Hook nail deformity repaired using a composite toe graft

The hook nail deformity is caused by loss of fingertip bone and soft tissue. Healing can result in a volarly displaced distal nailbed and a tight tip with inadequate padding and a poor cosmetic appearance. A composite graft from the second toe placed beneath the released nailbed gives good support and improved pulp substance. The technique of the composite toe graft has been performed in nine patients. All grafts were 100 percent viable, but one patient required a second graft for additional tip bulk. There has been no donor-site morbidity in the follow-up of 1 month to 2 years.
