Radiological Assessment for Morphological Diversity of Distal Fibula: Su Young Bae, Jin Hee Yoo; J Korean Fract Soc 2014;27(1):1-9. Published online January 31, 2014; DOI: https://doi.org/10.12671/jkfs.2014.27.1.1

Abstract PDF: PURPOSE
The purpose of this study is to determine whether the morphological consistency of distal fibula could be defined by measurement through radiological assessment as there was doubt regarding the adequacy of anatomical distal fibular plates.
MATERIALS AND METHODS
Plain radiographs and computed tomography (CT) images of 300 cases from 2009 to 2012 were reviewed. The distance from the lateral vertex to the tip of the distal fibula and to the lateral margin of the shaft was measured, respectively, in order to understand the shape of the lateral curve of the distal fibula on plain radiographs. The neutral ridge was defined as a point of the lateral ridge located in the center of the antero-posterior diameter and the distance from the tip of the distal fibula to the neutral ridge was measured for determining the shape of the ridge on CT images. The angle of the lateral and posterior surface of the fibular incisura at the level of the neutral ridge was also measured.
RESULTS
A statistically significant difference in the lateral vertex and margin of the fibular shaft on plain radiographs and distance from the tip of the distal fibula to the neutral ridge, angle of the fibular lateral surface on CT images was observed between male and female. The mean distance from the lateral vertex to the tip of distal fibula was 12.2+/-3.0 mm, to the lateral margin of the fibular shaft was 5.6+/-1.7 mm, distance from tip of the distal fibula to the neutral ridge was 54.9+/-6.4 mm, the fibular lateral surface angle was 52.2degrees+/-9.1degrees, and the fibular posterior surface angle was 32.5degrees+/-9.3degrees.
CONCLUSION
Based on the various radiologic parameters, it was concluded that there was a wide morphological diversity of shape of lateral curve and fibular ridge.

Checkrein Deformity by Incarcerated Posterior Tibial Tendon and Displaced Flexor Hallucis Longus Tendon following Ankle Dislocation: A Case Report: Su Young Bae, Hyung Jin Chung, Man Young Kim; J Korean Fract Soc 2011;24(3):271-276. Published online July 31, 2011; DOI: https://doi.org/10.12671/jkfs.2011.24.3.271

We report a case of 20 year-old man who had unusual equinus and checkrein deformity following dislocation of his right ankle joint. He had been treated with distal tibiofibular screw fixation and external fixation. After removal of external fixator, he had suffered from progressive deformity of foot and ankle. Widening of distal tibiofibular joint and medial clear space was found on radiograph and it was revealed that posterior tibial tendon had been dislocated and incarcerated into the distal tibiofibular joint on MRI. We corrected the deformity with excision of incarcerated posterior tibial tendon, adhesiolysis and lengthening of flexor hallucis longus tendon, reconstruction of deltoid ligament and flexor digitorum longus tendon transfer.

Evaluation of Rotational Displacement of the Posterior Facet on the Sagittal Plane in Computed Tomographic Images of Calcaneal Fractures: Su Young Bae, Yi Kyoung Shin, Jong Oh Kim, Jung Hee Lee, Churl Woo Lee, Jae Hung Shin; J Korean Fract Soc 2005;18(2):165-169. Published online April 30, 2005; DOI: https://doi.org/10.12671/jkfs.2005.18.2.165

Abstract PDF

PURPOSE
To find out whether or not the computed tomographic (CT) classification systems of the calcaneal fracture are efficient in illuminating displaced posterior facet fragment and the degree of displacement can be evaluated by analyzing serial CT images.
MATERIALS AND METHODS
Seventy-seven hundred calcaneal fractures were classified by CT classification systems including Sanders classification, and the sagittal rotation angle of the posteior facet fragment was measured on the plain lateral radiograph. Among the serial axial CT images, a number of images with the cortical bone embedded in the cancellous portion were recorded and any significant relationship between each data were evaluated.
RESULTS
The conventional CT classification systems are rather insufficient in illuminating the extent of sagittal rotatory displacement. However, the number of CT images in which the cortical radiodensity was observed showed a significantly related with the degree of displacement.
CONCLUSION
The conventional CT classification of the calcaneal fractures is unsatisfactory in expressing the degree of sagittal rotatory displacement of the posterior facet fragment; this problem may be alleviated by observing the number of axial CT images in which cortical radiodensity was revealed within the calcaneal body.

The role of posterior malleolar fragments in ankle pain after trimalleolar fractures: Su Young Bae, Dong Hoon Sihn; J Korean Soc Fract 2003;16(1):59-66. Published online January 31, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.1.59

Abstract PDF

PURPOSE
There are some criticisms of indication for internal fixation of the posterior malleolar fragments in trimalleolar fractures. We tried to find out clinical and radiologic factors which affect on a clinical outcome of trimalleolar fractures.
MATERIALS AND METHODS
Thirty three patients who were treated for trimalleolar fractures and given anatomical reduction of lateral and medial malleolus were included. We divided patients into two groups, a group without the pain and the other group with the pain. Preoperative and postoperative lateral plain radiographic films were used to estimate fragment size, post-reduction gap and step off. By reviewing the medical records, other factors such as the time of ankle motion, weight loading and whether posterior malleolus was fixed. or not were stucdied. A clinical outcome was evaluated by AOFAS(American Orthopaedic Foot and Ankle Society) scaling system. We performed statistical analysis using Logistic regression analysis and Chi-square test on each factors.
RESULTS
There was no definite difference between two groups on the functional outcome. There was one case showing limited ankle motion. Seven patients were involved in the group with the pain and 23 in the group without the pain. The remnant fracture gap and step off of joint surface statistically showed the meaningful corellation with the pain but a fragment size and a surgical fixation, time of motion and weight loading did not show any significances.
CONCLUSION
We doubt the significance of the size of posterior malleolar fragment. We concluded that anatomical reduction of posterior malleolus is the most significant factor of a clinical outcome regardless of the size or internal fixation, especially the pain after trimalleolar injuries.

