2) the situations of trauma, 3) causes of trauma, 4) types of trauma and 5) locations of fractures.
RESULTS
The average age was 8.5 years at the time of trauma. Sixty cases (56%) were between 5 and 9 years old. Boys were 3 times more common than girls. Second children (61cases, 57%) were more prone to trauma. Half of trauma took place between July and October, and one third of trauma (36 cases, 33%) happened on the street. Ninety eight children (91%) were admitted due to fracture, and supracondyle fracture of humerus was the most common cause(48 cases).
CONCLUSION
Many of accidents could be attributed to children's mischievous play resulted from curiosity and freedom of thought. For the prevention of these accidents, therefore, environment should be restructured from the point of child's view, and not only the design of facility itself but also proper management and education on the facilities should be taken.

Femur Neck Fracture during Closed Nailing of Femur Shaft Fracture: Keun Woe Kim, Ui Seong Yoon, Yong Hoon Kim, Hak Jin Min, Jin Sup Yeom, Young Ho Lee; J Korean Soc Fract 1996;9(4):936-942. Published online October 31, 1996; DOI: https://doi.org/10.12671/jksf.1996.9.4.936

Abstract PDF

Closed intramedullary nailing has become increasingly popular in the management of fractures of the femur because of a high rate of union, a low rate of infection, and excellent return of function. But it requires good availability of equipment and surgeons skill and experience. Iatrogenic femur neck fracture can occur as a complication of closed intramedullary nailing of femur shaft fracture. The authors report five cases of this complication and analyze these five cases in the viewpoint of causal technical errors and suggest some technical points to avoid this complication.
