Blount's disease is a growth disorder that affects the bones of the lower leg, causing them to bow outward. This condition is named after the American orthopedic surgeon, Walter Putnam Blount (1900–1992), who described it in detail in the year 1937.
Etiology[edit]
The exact cause of Blount's disease is unknown. However, it is believed to be due to a combination of genetic and environmental factors. Some researchers suggest that it may be related to an abnormality in the growth plate of the tibia, the larger of the two bones in the lower leg.
Symptoms[edit]
The most noticeable symptom of Blount's disease is a noticeable bowing of the leg below the knee. This can occur in one or both legs. Other symptoms may include knee pain, difficulty walking, and a noticeable difference in leg length.
Diagnosis[edit]
Blount's disease is typically diagnosed through a combination of physical examination and imaging tests. During the physical examination, the doctor will look for signs of bowing in the legs. Imaging tests, such as x-rays, can help confirm the diagnosis and determine the severity of the condition.
Treatment[edit]
Treatment for Blount's disease depends on the severity of the condition and the age of the patient. In mild cases, especially in young children, the condition may correct itself over time. In more severe cases, treatment may include the use of braces or surgery to correct the bowing.
Prognosis[edit]
With early diagnosis and treatment, most children with Blount's disease are able to lead normal, active lives. However, if left untreated, the condition can lead to long-term complications, such as arthritis and difficulty walking.
