Summary
Elbow instability arises from damage to bony and ligamentous stabilizers. This review details diagnostic maneuvers and testing for identifying elbow instability patterns based on anatomy and biomechanics.
Area of Science:
- Orthopedics
- Biomechanics
- Anatomy
Background:
- The elbow joint relies on bony and ligamentous structures for stability.
- Trauma and overuse can disrupt these stabilizers, leading to instability patterns.
Purpose of the Study:
- To review the anatomy and biomechanics of the elbow.
- To outline diagnostic maneuvers and testing for elbow instability.
Main Methods:
- Literature review of elbow anatomy, biomechanics, and instability.
- Description of clinical examination techniques for elbow instability.
Main Results:
- Elbow stability is maintained by a complex interplay of bony and ligamentous restraints.
- Specific examination maneuvers and tests aid in diagnosing distinct elbow instability patterns.
Conclusions:
- Understanding elbow anatomy and biomechanics is crucial for diagnosing instability.
- Systematic evaluation using specific maneuvers and tests enables accurate diagnosis of elbow instability.

01:09Bones of the Upper Limb: Radius
10.7K
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.

01:15Bones of the Upper Limb: Ulna
10.3K
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...

01:19Bones of the Upper Limb: Humerus
13.2K
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...

00:51Anatomical Movements
16.8K
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,...
