Functional Classification of Joints01:09

Functional Classification of Joints

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses  or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Bone Disorders

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...

Diagnosing bone and joint infections is challenging. While labeled leukocytes are a gold standard, advanced imaging like technetium-99m-labeled antigranulocyte antibody scintigraphy offers alternatives for specific infections.

Area of Science:

  • Orthopedics
  • Nuclear Medicine
  • Radiology

Background:

  • Bone and joint infections, including osteomyelitis and septic arthritis, pose significant diagnostic and therapeutic challenges.
  • Soft-tissue infections such as cellulitis, fasciitis, and abscesses often accompany bone and joint infections, requiring prompt management.

Purpose of the Study:

  • To review diagnostic imaging modalities for bone and joint infections.
  • To highlight the strengths and limitations of various techniques in identifying infectious foci within the musculoskeletal system.

Main Methods:

  • Bone scintigraphy is a sensitive tool for detecting bone and joint infections.
  • Labeled leukocyte scintigraphy is considered a gold standard but has limitations in imaging chronic infections and the axial skeleton.

  • Technetium-99m-labeled antigranulocyte antibody scintigraphy is useful for peripheral osteomyelitis.
  • Magnetic resonance imaging (MRI) excels at identifying abscesses but may struggle to delineate the full extent of infection due to hyperemia.

    • Main Results:

    • Labeled leukocyte imaging is effective but limited for chronic or axial skeletal infections.
    • (99m)Tc-labeled antigranulocyte antibody scintigraphy shows promise for peripheral osteomyelitis.
    • MRI effectively detects abscesses but can be less precise in defining infection spread.

    Conclusions:

    • Accurate diagnosis of musculoskeletal infections requires careful consideration of imaging modality strengths and weaknesses.
    • A combination of imaging techniques may be necessary for comprehensive evaluation.
    • Further research into advanced imaging may improve diagnostic accuracy and patient outcomes.
