Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.2K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.1K
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: Humerus01:19

Bones of the Upper Limb: Humerus

3.1K
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...

Fractures: Bone Repair01:27

Fractures: Bone Repair

3.1K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Muscles that Move the Forearm01:16

Muscles that Move the Forearm

1.4K
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...

Functional Classification of Joints01:09

Functional Classification of Joints

3.9K
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.
Synarthrosis

Area of Science:

  • Orthopedic Surgery
  • Trauma Care
  • Musculoskeletal Injuries

Background:

  • Motorcycle accidents are a common cause of severe trauma.
  • Wrist injuries, including distal radius fractures and distal radioulnar joint dislocations, can significantly impair function.

Purpose of the Study:

  • To report a case of complex wrist trauma in a young adult.

Main Methods:

  • Case report of a 30-year-old male with motorcycle accident-related wrist injury.
  • Emergency department evaluation and diagnosis of open distal radius fracture and distal radioulnar joint dislocation.
  • Surgical fixation to address the fracture and joint instability.

Main Results:

  • Successful surgical intervention was performed.
  • The patient's wrist mobility was restored post-surgery.

Conclusions:

  • Prompt surgical fixation is crucial for managing open distal radius fractures with associated joint dislocations.
  • Effective treatment can lead to restoration of function in complex wrist trauma cases.
