Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

13.4K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Space Trusses: Problem Solving

666
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. Due to its adaptability and capacity to withstand complex loads, the space truss is widely used in various construction projects.
Consider a tripod consisting of a tetrahedral space truss with a ball-and-socket joint at C. Suppose the height and lengths of the horizontal and vertical...

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...

Eccentric Axial Loading in a Plane of Symmetry01:16

Eccentric Axial Loading in a Plane of Symmetry

335
Eccentric axial loading occurs when an axial load is applied away from the centroidal axis of a structural member. This scenario is common in engineering, where structural elements may not be directly aligned due to various design or functional requirements.

Area of Science:

  • Orthopedics
  • Neurology
  • Vascular Surgery

Background:

  • The quadrilateral space is a critical anatomical region in the shoulder.
  • It transmits the axillary nerve and posterior circumflex humeral artery (PCHA).
  • Impingement in this space causes Quadrilateral Space Syndrome (QSS).

Purpose of the Study:

  • To review the clinical presentation, diagnosis, and management of Quadrilateral Space Syndrome (QSS).
  • To highlight QSS as a differential diagnosis in patients with shoulder and arm symptoms.

Main Methods:

  • Review of clinical presentations and diagnostic findings.
  • Discussion of conservative and surgical treatment options.
  • Emphasis on imaging (MRI, angiography) and emergent therapies.

Main Results:

  • QSS symptoms include paresthesias, motor loss, pain, and vascular complications.
  • Athletes with repetitive overhead movements are at higher risk.
  • MRI may show muscle atrophy; angiography can reveal PCHA abnormalities.

Conclusions:

  • Early diagnosis of QSS is crucial, especially in at-risk populations.
  • Conservative treatment (physiotherapy) is the first line.
  • Surgical decompression and vascular interventions are effective for severe cases.
