Summary
A bony ridge in the wrist
Area of Science:
- Orthopedic surgery
- Anatomy
- Radiology
Background:
- De Quervain tenosynovitis, a common wrist condition affecting the first extensor compartment, disproportionately impacts females.
- Previous research has not adequately explored the role of osseous anatomy in this prevalence difference.
Purpose of the Study:
- To investigate potential anatomical differences in the distal radius between sexes.
- To determine if osseous variations in the first extensor compartment correlate with the higher incidence of De Quervain tenosynovitis in females.
Main Methods:
- Computed tomography (CT) imaging was utilized to evaluate 244 wrists (72 female, 172 male).
- The presence or absence of a bony ridge on the floor of the first extensor compartment was assessed using multiplanar reconstructions.
Main Results:
- A bony ridge was identified in 23.8% of all wrists studied.
- Females exhibited a higher prevalence of this bony ridge (33.3%) compared to males (19.8%).
- The presence of a bony ridge within a groove of the first extensor compartment was statistically linked to the female sex.
Conclusions:
- Two distinct tendon groove morphologies were observed in the first extensor compartment.
- A bony ridge is significantly more common in females, suggesting a potential anatomical predisposition.
- Further investigation is warranted to elucidate the precise relationship between this bony ridge morphology and the increased prevalence of De Quervain tenosynovitis in females.

01:09Bones of the Upper Limb: Radius
10.8K
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.

01:16Muscles of the Forearm that Move the Hand and Fingers
2.9K
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...

01:16Muscles that Move the Forearm
4.4K
The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...

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:

01:15Bones of the Upper Limb: Ulna
10.5K
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...

01:22Spinal Nerves: Plexus I

Nerve plexuses are networks of interlacing nerves that serve as communication hubs to distribute and organize nerve action across various body regions. The nerve plexuses are organized into the cervical plexus located in the neck region, brachial plexus in the shoulder area, lumbar plexus found in the lower back, sacral plexus situated in the pelvis, and coccygeal plexus located in the coccygeal region.
