Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

5.8K
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: Ulna01:15

Bones of the Upper Limb: Ulna

3.4K
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...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

3.8K
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.
The radius has a nail-shaped head, and a...

Summary
This summary is machine-generated.

Luxatio erecta humeri, a rare shoulder dislocation, presents with arms abducted. Radiographs clearly show this distinct inferior glenohumeral joint dislocation, aiding diagnosis.

Area of Science:

  • Orthopedic Surgery
  • Radiology
  • Emergency Medicine

Background:

  • Luxatio erecta humeri is an uncommon type of shoulder dislocation.
  • It is characterized by the humeral head dislocating inferiorly, below the glenoid rim.
  • This injury typically results from significant trauma, often with the arm in abduction.

Purpose of the Study:

  • To describe the clinical presentation and radiographic findings of luxatio erecta humeri.
  • To review the potential complications associated with this injury.
  • To illustrate a case of bilateral luxatio erecta humeri.

Main Methods:

  • Case presentation of a middle-aged male with bilateral shoulder trauma.
  • Review of clinical findings including arm position and pain.
  • Analysis of radiographic images demonstrating inferior glenohumeral joint dislocation.

Main Results:

  • The patient presented with bilateral shoulder pain and arms held in abduction.
  • Radiographs confirmed bilateral inferior dislocation of the glenohumeral joints.
  • The humeral shaft was observed to be parallel to the scapular spine, a hallmark finding.

Conclusions:

  • Luxatio erecta humeri has a characteristic clinical and radiographic presentation.
  • Radiographs are crucial for diagnosing this inferior shoulder dislocation.
  • Understanding the hallmark findings aids in prompt and accurate diagnosis and management.
