Morphometry of Articular Facets of The Body of Talus
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 5
Abstract
Background: In the formation of Ankle joint, tibio-fibular mortice receives superior, medial and lateral articular surfaces of body of Talus. Because of very limited availability of the data on the Morphometry of the articular facets on the Body of the dry human Tali, this study was undertaken. Aims: To prepare morphometric data of the articular facets on the superior, medial and lateral surfaces of body of Talus, to find if there is any difference between both the sides of measurements and to compare the results with the previous studies. Methods and Material: 42 Dry Human Tali (20 Right and 22 Left) were measured with Digital vernier caliper for the following Measurements: 1.On the Trochlear surface: Medial length, Central length, Lateral length, Anterior width, Central width, Posterior width. 2.On the lateral triangular articular facet: Central height, Central width. 3. On the coma shaped medial articular facet: Central height, Central width. Results: Superior Articular Surface:On the superior Articular surface, the mean values of Medial, Central and Lateral length were 28.4,29.4 and 28.4mm on Right side and 31.0, 28.0 and 30.0mm on Left side. Mean Anterior, Central and Posterior widths were 28.5, 26.4 and 21.3mm on right side and 26.1, 24.4 and 22.7mm on left side.Medial Articular Surface: Mean central height on the medial articular surface was 12.4mm on the right side and 10.2mm on the left side, Mean central width on the medial articular surface was 24.0mm on the right side and 18.2mm on the left side. Lateral Articular Surface:Mean central height on the lateral articular surface was 22.14mm on the right side and 26.0mm on the left side. Mean central width on the lateral articular surface was 20.8mm on the right side and 16.3mm on the left side. Conclusion:The trochlear articular surface is wider in front, measurements of opposite talus bone can be used as a control during talus bone replacement surgery, it may help surgeons to plan pre-operatively to design accurate talus bone prosthesis and talus implants.
