Bone Formation by Intramembranous Ossification01:29

Bone Formation by Intramembranous Ossification

16.1K
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into ...

Secondary Spinal Cord Injury llI: Pathophysiology

52
Early Ischemia and Ionic ImbalanceWithin minutes of spinal cord injury, a secondary cascade begins, progressing over hours to weeks. Vascular damage reduces blood flow, causing ischemia and mitochondrial dysfunction. ATP depletion leads to ion pump failure, membrane depolarization, sodium influx, potassium efflux, and water accumulation, resulting in cellular swelling. Increased intracellular calcium further disrupts mitochondria and accelerates cellular injury.Excitotoxicity and Neuronal...

Neurogenesis and Regeneration of Nervous Tissue

2.1K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

15.4K
Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...

Bone Formation by Endochondral Ossification01:24

Bone Formation by Endochondral Ossification

14.6K
Bone formation, or ossification, begins around the sixth to seventh week of embryonic development. Most bones develop from a cartilaginous template through the process of endochondral ossification. Cartilage formation begins when clusters of mesenchymal cells differentiate into chondrocytes. These chondrocytes proliferate rapidly and secrete an extracellular matrix that becomes encased in a membrane called the perichondrium. The resulting cartilage model provides a template that resembles the...

Neurulation01:30

Neurulation

40.2K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

Summary
This summary is machine-generated.

Heterotopic ossification (HO) is bone growth in soft tissues after neurological injury, causing joint stiffness. Current treatments like ethane-1-hydroxy-1,1-diphosphonic acid show limited effectiveness, necessitating further research.

Area of Science:

  • Neurology
  • Orthopedics
  • Pathology

Background:

  • Heterotopic ossification (HO) involves abnormal bone formation in soft tissues, often following neurological injuries like spinal cord or head trauma.
  • This condition can lead to joint ankylosis, significantly impairing patient mobility and presenting with local inflammatory signs.

Purpose of the Study:

  • To review the current understanding of heterotopic ossification (HO) following neurological injury.
  • To discuss diagnostic methods, pathogenesis, and treatment strategies for HO.
  • To highlight the need for further research into etiology, diagnosis, and treatment efficacy.

Main Methods:

  • Review of existing literature on heterotopic ossification (HO).
  • Discussion of diagnostic modalities including Technetium 99 bone scan and X-ray.
  • Analysis of current and potential therapeutic interventions.

Main Results:

  • HO is characterized by soft tissue bone formation, joint ankylosis, and inflammation.
  • Diagnosis is aided by bone scans and X-rays; serum alkaline phosphatase may be elevated.
  • Ethane-1-hydroxy-1,1-diphosphonic acid is indicated but has limited efficacy; NSAIDs, warfarin, and X-radiation show promise.

Conclusions:

  • The pathogenesis of HO remains unclear, despite its resemblance to myositis ossificans traumatica.
  • Joint exercise is recommended to maintain range of motion.
  • Further studies are crucial for understanding HO etiology, improving diagnosis, predicting recurrence, and evaluating treatment effectiveness.
