Summary
This study details the precise biometry of the calcaneus, cuboid, and calcaneocuboid joint, revealing novel morphological types. Understanding these bone measurements aids in treating adult flatfoot and modeling joint function.
Area of Science:
- Orthopedics
- Anatomy
- Biomechanics
Background:
- Anatomical textbooks lack detailed biometric data for the calcaneus, cuboid bones, and calcaneocuboid joint.
- Accurate measurements are crucial for understanding foot biomechanics and surgical interventions.
Purpose of the Study:
- To provide precise biometric data for the calcaneus, cuboid bones, and calcaneocuboid joint.
- To identify and characterize novel morphological variations within these structures.
- To correlate bone morphology with joint function and surgical outcomes.
Main Methods:
- Biometric analysis of 50 calcanei and 30 cuboid dry bones.
- Examination of 21 anatomical specimens of the transverse tarsal joint.
- Measurements included length, width, angular orientation, contact surface, and radius of curvature.
Main Results:
- Identified several previously undocumented morphological types of the calcaneus and cuboid.
- Differentiated measurements between dry bones and anatomical specimens, considering ligamentous function.
- Established a basis for understanding calcaneocuboid joint morphology and its role in transverse tarsal joint locking.
Conclusions:
- The study provides essential biometric data for the calcaneus, cuboid, and calcaneocuboid joint.
- Findings offer insights into the etiology of adult flatfoot and potential osteotomy outcomes.
- Enhanced understanding of joint surfaces and biometry can lead to improved biomechanical modeling and clinical applications.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
01:10Bones of the Lower Limb: Tibia and Fibula
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...
01:16Bones of the Lower Limb: Femur and Patella
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the neck...
