Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

10.8K
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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.5K
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

13.5K
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...

Area of Science:

  • Orthopedics
  • Emergency Medicine
  • Hand Surgery

Background:

  • Wrist injuries are frequent in emergency departments.
  • Carpal bone disruptions can lead to impaired hand function, pain, and weakness.
  • Scapholunate dissociation is a prevalent carpal instability with potential for severe morbidity.

Purpose of the Study:

  • To highlight the importance of recognizing high-risk injury mechanisms for scapholunate dissociation.
  • To emphasize the subtle clinical manifestations that aid in early diagnosis.
  • To guide emergency practitioners in the timely management of this injury.

Main Methods:

  • Review of common wrist injury presentations in emergency settings.
  • Analysis of diagnostic challenges associated with subtle findings.
  • Correlation of injury mechanisms with clinical signs of scapholunate dissociation.

Main Results:

  • Scapholunate dissociation can result in avascular necrosis, delayed healing, functional limitations, and arthritis.
  • Diagnostic findings for this injury can be easily overlooked.
  • Identifying specific injury patterns and symptoms improves diagnostic accuracy.

Conclusions:

  • Early identification of high-risk injury mechanisms is key for diagnosing scapholunate dissociation.
  • Awareness of subtle clinical signs assists emergency practitioners in prompt diagnosis.
  • Timely diagnosis and treatment are essential to mitigate morbidity associated with scapholunate dissociation.
