Summary
This case report details an anatomical variant of the radial artery. The radial artery was observed to run superficially to specific wrist tendons, impacting surgical considerations.
Area of Science:
- Anatomy
- Surgical Anatomy
Background:
- The radial artery, a terminal branch of the brachial artery, typically originates at the radial neck and descends along the forearm's lateral side.
- It courses around the wrist, passing beneath specific tendons before crossing the anatomical snuffbox floor.
Observation:
- This case report documents an anatomical variation involving the radial artery.
- The radial artery was observed to run superficially over the radial fossa, superficial to the tendons of abductor pollicis, extensor pollicis longus, and extensor pollicis brevis muscles.
Findings:
- An atypical topographical relationship of the radial artery with adjacent wrist structures was identified.
- This variant presents a deviation from the typical anatomical course of the radial artery in the wrist region.
Implications:
- Understanding this radial artery variation is crucial for accurate surgical planning and execution.
- Awareness of such anatomical anomalies can prevent iatrogenic injuries during hand and wrist surgeries.

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

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:

Apical-Radial (A-R) Pulse Assessment
The A-R pulse assessment involves simultaneous evaluation of the apical and radial pulses. When the apical and radial pulse rates vary, this assessment helps identify a pulse deficit.

01:09Bones of the Upper Limb: Radius
3.1K
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.

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...
