Cubitus varus

Cubitus Varus

Cubitus varus (pronunciation: kyo͞o'bĭ-təs vâr'əs) is a medical condition characterized by inward angulation of the forearm in relation to the upper arm when the arm is fully extended. It is also commonly referred to as 'gunstock deformity' due to its resemblance to the shape of an old-fashioned gunstock.

Etymology

The term 'cubitus varus' is derived from Latin, where 'cubitus' refers to the elbow, and 'varus' means bent inward.

Causes

Cubitus varus is most commonly caused by malunion of a supracondylar fracture of the humerus, the long bone in the upper arm. This is a common injury in children. Other causes can include congenital deformities and certain neuromuscular disorders.

Symptoms

The most noticeable symptom of cubitus varus is the visible inward angulation of the forearm. This can lead to functional limitations, such as difficulty in extending the arm fully. In some cases, it can also cause nerve damage, leading to weakness or numbness in the hand.

Treatment

Treatment for cubitus varus typically involves surgery to correct the angle of the arm. This is usually done through a procedure known as an osteotomy, where the bone is cut and realigned.
