Summary
Fabricating prosthetic fingers in the clinical rest position (CRP) offers better aesthetics and function compared to the extended position (PFE). This approach provides a promising alternative for improved prosthetic finger outcomes.
Area of Science:
- Prosthodontics
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Effective prosthetic fingers require precise planning and fabrication for aesthetics and passive function.
- Prosthetic outcomes depend on retention and mimicking natural finger contours.
- Current literature predominantly focuses on fabrication in the palms and fingers extended (PFE) position.
Purpose of the Study:
- To compare prosthetic finger fabrication techniques in clinical rest position (CRP) versus PFE.
- To evaluate aesthetics and passive function of prostheses fabricated in CRP and PFE.
- To determine the superior approach for prosthetic finger design and outcomes.
Main Methods:
- Systematic review of 20 articles from national and international journals over 20 years.
- Analysis of fabrication techniques for prosthetic fingers in CRP and PFE.
- Examination of aesthetic and passive functional outcomes for both fabrication positions.
Main Results:
- Most existing literature addresses PFE fabrication, with limited focus on CRP.
- Prosthetic fingers fabricated in CRP demonstrate superior aesthetic appearance.
- CRP fabrication also yields improved passive functional outcomes compared to PFE.
Conclusions:
- Prosthetic finger fabrication in CRP is a promising alternative to PFE.
- CRP offers enhanced aesthetic and partial functional benefits.
- Further research is needed to validate these findings and advance prosthetic development.

Assessment of Radial Pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:

01:10Pre-Procedural Guidelines for Assessing Blood Pressure
Accurate blood pressure assessment is crucial for diagnosing and managing various health conditions. To ensure the reliability of these measurements, healthcare professionals must adhere to standardized pre-procedural guidelines. These guidelines enhance patient safety and improve the overall quality of healthcare. The following steps are essential for obtaining accurate and consistent blood pressure readings, from using the appropriate tools to ensuring effective communication with the patient.
01:16Muscles of the Forearm that Move the Hand and Fingers
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi radialis,...

01:24Physical Assessment of the Respiratory Tract II: Palpation
Physical assessment of the respiratory tract is critical in identifying potential health issues. One key component of this assessment is palpation, a technique healthcare providers use to assess the body for abnormalities. This content explores the method of palpation in evaluating the respiratory tract, focusing on thoracic palpation and tactile fremitus.

01:23Assessment of the Abdomen III: Palpation
Palpation is a crucial tactile examination method for assessing abdominal organs and detecting conditions like tenderness, distention, masses, or fluid. It involves both light and deep palpation techniques, each serving specific diagnostic purposes. Light palpation helps identify tenderness and other surface-level indicators, while deep palpation locates and assess abdominal masses and organ boundaries. A skilled professional can gather valuable insights through palpation, including evaluating...

Palpation involves feeling the body to evaluate texture, size, consistency, and tenderness for assessing cardiovascular health. The following steps are organized in a head-to-toe order:
Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...
