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

Muscles of the Forearm that Move the Hand and Fingers

2.1K
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...

Fractures: Bone Repair

4.4K
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

Flail Chest-I

Overview of Flail Chest
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...

Bones of the Upper Limb: Radius01:09

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...

Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

3.7K
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...

Flail Chest-II

391
Managing flail chest, a condition characterized by a segment of the chest wall moving independently from the rest of the thoracic cage, requires a comprehensive approach. It includes a thorough assessment of the patient's condition, a diagnostic evaluation to determine the extent of the injury, and the implementation of appropriate medical interventions tailored to the individual's needs.

Summary

Metacarpal fractures are common hand injuries. Treatment ranges from non-operative methods for stable fractures to surgery for unstable or intra-articular fractures, prioritizing early mobilization.

Area of Science:

  • Orthopedic Surgery
  • Hand Surgery
  • Traumatology

Background:

  • Metacarpal fractures represent a frequent occurrence in hand injuries.
  • Treatment decisions depend on fracture stability and intra-articular involvement.

Purpose of the Study:

  • To review current management strategies for metacarpal fractures.
  • To outline indications for operative versus non-operative treatment.
  • To emphasize the importance of early mobilization and specialist referral.

Main Methods:

  • Review of literature on metacarpal fracture management.
  • Analysis of treatment outcomes based on fracture type and stability.
  • Guidelines for surgical intervention and conservative care.

Main Results:

  • Stable, extra-articular metacarpal fractures often managed non-operatively with splinting and buddy taping.
  • Unstable, displaced, or intra-articular metacarpal fractures typically necessitate surgical osteosynthesis.
  • Early mobilization is a key goal across all treatment modalities.

Conclusions:

  • Non-operative treatment is suitable for stable, extra-articular metacarpal fractures.
  • Operative intervention is indicated for unstable/displaced extra-articular and most intra-articular fractures.
  • Referral to a hand surgeon is recommended for intra-articular, open, and pediatric metacarpal fractures due to potential for poor outcomes.
