The fingertip injuries are the most common type of hand injuries and are often followed by hook nail deformity. It is caused by the loss of bone and soft tissue of fingertip. The healed fingertips usually have a volarly displaced distal nailbed and a tight, painful tip with an inadequate padding and a hook-like nail. To correct the deformity, it is necessary to release the distal nailbed completely, reposition it to the normal site, and provide adequate support for maintaining correction of the volarly deformed nail. We experienced twelve cases of hook nail deformity after fingertip injury. They have been treated with cross finger flap. Autogenous iliac bone graft was applied for lengthening in nine cases. After the correction of hook nail deformity, the results were satisfactory in all cases. According to this results, we consider that the cross finger flap with iliac bone graft is a safe and reliable procedure which shows not only a high survival rate, but also excellent function and aesthetic outcomes in correction of hook nail deformity.
Key Words: Hook nail, Iliac bone graft, Cross finger flap
