Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

10.4K
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...

Muscles of the Forearm that Move the Hand and Fingers

2.9K
The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
Anterior Compartment
The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

Bones 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.
The radius has a nail-shaped head, and a...

Area of Science:

  • Orthopedic Surgery
  • Hand and Wrist Surgery
  • Sports Medicine

Background:

  • Acute extensor carpi ulnaris (ECU) subsheath injury or chronic insufficiency can lead to symptomatic ECU instability.
  • This instability often occurs at the distal ulna osseous sulcus.
  • Associated pathologies like triangular fibrocartilage complex tears and ECU tendinopathy may coexist.

Purpose of the Study:

  • To describe the surgical treatment for refractory extensor carpi ulnaris (ECU) instability.
  • To detail a specific reconstructive technique for ECU subsheath pathologies.

Main Methods:

  • Review of cases with symptomatic ECU instability.
  • Surgical intervention including direct subsheath repair or reconstruction with an extensor retinacular sling.
  • Detailed description of the extensor retinacular sling technique.

Main Results:

  • Surgical treatment is indicated for cases refractory to nonoperative management.
  • Reconstruction using a radially based extensor retinacular sling is a common surgical approach.
  • The study details a specific technique for ECU subsheath reconstruction.

Conclusions:

  • Extensor carpi ulnaris (ECU) subsheath injuries and insufficiency are significant causes of wrist instability.
  • Surgical reconstruction, particularly with an extensor retinacular sling, offers a solution for refractory cases.
  • The described technique provides a method for addressing ECU subsheath pathologies and restoring wrist stability.
