Human navicular bone: a morphometric and morphological evaluation
Nandini Rajaram, S. Srinivasan & Suman Verma
15 November 2023

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

Morphological and morphometric analysis of tarsal bones according to sex
Nihal Gurlek Celik, Burcu Akman
Surg Radiol Anat. 2024 Aug 2

Purpose: Our aim in the study is to measure the area and volume of the tarsal bones and examine the typing of the talus and calcaneus joint surfaces according to sex.

Methods: In our study, the area and volume measurements of 630 tarsal bones and the morphology of the talus/calcaneus were analyzed by transferring thin-section Computed Tomography (CT) images to the 3D Slicer program.

Results: The volume and area sizes of the foot bones are calcaneus, talus, cuboid, navicular, medial cuneiform, lateral cuneiform, and intermediate cuneiform, respectively. All area and volume values of males were statistically higher than females (p < 0.05). The right side calcaneus area, intermediate cuneiform area, and lateral cuneiform area values were statistically higher than the left side (p < 0.045, p < 0.044, p < 0.030, respectively). There was no statistical relationship between age and area/volume values (p > 0.05). Three different types were seen in the calcaneus and seven in the talus. The most common type in the calcaneus was B1 (40%), and the least common type was A (27.8%). Regardless of the subgroups, the most common type in the talus was type B (37.8%), while the least common type was E2 (1.1%).

Conclusion: Although morphometric measurements of tarsal bones differed according to sex, they did not differ according to age. The frequency of occurrence of the types of articular surfaces of the talus and calcaneus varies according to populations. We think that the morphometry and morphology of tarsal bones will contribute to invasive procedures regarding tarsal bones and surrounding structures, and that three-dimensional bone modeling can be used to create educational materials.

Morphological measurements and classification of the navicular bone: a study based on computed tomography imaging
Liang Ao, Huining Tang, Wangyu Wu, Songtao Jiang, Wenjing Luo & Lei Zhang
Surgical and Radiologic Anatomy

Objective
The purpose of this study was to present the classification of navicular bones and the anatomical basis for the diagnosis and treatment of navicular fractures of the foot.

Method
351 computed tomographic (CT) images of the navicular bone were analyzed and classified. The navicular bone’s anatomical morphology was measured by three independent researchers in each type. Analysis and recording of the measurement results followed.

Result
Navicular bones were assorted into three types: I shape(37.04%), II shape(54.41%), and III shape(8.55%). The left and right sides did not differ in any appreciable ways, except ab, bc, and ∠abc (P < 0.05); And all data were statistically different between men and women except for ∠abc (p > 0.05).

Conclusion
The classification of the navicular bone in this study may be helpful in making the treatment decision for navicular fracture.

Evaluation of the relationship of navicular tuberosity and tibialis posterior tendon with medial longitudinal arch
Turan Koç et al
Ann Anat. 2025 Apr 15:260:152663
Background: Although it is suggested that the morphometry of the medial protrusion of tuberosity of navicular bone (TNm) and tibialis posterior (TP) tendons is related to this pathology, there is insufficient evidence. This study aimed to reveal the relations of the medial longitudinal arch (MLA) with the tendons of the TP and the TNm.

Materials and methods: Dissections of this study were performed on the dorsal and plantar aspects of 34 formalin-fixed cadavers and amputated feet (15 female, 19 male). All attachment sites and connections of the main TP (TPmt) and slips are evaluated and classified. Morphometric measurements of TNm and all tendon slips were performed. Feet were assessed for pes planus (PP) presence using the navicular index and the first metatarsal-calcaneus angle and grouped as normal and pathological (pes planus). For all parameters, differences between groups, genders, and sides were evaluated.

Results: The TP attached to the calcaneus, navicular, medial and lateral cuneiform, cuboid and fourth metatarsal bone (MT4) in all feet. Additionally, slips were attached to the other tarsal and metatarsal bones (MT) with different combinations. The bony prominence exceeded the determined surgical reference line medially (6.73 ± 2.96 mm) in all feet. The width and length of the medially protruding part of TN revealed that it did not cause any disruption on the morphometry (cross-sectional areas) of TPmt and its slips. No significant difference was found between the normal and pathological groups according to the classification criteria regarding tendon types, number of muscle attachments, slips and morphometry of the TNm. However, it was determined that the cross-sectional area and thickness of the tendon connecting to the MT4 and thickness of the tendon connecting to the MT5 were greater in the pes planus group (PP).

Conclusion: There was no evidence that TNm morphometry affects tendon distribution or facilitates PP in the arch of the foot. Our data indicates that the tendon extension dimensions of the muscle attached to MT4 and MT5 change depending on PP.
