Spinal Nerves: Plexus I01:22

Spinal Nerves: Plexus I

1.2K
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
The cervical plexus, formed by the anterior rami of the first four...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

2.4K
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...

Changes in the Appendicular Skeleton with Age

2.2K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Neurulation01:30

Neurulation

42.2K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Muscles that Move the Forearm01:16

Muscles that Move the Forearm

1.8K
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...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

2.3K
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...

This summary is machine-generated.

A 14-week-old infant presented with limited forearm rotation due to radioulnar synostosis. This congenital condition involves the bony fusion of the radius and ulna bones in the elbow.

Area of Science:

  • Pediatric Orthopedics
  • Congenital Abnormalities
  • Skeletal Development

Context:

  • A 14-week-old infant presented with an abnormal pronated right arm.
  • Physical examination revealed limited forearm pronation and supination.
  • This clinical presentation prompted surgical referral.

Purpose:

  • To diagnose and characterize radioulnar synostosis in an infant.
  • To highlight the diagnostic utility of conventional radiography.
  • To underscore the importance of early identification of congenital limb abnormalities.

Summary:

  • Conventional radiography confirmed a bony fusion of the proximal radius and ulna.
  • The diagnosis was identified as radioulnar synostosis.
  • This condition explains the infant's limited forearm rotational movement.

Impact:

  • Early diagnosis of radioulnar synostosis is crucial for appropriate orthopedic management.
  • Understanding this congenital anomaly aids in predicting functional outcomes.
  • This case contributes to the literature on pediatric upper limb congenital conditions.
