Self-releasing of a titanium clamp (CranioFix) in cranioplasty.

The CranioFix titanium clamp was developed for fixing bone flaps after craniotomy. In this case, to prevent cosmetic problems, the bone flaps were trimmed with a beveled edge, and a CranioFix clamp was used for bone flap fixation. As the brain swelled, the CranioFix clamp became loosened. If brain swelling is anticipated and bone margins have been trimmed, it may be better to consider other fixation methods.
