Symptoms of subchondral sclerosis include pressure and pain within the bone, explains Carol Eustice for About.com. Some physical signs of the condition are thicker bone density and increased blood flow.
Subchondral sclerosis is a condition often associated with osteoarthritis in which the subchondral layer of bone hardens, thickens and develops cysts, according to Eustice. The cysts and increased bone density put pressure on the nerves, manifesting as arthritis pain. This condition is usually diagnosed with X-rays. The bone with subchondral sclerosis appears white under imaging scans because the bone is more dense than the rest of the bone.
Osteoarthritis, a degeneration of bones, joint and cartilage, is most often the culprit for subchondral sclerosis, states Johns Hopkins Arthritis Center. Early in the disease development, individuals most often experience joint pain; joint problems such as joint locking; and stiffness that usually increases at the end of the day or after excessive activity. Other than subchondral sclerosis, other symptoms and signs of osteoarthritis are bony enlargements of the joint and joint tenderness. As the disease progresses, range of motion is affected, gradually followed by edema or fluid in the joint and cysts. Osteoarthritis occurs mostly in the fingers, at the base of the thumb, in the knees and at the hips.
