Structural Joints: Fibrous Joints01:03

Structural Joints: Fibrous Joints

2.1K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Zero-Force Member

1.5K
A truss is a framework that comprises slender members connected at their ends by joints. Trusses are widely used in engineering and architecture to stabilize and strengthen structures like bridges, roofs, and towers. Truss members are designed to carry loads through tension and compression, enabling the truss to withstand external forces.
One critical concept in truss design is the idea of zero-force members. It refers to a truss member that experiences no stress under loading conditions.

Unsymmetric Loading of Thin-Walled Members01:23

Unsymmetric Loading of Thin-Walled Members

116
Thin-walled members with non-symmetrical cross-sections are vital to engineering structures, offering material efficiency and structural integrity. However, unsymmetrical loading on these members leads to complex stress distributions, resulting in simultaneous bending and twisting can cause deformation or structural failure. The interaction between bending and twisting requires detailed analysis to ensure structural resilience.
The concept of the shear center is crucial in countering the...

Structural Joints: Cartilaginous Joints01:17

Structural Joints: Cartilaginous Joints

2.3K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Torsion of Noncircular Members01:16

Torsion of Noncircular Members

143
Circular shafts undergoing torsional stress maintain their cross-sectional integrity due to their axisymmetric nature. This symmetry ensures an even distribution of stress, allowing the shaft to withstand torsion without distorting. In contrast, square bars, lacking this axial symmetry, experience significant distortion across their cross-sections when subjected to torsion, with the exception of along their diagonals and at lines connecting midpoints. A detailed examination of a cubic element...

Nurses' Legal Responsibilities III01:16

Nurses' Legal Responsibilities III

666
Nurse-to-nurse relationships are legally required to adhere to professional standards, ensuring a respectful and positive working environment. Professional conduct demands that nurses treat all colleagues respectfully and courteously, fostering a productive, supportive workplace. Nurses must actively eliminate bullying, discrimination, and harassment to maintain a safe and inclusive environment.
Cultivating a culture of collaboration and mutual respect among nurses transcends mere enhancement...

Summary

Non-union, a fracture that fails to heal, affects 3-5% of fractures and impacts quality of life. This review offers healthcare providers insights into non-union characteristics, causes, diagnostics, and varied treatments.

Area of Science:

  • Orthopedic Surgery
  • Traumatology
  • Bone Healing Biology

Context:

  • Non-union, a persistent fracture, occurs in 3-5% of bone breaks.
  • It significantly impairs physical function, mental well-being, and overall quality of life.
  • Etiology, presentation, and management of non-union are highly individualized.

Purpose:

  • To enhance healthcare providers' understanding of non-union cases.
  • To detail the diverse characteristics, causes, diagnostic methods, and treatment strategies for non-union.
  • To provide clinical insights through the presentation of three distinct non-union cases.

Summary:

  • This work examines non-union, a fracture complication hindering bone repair.
  • It covers the condition's prevalence, negative health impacts, and variable clinical aspects.
