Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

3.8K
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: Radius

4.1K
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...

Ankle Joint01:10

Ankle Joint

2.4K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

664
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Summary

The distal radioulnar joint is prone to instability due to ligament damage, often requiring reconstructive surgery when ligaments cannot be repaired. This instability impacts wrist function, causing pain and weakness.

Area of Science:

  • Orthopedic Surgery
  • Biomechanics
  • Musculoskeletal Research

Background:

  • The distal radioulnar joint (DRUJ) is crucial for forearm rotation and wrist function.
  • Its inherent instability is primarily managed by ligamentous structures.
  • Disruptions to these stabilizers can arise from trauma, leading to significant functional deficits.

Purpose of the Study:

  • To review the causes and consequences of distal radioulnar joint instability.
  • To discuss the implications of untreated DRUJ instability on wrist and forearm kinematics.
  • To highlight the role of reconstructive procedures in managing chronic, irreparable ligament injuries.

Main Methods:

  • Literature review of studies on distal radioulnar joint anatomy, biomechanics, and injury patterns.
  • Analysis of clinical outcomes related to untreated DRUJ instability.
  • Examination of reconstructive techniques for chronic DRUJ instability.

Main Results:

  • Distal radioulnar joint instability results from dislocations, fractures, ligament injuries, or malunions.
  • Untreated instability leads to altered wrist and forearm kinematics, causing pain, weakness, and potential arthritis.
  • Chronic cases often require ligament reconstruction due to irreparable native tissues.

Conclusions:

  • Distal radioulnar joint instability is a significant clinical problem with functional consequences.
  • Early recognition and management are essential to prevent long-term morbidity.
  • Surgical reconstruction is a viable option for chronic instability when ligament repair is not feasible.
