Postoperative lead migration in deep brain stimulation surgery: Incidence, risk factors, and clinical impact
Fig 6
Illustration of a tensile force applied at the DBS connector site resulting in dorsal migration of the intracranial lead.
After a few weeks of healing, scalp tethering prevents the subgaleal loops in the lead from uncoiling and results in coaxial transmission of the tension all the way to the StimLoc cap and, if the cap fixation fails, the intracranial lead is displaced.
