Abstract
Cubitus varus deformity of the elbow may not only cause cosmetic problems, but delayed functional deficiencies also. This case report demonstrated delayed posterolateral rotatory instability due to lateral collateral ligament complex avulsion long after posttraumatic cubitus varus. Satisfactory results were obtained using cubitus varus correction and reattachment of the lateral collateral ligament complex to the lateral epicondyle of the humerus.
