Fractures: Bone Repair01:27

Fractures: Bone Repair

6.1K
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...

Vertebral Column: Regions and Curvature01:16

Vertebral Column: Regions and Curvature

11.3K
The vertebral column or spine is a flexible column that supports the head, neck, and body and  allows for their movements. It also protects the spinal cord.
Regions of the Vertebral Column
In an adult, the spine is subdivided into five regions: the cervical, the thoracic, the lumbar, the sacral, and the coccygeal region. The spine initially develops as a series of 33 vertebrae; after 20 years of age, the nine bones in the sacral region, five sacral, and four coccygeal bones fuse to form...

Compact Bone01:27

Compact Bone

17.9K
Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone's overall function.
Compact bone, also called cortical bone, is the denser, stronger of the two types of bone tissue. It is found under the periosteum and in the diaphyses of long bones, where it provides support and protection. The microscopic structural unit of compact bone is called an osteon, or haversian system. Each osteon is composed of concentric rings of calcified...

Changes in the Appendicular Skeleton with Age

3.9K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Spongy Bone01:09

Spongy Bone

9.1K
All bones comprise an outer layer of compact bone, and an interior made up of spongy bone tissue, also called cancellous or trabecular bone. In long bones, spongy bone tissue is mainly found in the interior of the epiphyses (broad ends of the bone).
Spongy bone is more porous, and less dense compared to compact bone. It is composed of concentric lamellae that are arranged irregularly to form the trabecular network. In some bones, the spaces between trabeculae contain red marrow, where...

Bone Disorders01:29

Bone Disorders

5.8K
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

Osteogenesis imperfecta, a genetic collagen disorder, causes bone fragility and spinal issues like scoliosis. Early surveillance and specific treatments can manage these complex skeletal manifestations.

Area of Science:

  • Genetics
  • Orthopedics
  • Pediatrics

Background:

  • Osteogenesis imperfecta (OI) is a genetic disorder affecting type I collagen, leading to brittle bones.
  • While various genetic mutations exist, COL1A1 and COL1A2 gene mutations account for ~90% of OI cases.
  • OI is characterized by bone fragility, frequent fractures, and potential limb deformities.

Purpose of the Study:

  • To review the spinal manifestations of Osteogenesis Imperfecta.
  • To highlight the increased incidence of specific spinal pathologies in OI patients.
  • To discuss management and surveillance strategies for spinal complications in OI.

Main Methods:

  • Literature review of Osteogenesis Imperfecta focusing on spinal involvement.
  • Analysis of reported spinal pathologies including scoliosis, kyphosis, and craniocervical abnormalities.
  • Examination of treatment outcomes and recommended surveillance protocols.

Main Results:

  • Spinal involvement in OI includes scoliosis, kyphosis, craniocervical junction abnormalities, and lumbosacral pathology.
  • Patients with OI exhibit a higher incidence of lumbosacral spondylolysis and spondylolisthesis.
  • Diphosphonate use may reduce scoliosis progression; lateral cervical radiographs are advised for craniocervical abnormalities surveillance before age 6.

Conclusions:

  • Osteogenesis imperfecta presents significant spinal challenges beyond bone fragility.
  • Early detection and management of spinal deformities and abnormalities are crucial for patient outcomes.
  • Specialized intraoperative and anesthetic considerations are vital due to fracture risk and other complications in OI patients.
