Ultrasonography01:17

Ultrasonography

4.4K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Ultrasound I: Abdominal Ultrasonography

204
Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

Anatomical Positions01:11

Anatomical Positions

10.0K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Area of Science:

  • Medical imaging
  • Musculoskeletal ultrasound
  • Interventional procedures

Background:

  • Ultrasound is crucial for upper extremity diagnostics and interventions.
  • Current positioning may limit optimal access and efficiency.
  • Standardized positions are needed to improve procedural outcomes.

Purpose of the Study:

  • To introduce and evaluate the Total Supported Abduction (TSA) position.
  • To assess TSA's utility for ultrasound evaluations and guided interventions of the upper extremity.
  • To determine if TSA enhances clinical efficiency.

Main Methods:

  • The TSA position was utilized for ultrasound-guided procedures.
  • Evaluations included diagnostic assessments of median and ulnar nerves.
  • Interventions comprised injections for carpal tunnel syndrome, ulnar neuropathy, and tenosynovitis.

Main Results:

  • TSA provides optimal access to the medial arm, volar wrist, and palmar hand.
  • Facilitates both ipsilateral and bilateral evaluations/interventions with minimal patient repositioning.
  • Demonstrates potential for enhanced clinical efficiency, reducing time, materials, and space.

Conclusions:

  • The TSA position is effective for upper extremity ultrasound evaluations and interventions.
  • TSA improves access and simplifies procedures involving the median and ulnar nerves.
  • Incorporating TSA can lead to greater efficiency in clinical practice.
