Radiological Assessment for Distal Fibular Length: Il Hoon Sung, Jong Min Lee; J Korean Soc Fract 2003;16(2):208-214. Published online April 30, 2003; DOI: https://doi.org/10.12671/jksf.2003.16.2.208

Abstract PDF: PURPOSE
This study was performed to reevaluate the radiological parameters for assessing the length of the distal fibula in the mortise view of the ankle and to introduce a more reliable method to lessen measurement error.
MATERIALS AND METHODS
Mortise view radiographs of 36 normal ankles from 18 healthy volunteers were obtained. The talocrural angle and bimalleolar angle were measured two times and compared bilaterally by two independent observers. Also, The lateral malleolar angle, newly devised in our department was measured and compared bilaterally.
RESULTS
The average of the talocrural angle, bimalleolar angle, and lateral malleolar angle was 78.4 degrees (range 74 to 83), 78.3 degrees (range 73 to 86), and 36.7 degrees (range 30 to 41), respectively. The difference of the talocrural angle, bimalleolar angle, and lateral malleolar angle between right and left was 2.1 degrees, 3.0 degrees, and 1.2 degrees (95% confidence limit), respectively. Intraobsever difference of the talocrural angle, bimalleolar angle, and lateral malleolar angle was 1.5 degrees, 1.6 degrees, and 0.4 degrees, respectively. Interobsever difference of the talocrural angle, bimalleolar angle, and lateral malleolar angle was 1.3 degrees, 2.4 degrees, and 1.0 degrees, respectively.
CONCLUSION
When using various measurement methods to judge the length of the distal fibula, the measurement error should be considered. The proposed method, lateral malleolar angle, would be a good method for assessing the length of distal fibula in the mortise view of ankle.

Radiologic Evaluation of the Ankle Joint: Comparison of Different criteria & its A vailability of Clinical Practice: Deuk Soo Hwang, Seung Ho Yune, Kwang Jin Rhee, June Kyu Lee, Je Taek Jeong; J Korean Soc Fract 1998;11(4):880-885.

Abstract PDF: Generally it is Known that the best clinical results in treatment of injuries of the ankle are obtained by anatomical restoration of the joint. For objective measurements of tibiotalar joint, some investigators ued different criteria and defined the specific reference points under variable angle of internally rotated anteroposterior projection. But, occasionally we didn't acquire the accurate roentgenographic finding that was suggested by investigators. So, we check the variable angle of internal rotation film in addition to angle suggested by investigators and compare the criteria between them. The purpose of this study is to evaluate availability of internally rotated mortise view and its criteria in clinical practice. Following results was acquired. First, there was no significant difference in measuring the medical clear space on depand on variability of rotation angle. Second, the overlapping distance of tibiofibular syndesmosis decreased by increasing internal rotation angle, but was not under 1mm (ie, index of injury). A third, to measure the Weber's 3 criteria, we need to check the variable internal rotation angle, if necessary. Finally, we acquired the normal range of measurement about Tile's 2 criteria by variable internal rotation angle.
