The clamps and pins are indicated for use in open and percutaneous craniotomies as well as spinal surgery when rigid skeletal fixation is necessary.

The CT/MRI-compatible model and the Titanium or PEEK + Titanium Skull Pins are used when intra-operative imaging is required.

The mb-FIX Cranial Stabilization System provides an interface for accessories like retractor systems, navigation adaptors or other items.

Indications for use as stated in the FDA summary.
