Fractures: Bone Repair01:27

Fractures: Bone Repair

5.5K
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...

Two structural features of the DNA molecule provide a basis for the mechanisms of heredity: the four nucleotide bases and its double-stranded nature. The Watson-Crick model of double-helical DNA structure, proposed in 1952, drew heavily upon the X-ray crystallography work of researchers Rosalind Franklin and Maurice Wilkins. Watson, Crick, and Wilkins jointly received the Nobel Prize in Physiology or Medicine for their work in 1962. Franklin was, controversially, excluded from the prize for...

Overview of DNA Repair

In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

The human nervous system handles vast amounts of information by translating sensory stimuli into neural impulses, which the brain processes, creating thoughts expressed through language or stored as memories. The brain also synthesizes information from emotions and memories, which significantly influence thoughts and behaviors. This intricate process creates a comprehensive mental picture.
The brain organizes this information using concepts, which are mental categories grouping linguistic data,...

Summary

Three-dimensional (3-D)-printed short-segment templates offer a cost-effective and time-efficient solution for complex mandibular fracture repair. These patient-specific templates aid in precise plate contouring, potentially reducing operating time and costs.

Area of Science:

  • Maxillofacial surgery
  • Biomedical engineering
  • 3D printing applications

Background:

  • Contouring fracture plates for complex mandibular fractures can be time-consuming.
  • Preoperative planning is crucial for successful mandibular fracture repair.

Purpose of the Study:

  • To evaluate the feasibility of using 3-D-printed short-segment mandibular templates for complex mandibular fracture management.
  • To assess the time efficiency and cost-effectiveness of these templates compared to traditional methods.

Main Methods:

  • A feasibility study utilized maxillofacial computed tomography data from 3 patients with comminuted mandibular fractures.
  • 3-D models were segmented and used to create patient- and site-specific short-segment templates.
  • Fracture plates were contoured using these templates in a simulated preoperative setting.

Main Results:

  • 3-D template printing took under 3 hours per template.
  • Precontouring plates with templates saved a median of 5-7 minutes intraoperatively per segment.
  • 3-D templates cost less than $20, compared to approximately $2200 for a complete model.

Conclusions:

  • Patient- and site-specific 3-D-printed short-segment templates are feasible for complex mandibular fracture repair.
  • These templates are cost-efficient and facilitate plate contouring effectively.
  • Further studies are warranted to confirm reduced operative costs and time in clinical practice.
