Ankle Joint01:10

Ankle Joint

3.0K
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...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Positron Emission Tomography

7.2K
Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Positron Emission Tomography (PET) is a medical imaging technique that provides crucial insights into the body's physiological functions at a molecular level. It is an indispensable resource for diagnosing, staging, and monitoring various illnesses, notably cancer, neurological disorders, and cardiovascular conditions.

Electron Microscope Tomography and Single-particle Reconstruction01:07

Electron Microscope Tomography and Single-particle Reconstruction

2.9K
Transmission electron microscopy (TEM) can be used to determine the 3D structure of biological samples with the help of techniques such as electron microscope tomography and single-particle reconstruction. While single-particle reconstruction can examine macromolecules and macromolecular complexes in vitro conditions only, tomography permits the study of cell components or small cells in vivo.
Electron Tomography
Electron tomography can be performed either in TEM or STEM (scanning transmission...

Area of Science:

  • Orthopedic surgery
  • Biomechanics
  • Anatomy

Background:

  • Accurate ankle joint morphometry is vital for effective treatment of ankle disorders.
  • Current data on ankle joint axis orientation and morphology is insufficient.
  • Understanding these features is key to optimizing conservative and operative therapies.

Purpose of the Study:

  • To evaluate the three-dimensional morphometry of Caucasian ankle joints.
  • To gather detailed information on the ankle joint axis and morphology.

  • Determined key dimensions of the trochlea tali and tibial articular surfaces.
  • Specific measurements include radii, arc lengths, and widths of the talar dome and tibial plateau.
  • Detailed quantitative data on ankle joint geometry was obtained.

Conclusions:

  • The study provides a comprehensive 3D morphometric analysis of Caucasian ankle joints.
  • This detailed dimensional data is essential for informed development and placement of orthopedic implants.
