Bones of the Upper Limb: Humerus

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Bones of the Upper Limb: Ulna

Bones 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...

Bones of the Upper Limb: Radius

Bones 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.
The radius has a nail-shaped head, and a short...

Muscles that Move the Forearm

Muscles that Move the Forearm

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...

Arteries of the Upper Limbs

Arteries of the Upper Limbs

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...

Muscles of the Forearm that Move the Hand and Fingers

Muscles 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,...

Summary

This case report details a rare bipolar forearm dislocation involving elbow and wrist injuries. Prompt surgical intervention led to satisfactory functional recovery of the elbow and wrist.

Area of Science:

Orthopedic Surgery
Trauma Management
Case Report

Background:

Bipolar forearm dislocation is a rare and complex injury pattern.
This specific combination of elbow and wrist injuries presents significant management challenges.

Observation:

A 23-year-old patient sustained a divergent elbow dislocation, radial head fracture, ulna fracture, perilunate dislocation, and scaphoid fracture after a fall.
The injury was characterized as a bipolar dislocation of the forearm.

Findings:

Emergency management included closed reduction of the elbow, ulna osteosynthesis, scaphoid internal fixation, and wrist K-wiring.
At 26 months post-injury, the patient demonstrated satisfactory elbow function and a wrist range of motion from 50° flexion to 40° extension.
Radiographic evidence showed satisfactory scaphoid healing.

Implications:

This case highlights the successful management of a rare, complex bipolar forearm dislocation.
The findings underscore the importance of prompt and comprehensive surgical intervention for achieving favorable functional outcomes in severe upper extremity trauma.
Such rare injury patterns warrant further investigation and reporting to enhance understanding and treatment strategies in orthopedic trauma.
