Fractures: Bone Repair01:27

Fractures: Bone Repair

4.3K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

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...

Simple Trusses

2.4K
A truss is a structural framework consisting of slender members connected at joints, designed to support external loads while minimizing material usage and weight. Simple trusses are a type of planar truss where all members lie within a single two-dimensional plane.
The most basic planar truss is a simple truss with three members arranged in a triangular formation. This triangular truss is inherently stable and rigid due to its geometry, making it an ideal starting point for creating more...

Flail Chest-II

Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Functional Classification of Joints01:09

Functional Classification of Joints

6.0K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Space Trusses01:25

Space Trusses

1.1K
A space truss is a three-dimensional counterpart of a planar truss. These structures consist of members connected at their ends, often utilizing ball-and-socket joints to create a stable and versatile framework. The space truss is widely used in various construction projects due to its adaptability and capacity to withstand complex loads.
At the core of a space truss lies the fundamental unit known as the tetrahedron. This structure is composed of six members that form a three-dimensional shape...

Summary
This summary is machine-generated.

Triquetral fractures, the second most common carpal bone injuries, often result from falls. Most cases are treated non-surgically with immobilization, leading to good outcomes, but careful evaluation is crucial for potential complications.

Area of Science:

  • Orthopedic Surgery
  • Hand and Wrist Injuries
  • Traumatology

Background:

  • Triquetral fractures represent 15-18% of carpal bone fractures, making them the second most common.
  • These injuries typically occur from direct impact on the ulnar wrist or ligament avulsion.

Purpose of the Study:

  • To review current knowledge on triquetral fractures.
  • To cover anatomy, pathophysiology, diagnosis, treatment, outcomes, and complications.

Main Methods:

  • Literature review of triquetral fractures.
  • Synthesis of information on evaluation, diagnosis, and management.

Main Results:

  • Three main fracture types exist: dorsal cortical (most common, benign), body, and volar cortical (least common, potentially problematic).
  • Nonsurgical management with immobilization is effective for most fractures, yielding good outcomes.
  • Surgical intervention is reserved for displaced or unstable fractures.
  • Potential complications include non-union, triangular fibrocartilage complex injury, and pisotriquetral arthritis.

Conclusions:

  • Triquetral fractures require consideration in ulnar-sided wrist pain differentials.
  • While often managed non-surgically, thorough evaluation is necessary to prevent long-term issues like instability and arthrosis.
  • Further research is needed to optimize surgical treatment strategies.
