Cubitus varus is a medical condition characterized by inward angulation of the forearm. It is a common complication following supracondylar fractures of the humerus in children. The condition is also known as gunstock deformity due to the arm's resemblance to the stock of a rifle.

Causes

The primary cause of cubitus varus is malunion of a supracondylar fracture of the humerus. This can occur due to improper alignment during the healing process. Other causes include congenital deformities and certain bone diseases.

Symptoms

The most noticeable symptom of cubitus varus is the inward angulation of the forearm. This can lead to functional limitations, such as difficulty in extending the arm fully. Other symptoms may include pain, instability, and decreased strength in the arm.

Diagnosis

Diagnosis of cubitus varus is primarily based on physical examination and imaging studies. X-rays are commonly used to confirm the diagnosis and assess the severity of the deformity.

Treatment

Treatment for cubitus varus depends on the severity of the deformity and the patient's symptoms. Non-surgical treatments include physical therapy and the use of orthotic devices. In severe cases, surgery may be required to correct the deformity.
