Learn About Toxic Synovitis
Toxic synovitis is a condition affecting children that causes hip pain and limping.

Toxic synovitis occurs in children before puberty. It usually affects children from 2 to 12 years old. It is a type of inflammation of the hip. Its cause is not known. Boys are affected more often than girls. It can also occur after a common cold or viral infection.
Symptoms may include:

- Limp
- Thigh pain, in front and toward the middle of the thigh
- Knee pain
- Low-grade fever, less than 101°F (38.33°C)
