Summary
This case report details a rare twisting elbow dislocation without fracture, successfully treated with closed reduction and early mobilization. The patient achieved a full range of motion, highlighting effective management of elbow injuries.
Area of Science:
- Orthopedic Surgery
- Traumatology
Background:
- Elbow dislocations are common, second only to shoulder dislocations, with an incidence of 6-8 per 100,000 annually in the US.
- Classified by displacement direction (anterior, posterior, lateral, divergent), posterior dislocations are most frequent.
- Associated fractures are common, but this report focuses on a rare case without bony injury.
Observation:
- A 55-year-old woman presented with acute right elbow pain, swelling, and forearm pronation after a fall.
- Clinical examination revealed no neurovascular deficits.
- Imaging confirmed a dislocation without associated fractures.
Findings:
- Closed reduction under local anesthesia successfully restored elbow joint alignment.
- Post-reduction, there were no neurovascular complications.
- One-year follow-up showed no ectopic calcification and a stable joint with a full range of motion.
Implications:
- This case underscores that elbow dislocations can occur without fractures, necessitating prompt diagnosis and management.
- Early active mobilization, avoiding forceful passive motion, is crucial for optimal recovery and preventing complications like myositis ossificans.
- Effective management leads to stable joints and full functional recovery in elbow dislocation patients.

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
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
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.

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 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...

Spinal 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.
