Fractures: Bone Repair01:27

Fractures: Bone Repair

4.3K
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...

Bone Remodeling01:40

Bone Remodeling

39.4K
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.

Growth of Cartilage and Bone Tissue

3.8K
Chondrocytes form a temporary cartilaginous model by dividing and secreting a thick gel-like extracellular matrix. Once the chondrocytes undergo programmed cell death, osteoblasts enter the site of the cartilaginous model. The process of replacing the temporary cartilaginous model with bone in an ordered manner is called endochondral ossification. In endochondral ossification, not all of the cartilage is replaced by bone tissue. Some cartilage that performs a protective and supportive function...

Area of Science:

  • Orthopedics and Sports Medicine
  • Biomedical Engineering
  • Health Services Research

Background:

  • Fracture nonunion presents a significant clinical challenge, impacting patient recovery and healthcare costs.
  • Estimating nonunion incidence requires robust methodologies, especially when considering real-world treatment variations.
  • The EXOGEN Ultrasound Bone Healing System is a non-invasive device used to promote bone healing.

Purpose of the Study:

  • To estimate the incidence of fracture nonunions in patients treated with the EXOGEN Ultrasound Bone Healing System compared to standard care.
  • To outline the design and methodology of the Bioventus Observational Noninterventional EXOGEN Studies (BONES) Program, focusing on the fifth metatarsal fracture study.
  • To support a potential US Food and Drug Administration (FDA) label expansion for the EXOGEN system through robust real-world evidence.

Main Methods:

  • Employed an external comparator design with two cohorts: EXOGEN-treated patients in a registry and comparator patients from a health claims database.
  • Utilized International Classification of Diseases, Tenth Revision (ICD-10) nonunion diagnosis codes as the primary outcome measure.
  • Integrated multiple data sources, including medical records, patient-reported data, device usage, and claims data, for comprehensive analysis.

Main Results:

  • The BONES Program successfully implemented a complex, multi-component study design to evaluate fracture nonunion incidence.
  • The study design facilitated the collection of real-world evidence, addressing the limitations of randomized clinical trials in this context.
  • Data integration from diverse sources aimed to provide a broader understanding of factors influencing nonunion development.

Conclusions:

  • The innovative design of the BONES Program allowed for the evaluation of EXOGEN's effect on mitigating nonunions in a real-world setting.
  • The study provides valuable real-world evidence for regulatory decision-making regarding the EXOGEN Ultrasound Bone Healing System.
  • The program's methodology supports the assessment of patient experience and treatment effectiveness outside of traditional clinical trial parameters.
