Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

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 short...
Bones of the Upper Limb: Ulna01:15

Bones of the Upper Limb: Ulna

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 of the...
Fractures: Bone Repair01:27

Fractures: Bone Repair

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 procedure...
Arteries of the Upper Limbs01:12

Arteries of the Upper Limbs

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...
Bones of the Upper Limb: Humerus01:19

Bones of the Upper Limb: Humerus

The upper limb consists of the arm, forearm, wrist, and hand bones. The humerus is the single bone of the upper arm region. Proximally, it has a large, spherical, smooth head that articulates with the glenoid cavity of the scapula to form the glenohumeral or shoulder joint. The margin of the head is the anatomical neck, a residual epiphyseal plate. Laterally it extends to form bony projections called the greater tubercle and the lesser tubercle. Next to the tubercles is the surgical neck, a...

Area of Science:

  • Orthopedic surgery
  • Geriatric medicine
  • Bone health

Background:

  • Distal radius fractures are prevalent, particularly in the elderly.
  • Fracture severity and clinical outcomes correlate significantly with bone mineral density.
  • Treatment decisions are influenced by patient bone health.

Purpose of the Study:

  • To review treatment options for distal radius fractures.
  • To highlight the role of bone mineral density in fracture management.
  • To discuss considerations for operative intervention.

Main Methods:

  • Review of nonoperative management (closed treatment with casting).
  • Overview of operative techniques including pinning, external fixation (bridging and nonbridging, arthroscopic-assisted), and open reduction internal fixation.
  • Emphasis on fracture characteristics and surgeon experience in treatment selection.

Main Results:

  • Bone mineral density is a critical factor in assessing distal radius fracture severity.
  • Clinical results are directly dependent on the patient's bone mineral density.
  • Multiple surgical and non-surgical treatment modalities are available.

Conclusions:

  • Bone mineral density is a key determinant in managing distal radius fractures.
  • Treatment selection requires careful consideration of fracture type, bone health, and surgical expertise.
  • Optimizing outcomes necessitates personalized treatment strategies based on these factors.
