Muscles of the Forearm that Move the Hand and Fingers01:17

Muscles of the Forearm that Move the Hand and Fingers

1.2K
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...

Ankle Joint01:10

Ankle Joint

1.7K
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...

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...

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

1.5K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...

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...

Functional Classification of Joints01:09

Functional Classification of Joints

4.4K
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
An...

Area of Science:

  • Orthopedics
  • Hand Surgery
  • Biomechanics

Background:

  • Midcarpal instability is an uncommon condition affecting the wrist's midcarpal joint.
  • It is also referred to as carpal instability nondissociative, adding to diagnostic confusion.
  • Despite being described decades ago, it is not widely understood by clinicians.

Purpose of the Study:

  • To provide a comprehensive overview of midcarpal instability.
  • To detail the history, pathomechanics, classification, and treatment options.
  • To improve clinician recognition and treatment decision-making for this disorder.

Main Methods:

  • Literature review focusing on the history and evolution of understanding midcarpal instability.
  • Analysis of pathomechanics and biomechanical factors contributing to the condition.
  • Review of current and historical classification systems.
  • Summary of established and emerging treatment strategies.

Main Results:

  • The condition has a long history but remains under-recognized.
  • Understanding the etymology and kinematics is crucial for diagnosis.
  • Pathomechanics involve complex interactions within the carpal bones.
  • A clear classification system and effective treatment protocols are still evolving.

Conclusions:

  • Enhanced understanding of midcarpal instability's history and kinematics is needed.
  • Improved recognition and standardized treatment approaches are essential.
  • Further research into pathomechanics and treatment efficacy is warranted.
