Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...
Fibril-associated Collagen01:11

Fibril-associated Collagen

Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...
Flail Chest-I01:24

Flail Chest-I

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
Traumatic Brain Injury l: Introduction01:28

Traumatic Brain Injury l: Introduction

DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...

Summary
This summary is machine-generated.

This study details numerous patterns of traumatic triangular fibrocartilage complex (TFCC) tears, including atypical types. A new classification system for TFCC injuries may be needed due to findings beyond current categorization.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Anatomy

Background:

  • The triangular fibrocartilage complex (TFCC) is crucial for wrist stability.
  • Palmer's classification is the standard for TFCC tears but may not encompass all traumatic patterns.

Purpose of the Study:

  • To document and categorize diverse patterns of traumatic TFCC tears.
  • To assess the adequacy of Palmer's classification for all observed traumatic TFCC tears.
  • To propose the need for an updated TFCC tear classification system.

Main Methods:

  • Arthroscopic and macroscopic examination of 173 traumatic TFCC tears in wrists.
  • Classification of tears into disk tears (slit, flap, horizontal, intra-articular) and peripheral tears (ulnocarpal ligament, dorsal, radial, styloid, foveal, DRUJ ligament).

Main Results:

  • Identified multiple distinct patterns of traumatic TFCC tears.
  • Observed tear combinations in 32 wrists.
  • Found several atypical tear patterns not covered by Palmer's classification.

Conclusions:

  • Current Palmer classification is insufficient for all traumatic TFCC tears.
  • A new, comprehensive classification system for traumatic TFCC tears is warranted.
  • Detailed documentation of tear patterns aids in understanding TFCC injuries.
