Mitral Stenosis I: Introduction01:22

Mitral Stenosis I: Introduction

Mitral Valve Stenosis (MVS) is a heart condition where the mitral valve narrows, impeding blood circulation from the left atrium to the left ventricle. The etiology and pathophysiology of this condition are multifaceted, leading to a cascade of cardiovascular complications.Causes of Mitral Valve StenosisRheumatic Heart Disease: It is the main cause of mitral valve stenosis, particularly in developing nations. This condition arises from rheumatic fever, an inflammatory illness resulting from...
Structural Joints: Synovial Joints01:16

Structural Joints: Synovial Joints

Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
Ankle Joint01:10

Ankle 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...
Pericarditis I: Introduction01:22

Pericarditis I: Introduction

Pericarditis is defined as the inflammation of the pericardium, the thin, sac-like membrane surrounding the heart. This condition can cause significant chest pain and other symptoms, often necessitating medical intervention. The pericardium has two layers: the inner visceral layer and the outer parietal layer, separated by a small amount of fluid that reduces friction during heartbeats.Types of PericarditisPericarditis can be classified into several types based on the duration and nature of the...
Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
Pericarditis III: Medical Management01:17

Pericarditis III: Medical Management

The primary objectives of managing pericarditis are to determine the underlying cause, provide effective therapy for treatment and symptom relief, and promptly detect signs and symptoms of cardiac tamponade. The following outlines the essential aspects of medical management for pericarditis:ObjectivesDetermine the Cause: Identifying the underlying cause of pericarditis is crucial for targeted treatment. Causes include viral infections, autoimmune diseases, post-cardiac injury syndrome, and...

Area of Science:

  • Orthopedics
  • Radiology
  • Rheumatology

Background:

  • Tenosynovitis involves inflammation of the tendon's synovial sheath.
  • Stenosing tenosynovitis results from anatomical, mechanical, and hormonal factors.
  • Common forms include de Quervain tendinopathy and trigger finger.

Purpose of the Study:

  • To describe the ultrasonographic findings in stenosing tenosynovitis.
  • To highlight the role of thickened retinacula in tendon constriction.

Main Methods:

  • Review of clinical presentations of stenosing tenosynovitis.
  • Ultrasonographic examination of affected tendons and surrounding structures.

Main Results:

  • Ultrasonography characteristically shows a thickened retinaculum or pulley.
  • This thickening constricts the osseofibrous tunnel, impeding tendon gliding.
  • Specific forms identified include de Quervain, trigger finger, and others affecting wrist, foot, and ankle tendons.

Conclusions:

  • Ultrasonography is crucial for diagnosing stenosing tenosynovitis.
  • Identifying thickened retinacula is key to understanding the mechanism of tendon constriction.
  • This condition encompasses various specific tendinopathies affecting different anatomical locations.
