Cubitus Varus deformity.
- It is a common deformity in which the extended forearm is deviated towards midline of the body.(with the arm extended at the side and the palm facing forward, the forearm and hand are held at less than 5 degrees)
- Cubitus varus is often referred to as “Gunstock deformity”, due to the crooked nature of the healing.
- A common cause is the supracondylar fracture of humerus. These deformities are most commonly result of malunion.
- Cubitus varus mostly presents as cosmetic deformity but it may also cause posterolateral instability, increased risk of secondary fractures, tardy ulna nerve palsy and snapping elbow.
- Treatment: surgical correction for cubitus varus deformity in form of supracondylar osteotomy of the humerus.