Ideal Placement of the Herbert/Whipple Screw in Scaphoid Fracture: A Model Study: Jae Doo Yoo, Jong Oh Kim, Yeo Hon Yun, Young Do Koh, Su Young Bae, Jeong Joon Lee; J Korean Soc Fract 2002;15(4):581-586. Published online October 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.4.581

Abstract PDF: PURPOSE
To evaluate optimal placement of the Herbert/Whipple screw in scaphoid fracture.
MATERIALS AND METHODS
Forty eight models molded from four cadaver scaphoids were used for this study. Using the Herbert/Whipple jig, the guide wire was placed distal to proximal into each scaphoid with twelve method which were four entry points and three target points. Guide wire placement was then evaluated with three planes in the proximal, middle, distal planes and distance from the nearest cortex.
RESULTS
The most concentric position in the proximal plane was D5, in the middle plane C10. As distal entry point, the most concentric position in proximal plane was C. There were no statistical concentric, as middle, distal plane, and proximal entry point, CONCLUSION: The most ideal placement were D5 in proximal fractures of the scaphoid, C5 in distal fractures. In waist fractures of the scaphoid, there were relatively safe, except A0 and D0. The position of entry points was more important than that of target points for ideal screw placement.

Radiologic Evaluation for the Safe Zone of Percutaneous Iliosacral Screw Fixation: Jong Keon Oh, Su Young Bae, Jong Oh Kim, Kwon Jae Roh, Jeong Joon Lee, Sang Yeol Chang; J Korean Soc Fract 2002;15(3):336-341. Published online July 31, 2002; DOI: https://doi.org/10.12671/jksf.2002.15.3.336

Abstract PDF

PURPOSE
To evaluate the correlation of the safe zone of percutaneous iliosacral screw fixation with sacral dysmorphism and sacral alar slope variation.
MATERIALS AND METHODS
We studied the plain radiographs and the pelvic bone CT images of 52 patients. We reviewed each cases in terms of Routt 's dysmorphism and sacral alar slope variation(anterior, coplanar and posterior to inter-ICD line). We divided each cases into narrow and wide groups by the width of safe zone for the transverse 6.5mm cannulated cancellous screw. The data were analysed by McNemar x2-test and Cochran Q-test(p<0.05).
RESULTS
Typical sacral dysmorphism was found in five cases(9%). Four cases with dysmorphism(80%) and eighteen non-dysmorphic cases(38.2%) revealed narrow safe zones. The sacral slopes were anterior in 16 cases, coplanar in 25 cases, and posterior in 11 cases. The safe zone was significantly narrow in the group with anterior slope variation.
CONCLUSION
We could not found definite correlation between sacral dysmorphism and a narrow safe zone because the incidence of dysmorphism was too low in our study which differed from Routt 's report. An anterior sacral alar slope on CT can be a significant risk indicator for potential narrow safe zone and the risk of screw malposition.

Radiation Exposure from Fluoroscopy during Orthopaedic Surgical Procedures: Su Young Bae, Jong Oh Kim, Jae Doo Yoo, Seong Yong Yoon, Jin Won Jang; J Korean Soc Fract 2001;14(4):792-798. Published online October 31, 2001; DOI: https://doi.org/10.12671/jksf.2001.14.4.792

Abstract PDF

PURPOSE
The aim of this study was to evaluate the radiation dose administered in orthopedic operative procedures and to determine whether all operation room personnel must use the lead protector.
MATERIALS AND METHODS
From March 2001 to May 2001, sixty six orthopedic operations were done with fluoroscopic intensifier(Series 9600TM, OEC Medical Systems Inc.). The accumulative exposure doses of operator, 1st assist, scrub nurse, circulating nurse and anesthesiologist were assessed by TLD(Thermo luminescence dosimeter) and compared with the dose limit set by the KINS(Korea Institute of Nuclear Safety). The exposure times and doses were evaluated in each cases and analyzed according to the each procedure. The exposure doses were assessed by the distance (Om, 0.5m, 1m, 2m) from the fluoroscopic generator.
RESULTS
Accumulative exposure doses(3 months) were checked 1.37mSv in operator, 1.73mSv in 1st assist, 0.17mSv in scrub nurse, 1.01mSv in circulating nurse, 0.01mSv in anesthesiologists and all doses were lower than dose limit set by the KINS(12.5mSv). Low exposure was checked in procedure of hand, ankle, cervical spine but high exposure was checked in IM nailing of femur(one way Anova with postHoc test, p<0.05). The exposure doses were decreased with the distance and exposure dose out of 1m was minimal.
CONCLUSION
Radiation is higher in IM nailing procedure but the total accumulative doses were safe especially in personnel who can fall apart from the operation field more than lm. So, we conclude that the lead protector is not essential to the all operation room personnel.
