Fractures: Bone Repair01:27

Fractures: Bone Repair

3.7K
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...

Bones of the Upper Limb: Radius01:09

Bones of the Upper Limb: Radius

3.1K
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

2.8K
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...

Ankle Joint01:10

Ankle Joint

1.9K
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: Humerus01:19

Bones of the Upper Limb: Humerus

4.8K
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...

Bone Disorders01:29

Bone Disorders

4.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Summary

Navicular fractures, often from low-energy injuries, can be treated nonoperatively. Surgery may speed athlete recovery, while nonunion requires debridement and fixation.

Area of Science:

  • Orthopedic Surgery
  • Podiatric Medicine
  • Sports Medicine

Background:

  • The tarsal navicular bone is vital for hindfoot motion and Chopart joint function.
  • Navicular fractures encompass low-energy avulsions, displaced comminuted fractures, and stress fractures.
  • Müller-Weiss disease can mimic acute or stress navicular fractures with its characteristic fragmentation.

Purpose of the Study:

  • To review the diagnosis and management of acute and stress navicular fractures.
  • To discuss surgical and nonoperative treatment options for various navicular fracture types.
  • To highlight the differential diagnosis including Müller-Weiss disease.

Main Methods:

  • Review of current literature on navicular fractures and related conditions.
  • Analysis of treatment strategies based on fracture classification and severity.
  • Discussion of diagnostic challenges, particularly for stress fractures.

Main Results:

  • Low-energy dorsal avulsion fractures often respond well to nonoperative management.
  • Displaced, comminuted fractures necessitate surgical intervention, potentially including bone grafting and fixation.
  • Delayed diagnosis is common for stress fractures, though conservative treatment yields good outcomes; surgery offers faster return to sport.
  • Nonunion of acute or stress fractures requires surgical debridement, grafting, and stable fixation.

Conclusions:

  • Treatment for navicular fractures should be tailored to fracture type, displacement, and patient factors.
  • Early diagnosis and appropriate management are key to successful outcomes and return to activity.
  • Müller-Weiss disease presents a diagnostic challenge and requires careful consideration in cases of navicular fragmentation.
