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...
Muscles that Move the Forearm01:16

Muscles that Move the Forearm

The muscles that move the forearms can be divided into four groups: forearm flexors, forearm extensors, forearm pronators, and forearm supinators. The flexors and extensors act on the elbow joint, while the pronators and supinators act on the radioulnar joints.
Forearm Flexors
The biceps brachii, brachialis, and brachioradialis are forearm flexors. The biceps brachii is made up of two heads. Its long head originates at the supraglenoid tubercle of the scapula, whereas that of the short head is...
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...
Muscles of the Forearm that Move the Hand and Fingers01:16

Muscles of the Forearm that Move the Hand and Fingers

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 radialis,...
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
  • Traumatology
  • Biomaterials Engineering

Background:

  • Diaphyseal fractures of the radius and ulna are common orthopedic injuries.
  • Traditional fixation methods like plating have established protocols.
  • Intramedullary nailing offers an alternative fixation strategy with potential benefits.

Purpose of the Study:

  • To evaluate the clinical and radiological outcomes of treating diaphyseal radius and ulna fractures using interlocking intramedullary nails.
  • To compare the efficacy and complication rates of intramedullary nailing versus other fixation methods.

Main Methods:

  • Retrospective study of 78 patients (118 fractures) treated with ForeSight intramedullary nails between 2001 and 2005.
  • Average follow-up of 25 months, assessing bone healing, functional outcomes (Anderson score), and complications.
  • Radiological and functional evaluations were performed postoperatively.

Main Results:

  • Average bone healing time was 14.2 weeks, with no pseudo-arthrosis.
  • 88.6% of patients achieved a full range of motion; 10.1% had mild restriction.
  • Complications included 1 superficial infection, 3 incomplete radio-ulnar synostosis, and 1 compartment syndrome.

Conclusions:

  • Intramedullary nailing provides comparable results to plating for forearm fractures.
  • Nailing is particularly advantageous for open, serial, and comminuted forearm fractures.
  • This technique demonstrates a favorable safety and efficacy profile for complex diaphyseal fractures.
