Summary
The triangulation method offers superior reproducibility and reliability for assessing wrist alignment compared to traditional angles. This makes it a more dependable tool for orthopedic measurements.
Area of Science:
- Orthopedics
- Radiology
- Biomechanics
Background:
- Static carpal alignment is crucial for wrist function.
- Existing radiologic methods like scapholunate, radiolunate, and capitolunate angles have limitations.
- A need exists for more reliable and reproducible measurement techniques.
Purpose of the Study:
- To evaluate the intraobserver reproducibility and interobserver reliability of the triangulation method.
- To compare the triangulation method with established angles (scapholunate, radiolunate, capitolunate) for static carpal alignment.
Main Methods:
- Twenty orthopedic residents and staff performed four radiologic measurements on digitized wrist radiographs.
- Measurements included scapholunate, radiolunate, capitolunate angles, and the triangulation method.
- Measurements were repeated after 30 days to assess reproducibility and reliability.
Main Results:
- The triangulation method demonstrated the highest intra- and interobserver agreement.
- This agreement was significantly better than for capitolunate and radiolunate angles.
- The scapholunate angle showed the next best reproducibility and reliability.
Conclusions:
- The triangulation method is a more reproducible and reliable technique for assessing static midcarpal alignment.
- It offers superior observer agreement compared to scapholunate, radiolunate, and capitolunate angles.
- Further validation is needed as no radiographic gold standard currently exists.

01:09Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.

01:27Assessment of the Cardiovascular System III: Palpation
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...

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,...

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:

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:15Bones of the Upper Limb: Ulna
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side of the...
