Ankle Joint01:10

Ankle Joint

3.8K
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...

DefinitionRenal angiography, also known as renal arteriography, is an imaging technique used to obtain a comprehensive view of blood flow and the vascular structure of blood vessels in the kidneys and surrounding areas.PurposeRenal angiography detects blood vessel abnormalities in the kidneys, such as aneurysms, stenosis, thrombosis, vascular tumors, and renal artery stenosis. It evaluates kidney function and guides interventional treatments like angioplasty or stent placement.Pre-Procedure...

Introduction: MRI and CT scans are crucial advancements in medical imaging techniques, playing a vital role in diagnosing conditions related to the gastrointestinal (GI) system. Each scan serves distinct purposes, targets specific areas, and requires unique nursing duties.
Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • First-generation total ankle replacement devices had disappointing outcomes.
  • Total ankle arthroplasty is increasingly preferred over ankle arthrodesis for end-stage ankle osteoarthrosis.
  • Advancements have significantly improved total ankle replacement surgery.

Purpose of the Study:

  • To review innovations in total ankle replacement surgery.
  • To highlight the importance of preoperative evaluation and imaging in total ankle arthroplasty.
  • To discuss the role of imaging in detecting complications.

Main Methods:

  • Review of recent advancements in total ankle replacement.
  • Discussion of clinical and radiographic evaluation techniques.
  • Emphasis on the use of computed tomography for complication assessment.

Main Results:

  • Total ankle arthroplasty is now a common procedure for end-stage ankle osteoarthrosis.
  • Preoperative planning involving imaging is crucial for optimal surgical outcomes.
  • Early identification of hardware loosening or subsidence through imaging allows for timely intervention.

Conclusions:

  • Modern total ankle replacement surgery offers improved results compared to earlier generations.
  • Thorough preoperative assessment and vigilant postoperative monitoring with imaging are essential for successful total ankle arthroplasty.
  • Computed tomography plays a valuable role in evaluating periprosthetic issues like lucency and osteolysis.
