Sciatica Causes
Osteophyte (Bone Spur)
Osteophyte also called a bone spur, is an abnormal bony growth on the bone’s surface usually triggered by inflammation or injuries. Bone spurs are often caused by arthritis (a condition when the joints get inflamed), typically asymptomatic and left undetected for several years.
Osteophytes are discovered when they tamper with other organs in the body, as is the case with sciatica. The osteophyte rests on the sciatic nerves, inhibiting the ordinary course of things causes different symptoms. [6]
Through joint inflammation, compression of the spinal cord or a nerve root, osteophyte may cause back pain. And when people have osteophyte in the lower spine, people may feel pain, weakness in one or both of legs, tingling in the buttocks and back of the thighs. But the pain will relief when flexing your waist or bending forward.
Some risk factors of osteophyte include joint degeneration, increased age, genetics, poor posture, disc degeneration, congenital skeletal abnormalities, and joint injury.
