Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

14.7K
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...

Analgesia and Pain Management

3.1K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Knee Joint01:23

Knee Joint

3.7K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

Nociception01:44

Nociception

34.8K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

Area of Science:

  • Rheumatology
  • Pain Medicine
  • Neuroscience

Background:

  • Osteoarthritis (OA) is a prevalent condition characterized by significant pain.
  • Pain is the primary symptom of OA, arising from peripheral and central neurological pathways.
  • OA pain originates from nerve endings in joint tissues like synovium and bone, excluding cartilage.

Purpose of the Study:

  • To elucidate the complex mechanisms underlying osteoarthritis pain.
  • To highlight the involvement of both nociceptive and neuropathic processes in OA pain.
  • To emphasize the need for tailored therapeutic strategies based on precise clinical assessment.

Main Methods:

  • Review of current literature on OA pain mechanisms.
  • Analysis of peripheral and central neurological pathways involved in OA pain.
  • Exploration of factors influencing OA pain perception and intensity.

Main Results:

  • OA pain involves both peripheral nociception and central nervous system modifications.
  • Neuromediators like nerve growth factor (NGF) play a role in OA pain signaling.
  • OA pain is a complex, heterogeneous condition influenced by various factors, not solely joint degradation.

Conclusions:

  • Osteoarthritis pain is a multifaceted condition with both nociceptive and neuropathic components.
  • Pain intensity in OA does not consistently correlate with the degree of joint degradation.
  • Precise clinical evaluation is essential for developing specific and effective OA pain management strategies.
