Summary
Elbow injuries are common in emergency departments. A normal range of motion and full extension can help identify patients who do not need elbow x-rays, reducing unnecessary radiation exposure.
Area of Science:
- Orthopedic Surgery
- Emergency Medicine
- Radiology
Background:
- Elbow injuries constitute 2-3% of emergency department visits.
- High rates of radiography and missed fractures are associated with elbow injuries.
- This study investigates clinical examination components correlating with normal elbow radiographs.
Purpose of the Study:
- To identify clinical examination findings that best predict normal elbow radiographs.
- To develop a clinical rule for managing elbow injuries and reduce unnecessary imaging.
Main Methods:
- Prospective study in a district general hospital's emergency department.
- Inclusion of patients with elbow injuries, excluding those unable to cooperate.
- Data collection via proforma on clinical examination features and radiograph results.
Main Results:
- Full elbow extension showed high specificity (0.916) for normal radiographs.
- Equal range of motion (ROM) demonstrated high specificity (0.976), especially in patients under 16 (specificity 1.000).
- Logistic regression identified a combination of full extension, flexion, and supination as best predictors.
Conclusions:
- A two-tier clinical rule is proposed for elbow injury management.
- Patients under 16 with equal ROM may be safely discharged without radiographs.
- Normal extension, flexion, and supination indicate no need for emergent elbow radiographs.

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.

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: 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...
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.

The cervical plexus, formed by the anterior rami of the first four...

Anatomical Movements
Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist, metacarpophalangeal,...
