Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder causing bone formation in soft tissues. This case highlights FOP exacerbation following a surgical procedure.
Area of Science:
- Medical Genetics
- Rare Diseases
- Skeletal Biology
Background:
- Fibrodysplasia ossificans progressiva (FOP) is a rare genetic disorder.
- Characterized by progressive heterotopic ossification and congenital limb abnormalities.
- Leads to significant disability and reduced quality of life.
Observation:
- A 33-year-old female patient presented with classic clinical and radiological signs of FOP.
- Congenital bilateral hallux valgus noted at birth.
- Progressive ossification of the left scapula occurred by age 10, followed by numerous disease exacerbations.
Findings:
- The patient experienced a notable exacerbation of FOP symptoms after undergoing a surgical operation.
- This observation suggests a potential trigger for disease flare-ups in FOP patients.
Implications:
- Highlights the importance of careful management and monitoring of FOP patients, especially around surgical interventions.
- Suggests a need for further research into FOP exacerbation triggers.
- Informs clinical practice regarding potential risks associated with surgery in FOP patients.

Bone Disorders
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...

Fractures: Bone Repair
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 procedure...

Spongy 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...
