MORPHOMETRY OF TALAR ARTICULAR FACET OF THE BODY OF
NAVICULAR BONE .
DR. V.JANAKI et al
INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH

Background:In the formation of talo calaneo navicular joint ,congruence of articular surfaces of talus, navicular and calcaneum is very important
to maintain the stability and in the distribution of body weight to the remaining tarsal bones.
Aim: To prepare morphometric data of talar surfaces (posterior surface) of body of navicular bone, to nd if there is any difference between both the
sides (right and left) of measurements , range of measurements and it's mean value of measurements in telangana region people.
Material and Methods: The study was conducted on 47 (right 21 left 26) dry Human adult navicular bones of undetermined gender and age
separated into right side and left side bones. Each right and left Human navicular bone were assigned a serial number. On the talarsurface (posterior
surface) surface, vertical length (height) of talar surface and transverse length (breadth) of talar surface of navicular bones were measured. The
Data was tabulated and Analysed.
Results: On the Posterior Articular surface (talarsurface), the range of vertical length (height) of navicular bone were 16mm to 27mm on Right
side and 16mmto28 mm on Left side.The range of transverse length (breadth) of navicular bone were 23mm to 30mm on Right side and 24mm to
32mm on Left side.
The mean values of vertical length (height) and transverse length (breadth) of talar surface of navicular bone were 19.7mm and 25.6 mm on Right
side respectively.
The mean values of vertical length (height) and transverse length (breadth) of talar surface of navicular bone were 20.0mm and27.3mm on Left
side.
Conclusion:The talar articular surface measurements of opposite navicular bone can be used as a control during navicular bone replacement
surgery, it may help surgeons to plan pre-operatively to design accurate navicular bone prosthesis and implants.

Human navicular bone: a morphometric and morphological evaluation
Nandini Rajaram et al
Surg Radiol Anat. 2023 Nov 15

Background: The composition of navicular joint complex is crucial to perform surgical interventions for multiple pathological foot aetiologies. The data on human navicular bone and its facets from Indian population remain scarce in literature.

Aims and objectives: To evaluate the morphometry and morphology of navicular bone.

Methodology: A total of 77 (right: 40; left: 37) dried human navicular bones were used. The collected data were entered and analysed in SPSS software.

Results: The anteroposterior diameter of navicular bone on right side was 15.19 mm (13.92, 16.77) and on left side was 15.87 mm (13.83, 17.27). The transverse diameter on right and left sides were 34.21 mm (31.74, 36.6) and 33.59 mm (30.23, 35.43), respectively. The vertical diameter measured on the right was 22.31 mm (21.19, 23.94) and on left 22.53 mm (20.8, 24.24). Morphometric evaluation showed no significant difference between right and left navicular bones. The commonest shape for posterior facet was quadrilateral, on the right (62.5%) and left (40.5%). The most common shape of anterior facet for medial cuneiform is quadrilateral, on the right (85%) and left (89.1%). For intermediate cuneiform, triangular facet was common on the right side (72.5%) and on the left (59.5%). The lateral cuneiform facet was bean shaped on right side (72.5%) and quadrilateral on the left side (32.5%). There was a significant difference in shape distribution between right and left (P < 0.05). The median length of the groove for tibialis posterior tendon was 18.01 mm and 16.19 mm on right and left side, respectively. Cuboid facet was observed in 28 (70%) and 26 (65.9%) navicular bones on right and left sides, respectively.

Conclusion: There is no significant difference between right and left bones with regards to morphometric parameters. Morphological evaluation revealed significant difference in the distribution of shape between right and left bones.
