Dislocation of the nail
In some patients, the sinus is injured in such a way that it cannot retain the nail plate in position and the nail plate is gently drawn into the sinus using a suture.
Use a 5 (0) nonresorbable nylon suture. Begin on the dorsal aspect proximal to the sinus and insert the needle so that it exits the sinus distal to the eponychium.
Pass the needle through one side of the proximal edge of the nail plate. Then pass the needle back through the other side of the nail plate and then through the sinus of the nail so that it exits parallel to the first pass of the stitch. The sutures should be separated from one another by approximately 5 mm.
Apply gentle traction on the sutures. This will draw the nail plate back into the sinus. Once the nail plate is securely in its bed, tie the suture over a cotton or foam ball to prevent pressure injury to the skin.
